BACKGROUND ART In general, for the purpose of carrying out a communication line setting work, such as telephone line setting work, workers need multiple kinds of tools, for instance wrapping wire, a wrapping socket for installation of a terminal box, a screw driver for screwing or unscrewing screws, a socket and a wrench for fastening volts and nuts, a wrapping tool for wrapping said wrapping wire on a pin of wrapping socket, and wire stripper or nipper for stripping said wrapping-wire's sheath.

Thus, for carrying a communication line setting work out, workers have to carry said multiple different tools with him in his tool belt or tool box and workers have to choose a suitable tool for each task he wishes to accomplish.

Since the conventional way has to set multiple different tools in a tool box or into a tool belt, it has several draw-backs of the difficulty of the selecting of the adequate tools swiftly and exactly in accordance with frequent changing the necessity. Especially with regard to the method of providing tools in a tool box, the user can't select adequate tools with ease and swiftness and with regard to the method of providing tools into a tool belt, the user can't replace the very used tool into said tool belt with ease and swiftness and the weighted tool belt makes the user's movement inconvenient.

And even though workers has to use the stripper for stripping said wrapping wire's sheath, until now usual workers generally have stripped the sheath of the wrapping wire by using nipper or cutting pliers in an informal way, however if the workers carry out their task with these informal tools in the communication line setting work, there will be a serious problem of cutting several strands of core wire of the wrapping wire unconsciously, furthermore even though if there were a communication trouble caused by this, it is not easy to find out the chief cause.

DISCLOSURE OF THE INVENTION It is an object of the present invention to solve above said problems of conventional tools.

This prevent invention provides an easy interchangeable communication line setting work hand tools by installing multiple communication line setting work hand tool components for example, drive bits, wrapping tool, socket and wire stripper etc. , into or on main body of this hand tool and this prevent invention also provides the convenience of the carrying tools and working of stripping the sheath of said wire without cutting several strands of core wire by installing wire stripper on the body of the prevent invention. Consequently the present invention is a communication ling setting work hand tool set, which contributes to the enhancement of the rate of completion of the communication line setting work.

BEST MODE FOR CARRYING OUT THE INVENTION The organization, working and effect of the present invention will now be described in detail with reference to the accompanying drawing as follows.

Fig. 1 is an exploded general perspective view of the present invention, Fig. 2 is a partial perspective view of the entrance part of the handle of the present invention, Fig. 3 is a general side cross sectional view of the present invention and Fig. 4 is an exemplary view of a state of using as a wire stripper of the prevent invention. The present invention consists of a main body (8) of this device with an installed clip (7) on it, a driver bit (1) and a wrapping tool (2) being stored in the cavity of the handle of the present invention.

The main body (8), a handle of this device shaped as a circular cylinder is formed with several inner cylinders (3) in which the driver bit (l) and the wrapping tool (2) are stored and the entrance of the main body can be opened and closed alternatively by a screw-type cap (14) ; a polygonal cavity (l 1) formed for setting the driver bit (1) at the front entrance part of the main body with a ball plunger (10) ; a polygonal socket (9); a wire stripper (13) with several V-type knife edges; a round shaped hole (5) penetrating the main body (8) vertically;

and a polygonal shaped hole (6) bigger than the round shaped hole (5).

At the middle part of the driver bit (l) and the wrapping tool (2), each polygonal shift part (17) is formed as the counterpart of the polygonal cavity (ll) of the main body (8) of this prevent invention.

Among the Figs, No 15, which has ho explanation, is wrapping wire used for setting work of communication line and No 16 is a tip formed at the both ends of the driver bit.

As stated above, since the present invention, a set of hand tool for a communication line setting work, is devised for storing several necessary communication line setting work hand tool components in a small bulk, workers can use said components of this hand tool selectively and interchangeably. Followings are detailed explanation.

In the communication line setting work, such as telephone line setting work etc. , the worker use the wrapping socket and the wrapping wire (15). And the necessary hand tools are limited in several kinds, such as the socket (9), the driver bit (l), the wrapping tool (2) and the wire stripper (13) because all the tool components for above said works are a certain standardized goods. The present invention provides all the above said tools in or on the main body (8) of this tool contemporary. (See Fig. 3) That is to say, when the worker don't use all the above-said hand tools, he can store all these tool components into the inner cavities (3) formed in the main body (8) and shut the entrance with the screw-type cap (14). Then the present invention, a set of hand tool, become as small as the main body (8) of this tool. Consequently the user can carry and keep the present invention with ease.

The user can get a necessary hand tool component such as the driver bit (1) or the wrapping tool (2) selectively out of the main body (8) by opening the screw-type cap (14) situated at the rear end part of the main body (8) and use the very hand tool component by inserting into the polygonal cavity (l 1) formed in the front part of the main body (8). The user can carry the communication line setting work without rotating phenomenon in using the driver bit (l) or the wrapping tool (2) since the polygonal shift part (17) is held by the polygonal cavity (l 1).

Then, when the user want to fasten or unfasten a screw he can use the driver bit (1) and when the user want to work of wrapping wire he can use the wrapping tool (2).

As the need arises, the user can select a (+) type tip or a (-) type tip (16) selectively, and insert the not selected tip (16) part into the polygonal cavity (11). And there is the ball plunger (10) installed in the inner part of the polygonal cavity (l l), and this will press the

inserted driver bit (1) not to be taken off easily.

When the user want to wind the wrapping wire (l5) at the around of the pin or unwind it from the pin of the socket (9), he can use the wrapping tool (2) by inserting this into the polygonal cavity (11) with using a end tip selectively as the need arises to the winding or unwinding function.

In case that the user work with the driver bit (l) or the wrapping tool (2) in narrow space, he can insert the driver bit (1) or the wrapping tool (2) selectively into the round shaped hole (5) penetrating the main body (8) of this tool perpendicularly. Then torque will be stronger by using this type combination. Since the polygonal shift part (17) is formed at the shift of the driver bit (1) and the wrapping tool (2) and the diameter of the polygonal shift part (17) is bigger than the diameter of the tip (16). Once the user insert the driver bit (l) or the wrapping tool (2) into the round shaped hole (5), the polygonal shaft part (17) is fitted to the polygonal shaped hole (6) and a raised step formed at the edge of the polygonal shaft part can't penetrate the round shaped hole (5). Consequently, the main body (8) of this invention joined with the driver bit (l) or the wrapping tool (2) in cross angle can get stronger torque than any other conventional hand tool. And the user can work with this in narrow space with ease. (See Fig. 3) The socket (9) formed at the front point of the polygonal cavity (ll) of the main body (8) is formed for fastening or unfastening a bolt or a nut excepting the screw.

For winding the wrapping wire (15) at the around of the pin of wrapping socket with the wrapping tool (2), to begin with, the user have to strip said wrapping-wire's sheath off.

The wire stripper (13) is formed for this role. The user insert the wrapping-wire (15) into the wire stripper (13)'s groove which is formed as V-type blade of knife to fit to the standardized wrapping-wire which is used for communication line setting work, and press down said wrapping-wire with his thumb. Then the sheath of the wrapping wire (15) get a scar by said groove. The user pull the main body (8) which is including the wire stripper (13) with pressing down said wrapping-wire with his thumb, then the sheath will be separated from said core wire of said wrapping-wire. Because the size of the groove of the V-type blade of a knife of the wire stripper (13) is standardized previously to the thickness of said wrapping- wire even if the user press down the wrapping-wire with his thumb he can make a scar just on the sheath of said wrapping wire without cutting of a strand of core wire of said wrapping wire. Consequently, the user can strip the sheath of the wrapping wire (15) with only his thumb's pressure.

Consequently the present invention has variety of functions and serves as multiple hand tools while utilizing only the small space and the user can carry the prevent invention by pinning the clip (7) stuck on the main body (8) at a working clothes with ease.

INDUSTRIAL APPLICATION As above-mentioned, by the combining multiple necessary hand tool components in a set, there is a improvement of the portability and handiness. And the user can carry out a communication line setting work in narrow place. Consequently the prevent invention contribute to improving the rate of completion of communication line setting work.
