The inward movement of the movable frames 5 drives the connecting piece 504 connected to the connecting rod 502 on the movable frame 5 to rotate, so that it generates an outward force, driving the distance between the two groups of relative clamping plates 6 to be pulled apart. At this time, the gripping part 301 at the top of the sampling rod 4 is held by hand to remove the sampling rod 4 from the placement cavity 101 of the sampling tube 1, and then the sampling head 201 at the bottom of the sampling rod 4 is used for medical or experimental operations; when the sampling is completed, the sampling rod 4 is put back in the opposite way. The device realizes the effective isolation of the sampling head 201 and the placement cavity 101 in the sampling tube 1 from the external environment through the design of the upper cover 3, the lower cover 2 and the closing component, effectively preventing the contamination of the sample by external microorganisms, thereby reducing the risk of sample contamination.
