[0030] The jacking rod 8 is fixed with the movable connector 13 at the front end, the rubber strip 9 is provided with a sliding groove, the movable connector 13 is connected in the sliding groove in the rubber strip 9, and the outer diameter of the movable connector 13 is equal to the width of the sliding groove, so that the jacking rod 8 and the rubber strip 9 can move relative to each other, and the jacking rod 8 can fully and stably attach to the detection surface of the ring by pressing the rubber strip 9.
