Socket capable of displaying voltage

The invention provides a socket capable of displaying a voltage. A voltage plate is arranged in the socket, the voltage can be displayed by a display screen on the socket, thus, whether an electrical appliance is used now can be decided according to the size of the voltage when the electrical appliance is used by people, and the influence of excessive low or high voltage on the electrical appliance is prevented. 本发明提供种可显示电压的插座，所述的插座内置有电压板，可以通过插座上的显示屏显示出电压，这样我们使用电器时，就可以根据电压大小来决定是否现在使用，避免电压过低或过高对电器造成的影响。
