[0031] In this embodiment 1: the crushing bearing mechanism includes a first lower pressing block 501, a spherical pressure head 502, a first pressure platform 503 and a spherical pressure groove 504. The first lower pressing block 501 is threadedly connected to the inside of the second threaded mounting port 202. The spherical pressure head 502 is integrally arranged at the bottom of the first lower pressing block 501. The first pressure platform 503 is threadedly connected to the inside of the first threaded mounting port 104. The spherical pressure groove 504 is opened on the upper surface of the first pressure platform 503 to ensure that sample debris can be easier to clean.

[0032] In this embodiment 2: the crushing bearing mechanism includes a second lower pressing block 505, a cylindrical pressure head 506, a second pressure platform 507 and a cylindrical pressure groove 508. The second lower pressing block 505 is threadedly connected to the inside of the second threaded mounting port 202, the cylindrical pressure head 506 is integrally arranged at the bottom of the first lower pressing block 501, the second pressure platform 507 is threadedly connected to the inside of the first threaded mounting port 104, and the cylindrical pressure groove 508 is opened on the upper surface of the first pressure platform 503 to ensure that the pressure on the sample is more uniform.

[0033] Working principle: Since the force is mutual, the pressure applied by the connecting guide column 301 to the pressure measuring spring 312 is equal to the reverse elastic force of the pressure measuring spring 312 on the connecting guide column 301. This pressure is transmitted through the pressure measuring spring 312, the threaded push cylinder 307, the lifting push cylinder 310, the floating connecting seat 201, and the first pressing block 501 or the second pressing block 505, so that this pressure becomes the pressure applied to the sample. When the pressure measuring spring 312 undergoes elastic deformation, the elastic force of the pressure measuring spring 312 is proportional to the elongation of the pressure measuring spring 312. Therefore, by controlling the compression length of the extruded pressure measuring spring 312, the pressure on the pressure measuring spring 312, that is, the pressure applied to the sample, can be controlled. Since the elastic force of the pressure measuring spring 312 contracted from the lower surface of the extrusion block 401 to the upper surface of the stop block 406 and the elastic force of the fitting spring 405 contracted from the lower surface of the extrusion block 401 to the upper surface of the stop block 406 are both fixed values, and since the rotation angle of the adjusting wheel 308 is proportional to the lifting length of the lifting push cylinder 310, this fixed value is directly used as the initial scale of the scale ring 306, and the subsequent elongation of the pressure measuring spring 312 is directly represented by the increase in the angle between the scale reference line 309 and the initial scale. Therefore, when the adjusting wheel 308 is turned, the scale reference line 309 can be compared with the scale on the scale ring 306 to ensure that the set pressure value can be directly read on the surface of the adjusting wheel 308; Therefore, when in use, first turn the adjustment wheel 308 to adjust the spring strength. When turning the adjustment wheel 308, the adjustment wheel 308 pushes the lifting push cylinder 310 to extend or retract inside the guide cylinder 303 through the thread, thereby squeezing the pressure measuring spring 312 to contract or extend, thereby adjusting the extension length of the pressure measuring spring 312. When turning the adjustment wheel 308, the pressure value is set by comparing the scale reference line 309 with the scale on the scale ring 306, that is, the pressure that the sample is subsequently subjected to. When setting, this pressure value is set to be slightly larger than the qualified pressure of this sample; Then, the floating connection seat 201 is lifted upwards, and the sample is placed inside the spherical pressure groove 504 or the cylindrical pressure groove 508, and then the floating connection seat 201 is lowered, so that the spherical pressure head 502 or the cylindrical pressure head 506 is in contact with the surface of the sample. Since the weight of the balancing weight block 110 is balanced with the floating pressing mechanism, the pressure regulating mechanism, the pressing limit mechanism and the first pressing block 501 or the second pressing block 505 of the crushing bearing mechanism, the weight of the floating pressing mechanism, the pressure regulating mechanism, the pressing limit mechanism and the first pressing block 501 or the second pressing block 505 of the crushing bearing mechanism will not cause a significant interference to the pressure on the sample. Then, the locking motor 413 is started, and the locking motor 413 drives the bidirectional threaded rod 411 to rotate through the worm gear reducer 412. When the bidirectional threaded rod 411 rotates, it pushes the locking slider 409 to move toward the first guide support column 102, so that the anti-skid pad 410 presses the first guide support column 102 tightly to ensure that the stop block 406 is locked; Then, the pressure motor 106 is started, and the pressure motor 106 drives the active synchronous wheel 107 to rotate. When the active synchronous wheel 107 rotates, it drives the synchronous belt 109 to move. When the synchronous belt 109 moves, it pulls the extrusion block 401 down. The extrusion block 401 drops down and squeezes the pressure measuring spring 312 to contract until the extrusion block 401 drops to fit the stop block 406. At the same time, the pressure measuring spring 312 transfers the pressure to the sample, so that the pressure measuring spring 312 is subjected to the same pressure. Then, the pressure motor 106 is turned off, and the pressure measuring spring 312 pushes the extrusion block 401 to rise and reset, and then the locking motor 4 is started. 13 is reversed and closed. During the reverse rotation, the locking motor 413 drives the bidirectional threaded rod 411 to rotate in the opposite direction through the worm gear reducer 412. When the bidirectional threaded rod 411 rotates, it pushes the locking slider 409 to move away from the first guide support column 102, so that the anti-slip pad 410 is separated from the first guide support column 102, and the locking is released. Then, the floating connecting seat 201 is lifted upward to take out the sample, and observe whether the sample is cracked or broken. If it is cracked or broken, the sample is unqualified. If it is not cracked or broken, the sample is qualified. Then, the floating connecting seat 201 is lifted upward again, and a new sample from the same batch is used for re-testing.
