One end of the fixing spring 107 is fixedly connected with a clamping plate 102 extending to the outside of the fixing groove 106. One end of the clamping plate 102 is fixedly connected with a shifting frame 101 penetrating the reserved groove 108. The elastic force of the fixing spring 107 is utilized to make one end of the clamping plate 102 close to the inner wall of the air inlet, thereby improving the clamping firmness between the screen frame 2 and the inner wall of the air inlet, and avoiding the gap between the two due to production errors, which affects the firmness and stability of the installation of the screen frame 2.

[0029] In this embodiment, the shape of the shifting frame 101 in the top view is U-shaped, and one end of the shifting frame 101 and the front side of the clamping plate 102 are welded into an integrated structure. The U-shaped shifting frame 101 makes it easy for the user to use the shifting frame 101 to slide the clamping plate 102.

[0030] In this embodiment, anti-skid patterns 103 are evenly spaced at one end of the clamping plate 102. The cross-section of the anti-skid patterns 103 is an isosceles trapezoid.
