A plurality of U-shaped bolts 52 are arranged on the stabilizing rod 5, and a plurality of through holes 51 are opened in the length direction of the stabilizing rod 5. The U-shaped bolts 52 are buckled on the side wall of the vertical pole 1 and pass through the stabilizing rod 5, so that the two ends of the U-shaped bolts 52 are threadedly connected to the nuts to fix the stabilizing rod 5. In this embodiment, three stabilizing rods 5 are arranged, and at least one is arranged in the middle position of the vertical pole 1. Since a plurality of through holes 51 are arranged, the distance between the two vertical poles 1 can be adjusted according to the width of the window 6, and the installation has stronger adaptability.
