[0031] The driving member 35 is disposed on the operating shaft 21 and can rotate with the operating shaft 21. The driving member 35 is protrudingly provided with a driving portion 351, and the driving portion 351 can abut against the pushing portion 36. When the operating shaft 21 drives the driving member 35 to rotate counterclockwise, the driving portion 351 pushes the locking rod 32 downward through the pushing portion 36; when the operating shaft 21 drives the driving member 35 to rotate clockwise, the driving portion 351 can be separated from the pushing portion 36, or the driving force of the driving portion 351 to drive the pushing portion 36 to move downward disappears.

[0032] The elastic member 33 is preferably a spring bar, which is sleeved on the outer side of the middle part of the locking rod 32, and the spring bar elastically abuts between the lower support plate 312 and the pushing portion 36, so that the locking rod 32 has the potential energy to move upward. When the driving portion 351 is separated from the pushing portion 36 or the driving force of the driving portion 351 on the pushing portion 36 disappears, the elastic member 33 can drive the pushing portion 36 and the locking rod 32 to move upward.

[0033] The limiting wheel 34 is connected to the lower part of the locking rod 32. The limiting wheel 34 includes a central axis portion 341 and two side wing portions 342, wherein the central axis portion 341 is connected between the two side wing portions 342, and the outer diameter of the central axis portion 341 is smaller than the outer diameter of the side wing portions 342.
