The present invention relates to micro device assembling technology, and is especially a kind of stepped omnibearing nanometer moving platform for micro processing, biological cell operation, etc. The stepped omnibearing nanometer moving platform consists of upper platform and three piezoelectric drivers hinged elastically to the upper platform and arranged homogeneously in the periphery of the upper platform. Each of the piezoelectric drivers includes one driving unit, and two or more driving units are connected serially. Each driving unit consists of two piezoelectric ceramics, one cross beam and one contact element. Each of the piezoelectric ceramics is connected to the control circuit and is radio communicated with computer through communication circuit. The present invention can realize omnibearing planar nanometer motion in raised mechanism precision and flexibility.
