Description

Scissors for both hands}

The present invention relates to a pair of scissors, and in particular to a two-handed scissors that can be conveniently used as well as left-handed.

Conventional general scissors are inconvenient for left-handed use because they are made primarily for right-handed use. In recent years, left-handed scissors are being manufactured separately, but they are easier to obtain and more expensive than right-handed scissors. For this reason, having both a right-handed scissors and a left-handed scissors in a house is as difficult as a left-handed person using right-handed scissors.

Right-handed scissors and left-handed scissors have opposite blades. Explaining the difference based on a normal right-handed scissors, the scissors usually put the thumb in the small hole of the handle and the rest of the fingers in the big hole, while the right-handed scissors have the thumb outside. Located on the side. Therefore, when scissoring unconsciously the force is given to the outside facing the thumb, the blades are gathered, and when cutting things, the blades are naturally engaged and cut well.

On the other hand, in the case of using the right-handed scissors described above using the left hand, the blade to insert the thumb is located inside. Therefore, when you give force to cut things, the blades are opened by the principle of the lever, and the interlocking force is reduced, so that they are not cut well.

In addition, if you use the right-handed scissors with the right hand, you can cut the object while checking the interlocking position of the blade with your eyes, but you can use the right-handed scissors with your left hand. There is a problem in that it is difficult to check with the eyes, so accurate and straight scissors are difficult.

Accordingly, it is an object of the present invention to provide a two-handed scissors that can be converted to the left-handed scissors to be easily used by the left-handed scissors made for the right-handed.

In addition, another object of the present invention is to provide a two-handed scissors that can be used to modify the scissors in the form of the right-handed and left-handed to suit their habits with one scissors.

Two-handed scissors in accordance with the present invention for achieving the above objects, the first shear blades formed on the first edge and the second blade on both corners of one side; A second scissor blade having first and second blades formed at both corners of the side facing the first scissor blade; A rotating shaft member which penetrates and couples the first and second scissors blades to provide a central axis to rotate the first scissors blade and the second scissors blades, and is easy to fasten and detach; And a first handle and a second handle coupled to one end of the first and second scissors blades, so that the right-handed mode and the left-handed mode can be conveniently switched and used by anyone.

In this case, the first handle and the second handle of the two-handed scissors according to the present invention correspond to the coupling protrusions formed on the first and second scissors blades so as to be easily coupled and separated with the first and second scissors blades. Each of the coupling holes is preferably provided so that switching from the right-handed mode to the left-handed mode is possible without completely removing the rotary shaft member.

As described above, the present invention has the advantage that both the right-handed and left-handed can be conveniently used with one scissors.

Accordingly, there is no need to separately provide a right-handed scissors and a left-handed scissors, it is economical, it is possible to cut the desired object accurately, easily and safely.
