The pressure plate moves upward along the first inclined groove through the inclined slider and moves outward to clamp and pull the two sides of the sample paper outward, so that the sample paper is in a taut state and becomes flat, which is convenient for subsequent testing. The pressure plate moves up to contact the ball, which drives the slide rod to move up and compress the spring. The elastic force of the spring squeezes the ball, so that the pressure plate has a downward squeezing force on the sample paper, which further enhances the clamping effect on the sample paper.

[0018] 2. When using this utility model, simply align the L-shaped plate with the plug rod and insert it to install the sandpaper mounting base on the L-shaped plate. Then, start the drive motor. The output end of the drive motor drives the rotating plate to move up and down in the straight slide groove, while simultaneously driving the L-shaped plate to move back and forth along the second guide rail assembly. The L-shaped plate drives the sandpaper mounting base and sandpaper to rub the sample paper, which is clamped and tightened by the pressing assembly, back and forth to perform an anti-fading test.
