9. The method for assembling a truss support structure for a space camera according to claim 8, wherein: The truss (6) is connected to the upper joint (5) and the lower joint (7) by gluing.

10. The method for assembling a truss support structure for a space camera according to claim 8, wherein: After curing in step 6, the positioning pins and connecting screws between the front frame (4) and the tooling upper plate (3), the rear frame (8) and the tooling lower plate (1), and the tooling upper plate (3) and the tooling column (2) are removed in sequence. After removing the tooling upper plate (3), the space camera truss support structure is taken out from the assembly tool to complete the assembly.
