Hand electirc welding tongs

The utility model relates to a pair of handwork electric welding tongs. The utility model is composed of a straight handle, a bending arm, an upper and a lower tong mouths, a fixing pin, a torsion spring, a bakelite cover, a high temperature resistance protective cover, cable fixing cavity and screw nails. The utility model is characterized in that the structure that the bending arm and the upper tong mouth are originally made into a whole by utilizing copper materials and the straight handle and the lower tong mouth are originally made into a whole by utilizing the copper materials is changed into a two-body structure, and the shape is not chaned. A bending arm which is made of ferrous materials is pressed on the upper tong mouth, and a straight handle which is made of ferrous materials is pressed on the lower tong mouth. The temperature resistance protective cover which is coated with heat insulation nanometer is pressed on the bending arm and the straight handle at the upper and lower tong mouth parts, and the three parts are fixed by the screw nails. The fixing pin adopts a pin which is coated with a nanometer heat insulation layer, the torsional spring is adopted and a center hole of the torsional spring is sheathed on the pin. One end of the torsion spring is supported in a groove in the inner side of the bending arm, and the other end is supported in a groove in the inner side of the straight handle.
