Abstract
A retaining and locking clamp, mounted onto a first apparatus, for retaining and locking a second apparatus to the first apparatus. The first apparatus has a plate which in turn includes an aperture. The clamp comprises an inner rod that has a first end portion and a second end portion, the second end portion being adapted to be received within the aperture of the first apparatus plate so as to mount the inner rod to the first apparatus. The clamp also includes an outer sleeve that is rotatably mounted onto the inner rod, the outer sleeve has a retaining and locking flange and a surface. The clamp further comprises a turn knob that is rotatably mounted onto the inner rod, the turn knob has a surface that is adapted to frictionally engage the outer sleeve surface, whereby rotating the turn knob causes the turn knob surface to frictionally engage the outer sleeve surface so as to permit the outer sleeve flange to retain the second apparatus. The continued rotation of the turn knob after the rotation of the outer sleeve flange causes the outer sleeve flange to translate in an axial direction so as to firmly lock the second apparatus to the first apparatus.
