Connecting structure and net cage structure

The utility model discloses a connecting structure and a net cage structure, and the connecting structure is characterized in that a fixed seat is provided with a connecting part used for being fixedly connected with a frame; the first side face of the fixing base is provided with an inwards-concave spherical surface, the inwards-concave spherical surface is provided with a first opening, and the first opening communicates with the second side face of the fixing base. The second side faces the first side. The movable rod penetrates through the first opening; a convex spherical surface concentric with the concave spherical surface is arranged at one end of the movable rod, and the convex spherical surface is in sliding fit with the concave spherical surface; a connecting ring is arranged at the other end of the movable rod and used for being connected with a rope sleeve of a net rope in a buckled mode. According to the technical scheme, relative sliding is generated between the outer convex spherical surface o
