[0026] Specifically, torsional spring 26 is sleeved on the surface of movable rod 22, one end of torsional spring 26 is connected with flap 23, the other end of torsional spring 26 is connected with connecting plate 21, torsional spring 26 can reset the position of movable rod 22, to improve the use effect of the device.

[0027] As shown in the figure, Figures 1 to 4 Two flaps 23 are located on the two sides of drive wheel mechanism 12, to improve the locking effect of drive wheel mechanism 12.

[0028] Further, clamping button 24 is made of "wear-resistant material", to improve the wear resistance of clamping button 24, to avoid excessive wear of clamping button 24 during long-term use.

[0029] As shown in the figure, Figures 1 to 4As shown, the damper strip 27 is mounted on the surface of the flap 23 close to the locking disc 25, and the damper strip 27 is in close contact with the locking disc 25, which is used to increase the resistance between the flap 23 and the locking disc 25, so that the clamping button 24 is always clamped in the insertion hole on the surface of the locking disc 25, further improving the stability of the locking of the driving wheel mechanism 12.

[0030] As shown in the figure, Figures 1 to 4 The driving assembly 3 includes a gear 31, and the gear 31 is mounted on the surface of the movable rod 22.
