The inner wall of the horizontal slide 703 is slidably connected to the outer wall of the two limit slide rails 401, and the upper surface of the horizontal slide 703 is fixedly connected to the lower surface of the connecting block 606, and the lower surface of the horizontal slide 703 is symmetrically provided with two limit grooves B704, and the inner sides of the two limit grooves B704 are slidably connected to the hinge blocks 705, and the outer sides of the multiple hinge blocks 705 are hinged with hinge plates 706, and the ends of the multiple hinge plates 706 are hinged with rotating columns 707, and the outer walls of the multiple rotating columns 707 are respectively hinged to the outer sides of multiple hinges 509.

[0041] In this embodiment, when it is necessary to lay the wires inside the bridge body 1, the two threaded connecting rods 602 are rotated synchronously by rotating the knob 6031, and at the same time, the two threaded connecting rods 602 are in threaded cooperation with the two connecting pieces 604, thereby causing the two connecting pieces 604 to move synchronously towards the two ends of the handle 603, and at the same time, the adjusting rod 605 pushes the horizontal plate 4 and the horizontal sliding seat 703 synchronously downwards through the connecting block 606, and at the same time, the horizontal frame 701 does not move downwards synchronously due to the support of the limiting seat, and at the same time, the horizontal sliding seat 703 moves downwards synchronously, thereby causing the multiple hinge plates 706 to be stressed, and at the same time, the multiple hinge plates 706 are in sliding cooperation with the multiple hinge blocks 705 through the limiting groove B704, thereby causing the angle between the multiple hinge plates 706 to be enlarged, and at the same time, the hinge plate 706 is stressed by the rotating column 707 hinge piece 509, thereby causing the hinge piece 509 to adjust the distance between the clamping assemblies 5 in proportion to the change of the angle of the hinge plate 706, thereby causing the wires inside the bridge body 1 to be more orderly and less chaotic, and at the same time, the distance between the wires is adjusted, the heat dissipation holes 404 in the horizontal plate 4 above the clamping assemblies 5 are opened, thereby increasing the air flow space between the wires inside the bridge body 1, thereby preventing poor heat dissipation, and then when the distance between the clamping assemblies 5 is adjusted, the horizontal sliding seat 703 continues to move downwards, thereby causing the hinge piece 509 to push one of the racks 508 to move downwards, thereby facilitating the clamping assemblies 5 to complete the clamping work of the wires.

[0042] In this embodiment, as shown in Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 11As shown, the lower surface of the inside of the bridge body 1 is symmetrically provided with two baffles 9, and a plurality of bottom plates 901 are slidingly connected between the inner sides of the two baffles 9. The inner walls of the plurality of bottom plates 901 are each provided with a limiting groove C902, and the inner sides of the plurality of limiting grooves C902 are respectively slidingly connected with the outer sides of the plurality of L-shaped connecting frames 8. A support frame A903 is fixedly connected to the upper surface of the bottom plate 901 near one end of the limiting groove C902, and a roller A904 is rotatably connected to the inner side of the support frame A903. A plurality of support frames B905 are provided above the plurality of rollers A904, and the upper end of the plurality of support frames B905 is slidingly connected with the inner side of one of the limiting sliding grooves 402. One side of each of the plurality of support frames B905 is fixedly connected with an L-shaped sliding seat 10, and the outer side of the other end of each of the plurality of L-shaped sliding seats 10 is slidingly connected with the inner side of the other limiting sliding groove 402.

The end of the memory spring 1203 is fixedly connected with the inner wall of the mounting groove A12.

[0043] In this embodiment, while the clamping assembly 5 is performing the equal proportion spacing adjustment work, the slide plate 11 and the L-shaped connecting frame 8 will respectively apply force to the L-shaped slide seat 10 and the bottom plate 901, so that the bottom plate 901 and the L-shaped slide seat 10 can be adjusted synchronously with the spacing adjustment of the clamping assembly 5, thereby enabling the support frame A 903 and the support frame B 905 to respectively drive the rollers A 904 and the rollers B 1202 to adjust synchronously, so that the rollers A 904 and the rollers B 1202 can always correspond to the center of the annular slide seat B. Then, by pushing the handle 603, the connecting block 606 moves through the horizontal slide seat 703, and the horizontal slide seat 703 moves while driving the vertical frame 702 to drive the horizontal frame 701 to move synchronously, and then the horizontal frame 701 moves to drive multiple clamping assemblies 5 to move synchronously, thereby completing the laying of the wire. The rolling friction of the wire on the rollers A 904 replaces the direct sliding friction between the wire and the inside of the bridge body 1 during the laying process, thereby reducing the wear of the wire skin during the laying process, thereby increasing the service life of the wire. At the same time, by sliding the horizontal plate 4 downward, the rollers B 1202 can move closer to the rollers A 904, thereby extruding the wire on the rollers A 904, thereby increasing the tension of the wire during laying, thereby further avoiding the phenomenon of crossing between cables due to looseness during laying. At the same time, during the extrusion of the wire by the rollers A 904 and the rollers B 1202, the buffer force generated by the memory spring 1203 avoids damage to the wire due to excessive pressure when the rollers A 904 and the rollers B 1202 increase the tension of the wire.

[0047] When the work of laying the wires inside the bridge body 1 is needed, first, the wires to be laid are put into the inside of the annular slide B in turn, supported and lifted by the arc-shaped plate 512, then the two threaded connecting rods 602 are rotated synchronously by rotating the knob 6031, while the two threaded connecting rods 602 are rotating, they are matched with the two connecting pieces 604 through threads, then the two connecting pieces 604 are synchronized to move towards the two ends of the handle 603, while the two connecting pieces 604 are moving towards the two ends of the handle 603, the adjusting rod 605 pushes the horizontal plate 4 and the horizontal slide 703 downwards synchronously through the connecting block 606, while the horizontal slide 703 is moving downwards, the hinge block 705 is moving downwards synchronously, while the hinge block 705 is moving downwards, the multiple hinge plates 706 are stressed, and through the sliding cooperation between the limiting groove B704 and the multiple hinge blocks 705, the angle between the multiple hinge plates 706 can be expanded, while the hinge plate 706 can be stressed through the rotating column 707, the hinge piece 509 can adjust the distance between the clamping assemblies 5 in proportion while the angle of the hinge plate 706 changes, the wires inside the bridge body 1 can be laid more regularly and orderly, the situation of disorder and intersection can be reduced, through the adjustment of the distance between the wires, the heat dissipation holes 404 on the horizontal plate 4 above the clamping assemblies 5 are opened, the air flow space between the wires inside the bridge body 1 is increased, then when the distance between the clamping assemblies 5 is adjusted, the hinge piece 509 pushes one of the racks 508 downwards, then one of the gears 507 is rotated through the meshing between one of the racks 508 and one of the gears 507 during the downward movement of one of the racks 508, one of the gears 507 is rotated, then the rotating tooth ring 506 is rotated synchronously through the meshing between the outer edge of one of the gears 507 and the teeth of the rotating tooth ring 506, while the rotating tooth ring 506 is rotating, the multiple gears 507 are rotated synchronously through the meshing between the rotating tooth ring 506 and the multiple gears 507, then the multiple gears 507 are meshed with the multiple racks 508, the multiple racks 508 are moved towards the inside of the annular seat B502 synchronously, then the multiple racks 508 are clamped by the arc-shaped plate 512 through the arc-shaped seat 510, while the arc-shaped plate 512 is clamping the wires, the arc-shaped plate 512 can produce different clamping forces according to the different thicknesses of the wires through the elastic force of the supporting spring A511, the application range of the clamping assembly 5 is increased, while the clamping assembly 5 is adjusting the distance in proportion, the slide plate 11 and the L-shaped connecting frame 8 stress the L-shaped slide 10 and the bottom plate 901 respectively,The bottom plate 901 and the L-shaped slide 10 can be adjusted synchronously with the spacing adjustment of the clamping assembly 5, thereby enabling the support frame A 903 and the support frame B 905 to drive the rollers A 904 and the rollers B 1202 to move synchronously, so that the rollers A 904 and the rollers B 1202 can always correspond to the center of the annular slide B. Then, by pushing the handle 603, the connecting block 606 moves through the horizontal slide 703, and the horizontal slide 703 moves while driving the horizontal frame 701 synchronously through the vertical frame 702. Subsequently, the horizontal frame 701 moves, thereby driving multiple clamping assemblies 5 to move synchronously, to complete the laying of the wire. The rolling friction of the wire on the rollers A 904 replaces the direct sliding friction between the wire and the inside of the bridge body 1 during the laying process, thereby reducing the wear of the wire during the laying process and increasing the service life of the wire. Meanwhile, by sliding the horizontal plate 4 downward, the rollers B 1202 can move closer to the rollers A 904, thereby pressing the wire on the rollers A 904 to increase the tension of the wire during the laying process, thereby further avoiding the entanglement and crossing of cables during the laying process. Meanwhile, during the pressing of the wire by the rollers A 904 and the rollers B 1202, the buffer force generated by the memory spring 1203 avoids damage to the wire caused by excessive pressure when the rollers A 904 and the rollers B 1202 increase the tension of the wire. By synchronously pressing the two clamping pieces 1405, the extension rod 1404 drives the top block 1401 to move downward inside the installation slot B 13 through the sleeve rod 1403. The top block 1401 moves downward while compressing the supporting spring B 14 and driving the clamping column 1402 to move downward along the inside B of the installation slot B 13, so that the clamping column 1402 and the slot hole 1301 are separated. When the clamping piece 1405 is pressed to correspond to the slot of the positioning slot 1302, the extension rod 1404 and the sleeve rod 1403 are retracted by pushing the clamping piece 1405, so that the outside of the clamping piece 1405 and the inside of the positioning slot 1302 are clamped, thereby fixing the state of the top block 1401 after being pressed downward. Subsequently, the cover plate 15 covers the bridge body by sliding between the cover plate 15 and the limiting slide A 101. When the cover plate 15 completely covers the bridge body 1, the clamping piece 1405 is separated from the positioning slot 1302 by pulling the clamping piece 1405. Subsequently, the top block 1401 is rapidly pushed upward by the tension of the supporting spring B 14, so that the top block 1401 synchronously pushes the clamping column 1402 upward, so that the outside of the clamping column 1402 and the inside of the limiting clamping slot 1501 are clamped, thereby fixing the state of the cover plate 15 and the bridge body 1. Thus, the disassembly and assembly of the cover plate 15 and the bridge body 1 are more convenient.In this way, the inside of the bridge body 1 is easily maintained.
