The insulating case has two side arms and a pivoting portion. The first and second inserted members are oppositely joined in the insulating case, and electrically connected. The plug is movably assembled to the insulating case. The plug has a third inserted member which is mated to the second inserted member. The plug has a sliding groove on its side, and the sliding groove corresponds to the first pivoting portion. Making use of this structure, the insulating case, the first inserted member, and the second member form an adjustable power plug adapter. When one adjustable power plug adapter is not used, it can slide and rotate away. The adjustable power plug adapters can be assembled together to correspond to a variety types of receptacles. ## Claims ### Claim 1 An adjustable power plug adapter structure, comprising: an insulating case having two side arms with a first pivoting portion;
