The invention discloses a tensioning mechanism. The tensioning mechanism comprises a mounting seat, a tensioning wheel and elastic pieces; one end of the mounting seat is connected to a fixing plate of an air blower through a first connecting shaft; the tensioning wheel is connected to the other end of the mounting seat through a second connecting shaft and is located on the side, away from the fixing plate, of the mounting seat; the elastic pieces are contained between the mounting seat and the fixing plate and are arranged around the first connecting shaft, the end parts of the elastic pieces abut against the mounting base and the fixing plate; the elastic force generated by the elastic pieces enables the mounting seat to rotate around the first connecting shaft, and when the tensioningwheel abuts against a belt, the belt is enabled to be in a tensioned state, the mounting seat can extrude the elastic pieces so as to generate a pre-pressing elastic force, the pre-pressing elasticityenables the tensioning wh
