Abstract

A tool of the type having a drive stud for receiving and releasing a tool attachment includes an opening in the drive stud and a locking pin movably mounted in the opening. The opening defines upper and lower ends, and the lower end of the opening is located at a portion of the drive stud constructed for insertion into the tool attachment. The lower end of the locking pin is constructed to engage the tool attachment when the locking pin is positioned in an engaging position and to release the tool attachment when the locking pin is moved to a release position. An actuating element is movably positioned on the drive stud, and the actuating element is coupled to the locking pin to move the locking pin from the engaging to the release position as the actuating element moves along the longitudinal axis. An anti-rotation key is positioned between the actuating element and the drive stud to slide in a groove formed in either the actuating element or the drive stud and thereby to limit rotation of the actuating element and associated side loading of the locking pin. If desired, a resilient retaining element can be positioned in a recess in either the actuating element or the drive stud to limit movement of the actuating element relative to the drive stud along the longitudinal axis.
