RATCHETING DRIVER

摘要

A ratcheting driver comprises a driving mechanism combined between a handle and a working end for translating rotary motion from the handle to the working end. A switch engages the driving mechanism to switch the rotational direction of the working end between clockwise rotation and counter-clockwise rotation with an optional locked position that locks the working end. Two pairs of cooperating pawls are provided that are selectively engaged by the switch with one pawl in each of the two pairs of cooperating pawls selectively engaging one of a first ratchet gear and a second ratchet gear. Each pawl in the pair of cooperating pawls are positioned axially apart from each other in alignment with one of the first ratchet gear and the second ratchet gear.

1. A ratcheting driver comprising:
a working end for acting on a work piece; a handle positioned apart from the working end; and a driving mechanism combined between the handle and the working end for translating a rotary motion from the handle to the working end; a reversing mechanism combined with the driving mechanism for providing unidirectional rotation of the working end in one of a clockwise and counter-clockwise direction; a first ratchet gear and a second ratchet gear combined with the reversing mechanism; and two pairs of cooperating pawls with each pawl in the pair of cooperating pawls positioned axially apart from each other to engage one of the first ratchet gear and the second ratchet gear to provide selective one-way rotation of the working end.
