Common lifting devices are complex in structure and inconvenient to operate, and it is difficult to meet the needs of different working scenarios and cable specifications. Many devices lack precise control functions, resulting in an unstable lifting process, which can easily cause the cable to shake and be damaged. Moreover, when traditional lifting devices are used to fix and clamp cables, it is either difficult to ensure the firmness of the clamping, or it is easy to damage the insulation layer or internal structure of the cable due to excessive clamping.

When the electric telescopic rod is extended to the maximum length, it means that the cable body on the retractable rod has been fully released, and the intelligent control panel can accurately obtain this information. In summary, the user can accurately judge the remaining amount of the cable body according to the extended length of the electric telescopic rod. When the cable body is fully released, the intelligent control panel will control the electric telescopic rod, the pressure sensor and the second motor to stop working, which brings great convenience to the user.

At the same time, with the perfect cooperation between the slide rail 12 and the slider 17, the stability and smoothness of the nut 11 during the lifting process can be effectively guaranteed, thereby realizing accurate and stable lifting operation of the cable body 3, which greatly provides convenience for the user.

[0038] The fixing mechanism includes two clamping blocks 2, two screw rods 13, two threaded barrels 18, two cushions 19, two threaded rods 37 and four connecting plates 15. The four connecting plates 15 are detachably connected to the left and right sides of the two clamping blocks 2, the two threaded barrels 18 are detachably connected to the bottom of the two connecting plates 15 located below, the two cushions 19 are detachably connected to the opposite sides of the two clamping blocks 2, the two threaded rods 37 are threadedly connected to the two threaded barrels 18, the two threaded rods 37 penetrate two adjacent connecting plates 15, and the rear end of the clamping block 2 located below is detachably connected to the front end of the connecting block 10.

The rubber box 33 will also be subjected to force accordingly, and the telescopic spring 32 will shrink due to the force, so that the pressure sensor 35 can keenly sense the change in pressure. As the cable body 3 is continuously released, the force exerted on the abutment plate 34 will gradually decrease, and when the telescopic spring 32 and the rubber box 33 are no longer under force, they will quickly recover. At this time, the pressure sensor 35 cannot feel the pressure, and will promptly feed back this information to the intelligent control panel 9, which in turn controls the extension of the electric telescopic rod 28.
