the lower end of the second polygonal side wall of the bottom surface of the fixing frame can be in sealing sleeve fit with the upper end of the first polygonal side wall of the bottom surface of another fixing frame arranged below the bottom surface of the fixing frame to form an air supply pipeline communicated with the fixing frame units of the cage boxes.

11. The rotary IVC system of claim 1, further comprising a cage frame for receiving a cage mount, the cage frame comprising a bottom plate, a top plate and a plurality of frame liners disposed between the top plate and the bottom plate, the cage mount rotatably disposed within the cage frame, the bottom plate having a plurality of casters fixedly disposed on a lower end surface thereof.

12. The rotary IVC system of claim 11, wherein said top and bottom plates are formed with an air suction opening communicating with said exhaust duct, said top plate is formed with an air intake opening surrounding said air suction opening and communicating with said supply duct, said air suction opening and air intake opening communicating with a fresh air supply and exhaust system in a barrier environment via a cage frame fluid conduit having a quick connector, thereby forming a cage circulation fresh air supply and exhaust system.

13. The rotary IVC system of claim 12, wherein a sealing ring and a rotating shaft are disposed between the lower end surface of the top plate and the upper end surface of the cage holder at positions corresponding to the positions of the air supply line and the air inlet and the positions of the air exhaust line and the air exhaust port, and a rotating shaft is disposed on the bottom plate at a position corresponding to the position of the air exhaust line and the air exhaust port.

14. The rotary IVC system of claim 1, wherein the plurality of exhaust ducts have the same length and aperture and the plurality of supply ports have the same aperture.
