Abstract
An adjustable ratchet head assembly has first and second jaw members that are connected using a pinion shaft and a cogwheel shaft. The pinion shaft has oppositely threaded end portions that engage oppositely threaded pinion shaft receiving bores in a central section of each jaw member. The cogwheel shaft has oppositely threaded end portions that engage oppositely threaded cogwheel shaft receiving bores in a proximate end of each jaw member. A pinion gear is concentric with and engages the pinion shaft. A cogwheel gear is concentric with and engages the cogwheel shaft, and is in driving engagement with the pinion gear. Driving the cogwheel gear will cause rotation of the cogwheel shaft, pinion gear and pinion shaft, and will cause the jaw members to move toward or away from each other. The ratchet head assembly is received in a cylindrical ratchet head body, which is received in a handle assembly.
