[0028] A limiting guide rod 12 is fixedly installed inside the outer fender 1 , and a surface of the limiting guide rod 12 is slidably connected to the inside of the sealing plate 13 .

[0029] By limiting the setting of the guide rod 12, it is convenient to limit the sealing plate 13, thereby preventing the sealing plate 13 from swinging, and reducing the problem of the sealing plate 13 swinging to the greatest extent.

[0030] A slideway 3 is provided on one side of the outer fender 1 , a connecting rod 4 is slidably connected inside the slideway 3 , a scraper 5 is fixedly installed on one side of the connecting rod 4 , and the connecting rod 4 is fixedly connected to the sealing plate 13 .

When the drive motor 2 rotates in the opposite direction, the sealing plate 13 is reset, and then the first air guide hole 6 is opened, which is convenient for exhaust. When the large gear 19 rotates, the large gear 19 drives the small gear 20 and the second rotating shaft 17 to rotate, and then the winding wheel 16 is rotated, and then the pull rope 18 on the winding wheel 16 is gradually unwound, so that the inner fender 7 is reset by the tension of the tension spring 10, so that the fixing rod 11 slides inside the through groove 9, and at the same time, the inner fender 7 slides out from the inside of the opening 8. When the large gear 19 rotates in the opposite direction, the inner fender 7 is retracted into the inside of the outer fender 1, which is convenient for the folding of the outer fender 1, thereby minimizing the wind resistance of the outer fender 1.
