Hand-held electric sealer having a detachable electric sealing module

A hand-held electric sealer having a detachable sealing module, comprising:

• a casing, having a module chamber and a battery chamber separated from each other by a partition plate, where the module chamber is covered with a battery cover plate and the partition plate is attached with metal contacts;
• a sealing module, unitarily attached to or detached from the module chamber of the casing, including a module cover plate and a module seat plate which together form an accommodating space for receiving a heating mechanism, where the top portion of the heating mechanism protrudes from the module cover plate when the heating mechanism is biased by a spring secured in the module seat plate;
• and
• a press bar, pivotally fixed at the rear end of the casing, so that the front end of the press bar can pivotally depress the heating mechanism when the heating mechanism is biased to protrude from the module cover plate.
