One end of the reinforcement ring 18 located on the right side is fixedly connected to a symmetrically distributed pointed plug plate 21, and one end of the reinforcement ring 18 located on the left side is provided with a slot 22 corresponding to the pointed plug plate 21, and an array of springs 23 are fixedly installed inside the slot 22, and a connecting plate 24 is fixedly connected to the opposite end of the spring 23.
[0023] By adopting the above technical solution, the reinforcing ring 18 is initially connected to the connecting shaft 11 by setting the plug block 20 to be inserted into the slot 19, and then the reinforcing ring 18 is fixed to the outside of the first main shaft 1, the second main shaft 2, and the third main shaft 3 by utilizing the pointed plug plate 21, the spring 23, and the connecting plate 24, thereby realizing convenient assembly of the reinforcing ring 18, thereby better resisting sudden load capacity, and the structure is ingenious.
