Abstract
A tool clamping mechanism connects a first member to a second member. The first member has a cylindrical stem with a coupling tooth projecting from the stem. The second member has a clamping cavity formed by the union of a gripping bore and an access hole. The access hole has an access bore and a tooth access hole formed to accommodate the stem and the coupling tooth respectively. The stem diameter of the stem is larger than the gripping bore diameter of the gripping bore. The clamping cavity further has a coupling recess for accommodating the coupling tooth. The coupling recess has a drive surface for engaging a driven surface located on the coupling tooth to create a force which pushes the stem from the access bore into the gripping bore and helps prevent separation of the two members.
