The invention discloses a movable blade swing control adjusting system of an axial flow fan. The movable blade swing control adjusting system comprises blades, and the bottom ends of the blades are welded to a rotating rod; the impeller is clamped between the hubs; the cylinder body is mounted on the right end surface of the impeller in a sliding manner; one end of the fixing shaft is inserted into the cylinder body; one end of the main shaft penetrates through the hub on the left side; the expansion part is located on the right side of the partition plate; an air outlet of the air pump is connected with the air pipe; and the controller is connected with the air pump, the pipe valve and the distance measuring instrument. According to the movable blade swing control adjusting system of the axial flow fan, air is injected into the expansion piece through the air pump, so that the size of the expansion piece is changed, the expansion piece is used for pushing the second magnetic plate to move, and the swing angl
