[0014] 1. In the utility model, the limiting plug rod at the bottom of the No. 1 positioning plate is plugged into the limiting hole on the surface of the No. 2 positioning plate to locate the installation position of the No. 1 positioning plate and the No. 2 positioning plate, and then the fixing bolts are used to plug the No. 1 positioning plate and the No. 2 positioning plate, and then the fixing nuts are threadedly connected with the fixing bolts, so that the No. 1 positioning plate and the No. 2 positioning plate are fixedly installed, thereby fixing the circular top plate, the No. 1 connecting rod, the No. 2 connecting rod and the No. 3 positioning plate, and while the length of the cage main body mechanism is increased by the No. 1 connecting rod and the No. 2 connecting rod, the length of the longitudinal ribs is reduced, so that the deformation of the cage main body mechanism can be reduced, the stability of the cage main body mechanism is improved, and the dust filter bag is convenient to install with the cage main body mechanism.

[0024] Specifically, the limiting plug rod 19 at the bottom of the No. 1 positioning plate 13 is plugged into the limiting hole 110 on the surface of the No. 2 positioning plate 14 to locate the installation position of the No. 1 positioning plate 13 and the No. 2 positioning plate 14, and then the fixing bolt 15 is plugged into the No. 1 positioning plate 13 and the No. 2 positioning plate 14, and then the fixing nut 16 is threadedly connected to the fixing bolt 15, so as to facilitate the fixed installation of the No. 1 positioning plate 13 and the No. 2 positioning plate 14, thereby fixing the annular top plate 11, the No. 1 connecting rod 12, the No. 2 connecting rod 17 and the No. 3 positioning plate 18. While the length of the cage main body mechanism 1 is increased by the No. 1 connecting rod 12 and the No. 2 connecting rod 17, the length of the longitudinal ribs is reduced, the deformation of the cage main body mechanism 1 can be reduced, the stability of the cage main body mechanism 1 is improved, and the dust filter bag is convenient for installation with the cage main body mechanism 1.

[0025] As an optimization solution, Figure 1 , Figure 2 and Figure 4 As shown, the surfaces of the No. 1 connecting rod 12 and the No. 2 connecting rod 17 are fixedly connected with a reinforcement mechanism 2, and the reinforcement mechanism 2 includes a fixed block 21, and a connecting inner tube 26 is fixedly connected to one side of the fixed block 21, and a connecting outer tube 24 is inserted at one end of the connecting inner tube 26, and a connecting block 23 is fixedly connected to one end of the connecting outer tube 24, and a reinforcement rod 22 is fixedly connected to the surface of the fixed block 21, and a limiting groove 25 is arranged inside the connecting outer tube 24, and a limiting plate 27 is fixedly connected to the surface of the connecting inner tube 26, and the limiting plate 27 is located inside the limiting groove 25 and is slidably inserted into the connecting outer tube 24, and a spring 28 is fixedly connected to the inside of the connecting outer tube 24, and one end of the spring 28 is fixedly connected to the connecting inner tube 26.

[0026] Specifically, the reinforcing mechanism 2 is used to reinforce and support the No. 1 connecting rod 12 and the No. 2 connecting rod 17, so as to further reduce the deformation of the No. 1 connecting rod 12 and the No. 2 connecting rod 17. When the cage main body mechanism 1 is bumpy during transportation, when a No. 1 connecting rod 12 or a No. 2 connecting rod 17 in the cage main body mechanism 1 is bent and deformed, the No. 1 connecting rod 12 and the No. 2 connecting rod 17 will push the connecting inner tube 26 to slide along the connecting outer tube 24. At this time, the spring 28 will produce compression deformation, so as to buffer and support the deformed No. 1 connecting rod 12 and the No. 2 connecting rod 17, and protect the No. 1 connecting rod 12 and the No. 2 connecting rod 17.

[0027] Working principle: The limiting plug rod 19 at the bottom of the No. 1 positioning plate 13 is plugged into the limiting hole 110 on the surface of the No. 2 positioning plate 14 to locate the installation position of the No. 1 positioning plate 13 and the No. 2 positioning plate 14, and then the fixing bolt 15 is plugged into the No. 1 positioning plate 13 and the No. 2 positioning plate 14, and then the fixing nut 16 is threadedly connected with the fixing bolt 15, so as to facilitate the fixing and installation of the No. 1 positioning plate 13 and the No. 2 positioning plate 14, thereby fixing and installing the annular top plate 11, the No. 1 connecting rod 12, the No. 2 connecting rod 17 and the No. 3 positioning plate 18. The length of the cage main body mechanism 1 is increased by the No. 1 connecting rod 12 and the No. 2 connecting rod 17, while reducing the length of the longitudinal ribs, so as to reduce the deformation of the cage main body mechanism 1;

[0028] At the same time, the reinforcing mechanism 2 is used to reinforce and support the No. 1 connecting rod 12 and the No. 2 connecting rod 17, so as to further reduce the deformation of the No. 1 connecting rod 12 and the No. 2 connecting rod 17. When the cage main body mechanism 1 is bumpy during transportation, when a No. 1 connecting rod 12 or a No. 2 connecting rod 17 in the cage main body mechanism 1 is bent and deformed, the No. 1 connecting rod 12 and the No. 2 connecting rod 17 will push the connecting inner tube 26 to slide along the connecting outer tube 24. At this time, the spring 28 generates compression deformation, so as to buffer and support the deformed No. 1 connecting rod 12 and the No. 2 connecting rod 17, and protect the No. 1 connecting rod 12 and the No. 2 connecting rod 17.
