Abstract
The invention relates to an adjustment mechanism based on a flat glass correction optical axis system. The mechanism comprises flat glass, a body, a swing arm, a cantilever, a support, a screw I, a screw II and a universal bearing. One end of the flat glass is cooperated with the universal bearing and is transversely installed on the body through a rotating shaft. The swing arm is fixed to a rotating shaft of the flat glass. The screw I and the screw II are vertically installed on the body through screw threads. When the screw I moves up and down, the swing arm is driven to rotate and the flat glass is driven to rotate along a same direction. The cantilever is fixedly connected to the other end of the flat glass. When the screw II moves up and down, the cantilever is driven to move up and down and the flat glass is driven to move vertically. The support is fixedly connected to the body. Adjustments along two directions of the adjustment mechanism are realized through adjusting the screw I and the screw II respectively. The universal bearing is used. Elevation and orientation adjustments of the optical axis do not influence each other and possess mutual independence.
