The output terminal of gear switch 1006 is connected to the third input terminal of the control circuit board. Pressing gear switch 1006 outputs different signals to the control circuit board, and the control circuit board adjusts the on / off and speed of motor 2002 based on the signals output by gear switch 1006. When the user presses shift switch 1006 for the first time, an on signal is sent to the control circuit board, which drives motor 202 to begin operation. The user presses it again, which sends a shift adjustment signal to the control circuit board. The control circuit board adjusts the speed by varying the voltage output to motor 202, and this cycle of shift adjustment continues. When the user holds shift switch 1006 for a specified period of time, an off signal is sent to the control circuit board, which shuts down motor 2002. The output terminal of steering switch 1007 is connected to the fourth input terminal of the control circuit board. Pressing steering switch 1007 sends a forward or reverse rotation signal to the control circuit board, which then adjusts the forward or reverse rotation of motor 2002 based on the signal from steering switch 1007. When the user presses the steering switch 1007 for the first time, a forward signal is output to the control circuit board, and the control circuit board drives the motor 2002 to rotate forward. When the user presses the steering switch 1007 again, a reverse signal is output to the control circuit board, and the control circuit board drives the motor 2002 to rotate reversely. This cycle can switch the forward and reverse rotation of the motor 2002. The output end of the sensor 2004 is connected to the fifth input end of the control circuit board. After the sensor 2004 senses that the nail grinder contacts the skin, it transmits a signal to the control circuit board, and the control circuit board turns off the motor 2002 to stop working.

[0046] In other embodiments (not shown in the figure), the control circuit board can also expand the output interface to power external devices, such as providing a 5V2A voltage output to provide power for a night light or a small fan, thereby improving the utilization rate of the nail grinder.

The same shape of the inner cavity 4001 and the main shell 1000 can not only make the entire storage device 4000 more beautiful, but also maximize the use of space and improve storage efficiency. At the same time, the consistency of the inner and outer shapes also helps to enhance the stability and durability of the overall structure, and can also make it more convenient for users to take out or put in the nail grinder. In addition, by providing the storage device 4000, the nail grinder can be protected from damage and prevented from being affected by dust and other pollutants when not in use. It is also convenient for users to carry.

[0048] In this embodiment, if Figure 13 As shown, the storage device 4000 also includes six storage holes 4002, and three protrusions 4003 are provided at the lower end of the storage holes 4002. The connecting part 3001 is passed through the storage holes 4002 and fixed by the protrusions 4003. The three protrusions 4003 can provide more stable support to prevent the connecting part 3001 from shaking or sliding in the storage device 4000. By passing the connecting part 3001 through the storage hole 4002, the space can be effectively utilized, making the storage device more compact.

[0049] In other embodiments (not shown in the figures), six receiving holes 4002 may be provided on the receiving device 4000 or configured in any other desired number. In other embodiments (not shown in the figures), four protrusions 4003 may be provided on the receiving hole 4002 or configured in any other desired number to provide stronger stability. In other embodiments (not shown in the figures), a magnetic attraction portion is provided on the inner cavity 4001 and the receiving hole 4002, and the main housing 1000 and the polishing component 3000 are stored in the inner cavity 4001 and the receiving hole 4002 by magnetic attraction.
