An airbag 12 is arranged on the cross bar 13. The airbag 12 is sleeved on the cross bar 13. When the slider 16 moves towards the position of the airbag 12, it will compress the airbag 12. When the airbag 12 is compressed, the gas inside will flow into the trachea 9 and finally be discharged through the air outlet 10. The air outlets 10 are respectively oriented towards the closed position of the window door 3 of the transfer window 1. After the airbag 12 is squeezed, the gas is discharged through the air outlet 10, and the air flow discharged from the air outlet 10 will flow towards the closed position of the window door 3, so as to blow the dust outside or near the window door 3 outward, and the external dust cannot enter the inside of the transfer window 1, thus realizing the dust prevention of the transfer window. By rotatably connecting the diagonal rod 6 to the window door 3, and the other end of the diagonal rod 6 is rotatably connected to the connecting seat 14. When the diagonal rod 6 is rotatably connected to the window door 3 and the connecting seat 14, it can prevent the diagonal rod 6 from being blocked. When the window door 3 opens, it will drive the diagonal rod 6 to move at the same time. The diagonal rod 6 is in an inclined state in the initial state. When the diagonal rod 6 is driven by the window door 3, the other end of the diagonal rod 6 will move forward.
