after the axial rotation transmitted and input from the driving main shaft (22) is decelerated through the deceleration planetary gear box (23), the planet carrier (234) of the deceleration planetary gear box (23) drives the pin shaft at the bottom end to rotate, the pin shaft drives the cam connector (24) to rotate by taking the axial lead of the pin shaft hole (241) as the axis, and the swing rod (2511) is driven by the swing rod sleeving hole (242) to perform conical motion by taking the axial lead of the pin shaft hole (241) as the axis; under the conical motion of the rocking rod (2511), the movable plug (2512) of the rocking rod (251) reciprocates up and down in the piston hole (2521) of the silica gel piston (252).

6. The vacuum extractor of claim 5, wherein: the movable plug (2512) is provided with an air outlet (2513) coaxial with the movable plug; a sealing film (2522) is arranged in the middle of the piston hole (2521), an arc-shaped groove (2523) is formed in the sealing film (2522), and the arc-shaped groove (2523) does not axially correspond to the air outlet hole (2513);

when the movable plug (2512) moves downwards to the lowest point, the air outlet (2513) is attached to the sealing film (2522) and is sealed; at the moment, the movable plug (2512) moves upwards, and vacuum-pumping negative pressure is generated in the piston hole (2521) because the air outlet hole (2513) is closed; when the movable plug (2512) moves upwards to the highest point, the closing film (2522) resets under the elastic acting force, and the air outlet hole (2513) is opened and communicated with the interior of the piston hole (2521) through the arc-shaped groove (2523); at the moment, the movable plug (2512) moves downwards, and the gas in the piston hole (2521) is discharged through the arc-shaped groove (2523) and the gas outlet hole (2513) in sequence; when the movable plug (2512) moves to the lowest point again, the movable plug is closed close to the closing film (2522), so that the movable plug (2512) of the rocker (251) reciprocates up and down in the piston hole (2521) of the silica gel piston (252) to realize the vacuum pumping effect of the vacuum pumping pump (25).

7. The vacuum extractor of claim 4, wherein: the suction head (254) comprises a suction head upper cover (2541) and a suction head lower cover (2542) which are spliced up and down.
