Each sliding guide block 17 is provided with a limiting groove, which extends along the length direction of the first side plate 104 and the second side plate 105. The two sides of the mounting member 2 are respectively slidably disposed in the two limiting grooves, which can reduce the friction of the mounting member 2 sliding and prevent the mounting member 2 from shifting.

[0039] Optionally, the chain drive belt tensioning device also includes a rotating shaft 7, which is fixed to the mounting component 2. The smooth tension wheel 3 is rotatably mounted on the rotating shaft 7, which can ensure that the smooth tension wheel 3 rotates smoothly.

[0043] Optionally, the chain drive belt tensioning device further includes a first fastener 10 and a second fastener 11. An adjusting rod 4 passes through a third connecting plate 23. The first fastener 10 and the second fastener 11 are respectively disposed on both sides of the third connecting plate 23, and both are threadedly connected to the adjusting rod 4 so that the first fastener 10 and the second fastener 11 can clamp the third connecting plate 23. Specifically, both the first fastener 10 and the second fastener 11 are nuts. In this embodiment, the second fastener 11 is a double-nut locking type.
