A clamp plate is secured to the base and a clamp lever is attached to the clamp plate. A latch is loosely secured to a pin attached to the clamp lever and connected to a spring to provide a plate clamping force upon the clamp plate. A guide plate and a plate release preventing plate are attached to an outer longitudinal side of the base. An axial displacement control device is positioned at one longitudinal end of the cylinder while a circumferential displacement control device is positioned at the other longitudinal end thereof.
