The invention relates to the technical field of space deployable mechanisms, and discloses a space coiling type extension arm capable of realizing two-dimensional unfolding, which comprises a main arm mechanism, a secondary unfolding mechanism and a side arm mechanism, the main arm mechanism comprises a base assembly arranged at the bottom, longitudinal rods are arranged on the base assembly, and a transverse rod is arranged between every two adjacent longitudinal rods; the second-stage unfolding mechanism comprises a top plate connected with the upper end of the longitudinal rod, and a transmission assembly is arranged on the top plate; the side arm mechanism comprises fixed mounting plates arranged at the two ends of the top plate, side arm bases are arranged on the fixed mounting plates, side arm truss structures are arranged on the sides, away from the top plate, of the side arm bases, and side arm top plates are arranged at the ends of the side arm truss structures. According to the space coiling type stretching arm capable of achieving two-dimensional unfolding, by designing the two-stage unfolding mechanism composed of the gear system, cooperative unfolding of the second-stage two-coiling type stretching arm is achieved, and the main arm top plate has a limiting effect on unfolding of the side arm mechanism.
