[0002] With the rapid deployment of new information infrastructure such as 5G, F5G, and computing power networks, communication engineering places higher demands on the capacity, reliability, and construction efficiency of optical cable lines. Overhead, duct, and direct burial are currently the three mainstream laying methods in China. Among them, the overhead method remains the preferred choice for secondary trunk lines and metropolitan area access networks due to its shorter construction period, lower investment, and convenient expansion. Existing equipment is mostly "one cable, one adapter," meaning that when laying optical cables of various diameters from Φ8 to Φ30 mm simultaneously in a project, multiple sets of clamps or netting are required, increasing material preparation and transportation costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides an end-pulling device for optical cable laying in communication engineering, including a traction box 1. The bottom of the inner cavity of the traction box 1 is provided with a cable seat 2 and a guide seat 3. The top of the traction box 1 is provided with an adjustment component 4, which includes a moving groove 41. The moving groove 41 is rotatably connected to the inner cavity of the moving groove 41, and an elastic fixing component 44 is threadedly connected to the outer side of the threaded rod 42. Below the elastic fixing component 44 is a cable wheel 45 located within the inner cavity of the traction box 1. The top of the traction box 1 is inclined, and the threaded rod 42 is parallel to the top surface of the traction box 1. By rotating the threaded rod 42, the elastic fixing component 44 can be moved along the inner cavity of the moving groove 41, thereby moving the cable wheel 45 on the elastic fixing component 44. Because the top of the traction box 1 is inclined and the threaded rod 42 is parallel to the top surface of the traction box 1, it is easy to adjust the distance from the bottom of the cable wheel 45 to the top of the cable seat 2, making it easy to fix optical cables of different diameters and adaptable to use with optical cables of different diameters.

[0021] As a further improvement of this utility model, the adjusting component 4 also includes a turntable 43, one end of which is connected to the turntable 43, and the top of the turntable 43 protrudes from the top of the traction box 1. By setting the turntable 43, it is convenient for the operator to control the threaded rod 42 using the turntable 43, thereby controlling the position of the elastic fixing component 44 and the cable wheel 45.

[0022] As a further improvement of this utility model, the elastic fixing component 44 includes a movable plate 441, an adjusting frame 442, and a spring 443. The upper part of the movable plate 441 is threadedly connected to the threaded rod 42. The adjusting frame 442 is rotatably connected to the front and rear sides of the movable plate 441. A cable wheel 45 is rotatably connected to one side of the adjusting frame 442. The spring 443 is connected to the side of the movable plate 441, and the bottom end of the spring 443 is connected to the top of the adjusting frame 442. By connecting the cable wheel 45 to the threaded rod 42 via the movable plate 441, the adjusting frame 442, and the spring 443, it is convenient to pull the optical cable from one side of the cable wheel 45 when the optical cable passes through the bottom of the cable wheel 45, and it is difficult to pull the cable from the other side of the cable wheel 45. This also makes it convenient to use the cable when it is fixed between the cable wheel 45 and the cable seat 2, and the cable can be pulled from one side.

[0023] As a further improvement of this utility model, the outer side of the threaded rod 42 is provided with several elastic fixing components 44 and cable wheels 45, and the bottoms of the several cable wheels 45 are on the same horizontal plane. By setting multiple sets of elastic fixing components 44 and cable wheels 45, the range of fixing optical cables is increased, and the stability is improved.

[0024] As a further improvement of this utility model, a movable opening 5 is provided on the front side of the traction box 1. A connecting shaft 6 is movably sleeved in the inner cavity of the movable opening 5. The rear side of the connecting shaft 6 is connected to the cable wheel 45, and a mounting plate 7 is connected to the front side of the connecting shaft 6. A threaded hole 8 is provided on the mounting plate 7. By setting the connecting shaft 6, the mounting plate 7, and the threaded hole 8, the cable wheel 45 can be driven from the outside, which can drive the cable wheel 45 to rotate and automatically transport the cable.

[0025] As a further improvement of this utility model, a rubber seat 9 is installed on the rear side of the traction box 1, and a fixing strap 10 is connected to the rear side of the rubber seat 9. By setting the rubber seat 9 and the fixing strap 10, it is easy to fix this device to the arm for use, making it convenient for workers to carry when climbing for installation.

[0026] Working principle: When using this device, insert the cable end into the traction box 1 and pass through the guide seat 3. Rotate the turntable 43 to drive the threaded rod 42 to rotate. Since the threaded rod 42 is threadedly connected to the moving plate 441, it drives the moving plate 441, the adjusting frame 442 and the cable wheel 45 to move along the inner cavity of the moving groove 41, so that the cable wheel 45 contacts the cable and fixes the cable. When the cable is needed and there is no power, move the cable wheel 45 to a position where it is not tightly connected to the cable. By pulling the cable, the cable can be pulled out for use. When the worker is climbing to install, the traction box 1 can be fixed to the arm with the rubber seat 9 and the fixing strap 10 for easy carrying. Connect the mounting plate 7 and the threaded hole 8 to the external output end, which can drive the cable wheel 45 to rotate and realize the automatic cable output function.
