The invention discloses a resonance type bidirectional moving micro machine with a bistable rigid structure. The resonance type bidirectional moving micro machine comprises a shell, a top cover, an integrated multi-leg structure and a bistable trigger rod, wherein the top cover is in interference sliding groove fit with the shell; the integrated multi-leg structure is assembled in a groove in the bottom of the shell and penetrates out of the bottom of the shell; the coil is wound on the bistable trigger rod; according to the bistable-state piezoelectric resonance single-crystal-wafer-type piezoelectric resonance trigger mechanism, a bistable-state structure is used, structural resonance is converted into bidirectional movement, and meanwhile the bistable-state piezoelectric resonance single-crystal-wafer-type piezoelectric resonance trigger mechanism has the advantages of being easy to drive, compact in structure, small in size and easy to assemble.
