[0019] Embodiment: Through the personnel in this field, all the electrical components in this case are connected to their adapted power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle. The electrical connection between the electrical components is completed in the working sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control. Please refer to Figure 1-3 The box body 1 and the box cover 2 form a closed space, and the disc rack can be disassembled on the connecting seat 8. When in use, the reagent tube containing the processed sample to be tested is placed in the reagent tube placement slot 11 on the disc rack outside the device, and then the box cover 2 is opened, and the disc rack is inserted into the connecting seat 8 through the positioning block 9, and then the box cover 2 is closed. At this time, one of the infrared transmitters 13 is aligned with the infrared receiver 6, and the photomultiplier tube 3 works, and acts on the sample reagent tube through the light hole 5 and the connecting hole 12 to detect the sample in the sample reagent tube. Then the motor 7 drives the connecting seat 8 in the avoidance hole. The disc rack rotates in the middle, and the disc rack rotates accordingly, until the next infrared transmitter 13 is aligned with the infrared receiver 6, and then the motor 7 stops rotating, and the samples that have not been tested are tested to achieve positioning detection, until all samples are tested. During the test, the user takes a new disc rack again and places other reagent tubes containing samples to be tested. After the sample test in the device is completed, the user opens the box cover 2, takes out the disc rack as a whole, and then puts the new disc rack into the box body 1 to directly carry out the test work, which improves the work efficiency of taking and placing the reagent tubes and shortens the waiting time for the test;

A plurality of support holes 16 are provided on the anti-tilt plate 15 in a circular array with the motor 7 as the center. The plurality of support holes 16 correspond to the plurality of reagent tube placement slots 11. The tray rack is taken by holding the hand-held rack 14, and the sample reagent tube is first inserted into the support hole 16 and then inserted into the reagent tube placement slot 11. The anti-tilt plate 15 supports the sample reagent tube to prevent the sample reagent tube from tipping over.

[0021] As a preferred embodiment, further, the positioning block 9 is a cross-shaped structure to prevent the support plate 10 and the connecting seat 8 from rotating relative to each other;

[0022] As a preferred embodiment, further, a shielding ring 17 is installed on the lower wall of the support plate 10, and the shielding ring 17 is located between the connecting hole 12 and the infrared emitter 13. When the positioning block 9 is inserted into the connecting seat 8, the shielding ring 17 is attached to the support plate 10 to isolate the infrared emitter 13 from the photomultiplier tube 3 to prevent the photomultiplier tube 3 from being affected;

[0023] Preferably, further, the diameter of the connecting hole 12 is smaller than the diameter of the reagent tube placement slot 11 to prevent the sample reagent tube from falling off;
