The present invention relates to a plug which is connected to a power outlet and supplies power to an electric device. Particularly, the connection of the 110V power supply and the 220V power supply is carried out by storing the straight connection member and the circular connection member therein and selecting them as necessary to allow them to be discharged forward. The present invention relates to a 110 / 220V combined plug which can select connecting members which integrate the means to reduce the size and simplify the size while eliminating the trouble of use due to the detachable detachment.

In general, an electric device or an electric product is provided with a plug connected to a power outlet to supply power to an end of the power supply. The plug is usually shaped differently for 110V or 220V for power supplies used in homes. Generally, the 110V power supply has a straight connection member, and the 220V power supply has a circular connection member. Thus, in order to use electrical devices or electrical appliances that are standardized by supplying 110V or 220V power according to the assumption at these positive voltages, an adapter is attached to one power plug to be used for another power supply. An example of this is shown in FIG. 1.
