The utility model discloses a synchronous adjusting mechanism for airflow guide blades. The synchronous adjusting mechanism comprises a driving frame, a first connecting rod and a second connecting rod, the driving frame is rotatably arranged on the impeller shell; the driving frame is provided with first connecting rods with the same number as the airflow guide blades, and the first connecting rods can rotate around connecting joints of the first connecting rods and the driving frame. Each first connecting rod is rotationally connected with one second connecting rod; and each second connecting rod is fixedly connected with one airflow guide blade. A guide rail is arranged on the impeller shell, and a roller is arranged on the driving frame; and the rollers roll along the guide rails. Compared with the prior art, each airflow guide blade is connected with the corresponding first connecting rod through the corresponding second connecting rod, all the first connecting rods are connected to the driving frame, an
