Kind Code:

Abstract:
A reversible monkey wrench includes a handle (10), a head (20), a slidable jaw (30), an axial rod (40) and a worm gear (50). The handle (10) has a connecting end for the head (20) to abut thereagainst. The head (20) is formed with a fixed jaw (21), a sliding rail (22), a receiving slot (23) and a connecting bore (24). The connecting bore (24) communicates with the receiving slot (23). A movable pin (63) and a spring (62) are disposed between the connecting end (11) and the head (20). A top of the movable pin (63) selectively inserts through the connecting bore (24). The spring (62) urges the movable pin (63) so that the movable pin may abut against the connecting end (11). The worm gear (50) is adapted to control the slidable jaw (30) to move and is slidably disposed in the receiving slot (23) with respect to the axial rod (40). The movable pin (63) selectively abuts against the worm gear (50) to prohibit the worm gear from sliding.
