State the extension being equipped in tube body for being inserted into the hollow cavity 4.
It is using the advantageous effect of above-mentioned technical proposal：
Since 3 one end of thief rod in the present embodiment excrement quantitative sampling device is equipped with hollow cavity 4, the hollow cavity 4
Volume can be preset according to the requirement of sampling amount, thief rod more than 3 times, which is inserted into excrement and can realize in hollow cavity 4, fills up excrement
Just, then thief rod 3 is stretched into collecting pipe 2, equipped with protection liquid in collecting pipe 2, the process of collecting pipe 2 is stretched into thief rod 3
In, extension is gradually inserted in hollow cavity 4, is made between excrement via through holes 5 or extension and the hollow cavity 4 in hollow cavity 4
Gap squeezes out, and is sufficiently mixed with the protection liquid in collecting pipe 2.
It includes thief rod 3 and collecting pipe 2 to have discussed excrement quantitative sampling device above, detailed with reference to Fig. 1 to Fig. 3
Two component expansion of fine needle pair are described in detail.
(1) thief rod 3
3 one end of thief rod is equipped with hollow cavity 4, and the hollow cavity 4 is for acquiring excrement, it can be understood as sampling cavity.
During thief rod 3 stretches into collecting pipe 2, one end equipped with hollow cavity 4 is first stretched into through opening in tube body.
The outer wall of the hollow cavity 4 is equipped with the through-hole 5 communicated therewith, and the quantity of through-hole 5 is unlimited, and shape is also not limited to
The shape of circle shown in figure, hollow cavity 4 is also not limited to cylinder shown in figure, and through-hole 5 can be along hollow cavity 4
Outer wall is arranged in arrays, and excrement is facilitated to be discharged from different through-holes 5.
During stretching into collecting pipe 2, thief rod 3 is gradually moved down along the direction close to 2 bottom of collecting pipe thief rod 3,
Since extension corresponds to hollow cavity 4, then extension can be gradually inserted hollow cavity 4.It is inserted into the mistake of hollow cavity 4 in extension
Cheng Zhong makes gap between excrement via through holes 5 or extension and hollow cavity 4 be detached from hollow cavity based on extension and excrement interaction
Body 4, the protection liquid for making excrement be soluble in collecting pipe 2.
Stretching into or deviate from and the sealing of collecting pipe 2 for the ease of thief rod 3, the utility model can also include pipe
Lid 1, the pipe lid 1 are connect with thief rod 3, and when thief rod 3 finally stretches into collecting pipe 2, and lid closes the opening of collecting pipe 2.
(2) collecting pipe 2
Other than collecting pipe 2 discussed herein above is to be additionally provided with extension in the tube body with opening and tube body, the extension
The shape of part can change according to actual needs, it is only necessary to meet extension be inserted into hollow cavity 4 during based on extension with
Excrement interaction makes gap between excrement via through holes 5 or extension and hollow cavity 4 be detached from hollow cavity 4.
The extension can extend along close to the direction of opening, the extension when hollow cavity 4 is stretched into through opening in collecting pipe 2
It is gradually inserted hollow cavity 4.Extension can be the solid cylinder structure 6 in Fig. 1；Can also be the cylindrical structure in Fig. 2, outside
