As a preferred technical scheme of the utility model, the connecting hole has been seted up on the top of fixing base, a plurality of tooth's sockets have been seted up to the inner wall of connecting hole.

As an optimal technical scheme of the utility model, a plurality of blades of avris fixedly connected with of die casting body, the equidistance distributes between the blade.

As an optimized technical scheme of the utility model, the shape of tooth's socket is triangle-shaped, and every the equidistance distributes between the tooth's socket.

As a preferred technical scheme of the utility model, the other end of slide bar extends to the inside of fixed orifices, the slide bar extends to the inside one end fixedly connected with arch of fixed orifices.

As an optimal technical scheme of the utility model, the inside wall of fixed orifices is seted up flutedly, arch and recess looks adaptation.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses when using, insert the output shaft of motor in the connecting hole on die casting body top, the die casting body is fixed through the output shaft of tooth's socket with the motor, then outwards draws four pullers, inserts the epaxial connecting pin of output in the fixed orifices, then loosens the pull head, and the slide bar passes the connecting pin axle this moment to connect connecting pin axle and fixing base, current wind wheel compares, the utility model discloses need not to use connecting bolt, avoid the stopper trouble that the bolt drops and leads to, improved factor of safety.
