In the process of agricultural product quality monitoring, the residual amount of pesticides in agricultural products is an important indicator and is closely related to the quality of agricultural products. When testing agricultural products for pesticide residues, the agricultural products to be tested are first cut into small pieces that are convenient for placing into the test tube, a certain weight of sample is taken and placed in a sample bottle, a certain amount of buffer is added to the sample bottle, and after oscillation, it is allowed to stand for a period of time to take a certain amount of supernatant, and then further reagents are added, and finally the sample is placed in a pesticide detector for testing.

[0003] However, when existing oscillators used for agricultural product sampling oscillate the clamped test tube, most of them directly generate vibration through the oscillator and then transmit it to the test tube, causing the test tube to vibrate and shake evenly. The contact points between the test tube and the clamp will constantly move relative to each other, thereby generating friction, which can easily cause damage to the test tube itself, such as wear and cracks, increasing the risk of test tube damage.
