[0027] When the impact test of the extruded plate 4 is required, the second impact column 1e is moved upward. The second impact column 1e and the first impact column 1d are both made of metal. After the second impact column 1e moves to the top, it is released. When it falls to the bottom, it will hit the first impact column 1d. The bottom of the first impact column 1d will hit the top of the extruded plate 4, thereby completing the impact test. When the extruded plate 4 needs to be replaced, the two telescopic columns 804 are operated so that the output ends of the two telescopic columns 804 drive the two connecting blocks 803 and the two U-shaped blocks 801 to move in opposite directions. The movement of the two U-shaped blocks 801 will drive the two cover plates 6 to move in opposite directions. By screwing the two screws 2e to move upward and drive the two extrusion blocks 2d to move upward, the first The impact column 1d moves upward. At this time, the extruded plate 4 to be tested can be placed on the top of the support table 3 and the two support blocks 2b, and the two screws 2e are turned to drive the two extrusion blocks 2d to move downward, so that the two extrusion blocks 2d clamp the extruded plate 4, and then the two telescopic columns 804 are operated so that the output ends of the two telescopic columns 804 drive the two connecting blocks 803, the two U-shaped blocks 801 and the two cover plates 6 to move toward the opposite ends, and the second impact column 1e is moved upward to the top and rotated to the left. At this time, the bolts fixing the four mounting blocks 11 are removed, so that the four mounting blocks 11 can drive the limit ring 10 and the first impact column 1d to move upward and disengage from the fixed block 1c, thereby realizing the replacement of the first impact column 1d of different sizes.
