[0002] Pesticide residues refer to the general term for pesticide parent substances, derivatives, metabolites and impurities that remain in the environment, organisms and food after the use of pesticides. The instrument that can detect residual pesticides is called a rapid pesticide residue detector.

[0003] During the agricultural product cultivation process, pesticides are generally sprayed to prevent pests. However, when the crops are finally eaten by people, there may be residual pesticides left on the crops. Therefore, after picking the crops, a detection device is generally used to detect residual pesticides. Existing pesticide residue detection devices generally pour the reaction liquid and the tested crops and then wait for the reaction results to determine whether there are pesticide residues. This will result in insufficient contact between the reaction liquid and the crops, which will not only prolong the test time and slow down the work efficiency, but also lead to errors in the final test results.

[0026] Reference Figure 3The outer side of the surface of the movable column 202 is fixedly connected to a limiting ring 203. The diameter of the limiting ring 203 is larger than the diameter of the movable column 202. The inner side of the limiting ring 203 is movably connected to the outer side of the fixed plate 204. The limiting ring 203 is set so that the movable column 202 will not be separated from the fixed plate 204 when it moves in the inner cavity of the fixed plate 204, thereby limiting the movable column 202.

[0027] Reference Figure 3 The bottom of the motor 205 is fixedly connected to a bracket 210, and the front side of the bracket 210 is fixedly connected to one side of the inner cavity of the box 101.

At the same time, the movable plate 214 will drive the mounting chamber 209 to shake, and the mounting chamber 209 will drive the movable column 202 to shake left and right in the inner cavity of the fixed plate 204. At the same time, the movable plate 214 will drive the mounting plate 201 to shake, and then the fixing sleeve 102 will be driven to shake through the fixing sleeve 102, thereby driving the test tube 104 to shake through the fixing sleeve 102.
