  However, in the cuticle cutter of the above-mentioned Patent Document 1, the blade itself, which is a part for cutting the cuticle, is linear. Therefore, there is no problem when cutting around the center of the cuticle, but when cutting the cuticle on both sides of the cuticle (near the area connecting from the base of the nail to the side of the nail), this straight blade will cut the cuticle well May not be caught. That is, it is difficult to cut the cuticle along the nail line (particularly the curved portion). Further, since the entire blade is linear, the front end portion of the blade is a sharp protrusion that is viewed from the side, and the front end portion may damage the nails and skin.

  An object of this invention is to provide the cuticle cutting tool which can cut | disconnect the whole cuticle easily along the line of a nail | claw, and also can cut a cuticle without damaging a nail | claw.

In order to achieve the above object, in the invention of claim 1, a blade formed forward and inclined in the front-rear direction, a grip portion formed rearward, and between the blade and the grip portion A long shaft including the formed connecting portion, and a rotating shaft for rotatably supporting the pair of structures at the connecting portion, and biasing the pair of the structures in a separating direction. A pair of the blades are brought into contact with each other by bringing the pair of gripping portions close to each other, and the cuticle is cut by sandwiching the cuticle with the blades, when the pair of blades are in contact with each other A convex curved part for cutting off the cuticle near the nail base to the side of the nail and a straight part for cutting off the cuticle near the center of the nail base , and A curved portion is formed continuously with the straight portion; Further, the angle formed between the tangent line of the straight part and the tangent line of the end point of the curved part is formed at a right angle or an acute angle when the pair of blades are viewed from the side. Provide a cutting tool. In short, a blade is formed at one end and two long bodies having the other end side as a gripping portion intersect each other between the blade and the gripping portion and pivotally support each other to approach the gripping portion. Then, the two blades come into contact with each other and cut the cuticle, and the blade line formed by the contact between the two blades is a portion near the nail base to the nail side. Ri straight portion for cutting the convex curved portion and the claw base portions cuticle near the center for cutting cuticles is Sonawa and the edge of the blade with the curved portion is formed continuously with the straight portion The cuticle cutting tool, which is formed and further has an angle formed by a tangent line of the straight line portion and a tangent line of the end point of the curved portion when the blade is viewed from the side, being a right angle or an acute angle .

  The invention of claim 3 is characterized in that the curved portion is formed at a front edge of the blade.

  The invention according to claim 4 is characterized in that the curved portion is formed at a rear edge of the blade.

  The invention of claim 5 is characterized in that the bending portion has a plurality of bending portions having different curvatures.

  According to invention of Claim 1 or 2, since a blade has a linear part and a convex curved part, according to the part of a cuticle, a linear part and a curved part can be switched suitably and can be used. That is, when cutting the cuticle near the center of the nail base, which is relatively straight, the cuticle can be cut quickly and easily using the straight portion of the blade. On the other hand, when cutting off the cuticle near the base connected from the base of the nail to the side of the nail, the cuticle can be easily cut off from the root by using a curved portion curved in a convex shape.

  According to invention of Claim 3, since the curved part is formed in the front-end edge of a blade, it can prevent damaging a nail | claw with the front-end edge of a blade, and handleability improves.

  According to invention of Claim 4, since the curved part is formed in the rear-end edge of a blade, the cuticle can be cut | disconnected using a rear-end edge, and it can apply to various cutting methods. Moreover, it can prevent that a nail | claw is damaged with the rear-end edge of a blade, and handling property improves.

  According to the invention of claim 5, since a plurality of curved portions having different curvatures are provided in the bending portion, it is possible to cut the cuticle at an optimum portion among the curved portions having different curvatures. Therefore, the cuticle can be cut without damaging the skin or the nails according to the shape of the nail line of the user.

It is a top view of the cuticle cutting tool which concerns on this invention. It is a side view of the cuticle cutting tool which concerns on this invention. It is a schematic side view which shows the 1st Example of a blade. It is a schematic side view which shows the 2nd Example of a blade. Ru schematic side view showing a third embodiment of the blade.

  As shown in FIGS. 1 and 2, a cuticle cutting tool 1 according to the present invention is connected so that a long structure 2 intersects with a rotation shaft 3. A blade 4 is formed in the front-rear direction in front of the structure 2. A grip 5 is formed behind the structure 2. A connecting portion 6 is formed between the blade 4 and the gripping portion 5, and the pair of structures 2 are connected to each other by the rotating shaft 3 described above at the connecting portion 6. The structure 2 is substantially linear in a side view. The connecting portion 6 is about half the thickness of the gripping portion 5, so that even if the connecting portion 6 overlaps, the gripping portions 6 in the structures 2 overlap each other in a side view.

  An elastic member 7 is provided between the pair of grip portions 5. The elastic member 7 is, for example, a leaf spring, and is attached so as to mesh the tips of the leaf springs and urge the gripping portions 5 outward (separating direction) in the drawing. Any member such as a spring may be used as the elastic member 7 as long as it is urged outward. The elastic member 7 may be provided on the side of the structure 2 where the blade 4 is provided with respect to the rotating shaft 3.

  When cutting the cuticle, the user holds the pair of gripping portions 5 and positions the cuticle between the pair of blades 4. And a pair of holding part 5 is moved to the direction which adjoins by gripping a pair of holding part 5 against the elastic member 7. FIG. At this time, the pair of blades 4 on the opposite side via the rotating shaft 3 are also close to each other. Then, the pair of blades 4 are in contact with each other and cut by sandwiching the cuticle. More specifically, the sharp tip that becomes the blade line of the blade 4 is cut by sandwiching the cuticle. Since this cutting process is substantially the same as the cutting by the nipper, the cuticle cutting tool 1 according to the present invention can be said to be a nipper type.

  As shown in FIG. 3, the blade 4 has a straight portion 8 and a convex curved portion 9 when the blade line is viewed from the side. In FIG. 3, a curved portion 9 is formed at the front edge of the blade 4. Thus, by providing the curved part 9 in a part of the blade 4, the cuticle can be cut along the line of the nail (cuticle) using the curved part 9, and the handleability is improved. Further, by forming the curved portion 9 at the front end edge of the blade 4 as shown in FIG. 3, the front end edge of the blade 4 does not become an acute angle. improves. In particular, when cutting the cuticle of the lower corner of the nail, the presence of the curved portion 9 can prevent the nail or the surrounding skin from being damaged.

  Moreover, as shown in FIG. 4, you may provide the curved part 9 in the rear-end edge of the blade 4 further. Thus, by providing a plurality of curved portions (two in FIG. 4), the cuticle can be efficiently cut regardless of which curved portion 9 is used. In addition, the cuticle can be cut using the rear edge of the blade 4 and can be applied to various cutting methods. In addition, although the example which provided the curved part 9 in the front-and-rear both-ends edge of the blade 4 was shown in FIG. 4, you may provide the curved part 9 only in a rear-end edge. Other structures and effects are the same as in the example of FIG.

  Further, as shown in FIG. 5, a plurality of curved portions 10 having different curvatures may be provided in the bending portion 9 (in FIG. 5, two curved portions 10a and 10b). FIG. 5 shows an example in which the curvature of the curved portion 10a is larger than the curvature of the curved portion 10b. By providing the curved portions 10a and 10b having different curvatures in one continuous bending portion 9, the cuticle can be cut at the optimal portion of the curved portions 10a and 10b having different curvatures. Accordingly, the cuticle can be cut according to the shape of the nail line of the user, and the skin and nails can be prevented from being damaged at that time. In addition, when the curved part 9 is provided in the front-and-rear both-ends edge of the blade 4 like FIG. 4 mentioned above, even if it makes the curvature of each curved part 9 different, the same effect can be acquired. Other structures and effects are the same as in the example of FIG.
