When compressed air enters the air distribution chamber 4 after pressure regulation by the pressure regulating valve 3, a reversing slide block 11 in the air distribution chamber 4 is a key part for controlling the piston 9 in the air cylinder 8 to move up and down. When the reversing slide block 11 is at the upper limit position, compressed air enters the annular chamber 6 through the air distribution 10 and the air inlet and outlet of the upper cylinder cavity corresponding to the air pump body 1 through the air inlet and outlet 15 of the lower cylinder cavity of the air distribution block 12, enters the upper cylinder of the piston 9 through the hollow piston rod 7, drives the piston 9 to move downwards, and residual air in the lower cylinder of the piston 9 is discharged through the air outlet 14 communicated with the groove of the reversing slide block 11 through the air distribution 10 and the air inlet and outlet 13 of the lower cylinder cavity corresponding to the air pump body 1. When the piston 9 moves downwards to a certain position, the annular ring 17 fastened by the piston rod 7 and the connecting rod 2 pushes the quick jump sleeve 5 to move downwards together, the downward movement of the quick jump sleeve 5 forces the reversing valve clack 18 supported by the reversing spring 20 and the reversing spring sleeve 19 in the spring seat 21 to change the swing angle downwards until the swing angle is lower than the horizontal center line, the quick jump sleeve 5 breaks away from the annular ring 17 to jump downwards under the action of the reversing spring 20 and the reversing valve clack 18, and when the quick jump sleeve 5 jumps downwards, the reversing slide block 11 is shifted to the lower limit position to switch the air inlet of the cylinder at the upper end of the original piston 9 and the air exhaust of the cylinder at the lower end of the piston 9 into the air inlet of the cylinder at the upper end of the original piston 9. The downward movement of the piston 9 is also changed to the upward movement due to the change of the intake and exhaust directions.
