摘要

The pin has a clamping stop positioned at an end of a tapered rod (2) and comprising an outer abutment surface (60). A clamping lever (9) comprises a cam (28). A movable support unit (30) is interposed between a periphery of the cam and the abutment surface. The support unit comprises a locking surface (311) that is in contact with the cam and separated from the abutment surface by a distance (D1). The support unit comprises an unlocking surface that is in contact with the cam and separated from the abutment surface by another distance (L2) less than the former distance.
