The limit seat 21 is provided with a torsion spring rod 24 and an airbag 25, the airbag 25 is fixedly connected to the lower end of the limit seat 21, and a connection groove is provided on the side of the limit seat 21, so that the inside of the limit seat 21 can limit the winding roller 22. The size of the sealing fixing plate 210 is adapted to the size of the top of the limit seat 21, and the lower end of the support rod 212 is fixedly connected to the outside of the limit seat 21, and the sealing fixing plate 210 can effectively seal the top of the limit seat 21 to prevent dust from entering the inside of the limit seat 21. The present application uses a fixing device 2 to effectively place the winding roller 22 into the interior of the limiting seat 21, squeeze the airbag 25, and the airbag 25 will transport the internal gas to the interior of the air pressure chamber 28 through an air pipe 27. The air pressure chamber 28 will drive the air pressure rod 29 and the sealing fixing plate 210 to move, thereby sealing and protecting the top of the limiting seat 21 to prevent dust from falling into the interior of the limiting seat 21. At the same time, it can effectively prevent the advertising banner body 23 from being dislocated when stretched, and is highly practical.

[0023] When this embodiment is used, the winding roller 22 is first placed into the interior of the limiting seat 21, and the winding roller 22 will squeeze the airbag 25.
