[0002] Pharmacy is a healthcare industry that connects health science and chemical science. It is responsible for ensuring the safe and effective use of drugs. Pharmacy mainly studies the source, preparation, properties, effects, analysis, identification, preparation, production, storage and search (including synthesis) of new drugs. In pharmaceutical experiments, sampling equipment plays a vital role. It is responsible for accurately and efficiently extracting drug samples for subsequent analysis and testing.

[0003] Traditional sampling equipment often lacks precise sampling volume control mechanisms, resulting in inaccurate sampling volume, which in turn affects the reliability of test results. In addition, the stability and fixity of the equipment is also a key issue. During the sampling process, if the sampling equipment cannot firmly fix the sampling bottle, it needs to be supported by staff, which increases the difficulty of sampling. Moreover, since the sampling components are usually fixed and cannot be easily disassembled and replaced, this greatly reduces work efficiency when the sampling components need to be frequently replaced or cleaned and disinfected.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a sampling device for pharmaceutical testing is proposed. Utility Model Content
