Abstract: An extractable conversion plug with a safety protection means includes a spring is located between a moveable pillar of a slab and a latching element, inside a connection head, such that the slab can cover conduction pieces through an elastic force from an expansion of the spring, thereby preventing the conduction pieces from being exposed. Upon emplacing the connection head at a base seat, the slab is stopped from moving by a stopper, and the conduction pieces are exposed and are contacted with spring leaves of the base seat, thereby constituting a close-circuit status. When the base seat falls off by accident, a stopping force of the slab is relieved to release a compression force from the spring, which will cause the spring to expand, so as to move the slab to cover the conduction pieces, thereby preventing from getting an electric shock by a careless touch.
