Description

The present invention relates to tweezers such as tweezers and tweezers, and particularly relates to tweezers which are tweezers that can be used to easily remove thin, short and small stabs such as waste hair and tweezers at positions that are difficult to remove. ..

Generally, when pulling out the unshaved beard that remains on the chin or nape after shaving, or small thorns stuck in fingers or the like, tweezers or tweezers are used as a pinch. In the present invention, these tweezers, tweezers, tweezers, and other tweezers are collectively referred to as "pinching tools".

These sandwiches are used not only for the purpose of pulling out thorns, waste hair, etc. as described above, but also for sandwiching various small, fine and thin objects. That is, in the present invention, the object to be pinched or pulled out is not limited to thorns or waste hair, and all the jigs for pinching these small, fine and thin objects are described as the concept of the pinching tool according to the present invention. ..

It is difficult to pinch and pinch various small, fine and thin objects such as the above-mentioned thorns and waste hair using a jig. Generally, a jig having a tip portion divided in two directions is used, so to speak, tweezers / tweezers, which is a form in which those small, fine and thin objects are sandwiched and pulled out between the tip portions. However, when it is difficult to see the objects to be pinched and pulled out and they are too small, it is often difficult to accurately confirm their positions, pinch and pull out. In order to solve these problems, various proposals have been made by the prior documents listed below.

For example, in Patent Document 1, a pair of tweezers arms facing each other are sandwiched between fingers to close the tips of these tweezers arms, and the tweezers body is attached between the tips of the tweezer arms and the tips of the tweezers. A tweezers-type waste hair remover composed of a coil spring that is compressed when a portion is closed. One plane is formed, and a second plane orthogonal to the first plane is formed on the outer surface thereof. When the coil spring is compressed, the first planes of the coil portions are brought into close contact with each other, and the tweezers are brought into close contact with each other. The entire second plane forms a continuous contact surface, and a spring retaining groove is formed at the outer end of each tweezers arm, and both outer ends of the coil spring are formed in the spring retaining groove. A technical idea regarding tweezers-type waste hair removal, which is characterized by locking a coil portion located at, is disclosed.

However, in this example, since the tip portion for sandwiching and holding the waste hair or the like is formed from the coil spring, the end surface thereof becomes an arc shape, for example, the surface in contact with the skin becomes a straight line. , It is difficult to see the waste hair that is the object to be pinched and pulled out, and if it is too small, it is difficult to accurately confirm their positions and pinch and pull out. In other words, it does not provide a fundamental solution to the conventional problem.

Further, Patent Document 2 also discloses the same technical idea, and provides a fundamental solution to the conventional problem that it is difficult to accurately confirm the position of minute waste hair that is difficult to see and to pinch and remove it. It is not supposed to be presented.

Japanese Patent No. 6231710 JP-A-2018-149243

In addition, for example, in the sheet metal cutting and sheet metal processing industries, in the processing of fine metal cutting chips and metal debris, fine metal powder sticks into the hands and feet, and it is very difficult to remove the fine metal powder. It has been desired to develop a sandwiching tool for easily sandwiching and extracting these fine metal powders (a type of thorn).

The present invention is intended to solve such problems in the prior art, and can be easily grasped even if the position of an object represented by a difficult-to-see minute thorn or waste hair cannot be accurately confirmed. Its task and purpose is to provide a pinch tool that can be pulled out and that is economically inexpensive while significantly improving safety and workability.

In order to solve such a problem, the pinch tool according to the present invention is a pinch tool provided with a pinch portion in which upper end faces of a plurality of thin flat plate-shaped portions are aligned in a constant manner and overlapped in a plane shape at a constant interval. Therefore, the object is sandwiched and gripped by any of the upper end faces of the flat plate-shaped portion of the sandwiching portion.

Further, in the sandwiching tool according to the present invention, in addition to the sandwiching portion, both ends of the plane near the lower part of the sandwiching portion are fixedly gripped, and both ends of the plane near the upper part of the sandwiching portion are sandwiched from the outside to the inside. It is also characterized by having a grip portion capable of pressure-welding the upper end surface of the flat plate-shaped portion.

That is, as shown in FIG. 1, the pinching tool according to the present invention can easily pinch and pull out waste hair and thorns between the tips of a plurality of thin flat plate-shaped portions. No matter where the waste hair or thorns are located between the plurality of thin flat plates, the waste hair or thorns can be sandwiched. Unlike the tweezers-shaped scissors, the range and area of the upper end of multiple thin flat plates are increased, so that the position of a thin, short and fine object can be grasped in a wide range, and one of the thin flat plates can be grasped in a wide range. It can be pulled out by sandwiching it between the upper ends.

The thin flat plate-shaped portion of the pinching portion of the pinching tool according to the present invention has a rectangular flat surface, one corner of the upper tip is a gentle arc shape, and the vicinity of the other corner is straight. You can also take.

As a result, the tip of the pinch tool according to the present invention can be gently brought into contact with human skin, and waste hair and thorns can be reliably pinched and pulled out.

Further, it is also possible to take a form in which a spacer portion for maintaining a constant distance is provided between the lower portion of each of the sandwiched portions of the sandwiching tool according to the present invention, which is the thin flat plate-shaped portion.

This makes it possible to keep the distance between the tips of the thin flat plate-shaped portions forming the sandwiched portions constant.

Both ends of the plane near the lower part of the sandwiching tool according to the present invention may be provided with a connecting and fixing portion for connecting and fixing to the gripping portion.

That is, by for example, screwing and integrating the gripping portion and the sandwiching portion via the connecting and fixing portion, the gripping portion has a shape like tweezers, and is easy to operate by hand and easy to use. Therefore, the usage method is the same as, for example, the conventional tweezers type hair removal or thorn removal.

In addition, the thin flat plate-shaped portion of the sandwiching portion of the pinching tool according to the present invention is an embodiment in which the upper end portion or the lower end portion is formed by connecting with the front and rear thin flat plate-shaped portions, respectively. You can also take it. (See Fig. 3)

As described above, the thin flat plate-shaped portions forming the sandwiching tool according to the present invention do not necessarily have to be individual flat plate-shaped portions one by one. It may be a connecting body as shown in FIG. It suffices that the ends of each thin flat plate portion are formed at regular intervals. Any aspect may be used as long as it is possible to grasp the position of a thin, short, and fine object in a wide range, sandwich it between the upper ends of each of the thin flat plates, and pull it out.

The size and material of the sandwiching tool according to the present invention are not limited, but any material may be used as long as it can be handled in the same manner as conventional tweezers, tongs, and the like. That is, it may be a constant hard material and may be a material having a slight bend, and can be manufactured with a material such as stainless steel. Further, the size and shape can be arbitrarily adjusted depending on the object to be gripped. In other words, it is also possible for industrial use.

As described above, the sandwiching tool according to the present invention is not limited to the above-described embodiment, and can be variously modified and implemented within a range that does not deviate from the gist of the present invention. All of these, including the doctrine of equivalents, claim to be part of this technical idea.

According to the present invention, a pinch tool that can be easily grasped and pulled out even if the position of an object such as a minute thorn or waste hair that is difficult to see cannot be confirmed accurately is realized. In addition, according to the present invention, it is possible to provide a pinch tool that is economically inexpensive while significantly improving safety and workability.
