1. A piezoelectric power generator using wind power, comprising:
a central axis unit comprising a charger;
a piezoelectric film supporting frame engaged onto an outer circumference surface of the central axis unit; and
a piezoelectric film having a pre-set area and at least one side being engaged to at least one of one side part of the piezoelectric supporting frame and the central axis unit,
wherein electricity generated by the piezoelectric film is delivered to the charger of the central axis unit,
the piezoelectric film supporting frame has a shape corresponding to a shape of an edge of the piezoelectric film to surround the edge of the piezoelectric film,
the piezoelectric power generator comprises at least one pair of the piezoelectric film and the piezoelectric film supporting frame,
the at least one pair of the piezoelectric film and the piezoelectric film supporting frame is engaged to a certain area of the outer circumference surface of the central axis unit, and
when receiving wind, the central axis unit is rotated to enable one side part of the piezoelectric film supporting frame to face the wind.
