The entire cable is covered with a highly insulating covering. They are mostly installed in the air or underground or underwater for telecommunications or power transmission. Twist is a very important criterion in measuring the quality of cables.

The broken cable may also accidentally injure the staff and endanger their safety. Utility Model Content

A threaded rod is rotatably connected to the upper side of the inner cavity of the I-shaped frame through a bearing. One end of the threaded rod passes through the I-shaped frame and extends to the outside of the I-shaped frame. The outer surface of the threaded rod is threadedly connected to a threaded sleeve.

[0022] Furthermore, in order to protect the cable during detection, slide grooves 10 are provided at the front and rear of the inner cavity of the detection frame 1. The opposite sides of the two slide grooves 10 are slidingly connected to the front and rear of the movable plate 2 through sliders respectively. The bottom of the inner cavity of the detection frame 1 is fixedly connected with an electric telescopic rod 9, which is electrically connected to the external power supply and controlled by a control switch. The telescopic end of the electric telescopic rod 9 is fixedly connected to the bottom of the movable plate 2, and support rods 11 are fixedly connected on all four sides of the top of the movable plate 2. The tops of the four support rods 11 are fixedly connected with protective plates 8.

[0023] When in use, the two ends of the cable are respectively passed through the limiting holes 77 on the two I-frames 71 for bending. By rotating the threaded rod 72, the threaded rod 72 will drive the threaded sleeve 73 to move, and the threaded sleeve 73 will drive the limiting plate 76 to move toward the limiting hole 77 through the sliding plate 75, so that the limiting plate 76 squeezes and limits the cable passing through the limiting hole 77, and the cable is installed on the two I-frames 71. By controlling the electric telescopic rod 9 to retract, the electric telescopic rod 9 drives the movable plate 2 to move downward, and the cable on the I-frame 71 is moved into the detection frame 1.

[0024] After testing the cable, stop the rotation of the rotating rod 5 and control the electric telescopic rod 9 to extend, so that the electric telescopic rod 9 drives the movable plate 2 to move upward and reset, so that the cable on the movable plate 2 is exposed. By rotating the threaded rod 72 in the opposite direction, the threaded rod 72 drives the limiting plate 76 to move in the opposite direction and no longer squeezes the cable in the limiting hole 77, so that the cable can be taken out and replaced.
