Problems solved by technology
[0002] At present, many household appliances such as refrigerators, TVs, computers, microwave ovens, washing machines, electric shavers, mobile phone chargers, etc. have power cord plugs connected to the power supply. The power cords provided by the manufacturers are usually relatively long, and the extra cords can only be wrapped up and placed on the ground, which will affect the tidyness of the room; if it is the power cords that need to be carried when going out, such as mobile phones and razors, it is also extremely inconvenient to carry
