Support deformation structure of piezoelectric plates/strain gauges and piezoelectric power generation device

The invention discloses a support deformation structure of piezoelectric plates/strain gauges and a piezoelectric power generation device. The support deformation structure comprises a support deformation assembly comprising a bottom plate, wherein the bottom plate is provided with at least one support deformation member; the support deformation members comprise two oppositely disposed clamping members, both of which can clamp the piezoelectric plates/strain gauges; a lever member is disposed between the two clamping members, the pressing end of the lever member presses against the top of thepiezoelectric plate/strain gauge of a clamping member, and the support end of the lever member is supported at the bottom of the piezoelectric plate/strain gauge sandwiched by the other clamping member. The structure not only can well fix the piezoelectric plates/strain gauges, but also is easier for the assembly and disassembly of the piezoelectric plates/strain, and the lever member can generatea larger deformation vari
