Fixed connections are provided on the left and right sides of the bottom of the test bench 4. The fixed ring 12 is provided with a spring pressure gauge 11 at the bottom of the fixed ring 12. When the test bench 4 moves upward, the test object 15 contacts the impact plate 13 and performs extrusion. At this time, the pressure will be transmitted to the spring pressure gauge 11. The scale line 19 of the spring pressure gauge 11 will show the force condition. Once the test object 15 is broken, the maximum pressure value that the test object 15 can withstand can be measured. When the telescopic rod 1401 contracts or extends, the moving plate 1402 will move up and down on the impact plate 13.

When the test object 15 is broken, the push plate 1407 moves forward to push the broken test object 15 into the collection box 1408 on the front side of the push plate 1407. When the collection box 1408 is filled with broken materials to a certain extent, the handle 20 is pulled to move it out and dump it.
