Description

Nail Clipper {Nail clipper}

The present invention relates to a nail clipper. More specifically, the present invention is to have a curved shape of the upper curved cutting blade and the lower curved cutting blade in a dual shape of the blade curved portion and the straight line portion so that the shape of the cutting blade is easy to separate and cut nails growing in an arc shape. The present invention relates to a nail clipper that is formed similar to a real nail and configured to easily trim a nail.

In general, the nail clipper, as shown in Figure 1, the upper steel plate 11 and the lower steel plate 12 is formed in a shape in which one end is joined to each other, the other end is opened, the upper steel plate 11 and An upper straight cutting blade 16 and a lower straight cutting blade 18 are formed in each of the upper steel sheet shearing portion 15 and the lower steel sheet shearing portion 17 of the lower steel sheet 12, and the upper steel sheet 11 and the lower portion. The steel plate 12 has a hole in which the pressing bar 13 penetrates and is fixed to the upper steel sheet shearing portion 15 and the lower steel sheet shearing portion 17, and the lower portion of the pressing bar 13 has the lower portion thereof. It is fixed to the lower steel sheet front end portion 17 of the steel plate 12, the upper end portion is fixed to penetrate the upper steel sheet front end portion 15 of the upper steel plate 11 to be exposed thereon. A hole is formed at an upper end of the pressure bar 13, and is configured to rotatably fix the operation handle 14 to be interviewed with the upper steel plate 11. In addition, the operation handle 14 is formed so that the lever projection 19, which serves as a lever, to interview the upper surface of the upper steel plate (11). The operation principle by the configuration as described above is a common nail clipper can be easily understood by those skilled in the art as well as ordinary users. That is, the operation handle 14 is operated so that the lever projection 19 is interviewed on the upper steel plate 11, and the upper steel plate 11 and the lower steel sheet which are elastically coupled to each other by pressing. 12 is interlocked, and thus the upper straight cutting blade 16 and the lower straight cutting blade 18 formed at one end of each of the upper steel plate 11 and the lower steel plate 12 are operated to the nail 22. You can trim the Such nail clippers are manufactured and sold by leading domestic and foreign manufacturers, and anyone can easily purchase and use them. However, in the conventional nail clipper, as shown in FIG. 2, the cutting blade which actually cuts the nail 22 is formed in a straight line, and as shown in FIG. 3, it is only curved in the front-back direction. . When the curved shape of the cutting blade in the front and rear direction is viewed from above the nail 22, one nail 22 has a curved shape so as to protrude from the edge toward the center, thereby easily making the nail 22 easy. It has a curved shape in the front-rear direction so that it can be trimmed.

However, when the nail 22 is examined in detail, the nail 22 has a curved arc shape in which a portion to be grown and cut is curved, but the nail 22 also has a nail curved portion 24 and a nail straight portion as shown in FIG. 4. It is common to have 25, and the cutting part 23, which is mainly a part to be cut, has a smooth nail (22) when the nail curved portion 24 and a very small portion of the nail straight portion 25 are exposed.

There may be a problem that the nail 22 of the portion which is not cut due to the blade of the nail clipper is damaged. In addition, if the corner portion of the nail 22 is not accurately cut, the corner portion of the nail 22 may be cut less than other portions, and the less cut portion may protrude sharply and may damage the skin. have.

Therefore, in order to trim the nail 22 with an existing nail clipper, the cutting operation must be repeated several times, and accordingly, there is an inconvenience in that the nail 22 is cut a few times. In addition, when the nail 22 is cut several times a little, the cut surface is not evenly formed, and if you want to smooth it smoothly and evenly, there may be a case that the nail 22 has to be polished more deeply than originally intended. Excessive cutting of the nail 22 may be accompanied by pain due to severe exposure of the end of the finger 21 to the pain beneath the nail 22, and in severe cases, the nail 22 may be deformed enough to penetrate the skin and be operated. As a result, problems may need to be eliminated.

An object of the present invention is to shape the cutting blade to include the upper curved cutting blade and the lower curved cutting blade having a blade curved portion and the straight portion to make the nail easier to cut according to the nail curved portion and the nail straight portion of the actual nail. It is to provide a nail clipper that can be configured to trim.
