The left and right ends of the lead screw 3 have opposite thread directions, and sliders 4 are connected above the left and right ends of the lead screw 3. Moreover, moving blocks 5 are connected above the sliders 4. And the lead screw 3 is threadedly connected to the sliders 4. The sliders 4 are fixedly connected to the moving blocks 5 above. And the moving blocks 5 are threadedly connected to a first threaded rod 6. One end of the first threaded rod 6 is connected to a handle, and the surface of the handle is provided with anti-slip lines. And the handle is made of metal. And the front end of the first threaded rod 6 is rotatably connected to the interior of a moving plate 7. The moving plate 7 is slidably connected to a placement table 8. And the placement table 8 is slidably connected to a slide bar 9. And an infrared emitter 10 is fixedly connected to the surface of the slide bar 9;

[0024] During use, the first motor 2 inside the base 1 is started through the controller to drive the lead screw 3 to rotate, so that the sliders 4 above the two ends of the lead screw 3 move towards the middle at the same time, and at the same time drive the moving blocks 5 above to move. At this time, the acrylic plate is placed above the placement table 8 above the moving blocks 5 on both sides. At this time, the first threaded rods 6 on both sides of the moving blocks 5 can be rotated, so that the first threaded rods 6 drive the moving plate 7 to move, so that the moving plate 7 slides inside the placement table 8, so that the placement table 8 slides above the slide bar 9. At the same time, the distance between the infrared rays emitted by the infrared emitter 10 and the acrylic plate is adjusted, and the height of the placement table 8 is adjusted according to the angle at which the acrylic plate needs to be bent;

[0025] The upper part of the base 1 is fixedly connected to a fixed rod 11, and the front end of the fixed rod 11 is fixedly connected to a fixed block 12. And the fixed block 12 is connected to a rotating shaft 16 through a rotating mechanism. The rotating mechanism includes a fixed block 12, a second motor 13, a first gear 14, a second gear 15, and a rotating shaft 16. The second motor 13 is fixedly connected inside the fixed block 12, and the front end of the second motor 13 is fixedly connected to the first gear 14. And the first gear 14 meshes with the second gear 15. The second gear 15 is fixedly connected to the rotating shaft 16. The lower part of the rotating shaft 16 is fixedly connected to a rotating rod 17. The rotating rod 17 is a square rod. A controller is arranged above the fixed rod 11. And the rotating rod 17 is slidably connected to a second threaded rod 18. And the second threaded rod 18 is threadedly connected to the interior of the fixed block 12. The lower end of the second threaded rod 18 is rotatably connected to the upper end of a pressure sensor 19. And a pressing block 20 is fixedly connected below the pressure sensor 19. The lower part of the fixed block 12 is fixedly connected to a support rod 21. And the support rod 21 is rotatably connected to a rotating block 22. And a limiting rope 23 is arranged on the surface of the rotating block 22. The limiting rope 23 is connected to the pressure sensor 19 through a guide pulley 24. And the guide pulley 24 is fixedly connected to the fixed block 12;

[0026] At this time, the second motor 13 is started to drive the first gear 14 to rotate. Since the first gear 14 and the second gear 15 rotate, and the second gear 15 and the rotating shaft 16 rotate, the rotating shaft 16 drives the rotating rod 17 to rotate, causing the rotating rod 17 to drive the second threaded rod 18 to rotate. At the same time, the rotating rod 17 slides inside the second threaded rod 18. At this time, the second threaded rod 18 drives the pressure sensor 19 below to descend, so that the pressing block 20 below the pressure sensor 19 contacts the acrylic plate to press the acrylic plate. At the same time, when the pressure sensor 19 descends, the limiting rope 23 is pulled to move, so that the limiting rope 23 drives the rotating block 22 to rotate above the support rod 21 through the guide wheel 24 to limit the pressing block 20 and prevent the second threaded rod 18 from completely turning out. When the bending angle of the acrylic plate blocks the infrared rays emitted by the infrared emitter 10, the specific pressure borne by the acrylic plate can be understood through the pressure sensor 19 at this time.

[0027] Working principle: When using the compressive strength detection device for the light guide acrylic plate, during use, the first motor 2 inside the base 1 is started by the controller to drive the lead screw 3 to rotate, so that the sliders 4 above both ends of the lead screw 3 move towards the middle at the same time, and at the same time drive the moving block 5 above to move. At this time, the acrylic plate is placed on the placement table 8 above the moving blocks 5 on both sides. At this time, the first threaded rods 6 on both sides of the moving block 5 can be rotated, so that the first threaded rods 6 drive the moving plate 7 to move, so that the moving plate 7 slides inside the placement table 8, so that the placement table 8 slides above the sliding rod 9. At the same time, the distance between the infrared emitter 10 emitting infrared rays and the acrylic plate is adjusted, and the height of the placement table 8 is adjusted according to the angle at which the acrylic plate needs to be bent. At this time, the second motor 13 is started to drive the first gear 14 to rotate. Since the first gear 14 and the second gear 15 rotate, and the second gear 15 and the rotating shaft 16 rotate, the rotating shaft 16 drives the rotating rod 17 to rotate, causing the rotating rod 17 to drive the second threaded rod 18 to rotate. At the same time, the rotating rod 17 slides inside the second threaded rod 18. At this time, the second threaded rod 18 drives the pressure sensor 19 below to descend, so that the pressing block 20 below the pressure sensor 19 contacts the acrylic plate to press the acrylic plate. At the same time, when the pressure sensor 19 descends, the limiting rope 23 is pulled to move, so that the limiting rope 23 drives the rotating block 22 to rotate above the support rod 21 through the guide wheel 24 to limit the pressing block 20 and prevent the second threaded rod 18 from completely turning out. When the bending angle of the acrylic plate blocks the infrared rays emitted by the infrared emitter 10, the specific pressure borne by the acrylic plate can be understood through the pressure sensor 19 at this time.

[0028] Thus, a series of operations are completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
