Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as figure 1 , figure 2 and image 3 As shown, the present invention is based on the U-shaped stepping piezoelectric actuator of the double clamping plate power-off locking mechanism, including a housing 1, a double clamping plate 2 fixed to the housing 1 at both ends, and a double clamping plate passing through the double clamping plate. 2. U-shaped rod 11 with internal clamping hole; double clamping plate 2 is composed of upper clamping plate 3 and lower clamping plate 4 which are inverted and both ends are fixedly connected to shell 1, wherein upper clamping plate 3 and lower clamping plate The clamping plates 4 have the same structure, and are equipped with concave arcs 5, concave circular grooves 6, clamping piezoelectric stack installation places 8 and flexible hinges 7, and the upper clamping piezoelectric stack 9...
