Then, the positioning springs 12 on both sides of the spiral metal wire 2 are inserted into the slots 20. The positioning springs 12 then quickly spring back, pushing the positioning block 13 to engage with the positioning slot 11, thereby positioning the spiral metal wire 2. During use, the spiral metal wire 2 is placed outside the wire sheath 1, which can prevent the wire sheath 1 from dragging on the ground and causing wear, thus effectively protecting the wire. In addition, a glass fiber layer 15 is provided inside the wire sheath 1 of this power cord. The glass fiber layer 15 has good heat insulation performance.
