In some cables to be cut, the cables are cut by using the shear type structure, the shear type structure generally performs pressure-applying cutting on one side or two sides, the shear type structure is limited by the shape of the shear type structure, applied pressure cannot be offset, the cables are easy to offset during cutting, and the cables are easy to be directly torn off, and the acting force of the three cutters 46 can be offset by the cable cutting structure 4, so that the stability of the cable position is ensured, the offset of the cables is reduced, and the probability of tearing off the cables is reduced.
In summary, the first and second embodiments can directly cut the unbroken cable by using the scissor structure, while the third embodiment cannot directly cut the cable, and the cable needs to be cut first and then the end faces are arranged.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
