When the second rod 403 is stressed to act on the sliding surface, the second rod 403 does not exert force on the ratchet wheel, and the ratchet wheel does not rotate; when the second rod 403 is forced to act on the stop surface, the second rod 403 pushes the ratchet wheel to rotate.
The rotating wheel is arranged between the second ratchet wheel 302 and the fourth ratchet wheel 304 and comprises a wheel disc 501, an axle 502 and gear teeth 503 arranged along the wheel disc, and the gear teeth 503 are in gear contact with the second ratchet wheel 302 and the fourth ratchet wheel 304; the second 302 gear teeth of the ratchet wheel, the fourth 304 gear teeth of the ratchet wheel and the gear teeth of the rotating wheel are all one-way teeth and comprise a stopping surface for the gear teeth and a sliding surface opposite to the stopping surface, and the sliding surface is an arc-shaped surface, so that the matching resistance can be reduced.
