Of the present utility model it is further arranged to: described linkage component includes the master gear being arranged in the described rotating shaft outside described ventilation shaft and for connecting the linkage gear of master gear described in engagement adjacent.
By using technique scheme, during axis of rotation, master gear rotates, and the linkage gear engaged with master gear drives another master gear engaged, and both link, when making to rotate with the blade rotating bar, the blade the being adjacent linkage by master gear, it is achieved simultaneously rotate, after rotation bar is fixing, master gear realizes fixing, and adjacent blade also realizes the fixing of angle.
Of the present utility model it is further arranged to: be rotationally connected by bearing between described rotating shaft and described ventilation shaft.
By using technique scheme, rotating shaft is put on record on the sidewall of ventilation shaft by bearing, it is ensured that axis of rotation is the most smooth, also achieves the axial restraint rotated simultaneously.
Of the present utility model it is further arranged to: the two side of described blade is provided with rubber strip.
By using technique scheme, on the one hand the rubber strip on blade abuts with the inwall of ventilation shaft does not grudges the sealing effectiveness of blade more preferably, and the rubber strip of adjacent blades the same side can heighten sealing between the two simultaneously.
In sum, this utility model has the advantages that by this elastic component so that rotating location dish on bar and ventilation shaft and realize fixing, fixed form is stable, and only need to press and can realize location or separate；Simultaneously because the location pore size distribution on the dish of location is multiple and circumferentially distributed so that blade has multiple different distribution, easy to operate.
