[0003] According to a Chinese patent with the announcement number CN219418590U, a copper wire twisting device for cable processing is disclosed. The copper wire twisting device for cable processing linearly passes through the middle of a fixed disk, and then rotates the adjusting rod in turn to drive the arc-shaped tooth plate to clamp and position the copper wire in the middle, so as to prevent the copper wire from linearly loosening during the twisting process, thereby affecting the quality of the cable during the twisting process. The fixed disk fixes the single copper wire in turn, and the single copper wires between multiple fixed disks are twisted to form a cable, making the copper wire twisting process convenient and fast, saving time and effort.

[0045] Example 2:

[0046] On the basis of the above-mentioned embodiment 1, in order to prevent the rotating ring 904 from rotating at will, it is necessary to lock and limit the rotating ring 904, so the following structure is set.

[0047] Specifically, the clamping assembly 9 also includes a plurality of bolt holes 905 installed on one side of the winding disk 4. Each swivel 904 is equipped with a locking screw 906 extending into a bolt hole 905. After the arc-shaped tooth plate 911 clamps and positions the copper wire, the staff screws the locking screw 906 into the corresponding bolt hole 905 to lock and fix the swivel 904 to prevent the swivel 904 from rotating at will.

[0048] Example 3:

[0049] On the basis of the above embodiment 1, in order to improve the stability of the capstan 4 during rotation, a vague structure is provided.

[0050] See Figures 1-4 A circular hole 22 is provided on the fixed plate 2, and a slide groove 3 is provided on the inner wall of the circular hole 22. A slip ring 5 is provided inside the slide groove 3. The slide groove 3 is ring-shaped.

[0051] The working principle of the present invention is as follows: first, before using the device, the power is turned on, and then the copper wire is passed through the cylinder 21 in sequence. Then, the staff rotates the swivel 904 through the handle 912. When the swivel 904 rotates, it pushes the push plate 909 to rotate, and the push plate 909 can push the limit block 908 to move, and the four limit blocks 908 can be moved at the same time, and the movable rod 910 can be moved, and then the arc-shaped tooth plate 911 can be moved. The simultaneous movement of the four arc-shaped tooth plates 911 facilitates the clamping and positioning of the copper wire. After the copper wire is clamped, the locking screw 906 is screwed into the corresponding bolt hole 905 to lock and fix the swivel 904 and prevent the swivel 904 from rotating.

[0052] Then, the first motor 8 is started. The first motor 8 drives the gear 7 to rotate, the gear 7 drives the ring gear 6 to rotate, and the ring gear 6 drives the stranding disc 4 to rotate, so that the copper wire can be twisted. The twisted cable passes through the through hole 12 and is wound around the winding roller 20. The second motor 13 is started. The second motor 13 drives the first rotating seat 15 to rotate, and then drives the winding roller 20 to rotate, so that the winding roller 20 winds up the cable.

[0053] When the height of the support 11 needs to be adjusted, the electric push rod 10 can be started to extend and retract the piston rod, thereby driving the support 11 to move, thereby facilitating the adjustment of the height of the support 11.
