[0034] The inner wall surface of the first sleeve 11 is connected to a first pawl 12 via a torsion spring, and the first pawl 12 is meshed with a first ratchet 13. The first ratchet 13 is fixedly sleeved on the surface of a drive shaft 14, and the drive shaft 14 is sequentially provided with a bearing passing through the top of the chassis 1 and the bottom of the first sleeve 11.
