ABSTRACT:
A powered adjustable jaw wrench comprises a wrench body having a handle portion and a head portion defining a stationary jaw, a movable jaw reciprocally mounted to the head portion, a driven mechanism operably connected to the movable jaw, and a drive mechanism mounted to the body member and including a power source and an indexing mechanism. The driven mechanism includes a worm driving the movable jaw and an indexing wheel operably connected to the worm gear. The indexing mechanism is driven by the power source and includes an oscillating pallet member. The pallet member incrementally drives the indexing wheel so as to convert an oscillating movement of the pallet member into an incremental rotatable movement of the indexing wheel.
