A handy electric heat sealing apparatus including a casing (10), a heat sealing unit (40) and a press handle (20), wherein a safety switch (80) is mounted in the casing and shifted to stop contacts (43) of the heat sealing unit from contacting the contacts (31) of a power supply circuit in the casing. The heat sealing unit includes a heat insulative base (41) having a projecting block (411) and an electric heating wire (42) fastened to the projecting block and connected to two opposite metal contact plates (43) of the heat sealing unit. A cover shell (44) covers the casing over the heat insulative base (41) and has a centre opening through which the projecting block of the heat insulative base projects out of the cover shell. A heat insulative sheet (45) covers the electric heating wire (42) and a cover frame (46) fastened to the cover shell (44) holds the heat insulative sheet in place. The casing has a rear chamber (111) in which is an electric socket (112) for receiving an electric plug. A stop rod (114) in the rear chamber is adapted for holding the electric wire of the electric plug in place. <IMAGE> <IMAGE> |
