Referring to fig. 1 to 6, a shearing tool 100, specifically a pair of scissors, is shown in an embodiment of the present utility model, which can perform shearing treatment on materials such as wires and films, so as to meet the processing requirements.

Illustratively, the shearing tool 100 includes a first shank 10 and a second shank 20, the end of the first shank 10 being provided with a first blade 11 and a second blade 12, the first blade 11 and the second blade 12 being spaced apart in the thickness direction of the shearing tool 100; the second cutter handle 20 is rotationally connected with the first cutter handle 10, a third cutting edge 21 and a fourth cutting edge 22 are arranged at the end part of the second cutter handle 20, the third cutting edge 21 and the fourth cutting edge 22 are arranged at intervals along the thickness direction of the shearing tool 100, the third cutting edge 21 and the first cutting edge 11 are correspondingly arranged and matched to form a first shearing assembly, and the fourth cutting edge 22 and the second cutting edge 12 are correspondingly arranged and matched to form a second shearing assembly.

It will be readily appreciated that the shear tool 100 is essentially a double shear tool, i.e., the first shear assembly constitutes one pair of scissors and the second shear assembly constitutes the other pair of scissors.

Because the first shearing component and the second shearing component are arranged at intervals in the thickness direction of the shearing tool 100, a safety interval with a certain width is formed between the first shearing component and the second shearing component, and the safety interval can enable the first shearing component and the second shearing component to finish the same shearing operation at the same time and enable any one of the first shearing component and the second shearing component to perform the shearing operation independently.

In summary, implementing the technical scheme of the embodiment has the following beneficial effects: when the shearing tool 100 of the above scheme is applied to the production of coiled wire products, in the occasion of shearing the coiled wire tail, the first knife handle 10 is rotationally connected with the second knife handle 20, the first knife handle 10 is simultaneously provided with the first knife edge 11 and the second knife edge 12, and the second knife handle 20 is simultaneously provided with the third knife edge 21 and the fourth knife edge 22, so that the first knife edge 11 and the third knife edge 21 can be matched to form a first shearing assembly, and the second knife edge 12 and the fourth knife edge 22 can be matched to form a second shearing assembly, and because the first shearing assembly and the second shearing assembly are respectively arranged in the thickness direction of the shearing tool 100 at intervals relatively, when the wire tail of the coiled wire product is left or right, the shearing tool 100 can correspondingly shear the left wire tail or right wire tail through the first shearing assembly only by short-distance transverse translation.

Compared with the prior art, the shearing tool 100 does not need to be turned over manually, so that the labor intensity is reduced, the labor cost is reduced, the turning mechanism is not required to be assembled for the shearing tool 100, the equipment investment and the cost are reduced, the occupied space of a field is reduced, and the machining efficiency can be remarkably improved.

Furthermore, in further embodiments, the outer side wall of the first blade 11 is provided with a first bevel 111 inclined towards the inner side of the shear tool 100, the outer side wall of the third blade 21 is provided with a second bevel 211 inclined towards the inner side of the shear tool 100, the first bevel 111 being closable with the second bevel 211 to form a first recess; the outer side wall of the second blade 12 is provided with a third inclined surface 121 inclined toward the inner side of the shear tool 100, the outer side wall of the fourth blade 22 is provided with a fourth inclined surface 221 inclined toward the inner side of the shear tool 100, and the third inclined surface 121 and the fourth inclined surface 221 can be closed to form a second concave portion. During shearing operation, the first concave part and the second concave part can contain the end part of the product, so that the first shearing assembly and the second shearing assembly are closer to the tail of the coiled wire, and the tail after shearing is closer to the end part of the product.
