New description: [New technical field] This is a load-bearing structure of a piezoelectric actuator, especially the arrangement of the corresponding elastic unit, so that the piezoelectric actuator does abut against the conveying device. In turn, the conveyor slipper is driven. [Prior Art] With the rapid development of science and technology, the industry is actively developing light weight, thin and short, low noise, high driving force, good heat dissipation, precision positioning energy, and can be widely used in 3C products. Thin drive units, such as thin motors or thin cooling fans. Recently, so-called piezoelectric actuators have been developed which have advantages such as low voltage, no noise interference, small volume, fast response, low heat generation, good precision, high conversion efficiency, and easy control. The conventional piezoelectric actuator works by using the input of electric energy to utilize the inverse piezoelectric effect to cause the piezoelectric material of the piezoelectric actuator (for example, piezoelectric ceramic) to generate the force of pushing and pulling due to the oscillation expansion and contraction, thereby driving The metal disk of the piezoelectric actuator vibrates to generate energy waves that are transmitted radially and outwardly, and the fixed member on the piezoelectric actuator forms a reflection point during the transmission of the energy wave. The reflection point formed by the metal disc at the position of the fixing member reflects the energy wave transmitted outwards back to the center of the circle, and thus causes the metal disk to generate driving force in a clockwise or counterclockwise direction due to deformation, thereby utilizing the metal The disc abuts the conveyor and drives the conveyor to slide forward or backward. As described above, the metal disk of the piezoelectric actuator is used to abut the conveying device and drive the conveying device to slide forward or backward, however, in long-term use.
