[0025] In specific use, after the cable is fixed in the main bridge frame 1, the limiting transverse plate 11 arranged at the open end of the main bridge frame 1 is used to facilitate the precise butt joint of the side plate 2.

[0026] Preferably, the connecting end of the main bridge 1 and the transverse bridge 5 is provided with a rectangular groove, and the rectangular grooves of the main bridge 1 and the transverse bridge 5 are communicated with each other, and the vertical end of the moving plate 4 is in the rectangular groove communicated with the main bridge 1 and the transverse bridge 5.

[0027] In specific use, the moving plate 4 is slid to one side of the transverse bridge 5 at the front end of the side plate 2, so that the moving plate 4 is inserted into the transverse bridge 5.

[0028] Preferably, the adjusting groove 3 is a rectangular through groove arranged in parallel, and the shape and size of the through groove are matched with the horizontal end of the "j" type handle at the front end of the moving plate 4.

[0029] In specific use, the adjusting groove 3 at the front end of the side plate 2 is used to facilitate the movement of the slidingly connected moving plate 4 in the adjusting groove 3.

[0031] In specific use, the limiting frame 8 is abutted on the back side surface on both sides of the opening end of the main bridge 1, the third bolt assembly 9 is used to fix the position of the limiting frame 8 on the surface of the main bridge 1, then the limiting frame 8 is sleeved on the surface of the transverse bridge 5 by the extended position of the limiting frame 8, and the second bolt assembly 7 is used to fix the connection of the limiting frame 8 and the transverse bridge 5.

[0032] Preferably, the main bridge 1, the moving plate 4, the transverse bridge 5 and the first bolt assembly 6 form a threaded connection structure.

[0033] In specific use, the moving plate 4 is slid to one side of the transverse bridge 5 at the front end of the side plate 2, so that the moving plate 4 is inserted into the transverse bridge 5, and the first bolt assembly 6 is used to fix the connection of the moving plate 4 and the transverse bridge 5, so as to fix the position of the transverse bridge 5 on one side of the main bridge 1.

[0034] Preferably, the main bridge 1 is a "V" type structure, the ventilation net 10 is arranged on both sides of the inclined end of the main bridge 1, and the ventilation net 10 is a circular structure and is a net frame made of stainless steel.

[0035] In specific use, the ventilation net 10 arranged on the inclined end of the surface of the main bridge 1 can improve the ventilation and heat dissipation efficiency of the bending part of the main bridge 1, so as to avoid that the bending cable accumulates too much heat and affects the service life and performance of the cable.

[0036] The working principle is as follows: during the cable laying process, the main bridge 1 plays a key role. The built-in laying channel provides a convenient laying path for the cable and ensures the fixation of the cable position. When the laying route encounters obstacles, the bending design of the main bridge 1 enables the cable to easily cross over, ensuring the smooth progress of the laying work. After the cable is fixed in the main bridge 1, the design scheme utilizes the limiting transverse plate 11 at the open end of the main bridge 1, which greatly facilitates the precise butt joint of the side plate 2. After the butt joint is completed, the side plate 2 is firmly welded at the open end of the main bridge 1, enhancing the stability of the structure. When the main bridge 1 needs to be butt jointed and fixed with the transverse bridge 5 at both ends, the limiting frame 8 is used, which abuts against the rear side surface on both sides of the open end of the main bridge 1 and is fixed in position through the third bolt assembly 9. The part of the limiting frame 8 extending outward is sleeved on the surface of the transverse bridge 5, and then the second bolt assembly 7 is used to realize the close connection between the limiting frame 8 and the transverse bridge 5. Then, the rectangular slot opened at the front end of the side plate 2 provides space for the sliding of the moving plate 4. The moving plate 4 slides to the side of the transverse bridge 5 at the front end of the side plate 2 until it is inserted into the transverse bridge 5, and then it is fixed and connected through the first bolt assembly 6. This step ensures the precise positioning and stable fixation of the transverse bridge 5 at both sides of the main bridge 1. In addition, the inclined end of the surface of the main bridge 1 is provided with the ventilation net 10, which not only improves the ventilation and heat dissipation efficiency of the bending part of the main bridge 1, but also effectively avoids the performance degradation and shortens the service life of the cable due to heat accumulation.
