[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to safety pliers.

[0002]

[Prior art]

 As shown in FIG. 1, the conventional pliers for electric work mainly includes two operating arms 10 and 20 which are pivoted and connected to each other. A clip opening 40 is formed outside the pivot joint 30 and a cutting blade 50 is formed on the same side wall to provide the function of a clip or scissors. In addition, an auxiliary clip opening 60 on the inside, which has a rough surface along the adjacent walls of the two operation arms 10 and 20, is added to the inside of the pivot joint portion 30, and the workpiece is machined to a flat shape. It can also be used for pressurizing, clipping and other uses. The auxiliary clip opening 60 is formed by folding the two operation arms 10 and 20 adjacent to each other. When the two adjacent walls are sandwiched between them, they form a neat wall. Because of its sharp edge, a slight contact with the finger of the hand will sandwich the skin and meat as shown in FIG. The user has no way of preventing it. As shown in FIG. 3, some conventional pliers have a gap formed in the auxiliary clip opening 60 '. Then, the skin and meat are hard to scissors, but since the adjacent wall is still sharp, there is still a possibility that the skin and meat will be sandwiched unless care is taken as shown in FIG. In the worst case, the larger the gap, the less effective the clip is, and thus cannot gain both safety and functionality.

[0003]

[Problems to be solved by the invention]

 The purpose of the present invention is to provide safety pliers with high safety.

[0004]

[Means for Solving the Problems]

 Outside the pivot joint of the two operating arms, a clip opening is formed in the side wall of which a cutting blade or chuck is formed. An auxiliary clip opening is formed by opposing scissor planes near the handle inside the pivot joint of the two operating arms. Concavities and convexities consisting of a tooth pattern or a non-slip pattern are formed on the scissor plane facing the auxiliary clip opening. Concave, chamfered or convex arcs are formed at the outer ends of the opposing scissor planes of the auxiliary clip openings, respectively.

[0005] At the pivot joint of the two operating arms of the pliers, a suitable concave or chamfered or convex arc is provided at the two outer ends of the opposing scissor plane, respectively, approaching the auxiliary scissor opening inside the handle. Therefore, when the two operating arms are sandwiched in a closed state, a concave or protruding shape is formed on the surface of the inner adjacent wall to prevent the user from accidentally pinching the skin and meat of the hand and using it. Ensure time safety.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 5 and 6, the safety pliers according to the embodiment of the present invention mainly include two operation arms 1 and 2 which are pivoted and connected to each other. To provide the function of a clip or scissors, a clip opening 4 is formed outside the pivot joint portion 3 and a cutting blade 5 or a chuck is formed on the same side wall. An auxiliary clip opening 6 is formed inside the pivot joint portion 3 at a position approaching the handle by a pair of opposing scissor planes of the two operation arms 10 and 20. The opposite scissor plane of the auxiliary clip opening 6 has a rough surface such as a suitable tooth pattern or anti-slip pattern. Furthermore, since there are appropriate concave arcs (chamfers) 61 or convex arcs at the two outer ends of the scissor plane opposite the auxiliary clip opening 6 inside the pivot joint portion 3, the two operation arms are closed. When sandwiched, the inner adjacent wall becomes inclined and concave. However, the inner adjacent wall may be protruded.

As shown in FIG. 6, even if the user accidentally touches the adjacent gap, a safe inclined dent (or protruding) state is maintained at the contact point between the hand and the inner adjacent gap. It prevents hand and skin from being pinched, and ensures safety when using pliers.

The edge formed on the adjacent wall surface may be a concave arc, a chamfer, or a convex arc, and is not limited to a specific pliers form. The present invention can also be applied to the general electrical work of FIG. 5, the pliers of FIG. 7, or similar pliers. Similarly, the pliers shown in FIG. 8 are provided with an improved structure called a convex arc or a concave arc 61 on both sides of an auxiliary clip opening formed from opposing scissor planes, as described above, near the handle. I can. This results in a structure in which the auxiliary clip opening is closed while there is a density or gap.

[0009]

[Effect of the invention]

 According to the safety pliers of the present invention, at the pivot joint of the two operating arms of the pliers, appropriate concave and convex arcs are respectively provided at the two outer ends of the scissor plane facing the auxiliary scissor opening inside the handle. When the two operating arms are closed, even if the user accidentally touches the surface of the adjacent gap, the user does not pinch the skin and flesh of the hand, improving safety when using pliers. I do.
