[0035] Specifically, the outermost layer of the cable is an outer sheath layer 201 made of wear-resistant material, which can help the cable resist external wear and provide protection. A metal shielding layer 202 is provided on the inner side of the outer sheath layer 201. The metal shielding layer 202 can significantly improve the shielding performance of the cable against external electromagnetic interference, ensuring that the signal transmitted inside the cable is not affected by external electromagnetic waves. Immediately inside the metal shielding layer 202, a filling layer 203 is provided. The filling layer 203 is used to fill the space inside the cable to ensure the compactness of the internal structure of the cable. At the same time, a fiber cross bundle 205 is designed in the middle of the filling layer 203. The fiber cross bundle 205 can not only fix multiple inner sheaths Layer 206, and can also ensure that the positions of multiple cores 207 remain unchanged, to avoid them from being entangled and moving inside the cable, the function of the inner sheath layer 206 is to provide inner layer protection for the cores 207, to prevent short circuits between the cores 207, and to ensure the safety and service life of the cable, in addition, fiber bundles 204 are specially arranged around the filling layer 203, this design combined with the fiber cross bundle 205 can not only further fix the cores 207, but also greatly increase the bending resistance of the cable, so that the cable can maintain good performance and structural stability during use, greatly improve the bending resistance of the cable, and improve the practicability of the device.

[0036] Reference Figure 2 、 Figure 3 and Figure 5 , one side of the two first fixing plates 12 and the two second fixing plates 23 are fixedly connected with an anti-slip pad 13, the sizes of the two outer sheath layers 201 match the inner sizes of the first fixing plates 12 and the second fixing plates 23, the bottom of the fixing card 1 is fixedly connected with an anti-slip layer 15, and the top of the rotating rod 6 is fixedly connected with a turning handle 16;

[0038] Reference Figure 1 and Figure 5 A cover plate 18 is provided on the top of the fixed card 1. The left side of the cover plate 18 is rotatably connected to the top of the fixed card 1 through a rotating shaft 17. A ventilation window 19 is provided on the top of the cover plate 18. A pull ring 20 is rotatably connected to the right side of the top of the cover plate 18. The left and right rear ends of the fixed card 1 are fixedly connected to fixed columns 21. The left and right front ends of the fixed card 1 are provided with holes 22.

[0039] Specifically, the cover 18 can be opened by the rotating shaft 17, and the cable can be disassembled and installed at this time, and the cable can be cooled through the ventilation window 19.

By engaging the fixing columns 21 of multiple fixing cards 1 with the holes 22, multiple fixing cards 1 can be connected to form a drag chain.

[0040] Working principle: When installing the cable, first put the cable into the inside of the fixing card 1. At this time, you need to rotate the rotating rod 6 first. The rotation of the rotating rod 6 will drive the active bevel gear 7 to rotate. Since the driven bevel gear 5 is engaged with the active bevel gear 7, when the active bevel gear 7 rotates, the driven bevel gear 5 will drive the bidirectional threaded rod 4 to rotate. At this time, since the sliders 8 on both sides are limited by the slide groove 14, when the bidirectional threaded rod 4 rotates, the sliders 8 on both sides will move to both sides and drive the support plate 9 to move to both sides. The support plate 9 will drive the first fixed rod 10 to move to both sides. At this time, the first fixed plate 12 will move to both sides. At this time, the cable can be placed between the first fixed plate 12 and the second fixed plate 23 to fix it. When the fixing card 1 moves, the cable will not rub or collide with the fixing card 1, thereby increasing the service life of the cable.

[0041] In addition, the outermost layer of the cable is wrapped by an outer sheath layer 201 made of wear-resistant material, and a metal shielding layer 202 is arranged on the inside of the outer sheath layer 201. The metal shielding layer 202 is used to improve the cable's shielding performance against external electromagnetic radiation. A filling layer 203 is arranged on the inside of the metal shielding layer 202 to fill the internal space of the cable. At the same time, a fiber cross bundle 205 is arranged in the middle of the filling layer 203. The fiber cross bundle 205 can fix multiple inner sheath layers 206, so that the positions of multiple cores 207 will not change, avoiding their entanglement inside the cable. At the same time, the inner sheath layer 206 can provide inner layer protection for the cores 207 to avoid short circuits between the cores 207, and fiber bundles 204 are arranged around the filling layer 203. Through the dual design of the fiber cross bundle 205 and the fiber bundle 204, the bending resistance of the cable can be greatly increased.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
