A top bar 202 is movably attached to the left side of the ventilation grille 201, and the top bar 202 is fixedly connected to the top of the inner surface of the air inlet box 1. A fixed frame 203 is movably attached to the right side of the ventilation grille 201, and the fixed frame 203 is fixedly connected to the inner surface of the air inlet box 1. A fixing mechanism 3 is arranged below the air inlet box 1. The fixing mechanism 3 includes a sandwich box 301, and the sandwich box 301 is fixedly connected to the lower part of the air inlet box 1. A pulling bar 302 is slidably connected to the bottom of the inner surface of the sandwich box 301. There are two openings above the pulling bar 302, and the left side of the inner surface of the two openings is provided with an inclined surface. The two openings are adapted to a bearing seat 501. The pulling bar 302 movably penetrates through the left and right sides of the sandwich box 301. Pulling plates 303 are fixedly connected to the left and right sides of the pulling bar 302. A pull handle 304 is fixedly connected to the left side of the pulling plate 303. The number of the pulling plates 303 and the pull handle 304 is two, which are respectively arranged on the left and right sides of the pulling bar 302. An elastic component 4 is arranged above the pulling bar 302. The elastic component 4 includes a connecting piece 401, and the connecting piece 401 is fixedly connected to the upper part of the pulling bar 302. The right side of the connecting piece 401 is elastically connected to a support piece 403 through a spring 402. The spring 402 will apply a pulling force in the normal state to pull the connecting piece 401 to the right. The support piece 403 is fixedly connected to the bottom of the air inlet box 1. A clamping block component 5 is arranged above the pulling bar 302. The clamping block component 5 includes a bearing seat 501. A sliding rod 502 movably penetrates through the lower part of the bearing seat 501. The upper end of the sliding rod 502 is fixedly connected to the bottom of the air inlet box 1, and the lower end of the sliding rod 502 is fixedly connected to the bottom of the inner surface of the sandwich box 301.
