[0044] In the present technical solution, the position of the piston rod 402 can be adjusted by filling the fixed tube 401 with air. When the gas enters the fixed tube 401, the air pressure generated pushes the movable plug 403 downward, so that the movable plug 403 drives the piston rod 402 and the connecting block 404 downward, and the connecting block 404 drives the movable tube 406 and the flow equalizer 407 to move downward synchronously, so that the width of the overflow groove 408 formed between the flow equalizer 407 and the guide column 204 changes, and a part of the airflow entering the sleeve 301 is discharged from the overflow groove 408. 8, and the rest of the airflow is evenly discharged from the flow equalizer 407, so that the airflow circulates evenly inside the sliding sleeve 302. When it is necessary to move the piston rod 402 upward, the gas in the fixed tube 401 is discharged. At this time, the spring 405 in the stretched state is reset and drives the movable tube 406 and the flow equalizer 407 to move upward, so that the position of the flow equalizer 407 can be adjusted according to the needs of the airflow, so that part of the airflow flows from the surface of the guide column 204, and the airflow evenly distributed inside the sliding sleeve 302 is mixed at the gap 306, so as to realize the efficient discharge of the airflow.
