In actual operation, in order to analyze the impact resistance of paint layers of different materials or paint layers of different thicknesses, different areas on the paint board 5 can be coated in different areas. When the corresponding impact head module 6 impacts the paint board 5, a more obvious comparative analysis can be performed on a board. After the paint board 5 is placed on the adjustment mechanism 1, it can also be moved and the impact position can be adjusted. A longer paint board 5 can obtain more experimental results.

Pull rings are provided on the upper ends of the two plug-in blocks 105, and the dimensions of the paint board 5 are consistent with the internal dimensions of the movable frame 103. A movable space is provided inside the base 101 near the rear of the movable frame 103, and the movable frame 103 slides in the movable space. Sliding space is provided inside the base 101 near the rear of the two fixed blocks 102, and the two fixed blocks 102 can move with the movement of the movable frame 103;

[0030] Specifically, when the plug blocks 105 on both sides are pulled out, the entire movable frame 103 can move with the paint board 5. After moving to the appropriate position, it can be inserted back into the corresponding slot 104 to limit the movable frame 103. When the paint board 5 is long, the part that is not under the impact mechanism 4 can be moved below it.
