[0038] The outer casing 1 is fitted with a silicone sleeve 7 at the operating end. The silicone sleeve 7 forms an annular groove on its inner side wall. A magnetic ring 8 is provided in the annular groove. When the silicone sleeve 7 is fitted onto the operating end of the outer casing 1, the magnetic force generated by the magnetic ring 8 is used to attract the outer casing 1 to prevent the silicone sleeve 7 from sliding axially on the outer casing 1. The outer casing 1 is made of a metal material that can be attracted by the magnetic ring 8, such as iron.

[0039] Multiple flat surfaces are provided on the outer circumferential surface of the silicone sleeve 7. The flat surfaces are distributed along the circumference of the silicone sleeve 7. Compared with the arc-shaped outer circumferential surface, the flat surfaces on the silicone sleeve 7 fit against the surface of the object on which the electric foot grinder is placed when it is placed horizontally, so as to prevent the electric foot grinder from rolling.

[0040] A hanging ear 9 is also provided on the outer peripheral surface of the silicone sleeve 7, through which the electric foot grinder can be hung; in this embodiment, the hanging ear 9 includes a connecting section 901 and a bending section 902. One end of the connecting section 901 is connected to the outer peripheral surface of the silicone sleeve 7, and the other end of the connecting section 901 is bent and extended to form the bending section 902. A hanging space is formed between the bending section 902 and the outer peripheral surface of the silicone sleeve 7.

[0041] The second end cover 3 is provided with two bolt through holes 10, which are arranged around the second through hole 6.

The cylindrical segment and the circular plate segment are provided with interconnecting shaft holes, and the shaft holes have a flat inner surface. In this embodiment, the driving component is a DC motor 13, and the rotating shaft of the DC motor 13 has a flat outer surface. When the rotating shaft of the DC motor 13 is tightly inserted into the shaft hole on the connector 11, the flat inner surface of the shaft hole is in contact with the flat outer surface of the rotating shaft of the DC motor 13, so that when the rotating shaft of the DC motor 13 rotates, it drives the connector 11 to rotate.

[0043] The grinding head 12 has a truncated cone structure and is made of an elastic material, such as silicone. One axial end of the grinding head 12 is the connecting end, and the other axial end is the grinding foot end. The diameter of the grinding head 12 gradually increases from the connecting end to the grinding foot end. A connecting post 14 is provided at the connecting end, and a mating hole is provided on the connecting post 14. The grinding head 12 is connected to the shaft of the DC motor 13 by the mating of the connecting post 14 and the connecting head 11.
