During the movement, the volume in the volume chamber four 56 decreases, and the liquid in the volume chamber four 56 enters the space of the volume chamber two 48 through the connecting pipe four 55 for replenishment. At the same time, part of the liquid is squeezed through the connecting pipe five 57 into the moving ring 33, and further enters the conducting pipe through the upstream pipe 35. 36, the movable column 38 moves, and then the clamping piece 37 contacts the gear ring to be inspected for clamping.
