Problems solved by technology

[0002] There are many testing items for drug testing, including drug quality testing, drug composition testing, drug heavy metal testing, drug adverse reaction testing, drug tightness testing, biological drug testing, drug appearance testing, drug routine testing, drug physical and chemical testing, drug safety testing and Drug defect detection, the purpose of drug testing is to prevent unqualified drugs from entering the market and ensure the safety of drugs. In the process of sampling drugs in the existing drug testing and sampling devices, if drugs (especially powder) are stacked in the container If it is high, it is necessary to sample different parts of the upper, middle and lower parts, and the existing sampling device cannot accurately control the sampling position; in addition, the drug is easy to stick to the inside of the sampling device during the sampling process, and some drugs are not easy to remove after sticking Clean, resulting in the contamination of the last drug in the next test of different drugs, which will affect the quality of the test
