See Fig. 2 Fig. 3 As shown, an elongated hole 9 is provided at the lower end of the suspension rod 6 of the present invention. 10 is a gasket.

[0025] In its specific design, the utility model is suspended from the ceiling to provide vibration reduction for the cables. Multiple cables are laid perpendicular to the length of the tie plate 1 and securely fastened to the tie plate 1. Multiple tie plates are arranged along the cable axis to achieve this vibration reduction effect. The tie plate 1 is provided with multiple cable tie holes, and the upper portion is connected to the right outer frame 7 with countersunk screws to prevent interference with the cables.
