The cross arm of the connecting plate 250 is opposite to the top wall of the fixed block 210, the telescopic cylinder 240 is fixed in the fixed block 210, and the piston rod of the telescopic cylinder 240 penetrates through the top wall of the fixed block 210 and is fixedly connected with the bottom wall of the connecting plate 250 through the connecting plate. The second clamping bar 230 is fixed on the top wall of the connection plate 250, and the top wall of the second clamping bar 230 is located below the clamping portion 221. The top wall of the connecting plate 250 may further be provided with a corresponding pad 270 to adjust the height of the second clamping bar 230, and the size and shape of the particular pad 270 may be designed according to the actual installation space, which is not limited in this application. The top wall of the second clamping bar 230 corresponds to the bottom wall of the transverse plate of the 7-shaped clamping portion 221.

When the film is clamped, the telescopic cylinder 240 drives the connecting plate 250 to move, so that the second clamping rod 230 is separated from the clamping part 221, the film can enter between the second clamping rod 230 and the clamping part 221, and the telescopic cylinder 240 drives the connecting plate 250 to rise to push the second clamping rod 230 to be abutted against the clamping part 221, so that the film is fixed between the second clamping rod 230 and the clamping part 221, and the film is clamped.
