Novel it is steady for instance platform that piezoelectricity sharply actuates two dimension

The utility model provides a novel it is steady for instance platform that piezoelectricity sharply actuates two dimension should actuate the platform and can be two -way initiative displacement output respectively at X and Y direction to make up into actuating of in plane optional position. X and Y direction are connected in parallel by two the same piezoelectricity straight line actuator respectively and form, and this piezoelectricity straight line actuator is established ties by the enlarged displacement mechanism of amplification that declines of the triangle of two differences to constitute, and the triangle mechanism of amplification designs respectively and actuates the unit for regular triangle is enlarged and fall the enlarged unit that actuates of triangle to can realize the two -way requirement that actuates in X and Y direction. The utility model discloses a to connecting in parallel of regular triangle mechanism of amplification and the mechanism of amplification of falling triangle series unit, can realize an ascending two -way initiative displacement output target in side to satisfy steady optional position like the platform lens and actuate, also can export simultaneously and satisfy the required power of platform movement.
