When the extrusion block 26 moves, it will squeeze or move away from the sealing cover, and the alcohol box 9 can be opened and closed through the cooperation of the first torsion spring. When the push plate 24 moves, it will drive the round rod 15 to move. When the round rod 15 moves, it will squeeze or move away from the second pull rope 1101. The second pull rope 1101 drives the reel 23 to rotate, and the reel 23 drives the baffle 22 to flip. Through the cooperation of the second torsion spring, the lens of the microscope 7 is blocked.

[0020] Further, such as Figure 4 As shown, a spring 20 is installed on the outer wall of the disk 4, a fixing plate 5 is installed on the side of the spring 20 away from the disk 4, and the lower end surface of the fixing plate 5 is installed on the support frame 1; When the round pin 13 does not squeeze the first pull rope 11, the spring 20 contracts, driving the disc 4 to return to its original position.

[0021] Further, such as Figure 4 As shown, the outer wall of the first pull rope 11 is abutted against the first pulley 2 and the second pulley 10, the first pulley 2 is fixedly mounted on the upper end surface of the support frame 1, and the second pulley 10 is rotatably mounted on the lower end surface of the support frame 1; The second pulley 10 can move and rotate following the first pull rope 11 to prevent the first pull rope 11 from derailing.

[0022] Further, such as Figure 5 As shown, an electric telescopic rod 29 is installed on the inner wall of the fixed frame 12, and the output shaft of the electric telescopic rod 29 is rotatably connected to a gear 28, the upper side of the gear 28 is meshed with the first rack 25, and the lower side of the gear 28 is meshed with a second rack 27, the second rack 27 is slidably connected to the fixed frame 12, and the lower end surface of the second rack 27 is fixedly connected to the round pin 13; When the electric telescopic rod 29 is working, it drives the gear 28 to move, and the gear 28 drives the first rack 25 and the second rack 27 to move on the fixed frame 12. When the first rack 25 does not move, the gear 28 drives the second rack 27 to move on the first rack 25. When the second rack 27 does not move, the gear 28 drives the first rack 25 to move on the second rack 27.

[0023] Further, such as Figure 3 As shown, a first support plate 14 is installed on the upper end surface of the support frame 1, a servo motor 17 is installed on the outer wall of the first support plate 14, a screw rod 16 is fixedly installed on the output shaft of the servo motor 17, and the screw rod 16 is threadedly connected to the microscope 7; The servo motor 17 works to drive the screw rod 16 to rotate, and the screw rod 16 drives the microscope 7 to move along the axial direction of the quartz tube 8 to detect different positions.

[0024] Further, such as Figure 4 As shown, a tension spring 601 is installed between the fixing frame 6, and the elastic coefficient of the tension spring 601 is greater than that of the spring 20; When the disk 4 moves the tension spring 20, since the elastic coefficient is smaller than the tension spring 601, the fixing frame 6 will not be driven to move.

[0025] Further, such as Figure 1 As shown, a plurality of supporting legs 3 are installed on the lower end surface of the supporting frame 1.

[0026] Working principle: Step 1: After connecting the external power supply and controller, push the fixing frame 6 to one side of the fixing plate 5. At this time, the fixing frame 6 stretches the tension spring 601, and the space between the fixing frames 6 becomes larger. Then, the two ends of the quartz tube 8 of a certain specification are sequentially placed inside the fixing frames 6 on both sides. Then, the electric telescopic rod 29 is controlled to extend. The electric telescopic rod 29 pushes the first rack 25 and the second rack 27 to move on the fixing frame 12 through the gear 28. At this time, the first rack 25 drives the extrusion block 26 and the push plate 24 to move; At this time, the extrusion block 26 no longer squeezes the sealing cover on the alcohol box 9. The sealing cover will flip over under the action of the first torsion spring. At this time, the alcohol box 9 is opened. At the same time, the push plate 24 drives the round rod 15 to squeeze the second pull rope 1101. The second pull rope 1101 begins to tighten and pulls the reel 23 to rotate. The reel 23 drives the baffle 22 to flip over and no longer blocks the microscope 7 until the push plate 24 moves to the specified position. At this time, the lens can be wiped with the alcohol in the alcohol box 9.

[0027] Step 2: When the first rack 25 does not move, the gear 28 moves on the first rack 25. At this time, the gear 28 continues to push the second rack 27 to move. The second rack 27 drives the round pin 13 to move. The round pin 13 squeezes the first pull rope 11. The first pull rope 11 drives the disc 4 to move away from the fixed plate 5. The disc 4 stretches the spring 20 and drives the connecting rod 18 to move. At this time, the connecting rod 18 squeezes the rotating rod 19. The rotating rod 19 rotates with the connection with the third support plate 32 as the rotating axis. The rotating rod 19 squeezes the sliding rod 33 away from the connecting rod 18. The sliding rod 33 drives the rubber wheel 31 to clamp the quartz tube 8 through the second support plate 30; At this time, if the diameters of the two sides of the quartz tube 8 are different, after the rubber wheel 31 on the side with a larger diameter completes clamping the quartz tube 8, as the second rack 27 continues to move, the round pin 13 will continue to squeeze the first pull rope 11, and the first pull rope 11 will move on the outer wall of the round pin 13 until the rubber wheel 31 on the side with a smaller diameter completes clamping the quartz tube 8, thereby achieving stable clamping even if the diameters of the two ends of the quartz tube 8 are inconsistent due to process limitations.

[0028] Step 3: After the clamping is completed, the electric telescopic rod 29 stops working, and the quartz tube 8 is observed and inspected through the microscope 7. At this time, the quartz tube 8 can be manually rotated so that different surfaces face the microscope 7 for inspection. Then, the servo motor 17 can be controlled to rotate, driving the screw rod 16 to rotate. The screw rod 16 drives the microscope 7 to move axially along the quartz tube 8, thereby realizing the full inspection of the outer wall of the quartz tube 8. In this process, there is no need to change the direction of the quartz tube 8 for multiple times, making it more convenient to inspect, thereby improving efficiency.

[0029] Step 4: After the detection is completed, the electric telescopic rod 29 contracts, driving the gear 28 to move, and the gear 28 drives the first rack 25 and the second rack 27 to return to the initial position. At this time, the spring 20 contracts, and the rubber wheel 31 no longer clamps the quartz tube 8. At the same time, the extrusion block 26 squeezes the sealing cover, and the alcohol box 9 is closed. The round rod 15 no longer squeezes the second pull rope 1101, and the second torsion spring drives the reel 23 to rotate, and the reel 23 drives the baffle 22 to flip, thereby completing the shielding of the microscope 7 lens.
