[0007] Furthermore, a limiting block 1 is installed at the bottom end of the screw rod.

[0008] Furthermore, a circular groove is provided at the top end of the sleeve rod on the periphery of the slide groove, and a limiting block 2 is movably connected in the circular groove. A connecting block is installed at the top end of the limiting block 2, and the top end of the connecting block is connected to the bottom end of the adjusting hand wheel.

[0009] Furthermore, heat dissipation grooves are provided on the surfaces of the bridge frame 1 and the bridge frame 2.

[0010] Furthermore, the surfaces of the bridge frame 1 and the bridge frame 2 are both provided with a galvanized layer.

[0011] Furthermore, the screw rod is threadably connected to the adjusting hand wheel.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By using the adjusting handwheel in coordination with the screw rod, first turn the adjusting handwheel, and the adjusting handwheel is connected to the screw rod through a thread, so that when the adjusting handwheel turns, it drives the screw rod to move into or out of the slide groove, thereby driving the second bridge to rotate, and then the angle between the first bridge and the second bridge can be adjusted and the angle can be fixed, which saves time and effort and improves work efficiency.
