A supply hub safety shield device for a power socket comprises left and fight slide blocks comprising sloped shields and platform shields. A slide platform is configured to house the left and right slide blocks such that the left and right slide blocks slide along a surface of the slide platform. The slide platform comprises first and second perforations configured to receive a hot blade and a neutral blade of an attaching plug. First and second elastic components push against the left and right slide blocks. Position blocks in a middle position of the slide platform, are configured to receive surfaces of the elastic components and are further configured to limit sliding distances of the left and fight slide blocks. First and second perforations are under the sloped shields when the sloped shields are in initial positions.
