[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] The embodiment of the utility model discloses a novel tooth polisher.

[0024] Example 1

[0025] Reference Figure 1-3 A new type of tooth polisher includes a handle 1 and a polishing cup 5. A rotating rod 4 is rotatably provided on one side of the upper end of the handle 1. The rotating rod 4 is rotatably connected to the outer wall of the handle 1 through a sealed bearing to improve the sealing between the rotating rod 4 and the handle 1. The polishing cup 5 is fixedly arranged on the end of the handle 1 where the rotating rod 4 is away from the handle 1. A first cavity is opened at the upper end of the handle 1, and a rotating sleeve 2 is rotatably provided on the outer wall of the lower end of the handle 1. The rotating sleeve 2 is a rubber sleeve with good anti-slip performance. A plurality of finger sleeves 3 are fixedly provided on one side of the rotating sleeve 2, and a second cavity is opened inside one side of the upper end of the rotating sleeve 2.

[0026] Example 2

[0027] A transmission mechanism for driving the rotating rod 4 to rotate is provided inside the first cavity. The transmission mechanism includes a first bevel gear 6 and a second bevel gear 8. The first bevel gear 6 is fixedly sleeved on one end of the rotating rod 4 located in the first cavity, and the second bevel gear 8 is meshed and arranged on the lower side of the first bevel gear 6. A motor 7 is fixedly provided at the bottom end of the cavity, and the output end of the motor 7 is fixedly connected to the middle part of the lower side of the second bevel gear 8.

[0028] Example 3

[0029] The interior of the second cavity is provided with a limiting mechanism for limiting the rotation of the rotating sleeve 2 relative to the handle 1. The limiting mechanism includes a tooth column 12 and a spur gear 13. A stopper 9 is slidingly provided inside the second cavity. A connecting rod 11 is fixedly provided on the upper side of the stopper 9. The upper end of the connecting rod 11 extends to the outside of the second cavity. The tooth column 12 is fixedly provided on the upper end of the connecting rod 11. The spur gear 13 is fixedly sleeved on the middle end of the handle 1. The tooth column 12 is meshed with the spur gear 13. The cross-sections of the stopper 9 and the second cavity are both rectangular. A spring 10 is fixedly provided on the lower side of the stopper 9. The other end of the spring 10 is fixedly connected to the inner wall of the cavity to facilitate the resetting of the stopper 9.

[0030] In the present invention, when in use, the palm of the hand holds the rotating sleeve 2, and the fingers pass through the finger sleeve 3, so that the polisher can be held stably, which can improve the stability of the teeth polishing operation and make the teeth polishing process more stable and safe. When it is necessary to adjust the polishing angle, the tooth column 12 is pressed to separate the tooth column 12 from the spur gear 13, which can release the limit between the rotating sleeve 2 and the handle 1, and the handle 1 can be rotated relative to the rotating sleeve 2, so that the direction of the polishing cup 5 can be adjusted, which is convenient for teeth polishing at different angles.

[0031] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
