ABSTRACT:
A hand-held electric sealer used for sealing a plastic bag or the like, including a casing, a sealing mechanism, a press bar, and a safety device. The sealing mechanism has a heating wire, which produces heat for sealing the plastic bag or the like when turned on. The safety device controls the heating of the sealing mechanism, and stops the sealing mechanism from being triggered accidentally.
