The magnetism of one No. 1 magnet 14 is attracted to the magnetism of No. 2 magnet 31, and the magnetism of the other No. 1 magnet 14 is repelled by the magnetism of No. 2 magnet 31. Under the attraction and repulsion of the magnetism of the two No. 1 magnets 14 and No. 2 magnet 31 respectively, the magnetism of the two No. 1 magnets 14 can continuously attract and repel the magnetism of No. 2 magnet 31, so that the test tube 26 in the limiting sleeve 36 can continuously swing left and right under the magnetic force, so as to shake and mix the blood sample and saline in the test tube 26.
[0018] The positioning component includes a bearing shell 3 fixedly installed at the front end of the limiting frame 2. The bearing shell 3 supports the limiting post 16. The front and rear ends of the tube seat 25 are both extended with guide ridges 4. The guide ridges 4 penetrate the front and rear ends of the limiting frame 2 and serve as guides.

The two ends of the limiting post 16 penetrate from the two ends of the bearing shell 3 respectively, and the limiting post 16 and the bearing shell 3 are slidably engaged. The rear end of the limiting post 16 passes through the front end of the limiting frame 2 and the front end of the guide ridge 4 in sequence.

[0022] The outer surface of the limiting magnet 29 is inlaid with a first fixing shell 28. The lower end of the first fixing shell 28 is fixed to the inner bottom surface of the limiting frame 2. The first fixing shell 28 serves to fix the limiting magnet 29. The outer surface of the positioning magnet 30 is inlaid with a second fixing shell 33. The second fixing shell 33 serves to fix the positioning magnet 30. The upper end of the second fixing shell 33 is fixed to the cap 34. The upper end of the cap 34 is fixedly installed with multiple connecting frames 35 in a circular array. The upper end of the connecting frames 35 is fixed to the limiting sleeve 36. The connecting frames 35 serve to connect the limiting sleeve 36 and the cap 34. The inner upper edge of the limiting sleeve 36 is inclined to facilitate the insertion of the test tube 26.
[0023] The outer surface of the second magnet 31 is inlaid with a second housing 32. The second housing 32 is fixed to the side of the cap 34 and the side of one of the connecting brackets 35. The second housing 32 serves to fix the second magnet 31. The outer surfaces of the two first magnets 14 are each inlaid with a first housing 13. The first housing 13 serves to fix the first magnet 14. A rotating frame 12 is fixedly installed between the two first housings 13. A connecting sleeve 38 is inlaid through the middle of the rotating frame 12. The rotating frame 12 and the connecting sleeve 38 serve to connect the first magnet 14 and the drive shaft 11 together. The connecting sleeve 38 is inlaid at the upper end of the drive shaft 11.
[0024] A shaft bracket 8 is rotatably mounted on the lower end of the drive shaft 11. An L-shaped bracket 7 is fixedly mounted on the side of the shaft bracket 8. The shaft bracket 8 serves to support the drive shaft 11 and the drive shaft 10. A motor bracket 6 is fixedly mounted on the end of the L-shaped bracket 7. The motor bracket 6 is fixed to the side of the Raman spectrometer 1. A servo motor 5 is fixedly mounted on the end of the motor bracket 6. The motor bracket 6 serves to fix the servo motor 5. A drive shaft 10 is coaxially fixedly mounted on the output end of the servo motor 5. The drive shaft 10 is rotatably mounted through the end of the shaft bracket 8. A small gear 9 is coaxially rotatably mounted on the upper end of the drive shaft 10. A large gear 15 is coaxially fixedly mounted on the middle of the outer surface of the drive shaft 11. 15 meshes with the small gear 9, and the large gear 15 plays a transmission role with the small gear 9. A reinforcing frame 37 is fixedly installed at the corner of the L-shaped frame 7. The reinforcing frame 37 plays a role in improving the load-bearing strength of the L-shaped frame 7. Limiting ears 22 are provided on both sides of the limiting sleeve 36. The upper end of the limiting ear 22 is inlaid with an ear bracket 23. The ear bracket 23 plays a role in fixing the limiting ear 22. The limiting ear 22 plays a role in limiting the swing amplitude of the test tube 26. The end of the ear bracket 23 is fixed to the inner surface of the receiving cavity 24. The lower end of the limiting ear 22 is inclined so as to fit and adapt to the end face of the connecting frame 35 after swinging, so that the connecting frame 35 and the limiting ear 22 can make full contact.
[0025] During testing, test tube 26 is inserted into limiting sleeve 36. At this time, cap 34 is attached to the bottom of test tube 26 to limit and support it. Then, servo motor 5 drives drive shaft 10 to rotate, which in turn drives two magnets 14 on transmission shaft 11 via pinion 9 and gear 15 to rotate. This continuously changes the position of the two magnets 14, so that the magnets 14 attract and repel magnets 31, causing the magnets 14 to continuously attract and repel magnets 31. This magnetic force causes test tube 26 in limiting sleeve 36 to swing left and right, mixing the blood sample and saline solution inside. Then, pull ring 17 is pulled to... The limiting post 16, pushed out by the fixed spring 18, is pulled out from the limiting hole 20 and then pushes the tube seat 25. At this time, the guide ridge 4 slides in the guide groove 27 to assist the tube seat 25 in moving so as to send the test tube 26 to the detection position. At this time, the limiting magnet 29 and the positioning magnet 30 attract each other, keeping the test tube 26 in an upright state. Then, the detection end of the Raman spectrometer 1 emits detection light to detect the blood sample in the test tube 26. During this process, another test tube 26 to be tested can be placed in the limiting sleeve 36 at the other end of the tube seat 25 to shake the test tube 26, which is to prepare for the test. After the previous test tube 26 has been tested, the test tube 26 can be directly pushed to the detection position for testing. This cycle is repeated continuously.
