The working principle is as follows:

the specific use mode and action of the embodiment are that firstly, the motor inside the main body 1 is turned on to drive the screw 2 inside the main body to rotate, when the screw 2 starts to rotate, the screw is driven to rotate coaxially through the tooth marks on the surface of the male rotor 201 and the tooth marks on the surface of the female rotor 202, the high-speed rotation of the screw and the male rotor drives the air flow to rotate and compress, then the compressed air flow is discharged and conveyed for use through the exhaust pump 101, when the male rotor 201 on the screw 2 rotates, the transmission gears 203 at the two ends of the screw also rotate together, when the rotating speed reaches a certain rotating speed, the transmission gears 203 generate centrifugal force to the surrounding transmission gears 203 to force and expand the surrounding transmission gears 203 because the middle parts of the transmission gears are hollow, when the transmission gears 203 expand, the expansion blocks 2041 in the expansion layer 204 are exposed and expanded together, the diameter of the transmission gear 203 is increased by extending the extension block 2041 so that the transmission gear 203 can be extended to the periphery under the action of centrifugal force, and the extension rod 205 connected to the middle part is stretched and stretched to stably extend the transmission gear 203, when the transmission gear 203 is extended, the transmission gear can push the female rotor 202 to move to one side by pushing against the secondary gears on two sides of the female rotor 202 on one side, so that a certain gap is formed between the female rotor 202 and the male rotor 201, the transmission gear 203 is meshed with the secondary gears on two sides of the female rotor 202 to drive the secondary gears to rotate and pressurize, the direct contact area between the male rotor 201 and the female rotor 202 is reduced to reduce friction and noise and vibration, and finally, when the transmission gear 203 is forced to be extended to the periphery so that the extension block 2041 is extended, the extension block 2041 is deflected and corrected, when the deviation correction is performed, the circular shaft with one end connected moves along the displacement groove 2042 according to the deviation thereof until the circular shaft moves into the circular groove at one end of the displacement groove 2042, so that one end of the expansion block 2041 is completely attached to one side of the expansion layer 204, and the other end of the expansion block 2041 moves and deviates at one side of the middle part of the expansion layer 204 through the circular shaft for connection, so that the whole expansion block 2041 can extend to the surface of the transmission gear 203 to increase the diameter of the transmission gear 203, and simultaneously, when the rotation speed of the screw 2 is reduced, the transmission gear 203 can contract due to the pulling of the spring inside the extension rod 205, and meanwhile, the expansion block 2041 is embedded in the bundling ring 2062 through the bundling block 2043 at the bottom end, and the bundling block 2043 is driven to be embedded into a part of the bundling ring 2062 through the rotation of the bundling ring 2062, so that the expansion block 2041 can be biased and pulled in the contraction process of the transmission gear 203 to be embedded into the expansion layer 204 again for overlapping and overlapping Meanwhile, since the tightening ring 2062 and the rotating ring 206 are connected through the fitting ring 2061, when the fitting ring 2061 rotates, a certain friction force is increased because the circular shaft on one side of the fitting ring is fitted in the tightening ring 2062, so that the rotating speeds of the tightening ring 2061 and the tightening ring are inconsistent, and the expansion block 2041 can be forced to contract earlier than the transmission gear 203 to prevent the expansion block 2041 from being blocked when the transmission gear 203 contracts.
