description of the drawings:

FIG. 1 is a schematic view of the cross-sectional structure of the present invention;

in the figure, 1, cupping jar body; 2. a tank opening; 3. a one-way valve; 4. a hollow cylinder; 5. a piston; 6. a one-way valve; 7. A connecting rod; 8. a push-pull device; 9. a housing; 10. a trench; 11. a slideway; 12. the gas outside the tank body enters a switching device in the tank body;

the specific implementation mode is as follows:

in order to clearly illustrate the technical features of the present solution, the present invention will be explained in detail below by means of a representative embodiment and with reference to the accompanying drawings;

1. see figure 1;

2. the cupping jar opening 2 is tightly attached to the skin, the push-pull device 8 is pulled along the direction opposite to the jar opening 2, the push-pull device moves along the groove 10 of the shell through the slide way 11, the connecting rod 7 connected with the push-pull device 8 drives the piston 5 to move along the direction opposite to the jar opening 2 in the hollow cylinder 4, because the piston 5 is in sealing contact with the inner wall of the cylinder 4, the gas in the jar body 1 is discharged into the cylinder 4 through the one-way valve 3, negative pressure is generated in the jar body 1, the one-way valve 6 is in a closed state at the moment, the gas in the cylinder 4 cannot be discharged, then, the push-pull device 8 is pushed along the jar opening direction, the push-pull device 8 moves along the groove 10 of the shell through the slide way 11, the connecting rod 7 drives the piston 5 to move towards the jar opening direction in the cylinder 4, the gas in the cylinder 4 is discharged through the one-way valve 6, repeating the above actions, the negative pressure in the cup body is continuously increased until the negative pressure reaches the bearing degree of the cupping people, and the cup body 1 is adsorbed on the skin at the moment;
