When the hook body 1 is hung on the cable 100, the first clamping fixture 2 and the second clamping fixture 3 can both rotate into the hook groove 13 of the hook body 1, and the first clamping fixture 2 and the second clamping fixture 3 can form a clamping space 200 for clamping the cable 100 in the hook groove 13 of the hook body 1; in this solution, the first clamping fixture 2 and the second clamping fixture 3 are both metal parts. When the device is hung down from above the cable 100, the first clamping fixture 2 can be resisted by the cable 100 and rotate upward. An elastic part can be provided at the rotating shaft of the second clamping fixture 3, so that the second clamping fixture 3 will have an upward flipping effect. At this time, the cable 100 can be clamped between the first clamping fixture 2 and the second clamping fixture 3.

[0025] In the specific implementation manner, reference Figures 1 to 5 The middle part of the first clamping member 2 is bent to form a first clamping groove 21, and a "human" shaped first clamping piece 22 is installed in the first clamping groove 21; both ends of the first clamping member 2 are provided with a first slide groove 23 connected to the first clamping groove 21, and a slider 24 is slidably installed in the first slide groove 23. The two ends of the first clamping piece 22 extend from the first clamping groove 21 to the first slide groove 23 and are connected to the slider 24. The slider 24 is connected to a first tension spring 2 between the first slide groove 23 and the end of the first clamping member 2. 5. In this solution, when the cable 100 is clamped by the first clamping member 2 and the second clamping member 3, the cable 100 will come into contact with the first clip 22 and squeeze the first clip 22. After the first clip 22 is subjected to the force, it will move toward the top of the first clamping groove 21, and the two ends of the first clip 22 will shrink close to each other. At this time, the first clip 22 will apply tension to the first tension spring 25, and the first tension spring 25 will tighten the first clip 22, so that the first clip 22 can exert a tightening effect on the cable 100.

[0026] In the specific implementation manner, reference Figure 2 、 Figure 3The middle part of the first clamping fixture 2 is rotatably connected to the hook end 11 of the hook body 1.
