When the first sliding part 3331 is again located in the second guide groove section 323, the first sliding part 3331 again moves in a direction away from the center of the gear 325 along the radial direction of the gear 325, because the stop collar 3352 fixes the positioning hook at the second right position, the first sliding block 33321 will move from the right side of the positioning hook groove to the highest point of the positioning hook groove under the action of the first sliding part 3331, and under the action of the elastic force of the compressed spring 3361, the positioning hook 3351 moves to the first position relative to the positioning hook groove and fixes the first sliding block 33321 at the first position. In other embodiments of the present invention, a hook is disposed between the first sliding portion 3331 and the first sliding block 33321, and the positioning hook 3351 is moved from the highest point of the positioning hook groove to a first position relative to the positioning hook groove by a pulling force of the hook.
