This utility model puts forward the problems that "the traditional shearing structure is not convenient for limiting the tip shear blade, resulting in serious radial force and affecting the shearing force, and most of the shearing structures are fixed by welding, which is not convenient for disassembly and assembly and inconvenient for maintenance", and proposes the following technical solution: "When the wire to be sheared moves to the right through the cutting groove and reaches the required shearing length, one blade moves downward and one blade moves upward to cut the wire, and then the two blades return to their initial positions respectively to shear the next wire, and so on to complete the shearing work of the whole wire. Compared with the prior art, the beneficial effect of this utility model lies in that: the front end of the tool holder is divided into two connecting parts by the cutting groove, which is convenient to manufacture and has low production cost; the two blades are respectively connected to the two connecting parts, the connection is stable, the wire is cut in the cutting groove, it is convenient to use and has high shearing accuracy". However, this technical solution lacks measures to meet different lengths of cables. Since the lengths of cables are different, different bunching structures need to be equipped to perform bunching operations on the cables, thus increasing additional costs.
