Abstract: An adjustable electric adaptor includes a first connecting member, a second connecting member including an end pivotally connected to an inner end of the first connecting member, a first connector securely mounted in an outer end of the first connecting member, and a second connector including an electrically insulating housing. A tubular section extends from the electrically insulating housing and through a central hole of the second connecting member. The second connector is electrically connected to the first connector by a cable that extends through the tubular section. The second connector is pivotable about a central axis of the central hole of the second connecting member relative to the first connector. The first connector and the second connector are pivotable relative to each other about an axis orthogonal to the central axis of the central hole of the second connecting member.
