[0036] In this embodiment, in order to achieve the effect of keeping the wires tensioned, a pre-tightening component 4 is designed. A pair of slideways 4-1 are provided inwardly on the surface of the extension plate 3. An adjusting screw 4-2 and a movable frame 4-3 are provided in the slideway 4-1. The adjusting screw 4-2 can be turned to control the synchronous movement of the two movable frames 4-3. A frame 4-4 is provided at the bottom front end of the movable frame 4-3.

[0043] Furthermore, one end of the sleeve 5-1 is a trumpet-shaped opening structure.

[0044] In this embodiment, the trumpet-shaped opening structure allows the wires to be conveyed outward at any angle, further reducing wear on the cables.

[0045] When it is needed, the cable is passed through the rolling rods 5-3, the sleeve 5-1, and then around the first guide wheel 4-6 and the second guide wheel 4-15. After entering the tube stranding machine body 2, the compression frame 4-17 is put on the top of the column 4-13 and pressed on the outside of the second guide wheel 4-15 to compress the wire. During the cabling process, the position of the frame 4-4 can be adjusted by turning the adjusting screw 4-2 according to the tension of the wire, and the adjusting screw can be turned to control the rotation of the rotating frame 4-11. The tension between the first guide wheel 4-6 and the second guide wheel 4-15 can be increased by increasing the angle.
