Connecting rod type wind turbine blade adjusting mechanism and using method

The invention provides a connecting rod type wind turbine blade adjusting mechanism and a using method. The connecting rod type wind turbine blade adjusting mechanism comprises a power unit of which a main shaft is horizontally arranged, a machine base, a driving motor fixing plate, a cabin cylinder wall, a front end cover, a coupler, a supporting mechanism, a screw-nut mechanism, a sliding mechanism and a connecting rod mechanism. The coupler is connected with the driving motor fixing plate and the supporting mechanism. The sliding mechanism is connected with the screw-nut mechanism. The connecting rod mechanism is fixed to the sliding mechanism. By changing the structure of the blade adjusting mechanism and changing the transmission mode, the blade shake quantity is reduced, and the stability and accuracy of transmission are improved.
