The outer surface of the block 10 is movably connected to the inner surface of the limit groove 8, and a connecting rod 11 is fixedly installed between the block 10 and the sliding sleeve 5. The block 10 and the sliding sleeve 5 will drive the connecting rod 11 to slide synchronously during operation. One end of the connecting rod 11 is equidistantly provided with a strip groove 12, and a cylinder 13 is fixedly installed inside the strip groove 12. Both sides of the surface of the cylinder 13 are movably sleeved with a moving block 14, and a buffer spring 15 is fixedly installed between the moving block 14 and the strip groove 12.
