  • Retaining means for impact drive socket
    Patent number: 4448564
    Abstract: An improved retainer for the locking pin of an impact drive socket features an axially-movable sleeve that surrounds the pin and retains the same. The sleeve may be advanced (or retracted) on the socket, against the bias of a spring, thereby uncovering the locking pin. The pin may be removed to facilitate removal of the impact socket from the drive shank of an impact wrench or other tool.
