Description

  The present invention relates to daily necessities, and more particularly to a nail file tool, and in particular, to a nail file for preparing a nail in a convenient, quick and safe manner.

  Nail clippers or scissors were often used when preparing nails. Due to advances in science and technology, more and more people use electric nail files. The file of such an electric nail file adopts a grinding machine type, and prepares the nail by a polishing method. Grinding machines are usually manufactured with a small grinding wheel or abrasive metal sheet.When grinding, the grinding machine rotates at a high speed, which tends to cause nail shavings to scatter and burn the fingers. May occur. Further, the high temperature resulting from the polishing makes the feeling uncomfortable, the finishing effect is not ideal, and depends on the skill level of the user. Therefore, it is necessary to make various improvements to the nail file. Examining a Chinese patent database, for example, the following contents were disclosed in a patent document with a publication number CN102217830A and an invention name “automatic claw file”. In the automatic nail file, including a nail file, the nail file adopts a disk-shaped file, and includes a file tooth, a file body, the file tooth is installed around the file body, the automatic nail file further includes a file cap, An arch-shaped nail insertion slot is installed on the side of the file cap. Since the automatic nail file having such a structure has only one nail insertion opening, the nail insertion opening has a relatively folded size. However, for various users, for example, baby and physique Each person with a good finger size has a different finger size, and the baby's finger may completely enter the nail insertion slot, which may hurt the finger. I can't cut my nails. Even in the same person, the finger sizes are also different. For example, since the thumb is larger than the little finger, the thumb nail may not be cut. Therefore, the application range is limited.

  Due to the problems present in the background art, the technical problem to be solved by the present invention is to provide an automatic safety nail file that fits various size fingers and can be used safely.

  For this purpose, the present invention is realized by the following technical solutions. Automatic including a disk-shaped file, a file driving device, and a file cap, wherein the file driving device is connected to the disk-shaped file, a claw insertion port is installed in the file cap, and the claw insertion port corresponds to the disk-shaped file. In the safety nail file, a plurality of the nail insertion openings are installed on the circumference of the file cap, the sizes of the nail insertion openings are different, and an arch-shaped thin sheet protruding from the nail insertion opening is provided. And

  Another technical solution of the present invention includes a disk-shaped file, a file driving device, and a file cap, wherein the file driving device is connected to the disk-shaped file, and a claw insertion port is installed in the file cap. In the automatic safety nail file in which the nail insertion port corresponds to the disk-shaped file, a movable movable cap is installed on the file cap, and the nail insertion port is installed on the movable cap and protrudes from the nail insertion port. An arch-shaped thin sheet is provided, a movable movable cap is installed on the file cap, and the claw insertion opening is installed on the movable cap.

  A plurality of movable movable caps are installed around the file cap.

  The area of the nail insertion opening is provided with an arch-shaped recess that matches a finger.

  In such a structure of the present invention, by installing a plurality of nail insertion openings around the file cap, the user can select a different nail insertion opening depending on the size of the finger and prepare the nail. By installing a protruding arch-shaped thin sheet, it is possible to guard the finger muscles outside the nail insertion slot, so there is no damage to the finger when preparing the nail, it is safe, reliable and easy to use Is good and brings good use effect.

1 is a structural diagram of a first embodiment of the present invention. It is a structural view of the file cap of the present invention. It is sectional drawing which follows AA of FIG. 2 of this invention. FIG. 6 is a structural diagram of a second embodiment of the present invention. It is a structural exploded view of the third embodiment of the present invention.

  1, 2, and 3, such an automatic safety claw file includes a disk-shaped file 5, a file driving device, and a file cap 4, and the file driving device is coupled to the disk-shaped file 5. A claw insertion slot 1 is installed in the file cap 4, the claw insertion slot 1 corresponds to the disk-shaped file 5, and a plurality of the claw insertion slots 1 are installed around the circumference of the file cap 4. Since the size of the insertion slot 1 is different, an arch projecting from the nail insertion slot can be selected for a single user by selecting a suitable nail insertion slot 1 according to the size of his / her finger. In the projecting arch-shaped thin sheet 2, the roundness of the arch matches the roundness of the fingertip. Therefore, when the finger is put into the nail insertion slot 1, , Projecting arched thin sheet The nail is separated from the fingertip muscle, the muscle is guarded outside the nail insertion slot, the nail is inserted into the nail insertion slot 1, and the file drive device drives the disk-shaped file 5 to sharpen the nail. It is safe, reliable and does not hurt your fingers. The area of the nail insertion slot 1 is provided with an arch-shaped dent 3 that matches a finger, and the arch-shaped dent 3 matches the meat part of the fingertip and puts the finger into the nail insertion slot 1 when preparing the nail. The arch-shaped recess 3 fits the meat part of the fingertip, can comfortably arrange the nails, and has a sophisticated appearance.

  Referring to FIG. 4, the difference between the structure of this embodiment and the above-described embodiment is that a movable movable cap 8 is installed on the file cap 4, and the claw insertion opening 1 and the arch-shaped recess 3 are all movable. The other structure is the same as that of the above-described embodiment. When the movable cap 8 is installed on the file cap 4, it can be installed by a slide groove type. For example, the slide cap 6 is provided on the file cap 4, the left and right blade plates 7 are installed on the movable cap 8, and the left and right blade plates are installed. 7 can be attached and detached by engaging with the slide groove 6, and the exchange of the movable cap 8 becomes convenient. When the nail insertion slot 1 of the above embodiment is installed, the size of the nail insertion slot 1 is fixed, which may not be applicable to a person with a particularly large or small finger size. If 1 is installed in various specifications having various sizes, the movable cap 8 can be replaced to suit various users. Therefore, if a suitable one cannot be found from the claw insertion opening 1 provided in the file cap 4, the movable cap 8 of the file cap 4 may be replaced. The method for engaging the file cap 4 and the movable cap 8 is a slide groove, and of course, a locking method may be adopted. For example, there are various engagement methods such as installing an elastic hook on the movable cap and installing a recess matching the elastic hook on the file cap. These are well-known common senses, and detailed examples can be omitted in this embodiment.

  Referring to FIG. 5, the present embodiment is an improvement based on the second embodiment, and a plurality of movable caps 8 are installed around the file cap 4. The purpose of such a design is to effectively utilize the upper surface area of the movable cap 8 and provide a plurality of selectable nail insertion openings 1 in the same manner as in the first embodiment. The other structure is the same as that of the second embodiment.

  This structure of the present invention is very convenient to use because it is easy to use, has high safety, has a good finishing effect, and is suitable for various users.
