When the first L-shaped plate 13 is thrusted by the inner wall of the first through hole 12, the connecting disk 11, the adapting sleeve 10, and the second sealing plate 8 are driven to rotate as a whole. At this time, the second sealing plate 8 and the first sealing plate 7 are reversed, so that the gas can enter through the space between the second sealing plate 8, the first sealing plate 7 and the inner wall of the mounting tube 1, and be received by the flow meter 2 for detection. By means of the above structure, the overall control of the airflow rate can effectively prevent the occurrence of airflow backflow.
