An adaptor with foldaway plug components comprising a shell (1) and a plug components (2); said shell (1) has a recess (11) at its front end and said plug components (2) is inserted into the recess (11) of said shell (1); there are axle holes (111) and at least three projected/pitted points (112) in a circular line with the axle hole (111) as the center of circle in certain radius in both sidewalls of the recess (11), in which at least one point is conductive; said plug components (2) comprises a plug main body (21) and a plug (22) and said plug main body (21) has rotation axles (211) in both of its sidewalls. In both sidewalls of said plug (21) there are pitted/projected points (212) corresponding to the projected/pitted points (112), and at least one of such points is in integration with or in contact with said plug (22). Compared with the existing technology, the current invention has the following advantages: accurate positioning; good contact for conductive points; wide range of applications; wear resistance; long service life and easy manufacturing.
