A through slot 7 is opened at a position near the bottom on one side of the vacuum pumping component 4, and the through slot 7 facilitates the user to place the bag mouth into the vacuum pumping component 4. A pressing plate 8 is arranged on the other side inside the vacuum pumping component 4, and the pressing plate 8 plays a role in pressing and limiting. A plurality of grooves 9 are opened at the bottom of the pressing plate 8, and the grooves 9 leave a moving space for the conduits 6.

[0022] Furthermore, the notch 2 and the main machine 1 are integrally designed. Among them, the notch 2 facilitates the user to place materials.
