[0023] In this embodiment, the base 1 serves as the foundation of the entire testing device, providing stable support for other components. The electric guide rails 3 achieve precise position adjustment through their respective moving members. The mounting ring 4 is used to mount the cylinders 5 and the test pressing block 6, and the slider 7 is used to mount the infrared rangefinder 8. By controlling the expansion and contraction of the cylinders 5, different pressures can be simulated on the wood to test the strength of the wood. The test pressing block 6 is used to directly act on the surface of the wood to detect the performance of the wood under the action of pressure. The infrared rangefinder 8 is used to monitor the bending degree of the wood under the action of pressure. The infrared rangefinder 8 can accurately measure the deformation degree of the wood, thereby evaluating its support performance.
[0024] In a further preferred embodiment of the present utility model, a mounting seat 13 is fixed to the bottom of the base 1, a blower 12 and a dust collection box 11 are mounted on the top of the mounting seat 13, the dust collection box 11 is fixed at the air inlet end of the blower 12, a connecting pipe 10 is fixed to the dust collection box 11, the connecting pipe 10 extends above the base 1, a dust suction pipe 9 is fixed to the air inlet end of the connecting pipe 10, and the dust suction pipe 9 is fixed to the slider 7.
[0025] In this embodiment, the mounting base 13 is used to mount the fan 12 and the dust collection box 11 to ensure the stability of the entire dust removal system. When the fan 12 operates, a negative pressure is generated to suck the dust in the environment into the dust collection box 11. The dust collection box 11 can be cleaned regularly to maintain its dust removal effect. It moves along with the movement of the slider 7 to ensure that the dust suction port is always close to the test wood area, effectively collecting the dust generated during the test.
[0026] In a further preferred embodiment of the present utility model, electric telescopic rods 14 are fixedly installed on both sides of the support frame 2. U-shaped plates 15 are hinged on the output rods of the two electric telescopic rods 14. Threaded rods 17 are installed on the two U-shaped plates 15 in a threaded manner. Clamping plates 16 are rotatably installed at the bottoms of the two threaded rods 17. The two clamping plates 16 are respectively in contact with the inner walls of the two U-shaped plates 15.
[0027] In this embodiment, the electric telescopic rod 14 can achieve telescopic movement through control, thereby adjusting the position of its output rod. The design of the U-shaped plate 15 enables it to conveniently clamp both sides of the wood.

The anti-slip pads can increase the friction between the clamping plate 16 and the wood, preventing the wood from sliding or shifting during the test, and ensuring the accuracy and stability of the test.
[0030] In a further preferred embodiment of the present utility model, a protective frame 19 sleeved outside the support frame 2 is slidably installed on the base 1. Observation windows 20 are provided on both sides of the protective frame 19. The protective frame 19 is used to isolate flying wood chips.
[0031] In this embodiment, the protective frame 19 is designed to completely or partially cover the support frame 2, thereby isolating the possible flying of wood chips during the test.

The user can easily adjust the position of the clamping plate 16 by rotating the adjustment block to adapt to different sizes of wood, improving the adaptability and operation convenience of the testing device. The design of the flexible hose section increases the flexibility of the connecting pipe 10. The use of the dust collection bag further improves the dust removal efficiency. It can effectively collect dust, prevent dust from accumulating and flying in the dust collection cylinder, and the replacement of the dust collection bag is also very convenient. The user only needs to take out the old dust collection bag and replace it with a new one, greatly simplifying the cleaning and maintenance process.
[0034] In a further preferred embodiment of the present utility model, two sliding grooves are provided on the base 1. Two limit blocks 21 are respectively slidably installed in the two sliding grooves. A plurality of the limit blocks 21 are all fixed to the bottom of the protective frame 19.
[0035] In this embodiment, the design of the sliding groove is used to ensure the stable sliding of the protective frame 19 on the base 1. Through the sliding of the limit blocks 21 in the sliding grooves, the protective frame 19 can perform opening, closing and locking operations.
[0036] In summary, compared with the related technologies, by setting two electric guide rails 3 to respectively adjust the positions of the test pressure block 6 and the infrared rangefinder 8, the deformation degree of the wood can be monitored during the pressure detection of the wood, so as to understand the supporting force of the wood. By setting the fan 12 in cooperation with the dust suction pipe 9, the wood dust can be extracted to prevent the sawdust from flying and polluting the environment. By setting the electric telescopic rod 14, woods of different sizes can be stabilized. By setting the protective frame 19, the sawdust generated by the fracture of the wood can be prevented from flying and shooting, thereby triggering dangerous accidents.
