[0002] At present, single-row sockets on the market generally use a combination of two flat pins and eight-shaped flat pins, which takes up a lot of space. Although it has two types of sockets at the same time for convenience, in actual use, the two different types of plugs interfere with each other due to the small upper and lower gaps. They cannot be inserted at the same time. From a safety perspective, multiple holes greatly increase the risk of electric shock. With the improvement of living standards and the increase in household electrical appliances, the number of sockets is also increasing. Big data shows that more than 20,000 people are injured or killed by electric shock from sockets each year. This type of design is not only inflexible in use but also increases the risk of electric shock. In order to improve safety and convenience, a reversible compatible socket is designed.
