Background technique

The power converter is what we usually call a power socket. At present, most of the known and commercially available power converter products have holes on one surface and are relatively close to each other. In this way, the number and position of the holes of each power converter are basically fixed. Since the plugs of the electrical appliances we use are mostly of different specifications, problems will often arise when using the products currently on the market. For example, a plug with a larger specification is inserted on the power converter, causing the positions of other holes to be insufficient or simply unusable, or, when we need to plug many plugs into one power converter, the power converter used often They all have a large volume and occupy a large area, so it is very inconvenient, and, as our lives continue to change, the needs of our lives are also constantly changing. When our demand for products will change, we must not However, it is difficult for the power converters currently on the market to meet our changing needs in life.
