Quick release mechanism for tools such as socket wrenches |
摘要 |
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 defines a sliding surface oriented transversely to the pin to engage an upper end of the pin. A first spring biases the sliding surface toward the pin, and a second, weaker spring biases the pin toward the sliding surface. Movement of the actuating member along the longitudinal axis of the drive stud in a selected direction allows the second spring to slide the pin from the engaging to the release positions.
