Patent ID: 8919972

Claim:
An optical element adjustment mechanism applicable to load a reflection optical device, the optical element regulation mechanism comprising: a base movably assembled to the reflection optical device, the base being a hollow tubular structure, and each side of the base respectively having an opening, a plurality of loading surfaces disposed on an inner edge of one of the openings and stretching into a center of the base, and two leaning surfaces protruding along a tube wall of the base, the two leaning surfaces being plane and perpendicular to the plurality of loading surfaces; and a loading element movably assembled to the base and having a first surface, a second surface and two datum planes, the first surface flattened against the plurality of loading surfaces, the second surface disposed with a connection portion, the connection portion connected to an optical element, the two datum planes disposed to a side wall of the loading element and being perpendicular to the first surface, the two datum planes flattened against the two leaning surfaces; wherein at least one adjustment gasket is movably assembled between the base and the loading element to perform precision adjustment; wherein the two leaning surfaces are perpendicular to each other, and the two loading surfaces are respectively parallel to the two datum surfaces.
