Abstract
The ratchet mechanism has a body which is secured to the tool's handle, and an output shaft which extends axially from the distal end of the body. The output shaft has a splined portion which is secured rotatably within a generally cylindrical axial cavity in the distal end of the body. Two pins are mounted to project through the body of the mechanism, on a rocker for example. Depending on the position of the rocker, one or the other or both of the pins extend(s) into the splines. The pins are configured such that one permits rotation of the splined portion in one direction and prevents rotation in the opposite direction, and the other pin permits rotation in the opposite direction and prevents rotation in the first direction. There are thus three operating positions, namely 'left', 'right' and 'locked'.
