When piston 1 is moved to the left by the action of fluid delivered to the right end of its cylinder, tapered bushing 2, rigidly mounted on the piston rod, turns elastic levers 3 about fixed axes A. The levers actuate four plungers 4 which locate and clamp the workpiece. As the elastic levers are deformed, they compensate for variations in the sizes of the workpieces. The workpiece is released when piston 1 is moved to the right by spring 5.
