A rectangular cavity 8 is opened at the bottom of the inner cavity of the lifting seat 3, and a slidable clamping block 10 is set in the inner cavity of the rectangular cavity 8. An electric push rod 9 is fixedly installed at the bottom of the lifting seat 3. The output end of the electric push rod 9 passes through the inner cavity of the rectangular cavity 8 and is fixedly connected to the bottom of the clamping block 10. The top of 10 is provided with an arc-shaped concave surface adapted to the limiting pulley 65. The setting of the electric push rod 9 promotes the clamping block 10. At the same time, with the cooperation of the rectangular cavity 8 and the limiting pulley 65, the cable is squeezed and limited, thereby stopping the wire release to prevent the cable on the right side from sliding out by itself during the process of tightening the cable. The inner cavity of the support frame 2 is provided with a tightening component 6, and the tightening component 6 includes a threaded lifting rod 61 rotatably connected to the top of the inner cavity of the support frame 2 through a bearing. The surface of the threaded lifting rod 61 is threadedly connected to a threaded sliding seat 62. The front and rear ends of both sides of the threaded slide 62 are fixedly connected to the limit slider 11, and the front and rear ends of both sides of the inner cavity of the supporting frame 2 are provided with limit slide grooves 12 adapted to the limit slider 11. The front side of the threaded slide 62 is fixedly connected to the lifting seat 3, and a stepper motor 63 is fixedly installed on the left side of the bottom of the load-bearing trailer 1. The bottom end of the threaded lifting rod 61 penetrates to the bottom of the load-bearing trailer 1 and is fixedly connected to the output shaft of the stepper motor 63.

[0024] Working principle: When the utility model is used, the user lays the cable by pulling the left end of the cable. When the cable is laid, the cable located on the surface of the cable drum 5 passes through the inner cavity of the lifting seat 3 and continues to be laid. After the laying is completed, the leftmost end of the cable is fixed by the cable fixing clamp, and then the electric push rod 9 and the stepper motor 63 are turned on. The electric push rod 9 pushes the clamping block 10 upward to slide. The clamping block 10 rises upward from the inner cavity of the rectangular cavity 8 and engages on the surface of the cable to clamp and limit the cable. Then the stepper motor 63 drives the threaded lifting rod 61 to rotate in the inner cavity of the support frame 2. During the rotation, the threaded lifting rod 61 pushes the threaded sliding seat 62 through its surface thread, so that the lifting seat 3 drives the cable to slide downward. During the downward process of the cable, the support pulley 64 blocks the cable, so that the cable can be tightened downward, thereby tightening the bending position of the cable. At the same time, the user fixes the tightened cable position in turn, and finally cuts the cable.

[0025] In summary: the cable tightening device for cable laying, through the coordinated use of the carrying trailer 1, the support arm 4 and the cable drum 5, the cable is paid out, and the cable is clamped and positioned through the coordinated use of the electric push rod 9 and the clamping block 10. Then, with the coordinated use of the support frame 2 and the tightening assembly 6, the cable located on the left side of the support frame 2 is pulled down and tightened, thereby achieving the purpose of automatically tightening the cable and saving effort and being efficient in operation.
