[0037] Working principle: When the device is needed to detect small molecules, the liquid is added into the mixing barrel 2 through the feed pipe 3. At this time, the motor 4 is started and the one-way valve 17 is opened. The rotation of the motor 4 can drive the transmission rod 11 to rotate, and the transmission rod 11 will also drive the active bevel gear 12 to rotate when it rotates. At this time, the active bevel gear 12 meshes with the driven bevel gear 13 so that the driven bevel gear 13 rotates. When the driven bevel gear 13 rotates, the rotating rod 14 drives the stirring plate 15 to rotate, thereby mixing the liquid medicine inside the mixing barrel 2 to make the liquid medicine uniform. When the transmission rod 11 rotates, it will also drive the rotating disk 5 to rotate. At this time, the rotation of the rotating disk 5 brings As the extension column 6 rotates, the rotation of the extension column 6 can push the rotating ring 7 to move the connecting rod 8. At this time, the movement of the connecting rod 8 can push the pushing plate 9 to slide on the inner wall of the discharge barrel 10, so that the medicine liquid inside the discharge barrel 10 is discharged from the discharge pipe 18 and enters the vessel 32. During the process, the motor 2 30 is started to drive the supporting plate 31 to rotate, so that the supporting plate 31 drives the vessel 32 to move, so that multiple vessels 32 can be added, and the cylinder 21 is started to drive the mounting plate 22 to make the detection head 23 detect the medicine liquid in the vessel 32, so that under the rotation of the vessel 32 and the detection of the detection head 23 driven by the cylinder 21, multiple samples can be detected to ensure the accuracy of the detection results.

[0038] Finally, when the detection head 23 needs to be cleaned or replaced, the sliding column 25 is pulled, and the movement of the sliding column 25 can drive the limiting block 27 to move. At this time, the movement of the limiting block 27 can squeeze the spring 26, so that the limiting block 27 is deformed to generate elastic potential energy. At this time, the movement of the limiting block 27 will also drive the clamping block 28 to move. At this time, the clamping block 28 will exit the through hole of the extension block 24, so that the detection head 23 can be rotated. At this time, the rotation of the detection head 23 can drive the extension block 24 to rotate so that the extension block 24 slides on the inner wall of the slot 29. When the closing position is reached, When it is in the appropriate position, the detection head 23 can be pulled out from the bottom of the mounting disk 22 to complete the disassembly. When it needs to be installed, pull the sliding column 25, and then insert the detection head 23 into the bottom of the mounting disk 22, so that the extension block 24 slides from the recess of the mounting disk 22, and then rotate the detection head 23 to make the extension block 24 slide on the inner wall of the slot 29. When it reaches the appropriate position, release the sliding column 25, which will cause the spring 26 to release its elastic potential energy, thereby pushing the limiting block 27 to drive the card block 28 to reset. When the card block 28 is reset, it can engage with the through hole of the extension block 24, thereby completing the installation.
