The driving assembly 100 is used for providing power, specifically, the driving assembly 100 may adopt a hydraulic cylinder, a piston rod is disposed inside the driving assembly 100, the piston rod can be controlled to be pushed out by injecting high-pressure hydraulic oil into the hydraulic cylinder, and at this time, when the plug assembly 200 is connected to the movable end of the piston rod, the plug assembly 200 can be controlled to push the cable to bend. Of course, when a hydraulic cylinder is used, an external hydraulic pump is required. The drive assembly 100 has a mounting portion 110 thereon to facilitate connection of the drive assembly 100 to the adjustable support bar 300. In this way, the driving assembly 100 can be fixed by only fixing the adjustable support bar 300, thereby overcoming the reaction force generated when pushing the cable.

The adjustable support bar 300 has at least one adjustment structure 320 capable of changing the position of a support base 310 along the length of the adjustable support bar 300. The adjustable support rod 300 is arranged between two planes, so that the support seats 310 at two ends are in contact with the planes, and then the positions of the support seats 310 are further adjusted by the adjusting structure 320, so that the support seats 310 move outwards along the length direction of the adjustable support rod 300, and the pressure applied by the support seats 310 to the planes is increased, so that the adjustable support rod 300 can be clamped between the two planes for fixing. The fixing mode has low requirements on environment and is very easy to fix. In the prior art, the fixing mode needs to use a bracket for laying the cable as a fixing point or to temporarily reinforce a fixing point on the inner wall of the cable tunnel, which is time-consuming and labor-consuming.

The vertical serpentine arrangement, i.e. the cable is bent in a vertical space, the plane in which the cable lies is vertical. Referring to fig. 2, the adjustable support rod 300 may be horizontally disposed in the cable tunnel, and the support bases 310 at two ends respectively abut against two sidewalls of the cable tunnel to fix the adjustable support rod 300. At this time, the installation portion 110 of the driving assembly 100 is connected with the shaft of the adjustable support rod 300, so that the driving assembly 100 is vertically arranged above the position where the cable needs to be bent, the driving assembly 100 drives the top assembly 200 to move downwards, contact the cable and continuously press down, and the cable can be bent to a required radian.
