The other end of the pull rope 28 is fixedly connected with an insulator string 32 through a rope clamp 31. The other end of the pull rope 28 is fixedly provided with a rope clamp 31 and a threaded rod 30 in sequence. In the present embodiment, the rope clip 31 is provided with a first rope hole and a second rope hole. The first cord hole is in an interference fit with the pull cord 28. The other end of the pull cord 28 passes through the first cord hole and is fixedly connected with the cord clip 31. The second cord hole is in clearance fit with the pull cord 28. The other end of the pull rope 28 is fixed by the following steps: the other end of the pull cord 28 is passed around the string 32, through the second cord hole, and then the lock nut 29 is fitted with the threaded rod 30, and the lock nut 29 abuts against the other end of the cord clip 31 remote from the string 32. Wherein the outer diameter of the lock nut 29 is larger than the aperture of the second through hole.

The side of the engagement slider 36 facing the other end of the pull cord 28 has an inclined guide surface.

The installation flow and the use principle of the damper device of the embodiment are as follows: wrapping the elastic leather sheath 1 outside the cable; then the half-arc jacket is sleeved outside the elastic leather sheath 1 to form a fixed jacket; and then the two limiting semi-rings are locked by the fastening assembly. In the fastening assembly, the axial direction of the bolt is parallel to the axial direction of the limiting ring, so that the axial stress direction of the bolt is different from the expansion direction of the limiting ring, and the bolt is not easy to loosen.

Then, the positioning slider is pushed downward (the two stopper ring assemblies are pushed inward), so that the two stopper ring assemblies push the stopper column unit to move toward the inside of the fixing jacket until the eight locking sliders 6 clamp the cable through the elastic leather sheath 1. Due to the special structure of the V-shaped groove of the fastening slot, the fastening clamping block 20 can compress the elastic connection unit 21 to retract towards the fastening sliding groove 18 under the guiding action of the second side surface in the process that the limiting sliding block 10 pushes the limiting column 8 to move. However, since the first side is perpendicular to the length direction of the limit slot, when the limit post 8 pushes the limit slider 10 to the outside, the fastening block 20 cannot retract toward the fastening chute 18.

After the eight locking sliding blocks 6 clamp the cable through the elastic leather sheath 1, the other end of the pull rope 28 bypasses the insulator string 32 and then passes through the second through hole, and finally is matched and locked with the threaded rod 30 through the locking nut 29. When the damper device is to be shifted away from the insulator string 32, the pull rope 28 needs to be elongated, so that the positioning slide block 26 moves downward, and further, the two limiting ring assemblies push the limiting columns 8 to move inward, thereby improving the clamping force of the locking slide block 6 on the cable, and forming self-locking.

In summary, the present invention is a specific application example, and the protection scope of the present invention is not limited, and the technical scheme of adopting equivalent substitution falls within the protection scope of the present invention.
