Embodiment Construction
[0020] The present invention will be further described in detail below with reference to the drawings and specific embodiments.
[0021] Such as figure 1 , Figure 2a , Figure 2b with image 3 As shown, the present invention is a positive and negative bidirectional micro-displacement amplifying flexible mechanism based on shear-type piezoelectric ceramics, including a rhombus-shaped amplifying structure 1, located in the middle of the rhombic-shaped amplifying structure 1, and an upper displacement input terminal 1-3 formed integrally with it. The upper displacement output terminal 1-1 and the lower displacement output terminal 1-2 are respectively located at the upper and lower part of the diamond-shaped amplifying structure 1 and integrated with the diamond-shaped amplifying structure 1 with the lower displacement input terminals 1-4; symmetrically arranged in the diamond-shaped amplifying structure There are two shear piezoelectric ceramics 2 with exactly the same geometric di...
