A tool clamping mechanism (10) connects a first member (12) to a second member (14). The first member (12) has a cylindrical stem (20) with a coupling tooth (28) projecting from the stem (20). The second member (14) has a clamping cavity (50) formed by the union of a gripping bore (54) and an access hole (52). The access hole (52) has an access bore (62) and a tooth access hole (64) formed to accommodate the stem (20) and the coupling tooth (28) respectively. The stem diameter (D3) of the stem (20) is larger than the gripping bore (D2) diameter of the gripping bore (54). The clamping cavity (50) further has a coupling recess (66) for accommodating the coupling tooth (28). The coupling recess (66) has a drive surface (68) for engaging a driven surface (38) located on the coupling tooth (28) to create a force which pushes the stem (20) from the access bore (62) into the gripping bore (54) and helps prevent separation of the two members (12, 14). |
