A sealing plate 9 is provided on the installation groove. A locking mechanism is provided between the sealing plate 9 and the detection card body 1. In this embodiment, the locking mechanism is used to remove the sealing plate 9 from one side of the detection card body 1, and then the lifting column 5 is pressed downward. The lifting column 5 stably moves downward in the adjustment groove through the guiding mechanism. The lifting column 5 drives the adjustment plate 6 to move downward, so that the elastic member 7 between the adjustment plate 6 and the adjustment groove is squeezed and deformed. The fastening plate 8 on the adjustment plate 6 moves downward in the fastening groove. Then the detection test strip 4 is inserted into the installation groove, and the detection card body 1 is tilted, so that the detection test strip 4 abuts against one side of the installation groove by gravity. Then the lifting column 5 is released. At this time, the elastic member 7 supports the adjustment plate 6, and the adjustment plate 6 drives the lifting column 5 and the fastening plate 8 to reset, so that the fastening plate 8 presses the detection test strip 4 against the installation groove, and the detection test strip 4 is fixed. Then by rotating the threaded column 3, the threaded column 3 is removed from the threaded hole, and the personnel put the sample liquid through the threaded hole, so that the chlorpyrifos in the sample binds to the pre-labeled colloidal gold antibody. These conjugates will move along the cellulose membrane to reach the detection line. The detection test strip 4 is a common test strip for chlorpyrifos detection in the prior art and will not be described in detail in this structure. By observing the detection line of the detection test strip 4 through the transparent plate 2 of the observation port, the purpose of detecting chlorpyrifos is achieved. When not in use, the threaded column 3 is arranged in the threaded hole, and the installation groove is sealed by the sealing plate 9, so that the detection test strip 4 can be sealed and fixed in the installation groove, and the detection test strip 4 can always be in a state of high cleanliness. Through high cleanliness, it can be ensured that the detection test strip 4 is always in a state of high sensitivity and will not be affected by external dust, etc., which is convenient for carrying the detection card body 1 to more application scenarios to detect chlorpyrifos efficiently, highly sensitively and with high precision.
