Then the operator pushes the mounting column 9 to move. When the sealing gasket 11 contacts the extraction cup 7, the operator releases the handwheel 17, so that the first gear 16 and the driving rod 18 are reset under the action of the torsion spring 20, so that the positioning block 15 extends into the positioning groove 13. At the same time, the mounting column 9 is installed and fixed through the cooperation of the positioning block 15 and the positioning groove 13, so that the extraction cup 7 can be sealed through the contact between the sealing gasket 11 and the extraction cup 7, and at the same time the extraction cup 7 is fixed through the cooperation between the sealing gasket 11 and the support groove 6, so as to prevent the extraction cup 7 from tilting. Then, the operator controls the first motor 23 to work.
