Angle socket / socket

A variety of socket-hole arrangements have created inconveniency for users when they plug their cable directly into a socket. That is, users have to bend their knees to identify socket-hole arrangement. Many designs to identify socket-hole had appeared, but you can not see with your own eyes in a standing position.
To remove this inconveniency, I propose a new design of socket, Angle Socket, that helps users easily identify its socket-hole arrangement. Also it helps users’ easy plug-in movement.
Eliminating users’ knee-bending movement to identify socket-hole arrangement.
