Abstract

A friction grip normally preventing axial motion of a rod 12 with respect to a housing sleeve 14 that surrounds the rod includes a coil spring 30 whose diameter is slightly less than the diameter of the rod so that the coil spring normally encircles and grips the rod tightly. The coil spring is mounted on the rod between a bushing 26 fixed to the housing sleeve at one end of the spring and a second bushing 24 that is rotatable by means of lever 16 to relax the grip. Both bushings include bevelled faces 38, 39 which cause the last few turns at one end or the other of the spring to become aligned at an angle to the spring axis when axial movement of the rod is attempted, thus providing enhanced grip. <IMAGE>
