The first embodiment is as follows:

as shown in FIG. 1, the foot grinding device comprises a hand-held foot grinder 100 for grinding dead skin of the sole of a foot and a base 200 having a support plane which can be stably placed. The base 200 is used for placing and supporting the hand-held foot grinder 100.

The lower end of the hand-held foot grinder 100 is provided with a first foot grinder part 2. When the first foot part 2 is applied to the foot, the dead skin or the fingernail may be ground or cut off as the first foot part 2 contacts and rubs against the skin surface, or the fingernail.

As shown in fig. 2, the base 200 is composed of a bottom wall 201 having the above-described support plane and a peripheral side wall 202. The peripheral sidewall 202 extends from bottom to top around the outer edge of the bottom wall 201, so that the base 200 presents a three-dimensional shape, and a concave accommodating groove C is formed between the bottom wall 201 and the peripheral sidewall 202.

Furthermore, as shown in fig. 1-2, the hand-held foot grinder 100 is provided with a placing part, and the base 200 is provided with a supporting part; in the set state, the base 200 is disposed below the hand-held foot grinder 100, and the rest portion is placed on the support portion. The hand-held foot grinder 100 can stably stand on a floor, a table, or the like, which is in contact with a support plane, together with the base 200.

This facilitates use and storage of the hand-held foot sharpener 100. The user is at the mill foot in-process, if need suspend to use the mill foot ware, can conveniently shelve handheld mill foot ware 100 on base 200, avoids the first mill foot portion 2 contact of handheld mill foot ware 100 to put the platform, improves the sanitary degree that handheld mill foot ware 100 used, so also further improved the convenience of accomodating of mill foot ware moreover, be favorable to the user to get at any time and put the mill foot ware.

In the above placing state, the first grinding leg part 2 is accommodated in the accommodating groove C, and the first grinding leg part 2 and the inner surface of the bottom wall are spaced apart by a distance to form a dust collecting area for collecting the dust falling from the first grinding leg part 2. Thereby, remain and drop in this collection bits region because of the action of gravity at 2 upper leather scraps of first mill foot, the collection and the clearance of the further leather scraps of being convenient for.

Preferably, the support plane of the base 200 is provided with a friction structure that allows for foot grinding to form a second foot grinding portion. The base 200 can be used as a separate component to perform a foot or nail polishing function.

As shown in fig. 3, the bottom surface of the base 200 in this embodiment includes a mounting plane P, and the sheet-shaped grinding foot 300 may be adhered on the mounting plane P, wherein the sheet-shaped grinding foot 300 is one of sandpaper and pumice. The frictional structure having the grinding leg on the outer side surface of the sheet-like grinding leg member 300 forms the second grinding leg part 8. When in use, the outer side surface of the sheet-shaped grinding foot piece 300 is used as a supporting plane, so that the base 200 is stably placed on the placing platform.

Further preferably, the bottom surface of the base 200 is provided with an annular protrusion 9 surrounding the assembly plane P, and the annular protrusion 9 has an annular end surface M that is a plane. The inner periphery of the annular protrusion 9 and the fitting plane enclose a fitting recess for fitting the blade-shaped foot member 300, and the blade-shaped foot member 300 is selectively stuck in the fitting recess.

It will be appreciated that when the blade foot 300 is fitted in this mounting position, the outer side face of the blade foot 300 exceeds the annular end face M of the annular projection 9, the outer side face of the blade foot 300 serving as a support plane for the base 200. And the annular convex part 9 positions and blocks the sheet-shaped foot grinding piece 300 in the mounting position, so that the influence of the displacement of the sheet-shaped foot grinding piece 300 on the bonding strength of the sheet-shaped foot grinding piece 300 on the base 200 when the foot part is rubbed by the second foot grinding part 8 is avoided. And when the sheet-like foot member 300 is not fitted in the fitting position, the annular bottom surface of the annular projection 9 is used as a support plane for the base 200.

Preferably, the boss 20 and the step of the base 10 are transited by a first annular arc surface, and the upper end of the peripheral sidewall of the base 200 has a second annular arc surface matching with the first annular arc surface.

It is further preferred that the hand-held foot grinder 100 rests on the base 200. The lower edge of the base 10 is aligned with the upper edge of the base 200, and the base 10 is smoothly bordered by the outer surface of the base 200. Thus, the appearance of the whole foot grinding device is more concise and beautiful.

Preferably, as shown in fig. 1-2, the annular outer periphery of the boss 20 is provided with a first rib 6 extending along the circumferential direction, and the inner wall of the outer periphery of the base 200 is provided with a matching longitudinal first rib 7; when the hand-held foot grinder 100 is placed on the base 200 and a downward force is applied, the first protruding strip 6 is clamped at the lower section of the first protruding strip 7 after passing over the first protruding strip 7, so that the hand-held foot grinder 100 is inseparably clamped with the base 200 without external force.

It should be understood, of course, that when the hand-held foot sharpener 100 is merely rested on the base 200 in a resting motion without applying a downward force against the base 200, the first rib 6 is rested on the first rib 6 by the first rib 7 as a resting portion, the first rib 7 is as a support portion, and the hand-held foot sharpener 100 rests on the base 200 in a contacting manner. At this time, the user can lightly hold and place the hand-held foot grinder 100, so that the hand-held foot grinder 100 can be taken and placed more easily and conveniently.

It is to be noted that in the present embodiment, when the hand-held foot grinder 100 is placed with the first rib 6 as a placement portion and the first rib 7 as a support portion, a gap is provided between the lower edge of the base 10 of the hand-held foot grinder 100 and the upper edge of the base 200. When the hand-held foot grinder 100 is fastened to the base 200 by the engagement of the first ribs 7 and the first ribs 6, the lower edge of the base 10 is aligned with the upper edge of the base 200, and the base 10 is smoothly bordered by the outer surface of the base 200. Therefore, when the whole foot grinding device is used for grinding the foot, the hand feeling of the user holding the foot grinding device is more comfortable.

As shown in fig. 1, the outer surface of the lower edge of the base 10 is provided with a concave notch K, at least a part of the annular upper end surface 5 of the base 200 is exposed from the notch K, and the user applies an acting force to the annular upper end surface 5 of the base 200 at the notch K, so that the first protrusion 6 is separated from the limit of the first protrusion 7, and the hand-held foot grinder 100 and the base 200 are released from the engaged state and can be separated from each other.

Of course, there are alternative embodiments of the connection configuration between the hand-held foot sharpener 100 and the base 200 that can be used in place of the connection configuration of the first ribs 7 and the first ribs 6.
