When the first handle and the second handle are grasped so as to be positioned at, the pressing piece of the nipper blade presses the outer surfaces of the first support and the second support to engage the cutting blade to perform a cutting action. It is characterized by being returned to the original position by.

The side of the first support and the second support of the nipper blade body is characterized in that it further comprises an emboss (emboss) in the longitudinal direction to reinforce the rigidity of the nipper blade.

It is assembled through the lower portion of the shaft has a suitable width and length, and is positioned above the cutting blade inside the nipper blade body, characterized in that it comprises a scattering prevention plate to prevent the cutting off.

The nipper of the present invention can be made integrally by bending the nipper body in a 'U' shape, and thus it is easy to manufacture and has an effect of lowering the manufacturing cost due to productivity improvement.

In addition, the elastic part of the integrated nipper blade body is farther away from the cutting blade, so that it operates more smoothly, and the shaft hole of the handle is located in front of the elastic part of the nipper blade body so that the pressing piece of the handle is closer to each other. The pressing force of the nipper body is low, which makes the user easy to use.

In addition, by cutting the object by grasping the nipper blade through the handle and then releasing the handle, it is elastically restored by the elastic portion of the nipper blade, thereby eliminating the need for a blade spring that is basically required in the existing nipper.

In addition, by manufacturing the nipper body separated from the handle, there is an effect that can significantly reduce the manufacturing cost due to the homogenization of quality and productivity improvement due to the mass production of the nipper body.
