Furthermore, the mutual communication between the first air pipe 51 and the second air pipe 52 and the first communication pipe 41 and the second communication pipe 41 is completed respectively. Subsequently, the air extraction component 11 is started to perform gas sampling. After the sampling work is completed, the turntable 3 is pushed to rotate again to enable the first arc-shaped docking block 43 and the second arc-shaped docking block 63 to gradually separate from contact. The movable pipe 61 is reset under the action of the elastic member, and the rubber block 62 is closed under the action of the elastic force, thereby realizing the automatic closing of the communication valve 6, and the air sampling work at this sampling point can be completed. Subsequently, when the air sampling work at the next position is carried out, the connection and switching of the collection bottle 5 are quickly carried out in the same principle as above.
