[0043] When in use, since one end of the hub 101 needs to be connected to the main shaft of the power generator, the other end of the hub 101 is set as a deflector, and the setting of the deflector can reduce wind resistance. First, place the hub 101 deflector on the ground with one end facing upward, and then align the three blade openings 102 in sequence to install the three blades 103 on the hub 101 in advance, and then put the device on the hub 101. After the annular frame 201a is put on the hub 101, start the motor 201c to drive the three gears and the annular gear 201d to rotate, thereby driving the three turntables 202a to rotate, so that the three groups of arc clamps 202d move synchronously towards each other, clamping and fixing the blades 103, so that when the hoisting equipment is used to lift the annular frame 201a, the hub 101 and the three blades 103 are lifted as a whole, and then the three blades 103 can be fully installed by only one hoisting and lifting, and the installation efficiency is high.
