[0022] In the embodiments, the rubber sheet 9 is matched with the through hole 18, the end of the connecting pipe 8 away from the connecting cylinder 7 extends to the outside of the shell body 1 through the through hole 18, and the side surface of the connecting pipe 8 is provided with a plurality of convex strips.
[0023] In the embodiments, the two ends of the shell body 1 are respectively provided with the front end cover 2 and the rear end cover 3, the end of the shell body 1 close to the rear end cover 3 is provided with the wind cover 4, the wind cover 4 is located outside the rear end cover 3, and the side surface of the shell body 1 is fixedly connected with the support plate 12.
[0024] In the embodiment, the inner walls of the front end cover 2 and the rear end cover 3 are in close contact with the side surfaces of the shell body 1, and the inner walls of the wind cover 4 are in close contact with the side surfaces of the rear end cover 3 and the shell body 1 respectively.
[0025] In the embodiment, the side surfaces of the front end cover 2 and the rear end cover 3 are provided with the first connecting blocks 13, and the side surfaces of the wind cover 4 are provided with the second connecting blocks 14, and the side surfaces of the wind cover 4 are provided with the grooves 15 matched with the first connecting blocks 13.
