The buffer plate 404 is slidably arranged in the second card slot 403. A countersunk hole 406 is provided at the bottom of the second card slot 403. A connecting rod 405 accommodated in the countersunk hole 406 is fixedly arranged at the bottom of the buffer plate 404. The spring 407 is located in the countersunk hole 406 and is sleeved on the connecting rod 405. The two ends of the spring 407 are respectively connected and fixed to the storage plate 4 and the buffer plate 404;

[0028] When the mounting plate 6 moves downward, the top of the buffer plate 404 can abut against the bottom of the mounting plate 6 .

[0029] In at least one embodiment, both sides of the storage plate 4 are respectively provided with a group of slide grooves 1 connected to the through hole 1 402, and a group of supporting plates 8 are slidably arranged in each of the two groups of slide grooves 1, one end of the supporting plate 8 is fixedly connected to the adjusting rod 801, and the end of the adjusting rod 801 extends to the outside of the storage plate 4. By setting the supporting plate 8, when it is necessary to disassemble the impact block 601, the supporting plate 8 is slid along the slide groove 1, so that the two groups of supporting plates 8 close the through hole 1 402, and then the mounting plate 6 is lowered to place the impact block 601 on the supporting plate 8, and the impact block 601 can be disassembled, which is convenient to operate.

[0030] In at least one embodiment, a slide groove 2 connected to the through hole 1 402 is provided on one side of the base 1, and a storage box 9 is slidably provided in the slide groove 2. The storage box 9 is provided to facilitate storage and cleaning of fragments after impact.

[0031] In at least one embodiment, the countersunk holes 406 are arranged in multiple groups and are spaced apart at the bottom of the card slot 401. By arranging multiple groups of countersunk holes 406, multiple groups of springs 407 can jointly support the buffer plate 404, thereby improving safety.

During the lifting and lowering process of the mounting plate 6, the fixing rod 5 limits the mounting plate 6 to ensure the stability of the lifting and lowering of the mounting plate 6. After rising to a suitable height, the mounting plate 6 is released, and the mounting plate 6 and the impact block 601 fall under the action of gravity, so that the impact block 601 impacts the insulation board in the card slot 1 401. When the insulation board breaks under the impact, the mounting plate 6 and the impact block 601 continue to descend, so that the two sides of the mounting plate 6 are respectively in contact with a group of buffer plates 404. When the mounting plate 6 presses the buffer plate 404 and continues to descend, the mounting plate 6 is supported vertically upward under the action of the spring 407, and finally the mounting plate 6 stops descending, avoiding the impact block 601 from colliding with the base 1 and the storage plate 4, thereby greatly improving the safety.
