The intermediate housing 2 is a spherical housing and can rotate relative to the main housing 1, that is, the angle between the grinding wheel 31 and the main housing can be adjusted. There is no need for the user to adjust the angle of the wrist to make the grinding wheel 31 fit the skin, thereby increasing the user experience.

[0040] The foot grinder provided by the utility model is rotatably installed in the intermediate shell 2 by means of the rotating shaft 4. The intermediate shell 2 is clamped with the grinding wheel assembly 3. The intermediate shell 2 can rotate relative to the main shell. When the intermediate shell 2 reaches the required rotation angle, the grinding wheel assembly 3 is driven to move in an arc along the rotating axis of the intermediate shell 2, thereby adjusting the angle between the grinding wheel 31 and the main shell. Through the meshing of the bevel gears, the transmission connection from the second bevel gear to the third bevel gear can be maintained after adjusting the angle of the grinding wheel assembly relative to the main shell, so that the user can make the grinding wheel 31 fit the skin without adjusting the wrist angle, thereby increasing the user experience.
