  The present invention relates to a nail clipper used for trimming fingernails or toenails, and a nail clipper cover used by attaching to the nail clipper, and more particularly, positioning of a nail with respect to a cutting edge of a cutting blade. The present invention relates to a nail cutter and a nail cutter cover provided with an additional structure that can facilitate the above.

  Caring for the fingers or toenails, in particular, cutting the nails short, is a necessary appearance in daily life. As a nail cutter used for such nail trimming, a nail cutter provided with a pair of upper and lower blade plates and a push plate has been widely used.

  The upper and lower blade plates are made of a metal material rich in elasticity, such as spring steel, and are connected integrally by overlapping the base end portions, and the cutting blades facing each other at the tip portions separated by a suitable length in the thickness direction. I have. The push plate is pivotally supported at the tip of a support shaft penetrating and held near the tip of the upper and lower blade plates so as to be swingable about an axis substantially perpendicular to the support shaft. The lever is abutted against the outer surface of the blade plate, and a “lever” is constructed with the pivotal support portion as a fulcrum and the abutment portion of the push piece as a power point.

  The nail cutter configured in this manner is used by inserting fingernails of fingers and toes between the cutting blades at the top and bottom of the upper and lower blade plates, and pressing the tip of the push plate toward the blade plate. As a result, one blade plate pressed by the pressing piece of the pressing plate approaches the other blade plate, the cutting blades at the tip of both blade plates are brought into contact with each other, and the nail inserted between these cutting blades is cut. Is done.

In recent years, various proposals have been made to improve the usability of this type of nail clipper, and a cover for covering the upper and lower blade plates from both sides in the width direction is provided to prevent scattering of the cut nail. A nail-cutting tool (see, for example, Patent Document 1), and a force point member that contacts the upper surface of the blade plate pressed by the pressing plate at a plurality of locations, thereby reducing the bending deformation of the blade plate A nail cutter (see, for example, Patent Document 2) that attempts to make a good contact with the cutting blade, and a ball joint is used for the connecting portion between the support shaft and the push plate, so that it can be used and not used. There is a nail cutter (for example, see Patent Document 3) that facilitates changing the position of the push plate.

  The nail clippers disclosed in the above-mentioned Patent Documents 1, 2, and 3 can achieve the usability improvement effect described in each of them, but no consideration is given to safety, which is the most important problem.

  That is, the conventional nail clipper using the nail clipper is performed by inserting a fingernail or fingernail between the upper and lower blades, as described above. It is necessary to match the relationship with the scale. This alignment can be performed without any problems for adults and healthy people, but it is difficult for elderly people, children, and physically disabled people, and the push plate is operated without being correctly aligned. There is a risk that fingers and toes may be accidentally injured by the abutting cutting blades.

  In recent years, it may be required to cut the toe with an appropriate length for post-processing such as manicure and pedicure. In such a case, the conventional nail clipper requires a desired cutting edge. In order to obtain the length, there was a problem that it was forced to be aligned multiple times and was unusable.
