[0002] The guiding self-checking reticle photoelectric imaging detection microscope objective lens combines automated imaging and precision microscope design, and is widely used in fields such as biomedicine, materials science, and industrial inspection. This device integrates self-checking and reticle functions, and can automatically adjust the imaging system in real time to ensure high-precision image acquisition. Photoelectric imaging technology converts optical images into electronic signals, providing high-definition and high-resolution images.

[0019] 3. Through the setting of the fixing component, when the specimen slide is placed on the top of the stage, the clamping piece can clamp the specimen slide, preventing the specimen slide from shaking during the observation by the experimenter and improving the stability during detection. At the same time, the elastic piece applies pressure to the clamping piece to ensure that the clamping piece and the specimen slide are in non-rigid contact, preventing damage to the specimen slide due to excessive clamping force.

[0020] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. Description of the Drawings

The other end of the spiral spring 13 is fixedly connected with a support shell 14. The top of the support shell 14 is fixedly connected with the support ring 5. The surface of the rotating rod 6 is movably connected with the inner wall of the support ring 5 through a bearing. One side of the rotating rod 6 is fixedly connected with a limiting block 15. One side of the limiting block 15 is provided with a vertical rod 16. The bottom of the vertical rod 16 is fixedly connected with the support ring 5.

[0037] Specifically: The top of the protective pad 7 is in contact with the bottom of the observation objective lens 4, and the protective pad 7 can be used to shield and protect the bottom of the observation objective lens 4. One side of the baffle 9 is in contact with the adjusting piece 8. When the adjusting piece 8 follows the rotation of the rotating disk 3, the baffle 9 can be used to push the adjusting piece 8.

The spiral spring 13 has the function of winding and storing energy, and can reset the rotating rod 6.

[0038] Embodiment Three

[0039] Please refer to Figure 1-8 , on the basis of Embodiment One, a moving groove 21 is opened inside the clamping piece 11. A sliding rod 22 is fixedly connected inside the moving groove 21. A limiting rod 23 is slidably connected to the surface of the sliding rod 22. A return spring 24 is sleeved on the surface of the sliding rod 22. One end of the return spring 24 is fixedly connected with the limiting rod 23. A fixing block 25 is fixedly connected to the top of the stage 1. A fixing groove 26 is opened on one side of the fixing block 25. A vertical frame 27 is fixedly connected between the stage 1 and the lens barrel 2. An eyepiece 28 is installed on the top of the lens barrel 2. A base 29 is fixedly connected to the bottom of the stage 1. A supplementary light mirror 30 is fixedly connected to one side of the base 29.

[0040] Specifically: one side of the limit block 15 is in contact with the vertical rod 16, and the reset angle of the rotating rod 6 can be limited when the clockwork spring 13 resets the rotating rod 6. The surface of the rotating disk 3 is movably connected to the inner wall of the supporting disk 17 through the bearing, which can facilitate the experimenter to manually rotate the rotating disk 3. The elastic sheet 20 has an elastic effect and can play a buffering role between the pressure rod 19 and the clamping sheet 11. The reset spring 24 has the function of compressing energy storage and can reset the sliding rod 22. A fixing groove 26 is provided on one side of the fixed block 25. When the sliding rod 22 rotates with the clamping sheet 11, it can be inserted into the fixing groove 26 to fix the position of the clamping sheet 11.

[0041] The working principle of the present invention is: when the experimenter needs to adjust the position of the observation lens 4, he can manually rotate the rotating disk 3, and the rotating disk 3 drives the observation lens 4 to rotate with the supporting disk 17 as the axis. When the observation lens 4 rotates, it will drive the rotating rod 6 and the adjusting plate 8 to rotate. When the adjusting plate 8 contacts the baffle 9, the baffle 9 will push the adjusting plate 8 to rotate. The adjusting plate 8 drives the rotating rod 6 and the protective pad 7 to rotate and twist the clockwork spring 13. When the observation lens 4 is aligned with the lens barrel 2, the protective pad 7 can be completely detached from the bottom of the observation lens 4, which is convenient for the experimenter to perform microscopic observation of the slide 12.

[0042] After the microscopic observation is completed, the user can rotate the rotating disk 3 and the observation lens 4 clockwise again. When the observation lens 4 rotates, the adjusting plate 8 is driven to rotate. When the adjusting plate 8 rotates, it disengages from the baffle 9. At this time, the clockwork spring 13 will reset the rotating rod 6. The rotating rod 6 drives the protective pad 7 to rotate to the bottom of the observation lens 4 again. The protective pad 7 is used to block the observation lens 4 that deviates from the lens barrel 2. By blocking the bottom of the observation lens 4, impurities such as dust are prevented from entering the observation lens 4, thereby playing an automatic protection role.
