During the sampling process of powdery drugs, spoons and other items are usually used to hold the drugs. However, during the use process, it is difficult to control the amount of drugs taken, and the taken powdery drugs still need to be poured into a container for storage. Moreover, during the process of taking out the powdery drugs, it is difficult to control the amount of powdery drugs taken out at one time, which is not convenient for detecting powdery drugs. Therefore, we propose a sampling equipment for the research and development and detection of powdery drugs. Content of the Utility Model

[0003] The purpose of the utility model is to provide a sampling equipment for the research and development and detection of powdery drugs to solve the above deficiencies in the technology.

A telescopic column is slidably connected to the inner wall of the top of the sampling cylinder. A reciprocating push rod is fixedly arranged on the outer wall of the top of the telescopic column. The top of the reciprocating push rod passes through one end of the top of the sampling cylinder and is fixedly provided with a pressing block. A compression spring is sleeved on the outer wall of the reciprocating push rod. A vertically downward positioning rod is fixedly arranged on the outer wall of the bottom of the telescopic column. A plurality of equally spaced limiting pieces are fixedly arranged on the outer wall of the positioning rod. The outer wall of the limiting piece is slidably connected to the inner wall of the sampling cylinder.

[0005] Preferably, a gasket is sleeved on the outer wall of the reciprocating push rod, and the gasket is located at the bottom of the compression spring.

[0006] Preferably, fixing plates are fixedly arranged on the outer walls of both sides of the top of the sampling cylinder, which is convenient for taking and controlling the utility model.

[0007] Preferably, an external thread groove is formed on the outer wall of the bottom of the sampling cylinder. A sealing tube is sleeved on the outer wall of the bottom of the sampling cylinder. An internal thread groove is screwed on the inner wall of the sealing tube. The internal thread groove is adapted to the sealing tube. By screwing the sealing tube on the outer wall of the bottom of the sampling cylinder, it is beneficial to improve the sealing effect of the sampling cylinder.

[0008] Preferably, the sampling cylinder and the internal thread groove are made of transparent plastic material, which is convenient for observing the powdery drugs stored in the sampling cylinder.
