Both the second upper and lower anti-slip pads abut against the support column 11. The second upper anti-slip pad increases the friction between the second upper pipe clamp 411 and the support column 11, and the second lower anti-slip pad increases the friction between the second lower pipe clamp 421 and the support column 11, thereby enhancing the connection strength between the second upper pipe clamp 411 and the support column 11 and between the second lower pipe clamp 421 and the support column 11. This allows the second frame 4 to adapt to supporting a second cable tray 5 with a greater weight. Specifically, the second lower anti-slip pad can be a rubber pad, but is not limited to this.

Specifically, the wider the width of the second bridge frame 5, the smaller the included angle between the second flat support rod 41 and the second inclined support rod 42; the farther the position of the second bridge frame 5 away from the support column 11, the smaller the included angle between the second flat support rod 41 and the second inclined support rod 42.
