Through this thread setting, after the first, second and third gears are driven to rotate by controlling the adjusting gear 17, the first, second and third sleeves move in the same direction along the axial direction of the first, second and third support shafts under the action of the first, second and third threaded portions, and finally drive the first, second and third rubber rollers to move in a unified direction along their axial directions.

[0018] Furthermore, the upper traction belt 1 also passes around the first tensioning roller 3, and a first slider portion 5 is extended at one end of the first tensioning roller 3, and the first slider portion 5 is slidably set in the first slide groove on the first mounting bracket 6, and a first adjusting screw 4 is rotatably set on the first mounting bracket 6, and the first adjusting screw 4 is screwed with the first slider portion 5. By controlling the rotation of the first adjusting screw 4, the first tensioning roller 3 is driven to move radially, and then the upper traction belt 1 is tensioned, and the lower traction belt 2 also passes around the second tensioning roller 12, and a second slider portion 14 is extended at one end of the second tensioning roller 12, and the second slider portion 14 is slidably set in the second slide groove on the second mounting bracket 8, and a second adjusting screw 13 is rotatably set on the second mounting bracket 8, and the second adjusting screw 13 is screwed with the second slider portion 14.
