The invention relates to a two-for-one twister with a movable suction fan. The two-for-one twister comprises a two-for-one twister body (1) and is characterized in that a guide rail (2) is arranged along the length direction at the top of the two-for-one twister body (1), a suction fan (3) is arranged on the guide rail (2), two air suction pipes (4) respectively extend out from the suction fan (3) towards the two sides of the two-for-one twister body (1), and the lower ends of the air suction pipes (4) are downwards and vertically arranged. Since the movable suction fan is arranged at the top of the two-for-one twister body, the air suction pipes of the suction fan can suck dust around the two-for-one twister in time. Therefore, the two-for-one twister with the movable suction fan has the advantages that the labor is greatly saved, the dust is removed in time and the dust removing effect is ideal.
