Claim:
A power outlet, comprising: a casing; a middle-layer support inside the casing, the middle-layer support comprising at least one guiding jack; at least one conductive plug bush below the middle-layer support; and at least one safety shield device comprising: a spring having a first end and a second end; a left shield and a right shield, each comprising: a hollow frame comprising first and second opposed planar sides, a front end perpendicular to the first and second opposed planar sides, and a planar rear end perpendicular to the first and second opposed planar sides; a stop block at the front end of the hollow frame with a guiding slope on an outer surface and a spring mounting position on an inner surface; a planar lock-up step at an inner edge of the hollow frame, the lock-up step closer to the rear end than to the front end, and the lock-up step perpendicular to the planar rear end and perpendicular to the first and second opposed planar sides; and a shield foot extended from the planar rear end of the hollow frame towards the middle-layer support, wherein: the at least one guiding jack is vertically aligned with the at least one conductive plug bush to receive a pin of a power plug, the left shield and the right shield are stacked together and slide relative to each other, the first end of the spring rests against the spring mounting position on the stop block of the left shield and the second end of the spring rests against the spring mounting position on the stop block of the right shield, and the middle-layer support further comprises a sliding platform configured for the left shield and the right shield to slide on, the sliding platform having a left location hole for insertion of the shield foot of the left shield and the sliding platform having a right location hole for insertion of the shield foot of the right shield.
