ABSTRACT:
A shaft drive includes a push button locking mechanism for releasingly locking the shaft drive to the attachment cavity of an attached tool. The locking mechanism can be used to positively couple one tool, such as a wrench drive, to another tool, such as a drive socket. A push button includes an inner end having a concave surface that interacts with the convex surface of a sliding locking bolt inside the shaft such that depression of the button moves the locking bolt to a release position. A spring in the locking bolt bore biases the bolt in its locking position.
