At the tip of No. 2, the upper and lower cutting edges 53, 54 with a predetermined angle
Are formed parallel to each other. The support pin 55 is inserted through the upper and lower blades, and the upper blade 5 of the support pin is inserted.
A pressing operation lever 56 is rotatably supported at the upper end on one side.

With the base end portion and the upper cutting edge 53 as fulcrums, a concentrated load is received from the power point portion 58 of the lever portion 57. And
Since the point of force is located in the middle of each fulcrum, the upper blade 5
There was a problem that 1 was bowed. When the upper blade body 51 bends in a bow shape, there is a problem that the upper blade edge 53 is inclined outward by the deflection angle at the point A. When the nail is cut in this state, the upper and lower cutting edges 5
As a result, there arises a problem that burrs are generated on the cut surface of the nail and the nail cannot be cut cleanly.

A nail clipper for widening the width of the plate 1 may be considered. However, in these nail clippers, when the upper and lower blade edges 53 and 54 are engaged with each other, the elastic force of the upper blade body is increased when the plate thickness is large. Then, it ’s difficult to handle,
There is a problem that the nail clipper becomes large.

The cover 21 covering both sides of the holding plates 2 and 13 is
It is formed so as to be continuous with 0. A concave portion 21a is formed substantially in the center of the front end portion of the cover portion 21 on both the upper and lower cutting edges 14a and 15a in the longitudinal direction. The pressing plate 20 and the cover portion 21 are bent by, for example, press working or the like so as to have a U-shape in a normal cross section.

１力点となる力点部２８ａである。On the upper surface side of the holding plate 20, a pressing operation lever 26 as a pressing lever member is rotatably supported on the support pin 18 by a shaft pin 27 penetrated through the shaft hole 19. On the upper surface of the distal end portion of the pressing operation lever 26, a lever portion 28 which is formed to protrude in a mountain shape is formed. The ridge line, which is the upper end of the leverage 28, is a power point portion 28 a serving as a first power point with respect to the holding plate 20.
【００２１】そして、爪切り１１を使用する際には、図

When the pressing operation lever 26 is pressed, the shaft pin 2 is pressed.
7 serves as a fulcrum, and the pressing plate 20 is pressed by the power point portion 28a. For this reason, the pressing plate 20 applies a pressing force to the upper blade body 12 via the distal end surface 25a with the base end portion 20a as a fulcrum, and the upper blade body 12 uses the base end portion 12a as a fulcrum to set the elastic force of the upper blade body 12. Is pressed downwards. As a result, the upper and lower blade portions 14 and 15 approach to each other, and the upper and lower blade edges 14a and 15
The nail is cut by the contact of a.

ままで、下刃部１５に接近することになる。At this time, the holding plate 20 is formed so as to extend from the base end portion 12a of the upper blade body 12 to the front end portion, and the upper surfaces of the holding plate 20 and the upper blade body 12 are connected to the front end surface 25a of the pressing portion 25. And at the base end 20a. Therefore, when the upper blade tip 14a contacts the claw, the upper blade body 12 has the base end 12a of the upper blade body 12 and the upper blade tip 14a as fulcrums,
This means that a concentrated load is received from the distal end face 25a and the base end 20a of the holding plate 20. Since these force points are located almost directly above the fulcrums, the upper blade body 12 pressed by the pressing plate 20 does not bend like an arc. Therefore, the upper blade portion 14 and the upper blade edge 14a approach the lower blade portion 15 while maintaining the predetermined angle.

Presses the whole over the width direction. Therefore, the upper cutting edge 14
The pressing force is evenly applied to a in the width direction, and the claws are cut cleanly without generating burrs.

い。In this case, the pressing operation lever 25 is formed obliquely with respect to the upper blade tip 14a, and the pressing operation lever is compared with a case where the pressing portion 25 is in contact with the upper blade body 12 at only one point. There is no bias applied to one of the width directions. That is, since a uniform force is applied in the width direction of the pressing operation lever 26, the belly of the finger operating the pressing operation lever 26 is not hurt.

弓なりに撓むことをことなく爪を切ることができる。According to the above embodiment, the following features can be obtained. (1) In the above-described embodiment, since the distal end surface 25a of the pressing portion 25, which is the point of emphasis on the upper blade body 12, uniformly presses the distal end portion of the upper blade body 12 in the width direction. There is no need to increase the thickness, and the nail can be cut with a small force without bending the upper blade body 12 like an arc.

できる。(2) In the above embodiment, since the distal end surface 25a of the pressing portion 25 is formed parallel to the upper blade edge 14a and over the entire width direction, a pressing force is applied to the pressing plate 20. In this case, the distal end face 25a presses the entirety in the width direction. Therefore, the pressing force is evenly applied to the upper blade edge 14a in the width direction, and the nail can be cut cleanly.

撓むことをことなく爪を切ることができる。(3) In the above embodiment, the holding plate 20 is in contact with the upper blade body 12 at the distal end surface 25a and the base end portion 20a, and is located between the upper blade edge 14a of the upper blade body 12 and the base end portion 12a. Since the pressing force is not applied to the blade, the upper blade body 12 can cut the nail without bending more like an arch.
