Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 As shown, a cable bridge comprises a bottom plate 1, a rivet 2 is fixedly connected to the surface of the bottom plate 1, a support rod 3 is fixedly connected to the top surface of the bottom plate 1, a cross bar 4 is fixedly connected to the inner side of the support rod 3, a shell 5 is placed on the surface of the cross bar 4, a clamping strip 9 is fixedly connected to the inner wall of the shell 5, a support frame 10 is clamped and installed inside the clamping strip 9, a slider 11 is slidably installed on the surface of the support frame 10, a support groove 12 is fixedly connected to the top surface of the slider 11, and a cable body 14 is clamped and installed inside the support groove 12;

[0024] Furthermore, the shape of the front end of the crossbar 4 is inclined upward, and the number of crossbars 4 arranged on the surface of a single support rod 3 is three;

[0025] During operation, the structure design in which the front end of the cross bar 4 is tilted upward reduces the possibility of the housing 5 falling, thereby improving the stability of the housing 5 during installation.

[0026] Furthermore, a clamping plate 6 is fixedly connected to the side of the housing 5 near one end, and mounting holes 7 are provided on the surfaces of the housing 5 and the clamping plate 6. Bolts 8 are provided through the mounting holes 7, and two adjacent housings 5 ​​are fixedly connected by the bolts 8.

[0027] During operation, the structural design in which two adjacent shells 5 are fixedly connected by bolts 8 facilitates assembly and disassembly of the device, thereby improving the adaptability of the device.

[0028] Furthermore, the front thread of the slider 11 is matched with a knob 13, and one end of the knob 13 penetrates through the surface of the slider 11 and presses against the surface of the support frame 10;

[0029] During operation, the knob 13 is conveniently used to fix the slider 11 by virtue of the structural design that one end of the knob 13 penetrates through the surface of the slider 11 and abuts against the surface of the support frame 10 .

[0030] Furthermore, the inner wall of the housing 5 is fixedly connected with a U-shaped groove 15, the inside of the U-shaped groove 15 is rotatably connected to the two ends of the roller 16, and the surface of the roller 16 is attached with the cable body 14;

[0031] During operation, the surface of the roller 16 is in contact with the cable body 14 , so that the friction between the roller 16 and the cable body 14 is reduced, thereby facilitating the cable body 14 to move within the housing 5 .

[0032] Furthermore, the support frame 10 is arranged near the two ends of the housing 5, and a roller 16 is arranged near the center of the housing 5, and the height of the roller 16 is higher than the height of the support frame 10;

[0033] During operation, the cable body 14 is conveniently clamped, fixed and moved by the structural design that the support frame 10 is close to the two ends of the housing 5 and the roller 16 is close to the center of the housing 5 .

[0034] Working principle: First, slide the slider 11 on the surface of the support frame 10 to a suitable position, tighten the knob 13 so that one end of the knob 13 passes through the slider 11 and presses it tightly to fix the position of the slider 11, and mount the cable body 14 on the surface of the support groove 12 to control the distance between the cables, and slide the roller 16 in the U-shaped groove 15. Since the surface of the roller 16 fits the surface of the cable body 14 and the height of the roller 16 is higher than the height of the support frame 10, the friction between the roller 16 and the cable body 14 is reduced, which facilitates the movement of the cable body 14 in the housing 5, and aligns the mounting hole 7 on the other side of the adjacent housing 5 through the clamping plate 6 on one side of the housing 5, and fixes the adjacent housings 5 ​​by passing the bolt 8 through the mounting hole 7.
