Description

  The present invention relates to a cuticle cutter called a cuticle nipper.

  Conventionally, there was no dedicated instrument for cuticle cutting, and it was replaced by nail clippers and nippers that existed in the past.

For example, the prior art related, applications from Brazil according to Patent Kohyo 2003-501192 (see Patent Document 1) Although Ru seen, this technical compatibility with the present invention are none.

Special table 2003-501192

  Therefore, an object of the present invention is to provide a dedicated cuticle cutter for nail beauty that cuts the cuticle around the nail beautifully.

The present invention is a container having a gently curved side surface from the tip of the blade body to the end of the handle body, and both the blade tip portions of the blade body are bent in one direction and sharpened at the tip portion, Both gripping parts of the handle are semicircular in cross section, and the pivot part is located slightly above the center of the crossing part at the crossing part of both gripping parts of the handle and both cutting edge parts of the blade, When one side surface portion of both gripping portions of the handle is grounded, both the blade tip portion and the crossing portion including the tip portion of the blade body are all lifted, and when the other side surface portion of both grip portions of the handle body is grounded, The opposite surface of the crossover portion of both blade tips is grounded, but the two blade tips including the tip part float up, and the expansion ammunition is accommodated in a pipe member provided at a position close to the pivot part of one gripping part of the handle In addition, the outer end of the presser that is in contact with the inner end of the extension ammunition protrudes from the tube member, and the pivot part of the other gripping part of the handle The groove provided on the relative position of proximity to the push rod, but made such that contact and separation of the pusher into the groove.

Since the present invention is composed of the above-described constituent means, it is possible to provide a device exclusively for cutting the cuticle that can be formed around the nail.

First, the grip the two sets of grip parts of the handle body cut work cuticles, by the pivot portion slightly is positioned above the center of the intersection, the fulcrum of the opening and closing movement of the proximity perilla double-edged tip portion since the opening degree is decreased, it is possible to perform reliably and quickly by light momentum.

Secondly, the entire body from the blade body to the end of the handle body has a curved line with a gentle side surface , and the blade edges of the blade body can be cut even when the gripping portion of the handle body is grounded at any of the upper and lower side surfaces. Since the portion is in a floating state, the sharp tip of the blade tip portion is not soiled or damaged, and can always be used with confidence.

Thirdly, the stretcher that opens and closes the handle is housed in a tube member provided on one gripping portion of the handle, which is in contact with the inner end of the presser and faces the presser. Since it is made to contact / separate the concave groove provided in the other holding part, failure such as detachment or loss of the ammunition does not occur during use, and a smooth cuticle cutting operation can always be performed.

Since the opening / closing operation of both gripping parts is smoothly performed within a short distance by the short expansion / contraction action of the expansion ammunition inside the pusher, there is no fatigue on the fingers.

When the instrument user now grasps both grip portion of the handle body, which from that in the position gently wrapped and pivot unit inside the palm portion is close to the double-edged tip portion of the upper side of the center of the intersection, nail while looking good cuticles portion around by operating the two sets of grip parts little by little, so that sure is really cut by the cutting edges that are open small and sharp.

When one side surface part of both gripping parts of the handle is grounded, both the blade edge part and the crossing part of the blade body are all lifted, and when the other side part of both gripping parts of the handle body is grounded, Although the opposite surface of the crossover portion of the two blade tips is grounded, the two blade tips are floated.

  The entire device is formed into a gently curved side surface from the tip of the blade to the end of the handle.

  Reference numeral 1 denotes a blade body. Both blade edge portions 2 and 2 of the blade body are bent in one direction, and tip portions 2 'and 2' thereof are sharp.

3 is a pattern member, two sets of grip portions 4 of the handle body Ri formed in cross-section, semi-circular, gripping gently ing by the palm.

Reference numerals 5 and 5 denote intersections between the gripping portions 4 and 4 of the handle 3 and the blade edges 2 and 2 of the blade body 1, and the pivot 6 provided at the intersection having a certain length is crossed. somewhat that is located above the center of the part.

When one side surface portion of both gripping portions 4 and 4 of the handle 3 is grounded, both the blade tips 2 and 2 and the crossing portions 5 and 5 of the blade 1 are all lifted (see FIG. 3). When the other side surface portions of the gripping portions 4 and 4 are grounded, the opposite surfaces of the intersecting portions of the two blade tip portions of the blade body are grounded, but the two blade tip portions are floating (see FIG. 4).

7 is a tubular member which is provided on the inner side of a position close to the pivot portion 6 of one of the grip portion 4 of the handle body 3, inside of the tube member to accommodate the expansion bullets machine 8.

9 is a pushing element in contact with inner end to the expansion bullets machine 8 in the pipe member 7, the inner end of the pushing element is made so as not detached from the pipe member 7.

An outer end portion of the push rod 9 is made so as to contact and separation toward the concave groove 10 provided in the other of the grip portion 4 opposing handle body 3. (Figures 2 and 5 ← → Figures 6 and 7)

Claims (1)

In a vessel that has a gently curved side from the tip of the blade to the end of the handle, both blade tips of the blade are bent in one direction and the tips are sharpened. The gripping portion has a semicircular cross section, and the pivot portion is provided slightly above the center of the crossover portion at the intersection of the gripping portions of the handle and the blade tips of the blade . When one side surface of both gripping parts is grounded, both the blade edge part and the crossing part including the tip part of the blade body are all lifted, and when the other side surface part of both gripping parts of the handle is grounded, While the opposite surface of the crossing portion is grounded, both the blade tip portions including the tip portion are levitated, and the expansion ammunition is accommodated in a pipe member provided in a position close to the pivot portion of one gripping portion of the handle body. The outer end of the pusher with its inner end in contact with the extension ammunition protrudes from the tube member and is close to the pivot of the other gripping part of the handle The groove provided on the relative position of the serial pushing element, cuticles cutting device, characterized by comprising as to contact and separation of the pusher into the groove.
