[0002] A nail grinder is a nail art tool. Existing nail grinders are generally divided into two types: one is plug-in type and the other is rechargeable;

[0003] The structure of common nail grinders is relatively simple. During use, the rotation of the motor will cause high-frequency collisions between the grinding head and the shell, thereby generating noise, reducing the user experience, and after long-term use, the looseness of the motor will cause the device to fail to work properly and reduce its service life. Therefore, we propose a silent structure for a nail grinder. Utility Model Content
