A plurality of movable rods 4 extending along the radial direction are arranged circumferentially on the fixed cylinder 6. A support ring 5 is fixedly connected to the outer end of the movable rod 4. An arc-shaped block 12 is fixedly connected to the inner end of the movable rod 4. The inner end of the arc-shaped block 12 is provided with an inverted sliding cone groove. After a plurality of the arc-shaped blocks 12 are connected end to end circumferentially, a cylindrical structure is formed, and a plurality of the inverted sliding cone grooves are spliced to form a conical hole 31 with an outer diameter larger than the inner diameter. The inner end of the first cylinder shaft 10 is provided with a conical push head 32 that cooperates with the conical hole 31. A spring 13 is sleeved on the movable rod 4 between the fixed cylinder 6 and the arc-shaped block 12.
