The adjusting assembly 9 includes a connecting head 91, a slider 92, an auxiliary spring 93, a sliding rod 94, a connecting rod 95, a friction plate 96, a first gear shaft 97, a first bevel gear 98, a second bevel gear 99 and a second gear shaft 910. The connecting head 91 is fixedly installed on the first gear shaft 97, and the sliding block 92 is slidably arranged on the connecting head 91. The two ends of the auxiliary spring 93 are respectively fixedly connected to the sliding block 92 and the connecting head 91. The sliding block 94 is fixedly installed on the bottom surface of the sliding block 92. The two ends of the connecting rod 95 are respectively fixedly connected to the sliding block 94 and the friction plate 96. 97 is rotatably arranged inside the channel steel plate 5 and fixedly connected to the connecting head 91. The first bevel gear 98 is fixedly connected to the first gear shaft 97, and the first gear shaft 97 is also meshed and transmitted with the second bevel gear 99. The two ends of the second gear shaft 910 are respectively fixedly connected to the threaded rod 83 and the second bevel gear 99. The second gear shaft 910 is rotatably connected to the channel steel plate 5. The connecting head 91 is provided with a hexagonal socket that cooperates with a hexagonal wrench. The shape of the slider 92 is consistent with the shape of the hexagonal socket. The friction plate 96 is annular in design, and the side of the friction plate 96 is also provided with friction patterns for enhancing friction. A sliding groove for cooperating with the connecting rod 95 is provided on the first gear shaft 97. The sliding rod 94 is slidably connected to the first gear shaft 97, and the sliding rod 94 is located in the internal cavity of the auxiliary spring 93. The sliding seat 81 is a mouth-shaped design, and the square nut 84 is located on the side wall of the inner cavity of the sliding seat 81. Such designs can improve the rigidity of such structures, thereby ensuring the stability of the overall device.

[0024] Working principle: First, select the model of the winch 1 according to the length and weight of the cable. Secondly, determine the position where the winch 1 needs to be installed in the distribution room. Finally, drill holes with an electric drill and fix the winch 1 with expansion bolts. Design the dragging route and the positions of the first pulley 3 and the second pulley 4. After selecting the matching pulleys, drive expansion bolts to fix the position of the first pulley 3. The second pulley 4 is hooked to the hanging ring 82 on the channel steel plate 5, and the channel steel plate 5 is also fixed with expansion bolts. The steel wire rope 2 on the winch 1 bypasses the first pulley 3 and the second pulley 4 and hangs down, and the lower end of the steel wire rope 2 is connected to the cable body 7 through the cable grommet 6. Personnel take their positions, start the winch 1 to tighten the steel wire rope 2. After confirming that there is no error, officially start the winch 1 to start dragging. The dragging process should be carried out slowly, and the gear position should not be too fast. During the dragging process, personnel should observe the winch 1, the first pulley 3, the second pulley 4, and the cable body 7 and other parts throughout the process. In case of an accident, immediately stop the operation. Drag the cable body 7 to the installation position, and repeat the above process to complete the laying of all cables in the distribution room.

[0025] When actually in use, when the position of the second pulley 4 needs to be adjusted, insert a hex wrench into the inside of the connector 91, squeeze the slider 92. The slider 92 is fixedly connected to the slide bar 94. The slide bar 94 and the friction plate 96 are fixedly connected through the connecting rod 95. Therefore, the friction plate 96 and the slider 92 will slide downward. The first gear shaft 97 rotatably connected to the channel steel plate 5 is also fixedly connected to the connector 91. A first bevel gear 98 meshing with the second bevel gear 99 is also fixed on the first gear shaft 97. The second bevel gear 99 is also fixedly connected to the threaded rod 83 through the second gear shaft 910. Therefore, when the hex wrench is inserted into the connector 91 to make the slider 92 slide downward, and then the connector 91 is rotated by the wrench, the threaded rod 83 will rotate synchronously under the transmission of structures such as the first bevel gear 98 and the second bevel gear 99. A square nut 84 and a hanging ring 82 hooked to the second pulley 4 are respectively fixed on the slide seat 81 sliding on the channel steel plate 5, and the square nut 84 is also threadedly connected to the threaded rod 83. Because after the threaded rod 83 rotates, it can drive the square nut 84 and the slide seat 81 to slide on the channel steel plate 5, thereby changing the position of the hanging ring 82 to achieve the adjustment of the position of the second pulley 4. After pulling out the hex wrench, the slider 92 loses its restraint, and under the action of the auxiliary spring 93 fixedly connected to the slider 92 and the connector 91 at both ends, the slider 92 slides upward, synchronously driving the friction plate 96 to slide upward until the friction plate 96 contacts the channel steel plate 5. At this time, a certain friction is formed between the friction lines on the friction plate 96 and the channel steel plate 5, thereby restricting the rotation of the friction plate 96. And a chute cooperating with the connecting rod 95 is provided on the first gear shaft 97. Under the action of this friction force, the first gear shaft 97 is synchronously restricted from rotating, and further the rotation of the threaded rod 83 is locked to limit the position of the hanging ring 82.

[0026] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
