[0022] The following is a detailed description of the specific settings and functions of this embodiment. Through the setting of the tensioning sprocket 7, sprocket tensioning is adopted, and the chain is tensioned by several small sprockets. It is simple and convenient and the damage to the chain is minimized. It eliminates the original multi-stage drive of small sprocket with large sprocket and small chain with large chain, and eliminates the need for a separate tensioning device, so that the drive and tension are closely combined, optimizing the overall circulation system, making it more convenient to use and not easy to be damaged.

[0023] Example 2: Figure 1 - Figure 4 As shown, the lower end of the supporting plate 2 is fixedly connected to the connecting disk 13, and a supporting plate 3 is provided below the supporting plate 2. The upper end of the supporting plate 3 is fixedly connected to the sleeve plate 12, and the sleeve plate 12 is sleeved with the connecting disk 13.
