Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, an embodiment of the present utility model is provided:

the utility model provides a sample sampling device, includes sampling tube 1, and top cap 4 is installed to the upper end in the sampling tube 1, is provided with sealant 5 in the sampling tube 1, and the upper end of sealant 5 is connected with handle 7 through connecting rod 6, and the lower extreme of sampling tube 1 is provided with feed liquor pipe 9, and the syringe needle 10 is installed to the lower extreme of feed liquor pipe 9.

Further, the anti-slip pad 2 is sleeved on the outer surface of the sampling tube 1, and when the liquid medicine is extracted again, the sampling tube 1 is held, and the anti-slip pad 2 can be anti-slip.

Furthermore, the side surface of the sampling tube 1 is provided with a scale 3, and a certain amount of reagent can be extracted according to the requirement.
