The invention relates to the technical field of optical load on-orbit application, and particularly provides an optical-mechanical structure of an on-orbit assembled space telescope, a primary mirror assembly comprises a central sub-mirror module and a side lobe sub-mirror module, the central sub-mirror module is connected to the front end face of a central module through a central sub-mirror truss, and the side lobe sub-mirror module is connected to the side lobe sub-mirror module; the side face of the central sub-mirror truss is connected with a side lobe sub-mirror truss, and the side lobe sub-mirror module is connected to the side lobe sub-mirror truss. The secondary mirror assembly is connected to one end of the secondary mirror truss, the other end of the secondary mirror truss is connected to the top surface of the central module, and the secondary mirror truss adopts a single-arm truss and is formed by splicing a plurality of sections of secondary mirror trusses; the resource bin is connected to the bottom face of the central module, and the light shield is connected to the resource bin and is unfolded or folded through the shear fork type telescopic arm. The on-orbit assembly space telescope with the aperture of 10 m magnitude can be met, and the on-orbit assembly space telescope is good in ground manufacturing feasibility, low in carrying and ascending cost, low in on-orbit assembly difficulty and high in on-orbit adjustment efficiency.
