Description

Technical Field

[0001] The utility model relates to the technical field of pesticide quality detection, in particular to a pesticide quality detection and medicine dispensing device. Background Art

[0002] Pesticides refer to chemically synthesized substances or mixtures of several substances derived from biological or other natural substances and their preparations used to prevent and control diseases, insects, weeds, rodents and other harmful organisms that endanger agriculture and forestry, as well as to purposefully regulate the growth of plants and insects. After the pesticides are produced, a pesticide dispenser is needed to remove some of the pesticides for quality testing.

[0003] However, the existing medicine dispenser lacks the function of fixing the pull rod. During actual use, the pull rod is easily moved by accidental touch or external force, causing the sealing piston to move, thereby causing the pesticide in the medicine barrel to flow out, making it inconvenient to use and requiring the medicine to be taken again, which increases labor intensity.
