The front surface of the focusing adjustment moving base 5 is fixedly connected to the focusing lens barrel 6. The movement of the focusing adjustment moving base 5 can synchronously drive the focusing lens barrel 6 to move, thereby achieving accurate position adjustment of the focusing lens barrel 6 to meet different measurement needs. A converter 7 is provided on the lower surface of the focusing lens barrel 6. The converter 7 can switch different optical components according to measurement needs, and cooperate with the focusing lens barrel 6 to achieve different optical functions, ensuring the diversity of the measurement process. A data connection line 8 is fixedly connected to the outer surface of the focusing lens barrel 6. The optical components inside the focusing lens barrel 6... The photosensitive component is connected to an external control host via data connection cable 8 to transmit optical signal data. A focusing adjustment linear motor 12 is fixedly connected to the front surface of the connecting arm 3, providing stable mounting support for the focusing adjustment linear motor 12 and ensuring its normal operation for focusing adjustment. A connecting plate 13 is fixedly connected to the output end of the focusing adjustment linear motor 12. When the focusing adjustment linear motor 12 is working, its output end can drive the connecting plate 13 to move linearly, thereby driving the components mounted on the connecting plate 13 to move synchronously. A first angle adjustment motor 14 is fixedly connected to the front surface of the connecting plate 13, providing a mounting platform for the first angle adjustment motor 14. The first angle adjustment motor 14 can be stably installed and operate normally to achieve angle adjustment. The output end of the first angle adjustment motor 14 is fixedly connected to the mounting bracket 15. When the first angle adjustment motor 14 is working, its output end can drive the mounting bracket 15 to rotate, providing power for the angle adjustment of the components on the mounting bracket 15. A limit block 16 is fixedly connected to the upper surface of the mounting bracket 15. The limit block 16 can limit the position of the condenser lens 17 mounted on the mounting bracket 15, preventing the condenser lens 17 from shifting during use. A second angle adjustment motor 18 is fixedly connected to the side wall of the mounting bracket 15. The mounting bracket 15 provides a stable installation position for the second angle adjustment motor 18, ensuring that the second angle adjustment motor 18 can operate normally to adjust the angle of the condenser lens 17.The output end of the second angle adjusting motor 18 is fixedly connected to the second angle adjusting rotating column 19. When the second angle adjusting motor 18 is working, its output end can drive the second angle adjusting rotating column 19 to rotate, thereby transmitting power for the angle adjustment of the condenser lens 17. One end of the second angle adjusting rotating column 19 is fixedly connected to the condenser lens 17. The rotation of the second angle adjusting rotating column 19 can drive the condenser lens 17 to rotate synchronously, thereby adjusting the angle of the condenser lens 17 to optimize the focusing effect. The left and right sides of the outer surface of the focusing adjustment linear motor 12 are fixedly connected to the lifting electric telescopic pump 20. The focusing adjustment linear motor 12 provides symmetrical installation positions for the lifting electric telescopic pump 20 to ensure that the lifting electric telescopic pump 20 can work stably. The output end of the lifting electric telescopic pump 20 is fixed. A lifting electric telescopic rod 21 is connected to the stage 9. When the lifting electric telescopic pump 20 is working, it drives the lifting electric telescopic rod 21 to extend and retract, providing power for the lifting and lowering of the stage 9. The stage 9 is fixedly connected to the upper surface of the lifting electric telescopic rod 21. The extension and retraction of the lifting electric telescopic rod 21 drives the stage 9 to rise and fall, realizing the height adjustment of the stage 9 to adapt to different measurement scenarios. A light-transmitting groove 23 is provided on the upper surface of the stage 9, allowing light to pass smoothly through the stage 9 and providing a light path for subsequent optical measurements. The stage 9 is detachably connected to a limiting clamp 11 via positioning bolts 10. The limiting clamp 11 can be fixed to the stage 9 via the positioning bolts 10, limiting and fixing the measurement sample on the stage 9 to prevent sample movement.

[0024] The stage 9 is located between the converter 7 and the condenser lens 17. This positional relationship allows the light emitted from the condenser lens 17 to be transmitted through the light-transmitting groove 23 on the stage 9 to the converter 7, and then into the focusing lens tube 6, forming a complete optical measurement path. The interior of the light-transmitting groove 23 is connected to the lower surface of the stage 9. This connection structure ensures that the light can smoothly enter the light-transmitting groove 23 from the lower surface of the stage 9 and then be transmitted upwards, ensuring smooth light transmission. The positioning bolts 10 are symmetrically arranged on the left and right sides of the upper surface of the stage 9. The symmetrical arrangement of the positioning bolts 10 makes the fixing of the limiting clamp 11 on the stage 9 more stable, the force more even, and the measurement better. The sample is positioned with the light-transmitting groove 23 located between two positioning bolts 10. This positioning allows the light-transmitting groove 23 to avoid obstructing the light transmission, ensuring the accuracy of optical measurements. The size of the condenser lens 17 matches the size of the mounting bracket 15, ensuring that the condenser lens 17 can be stably mounted on the mounting bracket 15 without loosening or shifting during use. The outer surfaces of the condenser lens 17 and the limiting block 16 abut against each other. The limiting block 16 further limits and fixes the condenser lens 17 by abutting against its outer surface, ensuring the accuracy of optical measurements. The optical mirror 17 is positioned stably, and the stage 9 is located above the condenser adjustment linear motor 12. This positional relationship allows the condenser adjustment linear motor 12 to more easily influence the position or focusing effect of the stage 9 by driving the movement of related components, thus optimizing the measurement process. The focusing adjustment linear motor 4 is located at the top of the front surface of the connecting arm 3. This top position allows the focusing adjustment linear motor 4 to better drive the focusing lens barrel 6 for position adjustment, avoiding positional interference with other components on the connecting arm 3. The connecting plate 13 is positioned parallel to the stage 9. This parallel positional relationship allows the focusing-related components mounted on the connecting plate 13 to... Maintaining a suitable relative position with the stage 9 ensures that the focusing effect can accurately act on the sample on the stage 9. The outer surface of the adjusting bolt 22 is threadedly connected to the connecting seat 2. The threaded connection allows the adjusting bolt 22 to tightly connect the connecting seat 2 and the connecting arm 3. The tightness of the connection can be easily adjusted by rotating the adjusting bolt 22. The outer surface of the connecting arm 3 is rotatably connected to the connecting seat 2. This rotatable connection allows the connecting arm 3 to rotate around the connecting seat 2, which facilitates the adjustment of the overall angle of the connecting arm 3 and subsequent assembled components to adapt to different measurement needs. At the same time, the adjusting bolt 22 can be used to fix the connecting arm 3 after rotation.

[0025] Working principle: First, place the wood fiber sample to be measured on the stage 9. Rotate the positioning bolt 10 to fix the limiting clamp 11 on the stage 9 and clamp the sample, ensuring a stable sample position. The sample must cover the light-transmitting groove 23 area. Rotate the adjusting bolt 22 to adjust the relative angle between the connecting arm 3 and the connecting seat 2, so that the connecting arm 3 drives the focusing adjustment linear motor 4, the focusing adjustment linear motor 12, and other components mounted on it to a suitable initial position. After adjustment, tighten the adjusting bolt 22 to fix the connecting arm 3, and start the lifting electric telescopic pump 2. 0. The lifting electric telescopic pump 20 drives the lifting electric telescopic rod 21 to extend and retract, thereby raising and lowering the platform 9. The platform 9 is adjusted to a suitable height between the converter 7 and the condenser lens 17. Then, the lifting electric telescopic pump 20 is turned off, and the first angle adjustment motor 14 is started. Its output end drives the mounting bracket 15 to rotate, adjusting the angle of the mounting bracket 15 to meet the focusing requirements. At the same time, the second angle adjustment motor 18 is started, and its output end drives the second angle adjustment rotating column 19 to rotate, thereby driving the condenser lens 17 to rotate, so that the angle of the condenser lens 17 meets the measurement requirements, and the focusing... The outer surface of the optical lens 17 abuts against the limiting block 16 to maintain stability. Then, the condenser adjustment linear motor 12 is activated, its output driving the connecting plate 13 to move, synchronously adjusting the linear position of the condenser lens 17 to ensure that the light emitted by the condenser lens 17 is accurately aligned with the light-transmitting groove 23 on the stage 9. After adjustment, the relevant motors are turned off, and the focus adjustment linear motor 4 is activated, its output driving the focus adjustment moving seat 5 to move, which in turn moves the focusing lens barrel 6, adjusting its position so that the focusing lens barrel 6 can clearly receive the light transmitted through the light-transmitting groove 23 and the converter 7. After the light is focused, the focusing adjustment linear motor 4 is turned off. The optical photosensitive component inside the focusing lens tube 6 senses the optical signal and transmits the sensed signal data to the external control host through the data connection line 8 fixed on the outer surface of the focusing lens tube 6. The host receives and processes the data to complete the measurement of the wood fiber length. After the measurement is completed, the positioning bolt 10 is loosened first, the sample on the stage 9 is removed, and then the components are restored to their initial positions through the adjusting bolt 22, the lifting electric telescopic pump 20, and other components. The power supply to the external control host and all motors and pumps is turned off.
