Improved power line

The utility model relates to the technical field of power lines, and discloses an improved power line which comprises a power line body, an automatic winding mechanism is arranged in the middle of the power line body, and limiting fixing mechanisms are arranged at the two ends of the automatic winding mechanism. According to the improved power line, the automatic winding mechanism is arranged, the power line body is pulled to drive the winding wheel to rotate on the inner wall of the storage box to release the power line body, the purpose of stretching is achieved, and similarly, when the power line body needs to be stored, only the power line body needs to be released, and the power line body can be conveniently stored. The winding wheel is stressed to rotate and reset through the counter-acting force of the torsional spring, the power line body is rotationally wound in the middle of the winding wheel, winding and storage of the power line body are achieved, and therefore the purposes that the power line bod
