[0033] When in use, first place the test material on the carrier plate 2 and clamp the test material with the fixing assembly. During testing, the motor 5 can drive the shift block 6 to shift the shift rod 14 so that it is above the shift block 6.

The top of the threaded rod 16 is fixedly connected to the bottom of the pressing plate 15, and the threaded rod 16 passes through the outer side of the middle part of the bearing plate 2. The bottom of the outer wall of the threaded rod 16 is threadedly connected with a knob 17. A sliding hole 18 is opened on the outer side of the middle part of the bearing plate 2, and the threaded rod 16 is located in the sliding hole 18.

[0035] After rotating the knob 17 to make it away from the bearing plate 2, the pressing plate 15 and the threaded rod 16 can be pulled to slide on the bearing plate 2, and the position of the pressing plate 15 on the bearing plate 2 can be adjusted. After reversing the knob 17, the pressing plate 15 can be pulled close to the bearing plate 2, and then the test material can be clamped between the pressing plate 15 and the bearing plate 2.

A pressure sensor 24 is arranged on the top surface of the partition plate 23, and the pressure sensor 24 is located below the bearing plate 2.

[0039] By driving the electric push rod 22, the partition plate 23 can be pushed out to make the pressure sensor 24 contact the bearing plate 2 and lift the bearing plate 2. At this time, the impact force generated during knocking can act on the pressure sensor 24 along the test material and the partition plate 23, and then the magnitude of the impact force applied to the test material can be detected.

[0040] Refer to Figure 1 , Figure 3 , Figure 4 and Figure 5A sliding column 25 is fixedly connected to the outer middle part of the bottom surface of the bearing plate 2, and a limit plate 26 is fixedly connected to the bottom of the sliding column 25.
