The invention provides a single-degree-of-freedom conical axial and radial synchronous unfolding and folding mechanism, and particularly belongs to the technical field of aircrafts. Through the structural arrangement of connection between the main supporting rod and the auxiliary supporting rod, the overall conical mechanism can be unfolded through the axially-arranged fixing circular ring, and the overall conical mechanism is good in rigidity and simple in structure; through the structural arrangement of the two supporting assemblies, the overall conical mechanism has the structural characteristics of being single in degree of freedom, simple in structure and high in rigidity, and the unfolding and folding ratio of the overall cone is larger. The device comprises a main supporting rod and an auxiliary supporting rod, and further comprises a fixing circular ring, an upper-layer supporting assembly and a lower-layer supporting assembly. An auxiliary supporting rod is arranged above the main supporting rod, a fixing circular ring is arranged above the auxiliary supporting rod, an upper-layer supporting assembly is arranged between the main supporting rod and the auxiliary supporting rod, and a lower-layer supporting assembly is arranged below the main supporting rod. 24 third revolute pairs are installed on the fixed circular ring at equal angles, and one end of each third revolute pair is connected with an auxiliary supporting rod.
