Abstract
There is disclosed an improved wrenching tool which utilizes readily removable key member that is axially restrained in a key holder of the tool member by a detent ball and that can be released from the tool by precisely aligning the key holder to the outer, rotationally driven socket member of the tool. This invention comprises a release mechanism to locate the key holder in the tool at the precise position where the detent ball is aligned with a ball cavity in the outer socket member, thus permitting lateral displacement of the detent ball, and releasing the central key member. Preferably the key release includes a knob on a shaft which extends through a sidewall of the tool housing and which internally supports a cam that is received in a cam guide on an axially sliding block which is secured in a subassembly to the key holder.
