Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 and 2, a suction device for detecting bacterial strains experiments, includes barrel 1, disposable toper pipette 2 and butt joint pipe 3, spacing sliding sleeve 5 is installed through the mounting bracket in the barrel 1 outside, 1 top cover of barrel is equipped with n

shape action bars

4, 4 bottoms of n shape action bars are connected with piston block 9 through the thread groove, piston block 9 is located inside barrel 1, the bottom has stainless steel wire net 10 through the bolt fastening in

barrel

1, 1 bottom hot melt of barrel is connected with butt joint pipe 3, the inside veneer of butt joint pipe 3 has waterproof ventilated membrane 11, disposable toper pipette 2 is equipped with to the 3 outside cover of butt joint pipe, disposable toper pipette 2 one side engraving has scale 6.

One end of the n-shaped operating rod 4 is connected with a push block 8 in a hot melting mode, and the n-shaped operating rod 4 penetrates through the limiting sliding sleeve 5.

In this embodiment, as shown in fig. 1, a person can push the n-shaped operating rod 4 through the push block 8, and the limiting sliding sleeve 5 can limit the n-shaped operating rod 4.

A clamping block 12 is connected to the outer side of the butt joint pipe 3 in a hot melting mode, and a clamping groove 13 corresponding to the clamping block 12 is formed in the inner side of the disposable conical pipette 2.

In this embodiment, as shown in fig. 2 and 3, the fixture block 12 and the clamping groove 13 facilitate the disposable conical pipette 2 to be sleeved outside the docking pipe 3.

Wherein, the bottom end of the disposable conical pipette 2 is connected with an eagle hook pipette nozzle 7 in a hot melting way.

In this embodiment, as shown in fig. 1, the eagle hook pipette tip 7 facilitates the disposable conical pipette 2 to suck the strain.
