Obviously, the first rotating shaft 221, the second rotating shaft 222 and the third rotating shaft 223 are driven by the motor 3 to rotate synchronously.

(17) Furthermore, in order to ensure the stability of the rotation of the first rotating shaft 221, the second rotating shaft 222 and the third rotating shaft 223, the outside of the insertion joints of the second rotating shaft 222 and the third rotating shaft 223 are equipped with buffer springs 23 to reduce the impact of vibration. Secondly, in order to further ensure the stability of the rotation of the third rotating shaft 223, the end of the third rotating shaft 223 located at the first through hole 11 is plugged and fixed with the polishing head. A plurality of collars 24 are sleeved on the outside of the third rotating shaft 223 located in the cavity, the outer portions of the plurality of collars 24 are engaged with the inner wall surface of the main shaft 21, thereby allowing the third rotating shaft 223 to rotate along a predetermined route in a stable environment.

(18) In the embodiment, referring to FIG. 3, furthermore, the number of collars 24 is two, and the two collars 24 are respectively located outside the third rotating shaft 223 near both ends. In fact, in other embodiments, the number of collars 24 can be three, four, etc., as long as the third rotating shaft 223 can be ensured to rotate on a predetermined route and its stable rotation speed can be ensured.

(19) In the embodiment, referring to FIG. 2 to FIG. 4, furthermore, the UV lamp assembly 4 comprises a TYPE-C board 41, a UV curing lamp 42, a tail cover 43 and assembly that meet the normal operation of the UV lamp assembly 4; the TYPE-C board 41 is mainly the interface for the current input of the power supply assembly 6; one side of the UV curing lamp 42 is disposed on the side of the TYPE-C board 41, and the other side faces the direction of the second through hole 12; the tail cover 43 is installed on the second through hole 12. It should be noted that the tail cover 43 can transmit the light emitted by the UV curing lamp 42, thereby curing the nail polish on the nails.

(20) Furthermore, further elaboration will be given on the shell 1 wrapping the above structure. Referring to FIG. 1 and FIG. 2, the shell 1 comprises an upper shell 131, a lower shell 132, a pen tip shell 14 and a decorative ring 15; the upper shell 131 and the lower shell 132 are snapped together to form a half shell 13; the half shell 13 has an open end; the pen tip shell 14 is sealed and assembled with the open end through the decorative ring 15, thereby forming the accommodation cavity. It should be noted that the end of the shell 1 is the second through hole 12, the end of the pen tip shell 14 is the first through hole 11, and the outside of the pen tip shell 14 is in the shape of a truncated cone. The inner diameter of one end of the pen tip shell 14 with the first through hole 11 is smaller than the inner diameter of the other end of the pen tip shell 14. This design facilitates nail polishing, that is, it facilitates the operator to control the process of operating the nail polisher on the nails.

(21) In essence, please refer to FIG. 1, FIG. 2 and FIG. 4, the outside of the half shell 13 is provided with a UV lamp switch 1311, a nail polishing switch 1312 and a USB socket. The UV lamp switch 1311 is used to turn on or off the UV curing lamp 42. As for the nail polishing switch 1312, a toggle switch is used to control the forward or reverse rotation of the main shaft 21. Pushing the nail polishing switch 1312 along the direction of the first through hole 11 causes the main shaft 21 to rotate forward, pushing along the direction of the second through hole 12 causes the main shaft 21 to rotate reversely, and when it is in the middle, it is in a closed state. Then the USB socket is used to charge the internal power supply assembly 6 externally.

(22) In the present embodiment, referring to FIG. 1 and FIG. 5, furthermore, the power supply assembly 6 is disposed on the side of the PCB board 5 for supplying energy to the internal structure of the shell 1. The power supply assembly 6 includes a battery module.

(23) A further description of the working principle of the nail polisher: first, the battery module supplies energy to the internal structure of the nail polisher. When work is required, the operator pushes the nail polishing switch 1312. The motor 3 drives the rotating shaft 22 to rotate, causing the polishing head connected with it to rotate accordingly to polish the nails. Secondly, when you want to adjust the rotation speed of the grinding head, you can adjust the stepless speed control component 7, that is, rotate the roller 71 that is rotated to drive the rotation of the potentiometer to control the output voltage of the PCB board 5, adjust the power of the motor 3, and then adjust the rotation speed of the rotating shaft 22 in the transmission mechanism 2. Thereby adjusting the rotation speed of the polishing head, polishing the nails in an optimal way to make the nail surface smooth and strengthen the adhesion. After applying nail polish to the nails, the nail polish needs to be dried, that is, the nail polish is cured. At this time, turn on the UV lamp switch 1311, and the UV curing lamp 42 will emit purple light to bake the nails in a small range, thereby quickly drying the nail polish. This design has a small baking range, and the UV curing lamp 42 focuses on the nail cap to avoid damage to the skin on the back of the hand, which greatly facilitates customers' manicure needs.

(24) Above are only preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modification, equivalent replacement and improvement made within spirit and principle of the present disclosure should be included in protection scope of the present disclosure.
