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. An actuating member is movably positioned on the drive stud, and the actuating member includes a blade that defines a sliding surface oriented transversely to the locking member to fit within a slot in the locking member and engage a ledge surface of the locking member. Movement of the actuating member along the longitudinal axis of the drive stud in a selected direction causes the ledge surface to slide along the sliding surface to move the locking member from an engaging to a release position.
