Of the present utility modelly to be set to further: described petiole shaft one end be positioned on body is provided with the circular groove matched with fixing rod caliber.
By adopting technique scheme, fixing rod better can fix petiole shaft by the circular groove on petiole shaft, effectively prevents petiole shaft from loosening.
Of the present utility modelly to be set to further: the two ends of described fixing rod are provided with the clamping bolt being fed through two ends after body for being fastened and fixed bar.
By adopting technique scheme, realized the means of fixation of fixing rod by clamping bolt, easy installation and removal.
Of the present utility modelly to be set to further: described body is also provided with the groove between two fixing rods, the bottom surface of described groove is higher than the lowest surfaces of mounting groove.
By adopting technique scheme, groove can play the effect of strengthening body structure intensity, also plays the effect of draining simultaneously.
Of the present utility modelly to be set to further: described mounting groove quantity is 8, and 6 described mounting grooves are evenly distributed on body, and all the other two lay respectively between wantonly one or two mounting groove.
By adopting technique scheme, the distribution of installation shaft makes petiole shaft have more mounting type.
The utility model has following advantage: can effectively be arranged on wheel hub by petiole shaft by inverted U fixing rod, and compared to prior art, realize the single replacing of petiole shaft, the detachable setting of petiole shaft and blade, makes maintain and replace more convenient.
