[0034] See also Figure 4The positioning assembly 4 includes a rotating seat 42 rotatably connected to the top of the adjustment assembly 2, a rotating shaft 41 is provided on the lower surface of the rotating seat 42, and the rotating shaft 41 is rotatably connected to the inside of the rotating groove 26, and a telescopic rod 43 and a first spring 44 are respectively installed inside the rotating seat 42, and the first spring 44 is located outside the telescopic rod 43, and a connecting plate 45 is installed on the top of the telescopic rod 43 and the first spring 44, and a positioning rod 46 is connected inside the connecting plate 45, and the positioning rod 46 and the positioning groove 36 are a snap-fit ​​structure, and a pull plate 47 is installed on the top of the positioning rod 46, and a pull ring 48 is installed on the top of the pull plate 47, and a second spring 49 is installed on the top of the connecting plate 45, and the second spring 49 is located outside the positioning rod 46, and one end of the second spring 49 is connected to the pull plate 47;

[0035] The rotating seat 42 is rotatably connected to the top of the adjustment component 2 through the setting of the rotating groove 26 and the rotating shaft 41. The setting of the telescopic rod 43 and the first spring 44 allows the connecting plate 45 to be adjusted according to the height of the threaded rod 32, so that the positioning rod 46 is located inside the positioning groove 36 to fix the adjustment ring plate 33.

[0036] The implementation principle of this embodiment is: the cable device 1 is the existing structure in the publication number CN220364862U, which includes: a main frame plate, a sleeve plate, a protective ring frame, a protective cover, and a cable body; the specific implementation method is not described in detail here;

[0037] When using the adjustment component 2, it is first necessary to confirm that the expected adjustment degree is high. After confirmation, the hydraulic rod 23 can be used to perform corresponding adjustment processing. During the adjustment process, the output end of the hydraulic rod 23 needs to be adjusted first. The output end of the hydraulic rod 23 will be displaced upward. Similarly, the adjustment shaft plate 24 will be displaced along with the hydraulic rod 23. The output end of the hydraulic rod 23 will continue to move until the adjustment shaft plate 24 moves to the expected adjustment degree. The adjustment process can be stopped. After stopping the adjustment process, the adjustment shaft plate 24 can be used to perform corresponding angle fine-tuning processing. When performing angle fine-tuning, it is necessary to push the adjustment shaft plate 24 to continue the expected adjustment angle.

[0038] When using the maintenance and inspection component 3, it is first necessary to use the adjustment component 2 to perform the corresponding height adjustment processing. After the adjustment is completed, the maintenance and inspection component 3 can be used to perform the corresponding maintenance and inspection positioning processing. When performing the maintenance and inspection positioning, it is first necessary to confirm the expected positioning position, and then hold the adjustment ring plate 33 and rotate the adjustment ring plate 33 toward the expected positioning position. During the rotation process, the adjustment ring plate 33 will drive the threaded rod 32 to transmit. Similarly, the linkage frame plate 34 connected to the threaded rod 32 will move with it. Continue to rotate the adjustment ring plate 33 until the inner surface of the limiting semi-ring plate 35 is attached to the expected positioning position, then stop rotating the adjustment ring plate 33, and then according to the above operation content, perform synchronous adjustment processing on the adjustment ring plate 33 on the other side;

[0039] When the adjustment ring plate 33 is used, in order to prevent the adjustment ring plate 33 from rotating or accidentally hitting, the user can position the adjustment ring plate 33 through the positioning assembly 4; the user pulls the connecting plate 45 upwards through the setting of the telescopic rod 43 and the first spring 44 to move the connecting plate 45 to a suitable position, and then rotates the rotating seat 42 to move the connecting plate 45 to the position of the adjustment ring plate 33, and then holds the pull ring 48 and pulls it upwards, and the pull ring 48 drives the positioning rod 46 to move through the pull plate 47, and the positioning rod 46 is located at the through hole in the connecting plate 45 and moves, and the second spring 49 is in an elongated state. After the positioning rod 46 is located in the positioning groove 36 at a suitable position, the user releases the pull ring 48, and the positioning rod 46 is located in the suitable positioning groove 36 through the setting of the second spring 49. At this time, the adjustment ring plate 33 can be fixed;

[0040] When the user needs to use the adjustment ring plate 33, the user pulls the pull ring 48 upwards to disengage the positioning rod 46 from the positioning groove 36, and then rotates the rotating seat 42 to rotate the connecting plate 45 to the other side of the maintenance component 3 to avoid affecting the use of the maintenance component 3.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
