• a housing comprising a first housing and a second housing;
• a plug part comprising a flat insertion piece installed in said housing;
• a plurality of elastic conducting contact points formed on said plug part;
• and
• an adjusting mechanism for positioning the plug part out of the housing so that the plug part can be removably inserted into an external power outlet;
• wherein the second housing can retract into the first housing to extend the flat insertion piece out of the housing through an opening of the second housing;
• and
• wherein the adjusting mechanism comprises a spring for ejecting the second housing out of the first housing when the flat insertion piece is being removed from the external power outlet;
• the second housing comprises an upper housing portion which has a safety unit mount part, a lower housing portion which has a socket core structure, and a bottom portion;
