The second ratchet 19 is fixedly sleeved on the moving shaft 21, and the spring 22 is sleeved on the elastic telescopic shaft. When the spring 22 is in a normal state, the second A ratchet 17 engages with the second ratchet 19, the top of the left horizontal plate 23 near the right horizontal plate 24 is provided with a wedge-shaped surface, the left drain plate 4 is provided with a chute 26 near the end of the right drain plate 5, and one end of the left horizontal plate 23 Slidingly arranged in the chute 26, the chute 26 is provided with a spring one 27, and the two ends of the spring one 27 are respectively connected with the left drainage plate 4 and the left horizontal plate 23, when the wedge-shaped surface of the left horizontal plate 23 is connected with the right horizontal plate 24 When one end of the spring is in a compressed state, the dust-proof frame 1 is provided with a left limiting plate 28 and a right limiting plate 29 at intervals along the width direction, and the left limiting plate 28 and the right limiting plate 29 are respectively arranged on the ring double At both ends of the spur gear 8, when the annular double straight gear 8 is in contact with the left limit plate 28, the left horizontal plate 23 is in contact with the right horizontal plate 24, and when the annular double spur gear 8 is in contact with the right limit plate 29 , The left horizontal plate 23 is spaced from the right horizontal plate 24 to form a drain.
