Meanwhile, a housing 1b is provided with a rotational axis 7 to be joined to the housing 1a, an electric power switch 11, and a battery box 12. The electric wiring 6 provided in the motor 5 is connected to an electric power switch 11 and a battery box 12, and the housing 1a and the housing 1b are joined and structured by fastening an attachment screw 9 fitted into a rotary shaft 7 and provided in a knob 8, into a nut 10 provided in the housing 1b.

Description

The present invention relates to an apparatus intended to shorten an elongated nail by shaving with a file instead of cutting with a conventional nail clipper or the like.

Conventionally, nails that have been extended have been generally cut or scraped with nippers, scissors, files, etc., using the lever principle.

The above-mentioned nail clippers are still widely used, but it is difficult to say that these nail clippers can be handled safely by anyone regardless of age or gender, especially for the elderly and children. It was not easy to use. In addition, the type in which the file of the disk is rotated by a motor and the tip of the toe is shaved has a drawback that it is difficult to scrape until the edges of both sides of the nail.

Means to solve the problem

The present invention does not cut the extended nail, but files the inside of the cone-shaped opening from the top edge to the bottom, rotates the structure with a motor, inserts the nail into the rotating structure, and makes contact The nail can be shaved by letting it go, but the special feature of the present invention is that the structure for shaving the nail is conical, so that the nail inserted into the conical structure is conical. It can be fixed firmly by contacting the filed part inside the conical structure with the two left and right points instead of the whole nail, and it can be moved regardless of the size of the nail by moving the rotating structure to the left or right. Yes, and it can be sharpened to the edges of both nails. Theoretically, the nail contacts the conical inner file with the outside and inside of the nail at a slight angle, so the outer peripheral tip of the nail is not vertical but slightly slanted, so no burr occurs. Since the conical structure part that cuts the surface and the other parts can be bent freely, the bending angle can be freely selected according to the usage conditions and individual conditions of the user, etc. Have.

Further, in the cylindrical shape according to the first aspect, the basic usability is excellent in the conical shape, but it is possible to obtain substantially the same effect as the conical shape.

Effect of the invention

It is possible to subtly adjust the sharpness of the nail and the hairline on both sides of the nail, and anyone can handle it safely regardless of gender.

Most of the components are covered with a housing that also serves as a grip, and the overall size is small enough to fit in the palm of the hand for easy handling.

It is a longitudinal cross-sectional view which shows the structure of the whole nail sharpener of this invention. It is a longitudinal cross-sectional view which shows the state which bent the nail sharpener structure part of this invention. It is a rear view which shows the state which carried out the partial cross section of the back surface of the nail sharpener of this invention. It is a right view which shows the bending range of the nail sharpener structure part of this invention. It is a fragmentary sectional view which shows the Example which set the nail | claw vertically to the nail sharpener of this invention. It is a fragmentary sectional view which shows the Example which rotates the nail | claw sharpener of this invention to the left centering on a nail | claw, and cuts a nail | claw. It is a fragmentary sectional view which shows the Example which rotates the nail | claw sharpener of this invention to the right centering on a nail | claw, and cuts a nail | claw.

In the nail sharpener of the present invention, since the structure file portion for cutting the nail has a conical shape, the nail in contact with the general structure file portion is not at the entire nail, but at approximately two points on the left and right sides. By touching it, it is firmly fixed, and it is possible to safely perform nail shaving around the entire nail.

An embodiment of the nail sharpener of the present invention will be described with reference to FIGS.
Inside the housing 1a, the bearing 4 having the file portion 2 formed in a conical shape on the material 3 on which the file portion 2 can be formed and the bearing 4 formed on the lower portion is directly connected to the motor 5, and the motor 5 is connected to the drive wiring. 6 and the series of mechanisms are incorporated in the housing 1a.

On the other hand, the housing 1b is formed with a rotating shaft 7 for uniting with the housing 1a, provided with a power switch 11 and a battery box 12, and a wiring 6 coupled to the motor 5 is connected to the power switch 11 and the battery box 12. The housing 1a and the housing 1b are connected to each other, and the housing 1a and the housing 1b are coupled and united by being fastened to a nut 10 provided on the housing 1b by a mounting screw 9 fitted on the rotary shaft 7 and provided on the knob 8. The battery 13 is set in the battery box 12 provided in the housing 1b, the battery cover 14 is closed, and the nail sharpener is in the working state.

For claw shaving, the knob 8 of the mounting screw 9 to which the housing 1a and the housing 1b are coupled is turned and loosened, the housing 1a is adjusted to an easy-to-use position, and then the knob 8 is tightened and fixed, and the housing 1b is held as a grip. Shake while touching the file part 2 and rotating left and right.
