illimitable socket Plugin

All day when we want to plug in our computer or other Electrical thing to the electricity we have problems with the angel of other plugin that put us in difficulty.
Another problem with the old socket is when we put them in the electricity and turn on the button we know there is electricity in it but we can not understand in all socket we have the electricity or not ?!!
In this model I design a mechanism that let the socket rotate and make an angle with the other socket and put an ELD around the each socket to show that the electricity is in this socket or not and another property of this model is that we can increase or decrees the number of socket as easy as drink a glass of water !
