The adjusting member 220 is disposed on the containing member 100, and the adjusting member 220 is transmission-connected to the clamping plate 210 to adjust the clamping distance between the containing cavity 110 and the clamping plate 210.

[0035] With the above structure, the clamping plate 210 can move in the holding chamber 110, which means that the clamping plate 210 can be adjusted relative to the inner wall of the holding chamber 110 to form an appropriate clamping distance, so that the sampling bottle can be clamped at the clamping distance. The adjusting member 220 can be connected to the clamping plate 210 through a certain mechanical transmission structure to adjust the clamping distance between the holding chamber 110 and the clamping plate 210, thereby adjusting the force or position of clamping the sampling bottle. The structure is simple and has a wide range of adaptability to be suitable for sampling bottles of different diameters.
