[0025] The top of the limit assembly 35 includes a connecting rod 351 and a limit spring 352. The top of the outer wall of the connecting rod 351 is rotatably interlaced with the connecting plate 33. The limit spring 352 is sleeved on the outer wall of the connecting rod 351. The limit spring 352 is used to give the connecting rod 351 a downward elastic force.
