Patent attributes
An assembly includes a body, a plunger, a biasing member and a set screw. The body has a top surface, a bottom surface, and a polygonal drive surface interposed between the top surface and the bottom surface. The body has a first passageway extending from the top to the bottom surface, a second passageway extending from the polygonal drive surface to the first passageway, and a third passageway extending from the polygonal drive surface to the first or second passageway. The plunger has a channel that defines an interior surface having a threaded portion. The plunger moves within the second passageway. The biasing member biases the plunger toward a first plunger position. The set screw is movable within the third passageway between a first position in which the set screw inhibits movement and a second position in which the set screw allows movement of the plunger within the second passageway.
