[0023] By rotating the two clamping plates 1 towards each other so that the two are spliced ​​into a complete ring, the lining kit 6 on the inner side of the clamping plate 1 clamps the cable, and then the two movable hanging plates 3 are installed on the hanging bracket through the fasteners 5. When the hanging height of the clamping plate 1 needs to be adjusted, the position of the clamping plate 1 can be adjusted by sliding the cover plate 2 upward or downward, thereby realizing the adjustment of the hanging height of the clamping plate 1, so that the overall suspension wire clamp is suitable for different application scenarios, which greatly improves the versatility of the overall suspension wire clamp; in addition, the connection between the cover plate 2 and the movable hanging plate 3 not only does not increase the overall weight, but also does not need to use the U-bolts in the prior art to fix the cables, which greatly reduces the bearing pressure of the hanging bracket,

[0024] Reference Figure 2 The positioning member 4 includes a screw rod 41, one end of which penetrates the bottom end of the movable hanging plate 3 and extends to the outside of the sleeve plate 2. The screw rod 41 is rotatably connected to the movable hanging plate 3. The threaded end of the screw rod 41 is threadedly connected with a nut 42. Both sides of the sleeve plate 2 are provided with a slide groove 43. The screw rod 41 penetrates the slide groove 43 and is slidably connected to the inner wall of the slide groove 43. By tightening the nut 42 to make it contact with the outer wall of the sleeve plate 2, the clamping plate 1 and the sleeve plate 2 are kept fixed, so that the clamping plate 1 is kept at a corresponding hanging height.
