[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-4The utility model provides an embodiment: comprising a connecting device body 1 and a cable body 20, the bottom end of the connecting device body 1 is fixedly connected to the supporting leg 2, the bottom end of the supporting leg 2 is fixedly connected to the bottom plate 3, a slide rail 7 is arranged on the top of the connecting device body 1, a slider 8 is slidably connected inside the slide rail 7, the slider 8 is fixedly connected to the movable block 4, the top surface of the movable block 4 is fixedly connected to the connecting block 5, one side of the connecting block 5 is fixedly connected to the clamping member 6, one side of the clamping member 6 is fixedly connected to the extruding member 9, a spring 19 is arranged inside the extruding member 9, and the top of the extruding member 9 is fixedly connected to the limit block 1 8. The slider 8 is slidably connected to the limit plate 17, and the middle part of the limit plate 17 is fixedly connected to the connection block 3 16. The end of the connection block 3 16 away from the limit plate 17 is fixedly connected to the pipe clamp 10. The movable block 14 has a slide rail 2 11 on one side of the inclined surface. The slide rail 2 11 is slidably connected to the movable block 2 12. The middle part of the bottom surface of the movable block 2 12 is fixedly connected to the connection block 2 13. The middle part of the bottom surface of the connection block 2 13 is rotatably connected to the threaded rod 14. The threaded rod 14 is threadedly connected to the middle part of the bottom surface of the connecting device body 1, and the end of the threaded rod 14 away from the connection block 2 13 is fixedly connected to the adjusting knob 15.

[0028] The cable body 20 is clamped in the pipe clamp 10, and the pressure relief member 21 is fixedly connected in the cable body 20. The pressure relief member 21 is fixedly connected to the protective pad 22. The protective pad 22 is provided with a cable core 23, which effectively reinforces the structure of the cable body 20 and effectively prevents the cable body 20 from breaking. The clamping member 6 is symmetrically arranged in two groups, and the connecting device body 1 is parallelly arranged in two groups, so that the cable body 20 is straightened to prevent breaking. The pipe clamp 10 on the clamping member 6 effectively clamps the cable body 20, and one end of the spring 19 abuts against one side of the clamping member 6, and the other end of the spring 19 abuts against the limit plate 17, so that the spring 19 effectively limits the limit plate 17. The plate 17 is squeezed so that the pipe clamp 10 at the front end of the connecting block three 16 fixedly connected to the limit plate 17 tightly clamps the cable body 20. The protective pad 22 is made of rubber material, which effectively protects the cable core 23 in the protective pad 22. The length between the bottom surface of the connecting device body 1 and the bottom plate 3 is greater than the length of the threaded rod 14, so that the threaded rod 14 can be more conveniently moved in the connecting device body 1. There are two groups of extrusion members 9 on the clamping member 6, which are distributed on the upper and lower parts of one side of the extrusion member 9, which have a better clamping effect on the cable body 20 and prevent the cable body 20 from falling off from the pipe clamp 10 and causing the cable body 20 to break.

[0029] Working principle: Rotate the adjusting knob 15, the adjusting knob 15 drives the fixedly connected threaded rod 14 to move relative to the bottom surface of the connecting device body 1 through the thread, so that the threaded rod 14 drives the connecting block 2 13 to move up and down, and the movable block 2 12 fixedly connected to the top of the connecting block 2 13 slides in the slide rail 2 11 in the movable block 1 4. Since the slide rail 2 11 limits the lateral position of the movable block 1 4, the movable block 1 4 slides up and down with the movable block 2 12 and slides left and right in the connecting device body 1 to clamp the cable body 20. When the cable body 20 is clamped The extrusion piece 9 on one side of the clamping piece 6 fixedly connected to the top surface of the movable block 4 and the connecting block 5 squeezes the connecting block 3 16 on the limiting plate 17 inside it, and the connecting block 3 16 squeezes the tube clamp 10, and the tube clamp 10 clamps the cable body 20 more firmly. The two sets of parallel connecting device bodies 1 straighten the cable body 20 to prevent the cable body 20 from bending. When squeezing the cable body 20, the decompression piece 21 inside the cable body 20 decompresses to prevent the cable core 23 in the protective pad 22 from being damaged by the cable body 20 due to excessive pressure.
