Detailed Description

The present application is described in further detail below with reference to figures 2-4.

The embodiment of the application discloses a biological sampling pipe. Referring to fig. 2, a biological sampling pipe includes body 1 and lid 2, and lid 2 threaded connection is at body 1 lateral wall.

Referring to fig. 2 and 3, an elastic ring plate 21 is fixedly connected to the inner top wall of the cover body 2, the inner diameter of the elastic ring plate 21 is gradually reduced along the direction from the pipe body 1 to the cover body 2, and a space for embedding the opening of the pipe body 1 is formed between the elastic ring plate 21 and the inner side wall of the cover body 2.
