Meanwhile, the rotation preventing structure 120 guides the sliding of the sliding sleeve 300, thereby facilitating the smooth sliding of the sliding sleeve 300 along the center positioning member 100. It should be noted that, one specific form of the anti-rotation structure 120 is: the center positioning member 100 is provided with a sliding groove, and the sliding groove is arranged along the length direction of the center positioning member 100, and the inner wall of the sliding sleeve 300 is provided with a protrusion extending into the sliding groove, so that the sliding sleeve 300 is prevented from rotating by restricting the protrusion in the transverse direction (the circumferential direction of the center positioning member 100) of the sliding groove.
