The side surfaces of the two support plates 1 that are away from each other are provided with strip holes 8, and the side surfaces of the two vertical plates 11 that are away from each other are fixedly connected with fixing screws 9. The ends of the two fixing screws 9 that are away from each other pass through the strip holes 8 and extend to the outside of the strip holes 8, and the outer surfaces of the two fixing screws 9 are threadedly connected with locking nuts 10; specifically, the second bearings 12 provided on the vertical plates 11 can support the rollers 13, and the setting of the rollers 13 can be used to limit and guide the film, and the cooperation of the strip holes 8, the fixing screws 9 and the locking nuts 10 can lock and fix the vertical plates 11 and the rollers 13 after height adjustment.

[0025] In this embodiment, the upper surfaces of the two vertical plates 11 are fixedly connected with a top plate 14, and the upper surface of the top plate 14 is provided with two grooves 15.
