The locking member is movable from a locking position to a release position, the damping compound is between the follower and a supporting surface, the driver is rotatably fixed relative to the shuttle and includes a camming surface. The driver biasing element is for forcing the driver from a first position to a second position when the locking member moves to the release position. |
