[0002] In the field of pharmaceutical research, accurate sampling analysis and testing of medicines are key links for evaluating the quality, safety and effectiveness of medicines. For sampling of liquid medicines, the current common method is to use a syringe as a tool. The syringe sucks liquid medicines through the coordinated action of the syringe barrel, the piston rod and the piston to achieve the sucking and transferring of liquid.

[0003] In the specific operation, one hand holds the syringe barrel to ensure its stability, and the other hand pulls the piston rod to drive the piston to slide in the syringe barrel, thereby completing the extraction of liquid. However, this operation process is relatively complicated and inefficient because it requires the coordination of the operator's two hands, increasing the complexity of the operation. In addition, if the force is not properly controlled or the action is not smooth enough during the pulling of the piston rod, the amount of extracted liquid will deviate from the preset value, thereby damaging the accuracy of sampling.
