[0002] The design of a pesticide quality inspection sample extraction device aims to efficiently and accurately extract samples from pesticide products for quality inspection analysis. During the production and sales of pesticides, it is necessary to conduct sampling inspections on the products. Through sampling inspections, illegal activities such as the production and sale of banned pesticides, counterfeit and substandard pesticides, and hidden additives of pesticides can be combated, the pesticide market order can be regulated, and a fair competitive market environment can be maintained.

[0003] The existing Chinese utility model patent with application number CN200920290423.6 relates to an anti-clogging pesticide extractor, which includes a push rod, a storage cylinder, a sealing plug, a hose, a suction head, and an opening. It can prevent the suction head from clogging and has high pesticide dispensing accuracy, thus effectively exerting the pesticide's efficacy.

[0004] However, the above-mentioned devices do not have the ability to provide shade in actual use. Many pesticides usually need to be stored away from light. These pesticides are prone to decomposition under light conditions, which reduces the effective ingredients of the pesticides and affects the quality inspection results. In addition, the suction head of the above-mentioned devices is not airtight and is prone to leakage during movement. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a pesticide quality inspection sample extraction device that extracts and stores pesticides using an extraction device, is easy to disassemble and connect, seals the extraction device with a sealing device to reduce pesticide leakage during movement, and minimizes the impact of external sunlight on the pesticides. A limiting device adjusts and fixes the position of the extraction device within the sealing device, facilitating extraction of pesticides from the bottle opening, thus improving the device's practicality.

[0006] This utility model discloses a pesticide quality inspection sample extraction device, comprising an extraction device, a sealing device, and a limiting device. The sealing device is installed on the extraction device, and the limiting device is installed on the sealing device. The extraction device extracts and stores pesticides and facilitates disassembly and reassembly. The sealing device seals the extraction device, reducing pesticide leakage during movement and minimizing the impact of external sunlight on the pesticides. The limiting device adjusts and fixes the position of the extraction device within the sealing device, facilitating deeper extraction of pesticides from the bottle opening, thus improving the practicality of the device.

[0007] Preferably, the extraction device includes a pesticide storage cylinder, a piston head, a connecting seat, a connecting rod, a threaded connector, and an internal threaded hole.
