[0002] Plastic packaging bags are made of plastic and are used to produce a variety of daily necessities. They are widely used in daily life and industrial production. The development of plastic packaging bags began in the early 20th century. With the advancement of petrochemical technology, plastic materials were gradually developed and applied to the packaging industry. Self-sealing bags are plastic packaging bags that are pressed together to seal automatically. Common examples include dense bags, keel bags, and zipper bags. These resealable plastic packaging bags are made from polyethylene (LDPE) and high-pressure linear polyethylene (LLDPE) through blown film molding and hot-cutting. Common materials include PE, PO, EVA, and multi-layer composite zipper bags. Some packages can only be sealed with a keel or zipper. If the food inside the package needs to be sealed to reduce contact with air, a separate vacuum pump or pump is required, which is cumbersome and time-consuming. Utility Model Content

The interior of the gas cylinder 15 is provided with a piston 12 that slides inside the gas cylinder 15. One end of the piston 12 is connected to an A-adjustment shaft 14 with a folding function. The other end of the A-adjustment shaft 14 is connected to the pull rod 11. When the pull rod 11 is pulled to move, the piston 12 follows the movement of the pull rod 11 and simultaneously evacuates air from the interior of the packaging bag 21 through the straw 13. When the pull rod 11 is pulled to move, the slider 22 also follows the movement of the pull rod 11 to seal the packaging bag 21. When the slider 22 slides to the end of the packaging bag 21, the piston 12 simultaneously slides to the end of the gas cylinder 15. At this time, the symmetrical magnetic blocks on the pull rod 11 are magnetically connected;

[0021] When sealing the packaging bag 21, the pull rod 11 is pulled to move, so that the pull rod 11 moves and the B adjustment shaft 16 is driven to move. Since one end of the B adjustment shaft 16 is fixedly connected to the connecting rod 17, and one end of the connecting rod 17 is connected to one side of the slider 22, the pull rod 11 moves and the slider 22 moves on the slide of the packaging bag 21.
