One side of the auxiliary block 103 is fitted with the support rod 102, and a mounting groove 104 is provided on one side of the top of the auxiliary block 103. The first shock-absorbing spring 105 is movably provided on the inner wall of the mounting groove 104.

[0023] In this embodiment, preferably, the shock absorbing mechanism includes a shock absorbing tube 200, a second shock absorbing spring 201, and a limit block 202. The second shock absorbing spring 201 is sleeved on the surface of the support rod 102, and the top side of the auxiliary block 103 is in contact with the bottom side of the second shock absorbing spring 201. The surface of the support rod 102 is sleeved with a shock absorbing tube 200, and a plurality of limit blocks 202 are arranged around the inner wall of the shock absorbing tube 200, and the limit blocks 202 are snap-fitted and connected with the second shock absorbing spring 201.

[0024] In this embodiment, preferably, one side of the bottom end of the shock absorbing tube 200 is in contact with the top end of the first shock absorbing spring 105 .

[0025] In this embodiment, preferably, the protective mechanism includes a force transmission plate 300, a rubber plate 301, a second fixed groove 302, a protective rod 303, a sliding groove 304, a third shock-absorbing spring 305, and a shock-absorbing block 306. The shock-absorbing tube 200 is fixedly provided with a force transmission plate 300 at the top, and the rubber plate 301 is fixedly provided at the top of the force transmission plate 300. The rubber plate 301 has a second fixed groove 302 at the top, and the second fixed groove 302 runs through the force transmission plate 300.

[0026] In this embodiment, preferably, the second fixed groove 302 is perpendicular to the first fixed groove 101 and is on the same horizontal line, and protective rods 303 are fixedly arranged on both sides of the bottom end of the force transmission plate 300, and the protective rods 303 are L-shaped.
