Embodiment Construction
[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0045] A piezoelectric linear actuator provided by the present invention has the characteristics of nanometer-level precision, long stroke, and large output force. The inchworm-type piezoelectric linear actuator with this novel structure can have large stroke, large It has the characteristics of output force and large output stiffness, and can effectively resist the performance degradation of the drive caused by wear and tear during long-term operation of the drive....
