ABSTRACT:
A ratchet-based, torque-enhanced fastener tool for tightening and loosening nuts, bolts, lug nuts and other fasteners includes a main housing and a handle attached to the main housing. A trigger is movably connected so that it can be moved in a reciprocal manner. A drive mechanism in the main housing is connected to the handle such that reciprocal movement of the handle moves the drive mechanism. A ratchet gear is functionally connected to the drive mechanism so as to rotate when the drive mechanism is moved. A drive gear is connected to the ratchet gear so as to rotate when the ratchet gear is so rotated. A socket wrench driver is connected to the drive gear so as to rotate simultaneously with the drive gear. By this arrangement, a user may attach a nut socket to the socket wrench driver, hold the handle and squeeze and release the trigger repeatedly to rotate the nut socket to drive a nut or other fastener.
