[0002] Wires and cables are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors; When performing fault detection on a cable, it is necessary to connect the detection equipment to the cable through a signal connecting line and send a pulse signal to the cable to achieve the purpose of detection. When detecting underground cables and connecting the signal connecting line to the cable through a clamp, the distance between the cable and the signal connecting line and the ground is low, and the tension of the connecting line is relatively loose during detection, which may easily cause the connector of the connecting line to contact the soil on the ground during detection.

[0014] The present invention has the following beneficial effects: 1. According to the present invention, when the staff rotates the multiple long rods, the rotation of the multiple long rods will rotate to the outside of the main body, and then when the multiple long rods are rotating, the sliding plates on the long rods will be pushed by the pushing plates to slide on the surfaces of the multiple long rods, and when the sliding plates slide, they will drive the sliding ring 1 to slide forward synchronously, and when the sliding ring 1 slides, it will drive the two drag chains to rotate on the gear shaft and drive the sliding ring 2 to slide in the direction of the sliding ring 1, and when the sliding ring 2 slides, it will pull the fixed ring through the two long plates 2, and when the fixed ring is pulled by the two long plates 2, it will squeeze the curved tube, and at the same time, when the fixed ring slides, it will push the rotating plate 2 to rotate outwards through the multiple rotating plates, and when the multiple rotating plates 2 rotate outwards, they will block the signal connecting line and the ground, thereby reducing the situation where the signal connecting line contacts the ground soil when the signal connecting line is connected to the cable for detection, thereby reducing the influence of the soil on the propagation of the pulse signal and improving the detection accuracy.

[0015] 2. According to the present invention, when the two drag chains drive the sliding ring 2 to slide, the sliding of the sliding ring 2 will pass through the long groove on the outer cylinder through the inner wall of the plug rod to slide in the threaded groove on the outer surface of the threaded rod; when the sliding ring 2 drives the internal plug rod to slide in the threaded groove on the outer surface of the threaded rod and drives the threaded rod to move, when the threaded rod rotates, it will drive the C-type limit frame to rotate synchronously; when the C-type limit frame rotates, it will drive the signal connection line passed through to rotate on the surface of the outer cylinder; when the C-type limit frame drives the signal connection line to rotate as the threaded rod rotates, the signal connection line will be entangled on the two outer cylinders and shortened, thereby reducing the situation where the signal connection line is accidentally pulled and dragged during detection due to its excessive length, and reducing the situation where the connection is loose and the signal is interrupted due to accidental pulling of the cable during the detection process, thereby improving the stability and reliability during detection.

[0016] 3. According to the present invention, when the second long plate drives the fixed ring to slide, the sliding of the fixed ring will push the multiple curved tubes to slide. When the multiple curved tubes are pushed by the fixed ring, they will drive the connecting ears to slide inside the arc groove. When the multiple connecting ears slide, they will drive the rotating cylinder to rotate. When the rotating cylinder rotates, the annular serrated groove provided on its inner wall will push the L rod to slide inside the annular serrated groove. It should be noted that when the annular serrated groove rotates with the rotating cylinder, the arc path portion on the annular serrated groove will push the multiple L rods to slide forward. When the multiple L rods slide, they will push the connecting disk to slide synchronously. When the connecting disk slides, the multiple spring telescopic rods will be stretched. Then, when the connecting disk slides, it will drive the hollow shaft and the sliding sleeve to slide synchronously. At this time, the connecting line will push the sliding sleeve inside the hollow shaft when the hollow shaft slides. At this time, the multiple sliding balls inside the sliding sleeve will be separated from the inner wall of the hollow shaft. Then, when the multiple connecting ears slide to the bottom of the arc groove, they will drive the rotating cylinder to rotate. The sliding sleeve is moved to make the part of the path between the annular serrated grooves inside it correspond to the L rod. At this time, the multiple stretched spring telescopic rods will drive the connecting disk to reset. When the connecting disk is reset, it will drive the hollow shaft to reset on the surface of the signal connecting line. When the hollow shaft is reset on the surface of the connecting line, the stretching spring on the sliding sleeve will push the sliding sleeve to reset. At this time, the multiple sliding balls inside the sliding sleeve will be squeezed by the inner wall of the hollow shaft and mounted on the surface of the connecting line. Subsequently, when the connecting disk is reset, part of the connecting line will be driven to be recovered to the inside of the rotating cylinder. When the signal connecting line is accidentally pulled during the detection process, the part of the connecting line recovered inside the rotating cylinder can slide outward when being pulled, thereby effectively reducing the situation where the cable is broken or damaged due to excessive pulling. At the same time, when the length of the connecting line needs to be adjusted, the part of the connecting line that is recovered can be easily pulled out to achieve the effect of adjusting the length of the connecting line, which can reduce damage caused by accidental pulling and improve the flexibility and practicality of the device.

When working, the main body 1 will generate a pulse signal and flow through the signal connection line inside the cable to be tested; S3: Signal detection: When the pulse signal encounters a fault point in the cable, it will return to the main body 1 to achieve the purpose of detection.

It should be noted that when the annular serrated groove 603 rotates with the rotating cylinder 602, the L rod 604 will slide inside the annular serrated groove 603. When the connecting plate 701 slides, the multiple spring telescopic rods 703 are stretched, and then the connecting plate 701 slides, which drives the hollow shaft 702 and the sliding sleeve 704 to slide synchronously. At this time, the connecting line pushes the sliding sleeve 704 inside the hollow shaft 702 when the hollow shaft 702 slides. At this time, the multiple sliding balls inside the sliding sleeve 704 are separated from the inner wall of the hollow shaft 702. Then, when the multiple connecting ears 6 When the rotating cylinder 602 slides to the bottom of the arc groove 305, it will drive the rotating cylinder 602 to rotate and make the part of the path between the annular sawtooth groove 603 inside it correspond to the L rod 604. At this time, the multiple stretched spring telescopic rods 703 will drive the connecting disk 701 to reset. When the connecting disk 701 is reset, it will drive the hollow shaft 702 to reset on the surface of the signal connecting line. When the hollow shaft 702 is reset on the surface of the connecting line, the stretch spring on the sliding sleeve 704 will push the sliding sleeve 704 to reset. At this time, the multiple sliding balls inside the sliding sleeve 704 will be squeezed by the inner wall of the hollow shaft 702. The surface of the connecting wire is framed, and then when the connecting disk 701 is reset, part of the connecting wire will be driven to be recovered into the inside of the rotating cylinder 602. When the signal connecting wire is accidentally pulled during the detection process, the part of the connecting wire recovered inside the rotating cylinder 602 can slide outward when pulled, thereby effectively reducing the possibility of cable breakage or damage due to excessive pulling. At the same time, when the length of the connecting wire needs to be adjusted, the part of the recovered connecting wire can be easily pulled out to achieve the effect of adjusting the length of the connecting wire, which reduces damage caused by accidental pulling and improves the flexibility and practicality of the device.
