And after the two connecting blocks of the second frame are respectively positioned with the two side surfaces of the first frame through the positioning pins, the connecting blocks are connected with the two side surfaces of the first frame through the connecting screws.
Furthermore, through holes are respectively processed on two opposite side surfaces of the first frame; and the through holes are internally provided with rotating shafts connected with the common-caliber optical lens respectively.
Furthermore, during installation, the common-caliber optical lens is installed in the first frame, and then the second frame is in butt joint with the first frame and is installed outside the common-caliber optical lens, so that split installation of the adjusting frame is realized.
Has the advantages that: (1) because the lower part of the common-caliber lens is provided with the semi-active laser optical system, the whole lens is larger in size, and therefore the pitching frame is designed into a split structure and is respectively the first frame and the second frame which are connected through the connecting screw, the common-caliber lens has the characteristics of compact structure and convenience in assembly, and the problem that the mounting space of the common-caliber lens is insufficient is effectively solved.
(2) The rotating shafts connected with the common-caliber optical lens and arranged in the through holes on the two side surfaces of the first frame can realize the pitching motion of the common-caliber optical lens; the rotation, namely the azimuth motion, of the common-caliber optical lens along the axis of the upper shaft can be realized through the upper shaft.
