Adapter with diversified plugs and rectifying function
 An adapter with diversified plugs and rectifying function. The adapter including a casing and a pivotally jointed cover. A penetration-disposing portion in a vacant lot of the casing is defined by a plurality of partition portions for setting differently sized plug pins. The adapter includes internally hollowed auxiliary pins or conductive members. In an outer rim of each of the partition portions, a first snap-retaining section is formed in association with an outer rim of the auxiliary pins or the plug pins. A circuit coupled with an external power cord and two conductive units connected to the circuit are built in the cover. One end of the conductive members can be depressed to contact an arbitrary set of the plug pins, and after the cover is closed, the conductive units are depressed to contact the conductive members to force the plug pins to be exposed through the penetration-disposing portions for coupling with an external power source.
