Description

[Detailed description of the invention] The present invention is an improvement on the blade of a known nail clipper, and its purpose is to cut the front end of the nail, which is in close contact with the fingertip surface, into a perfect shape. To obtain a nail clipper capable of cutting semicircularly.

First, we will discuss the deficiencies of conventional nail clippers.

In the conventional nail clipper, the blade plate portions 10 and 10' at the front ends of the two upper and lower blade bodies 1 and 2 are rectangular with both upper and lower ends when viewed from the front of the blade. The cutting edge 5 and 6 are designed to hold the nails in place for front cutting.

Therefore, there is no problem when cutting around the center of the nail (as shown in Fig. 3, 8'), but the human fingernail 8 is in close contact with the surface of the flesh 7 of the finger, as shown in the schematic diagram in Fig. 2. Both sides of the nail are marked 8/
Since it is curved as shown by / and B11, there is a drawback that sharp claws in the shape of symbols 9 and 9 remain at both ends of the claw 8.

The reason for this uncut portion will be explained below.

The blade plate part 10 of the conventional nail clipper has a mouth-shaped rectangular surface, and this surface comes into contact with the flesh part 11 of the finger 7, and in particular, the left and right curved parts 8'' of the nail, which have a three-dimensional structure, It was extremely difficult to insert the lower blade into the lower surface of the 8".

Therefore, as a result of the front cutting by inserting the nail halfway into the lower surface of the nail, sharp nails such as 9, 9 remain on the left and right sides.

However, these sharply shaped nails 9, 9 are dangerous as they can easily dig into the flesh of the fingers, causing damage to the fingers and causing bleeding, and making it easier for Vikings to infiltrate and disintegrate them. Met.

In order to eliminate the above-mentioned deficiencies, the proposed nail clipper has cuts 4, 4 made on both sides of the blade plate 10 with the cutting edge 5 at the front end of the lower blade 1 of the upper and lower blades. As shown in Fig. 4, the sharp lower blade 5 is placed on the lower surface of the uncut sharp parts 9, 9 of the nail.゜5' can be easily inserted, and by finger pressure of the lever 3, the drumstick-shaped lower blade 10,
4, 4, 5.5', 5'' and the upper blade 6, 10', this device has the great feature of being able to pre-cut the nail into a beautiful, perfectly arc-shaped nail. This nail clipper is particularly effective for pre-cutting thick, hard, horny nails like big toenails.
