Charger with take-up function

Abstract

The invention discloses a charger with a take-up function. The charger includes a charger body, a plug, a brake button, a scroll winder, a groove, a power line, a USB connector and a rotating shaft. The plug is arranged on one side of the charger body, the brake button is arranged on the surface of the charger body, the scroll winder is arranged inside the charger body, a groove is formed in one side of the scroll winder, the scroll winder and the USB connector are connected through the power line, and the rotating shaft is arranged inside the scroll winder. According to the charger, the scroll winder is arranged in the plug and a volute spiral spring is utilized as power. When the power line is pulled out, the volute spiral spring is tightened to store energy; when an external force is withdrawn, the spring releases energy, the rotating shaft automatically winds the power line; and through the setting of the groove, when the power line is wound, the USB connector can be retracted to the inside of the groove to prevent the connector from being exposed outside and damaged. The charger is reasonable in design, simple in structure, safe, reliable and convenient to use.
