When the limiter is used, the fixing The fixed ring 6 clamps the cable, and the above devices cooperate with each other to form the basic structure of the limiter. At the same time, the bolts 12 and the nuts 11 are used to change the distance between the two reinforcement plates 1. By changing the expansion range between the four flat plates 17, the effect of fixing the limiter is achieved. The surface of the reinforcement plate 1 is provided with a slot 5. When the limiter is used, the nut 11 and the bolt 12 are both located inside the slot 5. The slot 5 improves the stability of the adjustment component 4 when it is in action. The surface of the reinforcement plate 1 is fixedly connected with an isolation cover 8, and the slot 5 is located inside the isolation cover 8. The isolation cover 8 prevents the adjustment component 4 from wearing the inner wall of the cable tube.

[0025] A contour pad 7 is fixedly connected to one side of the reinforcement frame 3 away from the flat plate 17. When the limiter is used, the contour pad 7 is in close contact with the inside of the cable tube. A plurality of ventilation grooves 10 are provided on the surface of the contour pad 7. The ventilation grooves 10 run through the upper and lower surfaces of the contour pad 7. The ventilation grooves 10 improve the heat dissipation effect. A reinforcement suction cup 9 is fixedly connected to one side of the isolation cover 8 away from the reinforcement plate 1.
