[0034] A novel hinged closed-loop high-reliability piezoelectric fast-reflecting mirror comprises a hinged closed-loop piezoelectric fast-reflecting mirror 101, a base 105 and a shell 201, wherein a plurality of screws Ⅰ102 are evenly arranged on the outer side of the hinged closed-loop piezoelectric fast-reflecting mirror 101 along the circumferential direction, a display board 202 is fixedly connected to the top of the shell 201, and a plurality of upwardly protruding connection seats 203 are evenly arranged on the display board 202 along the circumferential direction, a plurality of screws Ⅰ102 pass through the outer edge of the hinged closed-loop piezoelectric fast-reflecting mirror 101 and are installed on the corresponding connection seats 203, and the hinged closed-loop piezoelectric fast-reflecting mirror 101 is synchronously fixedly installed on the display board 20 2, the bottom of the housing 201 is fixedly connected to the base 105, the middle of the base 105 is fixedly connected with a support rod 104, the top of the support rod 104 extends into the hinged closed-loop piezoelectric fast-reflecting mirror 101, the top of the support rod 104 is installed with a screw rod II 103, the middle of the screw rod II 103 is sleeved with a disc spring 106, the lower side of the disc spring 106 is in contact with the inner side of the middle of the hinged closed-loop piezoelectric fast-reflecting mirror 101, the upper surface of the middle of the base 105 is evenly provided with four piezoelectric ceramic components 401 along the circumferential direction, and the four piezoelectric ceramic components 401 are evenly placed in the housing 201 along the circumferential direction.

[0035] This part is based on Figure 1-16The working process expressed in the figure is: in order to provide a new hinged closed-loop piezoelectric fast-reflecting mirror with high reliability, in the process of using the piezoelectric fast-reflecting mirror, when the light beam is irradiated to the upper surface of the hinged closed-loop piezoelectric fast-reflecting mirror 101, the two piezoelectric ceramic components 401 at any desired position, front and rear, or left and right sides, can be energized, and then the piezoelectric ceramic components 401 on both sides are pushed from the bottom surface of the hinged closed-loop piezoelectric fast-reflecting mirror 101 to make the surface of the hinged closed-loop piezoelectric fast-reflecting mirror 101 tilted, thereby adjusting the angle of refraction of the light beam, and the hinged closed-loop piezoelectric fast-reflecting mirror 101 is refracted. When the angle is adjusted, the disc spring 106 in the middle thereof which is sleeved on the middle part of the screw rod II 103 will be directional squeezed synchronously. Therefore, the elasticity of the disc spring 106 provides a restoring force for the hinged closed-loop piezoelectric quick response mirror 101 to return to its original position after the angle is adjusted.

A sliding ring 601 is slidingly fitted on the outer side of the fitting ring 501, and a limit rod 604 is fixedly connected to the left and right sides of the bottom of the sliding ring 601, respectively. The two limit rods 604 are slidably connected to the two sides of the fitting ring 501.

[0041] A plurality of injection tubes 602 are evenly fixed and connected on the sliding ring 601 along the circumferential direction. The plurality of injection tubes 602 are arranged one-to-one corresponding to the plurality of corresponding holes on the fitting ring 501. The bottoms of the plurality of injection tubes 602 are evenly fixed and connected to the upper side of the storage frame 603 along the circumferential direction.
