It is convenient for so set, pushing against rotation stop disk by rotation stop bolt to make cutter shaft not rotate when installing blade Operation.

Further setting: the end of the rotation stop bolt is provided with the intermediate plate abutted with the rotation stop side surface.

So set, increasing the contact area of rotation stop bolt and rotation stop disk by adding intermediate plate, to increase between the two Frictional force prevents rotation stop disk failure mode.

In conclusion the utility model has the following beneficial effects:

1. radiator shutter agitation air generates continuous flow, there is good heat dissipation effect to blade；

2. the adjustment of blade spacing is convenient, slitting quality is stablized, and size is accurate；

3. blade and cutter shaft stability of rotation, with small vibration.
