By adopting the scheme, the impeller and the impeller rotating shaft support can be prevented from rotating relatively through the arrangement of the limiting column.

The utility model discloses an above-mentioned technical scheme's beneficial effect as follows:

in the scheme, the impeller rotating shaft is conveniently clamped in the sleeve through the matching of the sleeve, the bolt hole, the pressing plate, the limiting column, the mounting plate, the rotating handle and the first bolt, then the impeller rotating shaft and the sleeve are fixed together through the first bolt, other bolts penetrate through the bolt holes to be fixed with the impeller rotating shaft, the connection between the sleeve and the impeller rotating shaft is further enhanced, the fixing ring can tightly press the impeller on the impeller rotating shaft, the limiting column is clamped in the clamping hole on the impeller, and therefore the impeller and the impeller rotating shaft are prevented from rotating relatively;

through the cooperation between fixed plate, stopper and the spacing groove, after being in the same place first bolt and impeller pivot are fixed, overlap the fixed plate in the outside of the bolt head of first bolt again for the limiting plate card is in the inside of spacing groove, and is in the same place fixed plate and mounting panel are fixed again, thereby avoids first bolt to take place to become flexible

The utility model discloses rational in infrastructure, design benefit, easy operation, not only can be convenient lock the impeller, easy dismounting easily uses widely moreover
