Abstract:
1. A hand tool having a body, and a chuck with an axial opening on an axis of said hand tool, where a tool element is movable by an actuation apparatus between a retracted position generally within the body, and an extended operative position wherein the tool element extends through the axial opening and chuck, characterized by said hand tool further having a post, the post being independent of the actuation apparatus, for blocking said tool element against retraction when in said operative position, said post being laterally flexible to a position where it no longer blocks said tool element when retraction is desired, wherein said post is a generally axial post positioned generally on said axis and wherein said actuation apparatus includes an actuation arm having an angled slot for displacing said axial post, retraction of said actuation arm causing said actuation arm to displace laterally by virtue of said angled slot which engages a pin on said tool element, said actuation arm positioned so as to contact said axial post when so displaced laterally, to displace said axial post away from said axis to permit retraction of said tool element.
