The micro mirror box for scanning probe microscope includes an electrostrictive stepped unit, an electrostrictive scanning tube, a box, a box cover, a sample seat, a probe, a probe rack, a communication interface and a pumping hole, as well as a sample cutting push rod and an auxiliary probe. The probe and the auxiliary probe may be available probe for scanning tunnel microscope, atomic force microscope and/or magnetic microscope. The present invention has the features of simple and reasonable structure, low cost, small size, etc. and is favorable to raising vacuum degree, lowering temperature, raising S/N ratio, raising signal stability, etc. It may be used for vacuum cutting, vacuum probe replacement and scanning with different kinds of probe, in scanning tunnel microscope, atomic force microscope, magnetic microscope and their combination.
