Abstract: A vacuum sealing device includes a sealing base and a sealing cover arranged on the sealing base, the sealing base is also provided with a push-pull assembly for pushing and pulling the sealing cover; the push-pull assembly includes two piston cylinders disposed at both ends of the sealing base, a piston assembly disposed within the piston cylinder and pivoted to said sealing cover, and a pneumatic assembly disposed in the sealing base and pushed the piston assembly to reciprocate within the piston cylinder. The vacuum sealing device solves the trouble that the original mechanical structure needs to close and open the seal cover manually, thus realizing automatically vacuum sealing functions, it releases hands and greatly increases the convenience of operation.
