The roller 10 above the second fixed plate 6 is in contact with the cable 11. The upper inner sides of the left and right clamps 1 and 2 are fixedly connected with a friction pad 12, and the lower end surface of the friction pad 12 is in close contact with the steel cable 13. In this way, the left and right clamps 1 and 2 can be used to effectively fix the steel cable 13 and the cable 11, and the switching of the friction pad 12 and the roller 10 can make the overall fixed anti-loosening device convenient to move and adjust. , solves the problem that the traditional suspended anti-loosening power fittings are not flexible enough in adjusting the position. The lower end face of the connecting plate 3 located at the lower left is fixedly connected with an operating panel 14, and the lower end face of the operating panel 14 is fixedly connected with a guide block 15. The upper inner side of the guide block 15 is fixedly connected with a threaded block 16, and the upper end face of the threaded block 16 is fixedly connected to the lower end face of the operating panel 14. In this way, the spiral connection between the external extended threaded rod and the threaded block 16 can be utilized to make the movement of the overall device more stable, further improving the convenience of the cable 11 anti-loosening operation. The guide block 15 is arranged in a trumpet shape, and the cross-sectional diameter of the threaded block 16 is smaller than the width of the operating panel 14, which can facilitate the guiding operation of the external extended threaded rod. The thickness of the friction pad 12 is 5 mm, and the friction pad 12 is arranged in an arc shape, so that the contact between the friction pad 12 and the steel cable 13 can be closer.

[0027] Working process: when the cable 11 needs to be connected and fixed with the steel cable 13 to achieve the anti-loosening function, first place the cable 11 and the steel cable 13 on the inner side of the left clamp 1, and then assemble the right clamp 2 on the left clamp 1. At this time, the first fixing plate 5 and the second fixing plate 6 are engaged with the first card slot 7 and the second card slot 8, and then the connecting bolts 4 are used to effectively connect the connecting plates 3. At the same time, the cable 11 is tightly pressed against the roller 10 below under the action of gravity. At this time, the left clamp 1 and the right clamp 2 will also fall downward, thereby driving the friction pad 12 to fit the steel cable 13 tightly, so that the whole device maintains a stable state. When the season changes, the cable 11 When the steel cable 13 expands and contracts due to heat and cold, and the position of the entire device needs to be adjusted, the technician first uses the extended top threaded extension rod to reach the inner side of the guide block 15, and then twists the extended threaded rod. At this time, the extended threaded rod is spirally connected to the threaded block 16, and then the extended threaded rod is pushed upward. At this time, under the action of the upward thrust, the friction pad 12 is separated from the contact with the steel cable 13. At this time, the rollers 10 on the two support plates 9 are respectively in contact with the steel cable 13 and the cable 11, and then the entire device is pushed to move with the assistance of the rollers 10. When it moves to the appropriate position, the extended threaded rod is loosened and unscrewed. At this time, the position adjustment of the cable to prevent loosening can be completed.
