The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] First embodiment:

[0024] See also Figure 1 to Figure 3 ,in Figure 1This is a front view of the first embodiment of the utility model. Figure 2 The utility model Figure 1 The cross-sectional view along the AA line. Figure 3 The utility model Figure 2 A partial enlarged view of point B in the middle.

The above-mentioned solution solves the technical problem that when replacing a single reagent tube 106, the entire top cover 103 needs to be opened, and the opened top cover 103 will remove multiple extrusion mechanisms from the corresponding reagent tube 106, which will easily cause foreign impurities to fall into other reagent tubes 106, thereby affecting the detection results.

[0026] According to this specific embodiment, a top cover 103 is hingedly provided on the top of the detection device 101, and a plurality of threaded grooves 104 are provided on the top of the top cover 103. The detection device 101 has a plurality of reagent storage and inspection slots 105, and a reagent tube 106 is provided in the reagent storage and inspection slots 105. The plurality of detection devices 101 are respectively fixedly connected to the device body 102 and are located on the upper end surface of the device body 102. By placing the reagent tube 106 in the reagent storage and inspection slot 105, the detection device 101 is operated through the top cover 103. It should be noted that the detection device 101 and the device body 102 are prior arts, and their working principle is to adopt continuous detection method and enzyme inhibition principle; when organophosphorus and carbamate pesticides are present, they will inhibit the normal function of cholinesterase, and this inhibition rate is proportional to the concentration of pesticides; under normal circumstances, cholinesterase can catalyze the hydrolysis of neurotransmitters; its hydrolysis product reacts with the color developer to produce a yellow substance, and by measuring the absorbance change of the yellow substance, the inhibition rate of enzyme activity can be calculated, and then it can be judged whether the sample contains residues of the above two types of pesticides.

[0027] Among them, the plurality of auxiliary mechanisms are respectively arranged between the corresponding thread grooves 104 and the reagent storage and inspection grooves 105, the outer side of the rotating block 108 has threads, the extrusion assembly 107 is slidably connected to the rotating block 108 and is located in the middle of the rotating block 108, the extrusion assembly 107 is also mutually supported by the corresponding reagent tube 106, and is located above the reagent tube 106, and is also located in the reagent storage and inspection groove 105, the two rotating parts are respectively fixedly connected to the rotating block 108, and are symmetrically arranged It is placed above the rotating block 108, and the rotating block 108 is threadedly connected to the top cover 103 and is located in the corresponding thread groove 104. By opening the thread groove 104 on the top cover 103, the extrusion assembly 107 is set on the rotating block 108, and the rotating block 108 is threadedly set in the thread groove 104, so that a single reagent tube 106 can be easily taken out without opening the top cover 103, thereby ensuring that impurities will not fall into other reagent tubes 106.

[0028] Secondly, the limiting plate 109 is fixedly connected to the rotating block 108 and is located on the outside of the rotating block 108. The limiting plate 109 also abuts against the top cover 103 and is located above the top cover 103. The limiting plate 109 can limit the downward movement distance of the rotating block 108, thereby preventing the rotating block 108 from causing crushing injuries to the reagent tube 106.

[0029] Again, a rotating rod is provided at one end of the handle 110, and the rotating rod is rotatably connected to the corresponding support block 111 and is located between the two support blocks 111. The two support blocks 111 are respectively fixedly connected to the rotating block 108 and are symmetrically arranged above the rotating block 108. By rotatably setting the handle 110 between the two support blocks 111, it is convenient to store the rotating block 108 after rotating it.

[0030] When using the utility model to take out a single reagent tube 106, the two handles 110 are used to rotate the rotating block 108 counterclockwise to move the rotating block 108 out of the thread groove 104, and drive the extrusion assembly 107 to move out together. At this time, the reagent tube 106 to be replaced can be taken out through the thread groove 104, and then a new reagent tube 106 is replaced, and the rotating block 108 is placed in the thread groove 104, so that the extrusion assembly 107 is pressed against the upper surface of the reagent tube 106. Finally, rotate the rotating block 108 clockwise to make the rotating block 108 enter the threaded groove 104, and the replacement can be completed when the limiting piece 109 abuts against the top cover 103. In this way, the technical problem that when replacing a single reagent tube 106, it is necessary to open the entire top cover 103, and the opened top cover 103 will remove multiple squeezing mechanisms from the corresponding reagent tube 106, which will easily cause foreign impurities to fall into other reagent tubes 106, thereby affecting the detection results is solved.

When the top cover 103 needs to be fixed, continue to pull the fixing rod 203, and then cover the top cover 103 on the detection device 101. At this time, the fixing rod 203 is loosened, and the fixing rod 203 is automatically inserted into the outside of the detection device 101 under the action of the limit ring 202 and the fixing spring 201, thereby completing the fixation.

[0036] Secondly, the extrusion spring 205 is sleeved on the slide bar 207 and is held between the pressure block 206 and the rotating block 108.
