The movable plate 7 is located on the side of the connecting plate 5 away from the vertical plate 10. One end of the movable plate 7 extends horizontally between the two connecting plates 5 toward the fixed plate 4. The movable plate 7 is fixed to an end close to the fixed plate 4 with a vertical plate 11 extending horizontally toward the vertical plate 10. The end of the vertical plate 11 away from the movable plate 7 is fixed with a first sealing strip 9. The end of the connecting plate 5 located on the side of the vertical plate 11 away from the fixed plate 4 is provided with a second sealing strip 6. The first sealing strip 9 and the second sealing strip 6 are respectively fitted with the vertical plate 10 and the movable plate 7.

[0018] By providing a positioning plate 8 between the vertical plate 10 and the accordion strip 2, and by affixing the positioning plate 8 to the side wall of one of the aluminum curtain walls 3 facing the vertical plate 10, and by securing the vertical plate 10 to one of the aluminum curtain walls 3 via the positioning plate 8, the positioning plate 8 can improve the stability of the device during use and prevent the vertical plate 10 from shifting during use. By aligning the fixed plate 4 with the side wall of the movable plate 7 away from the accordion strip 2, aligning the end of the vertical plate 11 away from the vertical plate 10 with the side wall of the movable plate 7 away from the accordion strip 2, and aligning the end of the connecting plate 5 on the side of the vertical plate 11 away from the movable plate 7 away from the vertical plate 10 with the side wall of the movable plate 7 away from the accordion strip 2, the overall outer surface of the device can be flattened, improving the aesthetics of the device during use.
