ABSTRACT:
The mechanism, used in a ratchet wrench, includes a body carrying an integral stud. A bore extends axially into both and an actuator rod is reciprocally mounted therein. A transverse bore in the stud slidably holds a pin which is linked to the rod. A socket is applied to the mechanism by pushing the socket against a camming surface on the pin to enable the socket to be snapped onto the pin without operating the actuator. The socket is removed by depressing the actuator.
