Description of the Invention: [Technical Field] The present invention relates to a sealing machine, and more particularly to a double-head sealing machine having functions at both ends of the body. 5 [Prior Art] At present, there are a variety of light-capable small-sealing electric heat sealing machines on the market, which generally have a base, an electric heating module, and a pressing portion, and the electric heating module is installed at one end of the base. The other end of the seat is pivotally connected to the pressing portion, and the free end of the pressing portion is pivotable to the electric heating module. An electric heating line system is disposed in the electric heating module. When the pressing portion presses the electric heating module to cause displacement, the electric heating line and the electric power supply circuit are changed from open circuit to conduction. As the circuit is energized, the temperature rises to provide a thermal temperature for sealing the plastic bag mouth. ^Electrical, mode, and electric heating lines are usually single-wire electric heating handle sets of a single heating wire. Therefore, when the item previously packaged by the sealing machine is re-used for 15 times, the sealing part needs to be cut with scissors, and then packaged after use; the scissors and the sealing machine are often dispersed, and the same is used. It is extremely inconvenient. SUMMARY OF THE INVENTION The double-headed σ嫱4 & T mouth machine of the present invention comprises a base, an electric heating module, a press-fit cover, and a plenum.

Therefore, the same plastic bag can be reused for environmental protection purposes. The blade may be a ceramic safety blade, which may be an equivalent material of ceramic material, steel sheet. Where the expansion module is another electric heating module, another heat-resistant insulator may be disposed at the upper support base body, thereby forming a double-sealing electric heat sealing machine, that is, the electric heating modules at both ends of the sealing machine have different sealing lengths. . In addition, the design of the connecting member with respect to at least one of the upper support base and the lower support base is also easier to manufacture, the error rate is lowered, and the yield of the finished product is improved. Preferably, the upper support base, the connecting member, the 20 201002580 and the lower support base are independent components. Alternatively, the press-fit cover and the upper support body may be integrally formed or separated.
