Further, a spring plate groove is formed in the bottom of the clamping groove, and one end of the positive pressure spring plate is installed in the spring plate groove. The spring piece groove can provide deformation space for the positive pressure spring piece, and the bottom of the clamping groove is scraped by the positive pressure spring piece.

Further, the positive pressure shrapnel is installed on the lower bracket of the cassette through a screw, and a screw assembly mode is adopted, so that the cassette is simple and convenient.

Further, the tail end of the clamping groove is an insertion depth limit stop. The depth limit stop is used for limiting the insertion depth of the test card.

Further, the cassette lower bracket is also provided with an inserting slot which is arranged behind the inserting depth limit stop. The inserting sheet groove is used for placing a trigger switch, and after the test card is inserted into the preset position, the trigger switch is pressed so that the fluorescence immunoassay analyzer starts to work.

By adopting the scheme, the utility model provides the detection card positioning structure of the fluorescence immunoassay analyzer, in the process of inserting the test card into the clamping groove, the positive pressure spring piece clamps the test card together with the height limiting plate, meanwhile, the spring thimble pushes the test card towards one side of the clamping groove, after the test card is inserted into the preset position, the test card also completely leans against one side of the clamping groove, and is clamped by the positive pressure spring piece and the height limiting plate, so that the test card is limited to an accurate position, an operator is not required to draw the test card towards one side of the clamping groove, the accurate insertion position of the test card is ensured, the insertion of the test card is avoided, and no deviation of the detection result is ensured.
