The driving mechanism 26 includes: a motor 261, which is arranged on the outer wall of the inner frame 14 through a bottom plate; a rotating shaft 262, one end of which is fixedly connected to the output shaft of the motor 261; a second gear 263, which is fixedly connected to the other end of the rotating shaft 262; a rotating ring 264, which is rotatably connected to the inner wall of the inner frame 14; a rack 1 265, which is fixedly connected to the top of the rotating ring 264 and meshed with the second gear 263; a rack 266, which is fixedly connected to the bottom of the rotating ring 264 and meshed with the first gear 22.

[0049] Embodiment 2

[0050] See also Figure 1-5 , based on the first embodiment, an auxiliary function is added;

[0051] The buffer mechanism 24 includes: a frame 241, which is arranged at one end of the threaded frame 23 away from the gear 1 22; a telescopic rod 242, one end of which is fixedly connected to the inner wall of the frame 241 and the other end of which is fixedly connected to the fixed plate 25; and a spring 243, which is sleeved on the outside of the telescopic rod 242. The fixed plate 25 is arc-shaped, and a rubber pad 251 is arranged on the facing surface of the fixed plate 25. A gravity sensor 252 is arranged in the middle of the rubber pad 251, and the gravity sensor 252 is electrically connected to the motor 261.

[0052] The working principle of the buffer mechanism 24 is as follows: when the fixed plate 25 contacts the outer wall of the dial, the fixed plate 25 drives the telescopic rod 242 to move inside the frame 241, and compresses the spring 243 at the same time to buffer the pressure on the outer wall of the dial. When the fixed plate 25 is away from the dial, the spring 243 brings the fixed plate 25 and the telescopic rod 242 back to their original positions. The fixed plate 25 is arc-shaped, which increases the contact surface with the circular dial and increases the stability of the fixed plate 25 when it is fixed. When the fixed plate 25 contacts the dial, the rubber pad 251 protects the outer wall of the dial to prevent the fixed plate 25 from damaging the outer wall of the dial. When the fixed plate 25 gradually approaches the outer wall of the dial, the pressure on the gravity sensor 252 increases. When it increases to the critical pressure value set in advance, the gravity sensor 252 sends an electrical signal to the motor 261, and the motor 261 is turned off, and it is impossible to continue to link the fixed plate 25 to continue to apply pressure to the dial.
