[0025] The driving mechanism 4 drives the roller 2 to rotate, so that the stranding mechanism 3 twists the multiple cable wires, and then the twisted cables are cut by the cutter member 62. When the cutter member 62 needs to be replaced, the cutter member 62 is separated from the mounting seat 61 by manually operating the limit member 63, and then a new cutter member 62 is replaced to cooperate with the mounting seat 61, and then the limit member 63 is manually operated to fix the new cutter member 62 to the mounting seat 61 to achieve the installation of the cutter member 62. The whole process is simple to operate, and the cutter member 62 can be quickly replaced, which greatly reduces the amount of manual labor.

[0026] Furthermore, the cutter member 62 includes a mounting block 621, one end of which is fixedly connected to a clamping block 622, which is slidably matched with the mounting seat 61, a clamping slot 64 matching the clamping block 622 is provided on one side of the mounting seat 61, the clamping block 622 is slidably matched with the clamping slot 64, a screw rod 623 that penetrates the mounting block 621 is threadedly connected to the middle of the mounting block 621, one end of the screw rod 623 is rotatably connected to an arc plate 624, a cutter 625 is fixedly connected to the inner side of the arc plate 624, and a rotating cap 626 is fixedly connected to the other end of the screw rod 623. By rotating the rotating cap 626, the screw rod 623 and the mounting block 621 can move relative to each other, so that the two arc plates 624 can move toward each other, and the two cutters 625 can be translated toward each other to cut the twisted cables.

[0027] Furthermore, the limiting member 63 includes a slide rod 631, which passes through the top wall of the mounting seat 61 and extends to the inner side of the card slot 64. The slide rod 631 is slidably connected to the top wall of the mounting seat 61.

One end of the roller 2 is fixedly connected with a gear 2 43 which meshes with the gear 1 42. By introducing different cable strands into different stranding grooves 32, and then starting the motor 41 to rotate the gear 1 42, the gear 2 43 drives the roller 2 to rotate synchronously, so that the limit plate 31 rotates, so that all the cable strands are twisted toward the center, thereby completing the twisting of the cable strands.
