The invention discloses a novel satellite-borne large-scale deployable cable net antenna peripheral truss device which comprises an annular peripheral truss formed by splicing a plurality of planar linkage mechanisms and a driving device for driving the annular peripheral truss to be unfolded or folded. The plane connecting rod mechanism comprises a center shaft, a first sliding block base and a second sliding block base, the first sliding block base and the second sliding block base vertically slide on the center shaft, and sliding hinge connectors are distributed in the circumferential direction of the first sliding block base and the circumferential direction of the second sliding block base. The sliding hinged connectors on the first sliding block bases are sequentially connected with connecting bases through a plurality of first connecting rods respectively, supporting rods are arranged between the corresponding connecting bases, and every two adjacent plane connecting rod mechanisms share the connecting bases and the supporting rods. The device is adjustable in scale, can be repeatedly used, and has a great folding-unfolding ratio and high structural strength.
