[0002] The quantum dot fluorescence immunoassay analyzer is a biomedical detection device based on fluorescence immunoassay technology. It is widely used in clinical diagnosis and biomedical research. It uses quantum dots as fluorescent markers to combine with the target substance in the sample to be tested through a specific immune reaction, and then detects and analyzes the fluorescence signal to achieve quantitative or qualitative detection of the target substance.

[0003] When performing detection operations, the quantum dot fluorescence immunoassay analyzer in the prior art requires the user to insert a reagent card into the analyzer. However, the traditional reagent card design often lacks a stable fixing mechanism after insertion, which leads to problems such as shaking or falling off in actual use. This unstable situation may not only affect the accuracy of the detection operation, but also cause deviations in the test results, thereby causing many inconveniences to the user.

A plug block 14 is slidably installed inside the second plug hole 13, and the bottom end of the plug block 14 extends to the outside of the second plug hole 13. A second inclined surface that is in sliding contact with the inclined surface of the trapezoidal block 8 is provided at the bottom of the plug block 14. The second inclined surface is convenient for sliding contact with the inclined surface of the trapezoidal block 8, which can facilitate the automatic movement of the extension plate 3. The inner top wall of the second plug hole 13 is fixed There is a second spring 15, and the bottom end of the second spring 15 is fixed to the top of the plug-in block 14. When in use, the extension plate 3 is pulled outward to move the extension plate 3 to the outermost side. At the same time, the second inclined surface on the plug-in block 14 slides in contact with the inclined surface of the trapezoidal block 8, and finally the plug-in block 14 contacts the top wall of the trapezoidal block 8. The plug-in block 14 squeezes the trapezoidal block 8, so that the portion of the extension plate 3 extending to the outside of the plug-in slot 2 can be stably fixed, and then the agent card is placed on the extension plate 3. Due to the elastic force of the first spring 12, the clamping block 11 is driven by the first plug-in rod 10 to clamp the agent card After fixing and installing, the extension plate 3 is pushed into the insertion slot 2, and at the same time, the second inclined surface on the insertion block 14 is in sliding contact with the inclined surface of the trapezoidal block 8. Because of the elastic force of the second spring 15, the insertion block 14 is driven to move downward, and the insertion block 14 pushes the trapezoidal block 8 to move to one side, thereby driving the agent card on the extension plate 3 to move to the inner side of the insertion slot 2, and at the same time, a force is applied to the agent card to move to the inner side of the insertion slot 2, thereby improving the stability and firmness of the agent card fixation, preventing the agent card from loosening during work, and effectively preventing the agent card from being accurately and stably inserted into the end of the insertion slot 2 by manual operation;

[0019] like Figure 1-2 As shown, a through slot 6 is provided on one side of the extension plate 3, which is convenient for pinching the dosage card on the extension plate 3, so as to remove the dosage card from the extension plate 3, which is more practical and convenient;

[0020] like Figure 1-2 As shown, the outer wall of the extension plate 3 and the two sides of the through slot 6 are fixed with stoppers 7, which are convenient for limiting the dosage card, so that the dosage card can be stably inserted into the insertion slot 2 to avoid the dosage card from loosening, thereby improving the accuracy of the measurement, which is more practical;

[0024] The working principle of the utility model is as follows: when in use, the extension plate 3 is pulled outward to move the extension plate 3 to the outermost side. At the same time, the second inclined surface on the plug-in block 14 slides in contact with the inclined surface of the trapezoidal block 8, and finally the plug-in block 14 contacts the top wall of the trapezoidal block 8, and the plug-in block 14 squeezes the trapezoidal block 8, so that the part of the extension plate 3 extending to the outside of the plug-in slot 2 can be stably fixed, and then the agent card is placed on the extension plate 3. Because of the elastic force of the first spring 12, the clamping block 11 is driven by the first plug-in rod 10 to clamp and fix the agent card. After installation, the extension plate 3 is pushed into the plug-in slot 2. At the same time, the second inclined surface on the plug-in block 14 slides in contact with the inclined surface of the trapezoidal block 8. Because of the elastic force of the second spring 15, the plug-in block 14 is driven to move downward, and the plug-in block 14 pushes the trapezoidal block 8 to one side, thereby driving the agent card on the extension plate 3 to move toward the inner side of the plug-in slot 2, and at the same time, a force is applied to the agent card to move toward the inner side of the plug-in slot 2.
