Abstract

The utility model relates to a manual focusing mechanism for double optical paths, and belongs to the technical field of focusing of handheld equipment. Comprising a focusing frame, a first focusing mechanism and a second focusing mechanism. The focusing frame comprises a focusing fixing seat, a middle adapter plate and a focusing upper cover, the first focusing mechanism comprises a first focusing wheel, a first focusing lead screw, a first focusing nut, a focusing pull rod and a first connecting arm, and the second focusing mechanism comprises a second focusing wheel, a transmission shaft, a second focusing lead screw, a second focusing nut and a second connecting arm. The focusing mechanism can be independently assembled, then the focusing mechanism and the lens cone assembly are assembled, the focusing mechanism is convenient to disassemble, assemble and maintain, batch production can be carried out, the first focusing mechanism and the second focusing mechanism which are assembled achieve the independent manual focusing function of the double-optical-path lens, the relative position between the two lenses in the focusing process is stable, and the focusing effect is good. And the optical path of the other lens cone assembly is not interfered, so that the focusing clearness of each lens cone assembly is ensured, and the overall performance of the handheld equipment is improved.
