A hand held gear wrench for reaching inaccessible locations having a pivotal head (20) connected to a bifurcated handle (44). Rotation to sockets (72) or a shank (66) to which external sockets are attached is provided by the use of an external wrench attached to a shaft (58) that is journaled through a clamp (60) that is adjacent to and contiguous with the handle (44). A universal joint (56) is fixed to the shaft (58), on one end providing the angular movement, and also to a worm gear (38), on the other, transmitting the rotation 180 degrees to a gear wheel (36). The wheel has a shank (66) or a keyed opening (68) receiving various sockets that interface with a workpiece. A rod (52), threaded on one end and having a tip (54) of resilient material on the other, is positioned within the handle (44) and compressibly interfaces with an arm on the head (20) impeding the axial movement of the head in relation to the handle (44) controlling the resistance and angular placement of the head (20). |
