In detail, the first and fourth ring frames 11 and 14 may form a concentric structure, and the second and third ring frames 12 and 13 are symmetrically disposed at upper and lower sides of the concentric structure. The plurality of support rods 2 can be uniformly and alternately distributed among the circular ring frames 1, so that the overall structure of the net cage frame is more uniform and symmetrical, and the stress is more balanced.
