[0027] A limit plate 11 is fixedly mounted on the top of the connecting pipe 9 , and a second spring 12 is sleeved on the surface of the connecting pipe 9 and located at the bottom of the limit plate 11 .

[0028] Reference Figure 5 The limiting plate 11 and the second spring 12 cooperate with the first spring 8 and the abutment plate 6 to ensure that the circular abutment block 7 is in contact with the surface of the eccentric block 203, while avoiding the disadvantage that the first spring 8 fails and the entire device cannot work.
