It states the meshing bevel gear II under the drive of knife handle of bevel gear I and drives driven shaft rotation, the driven shaft drives driving wheel rotation, institute
It states driving wheel and driven wheel rotation is driven by synchronous belt, the driven wheel drives polishing wheel rotation；
Preferably, fastening bolt is unclamped, rotatable housing I adjusts the angle of polishing wheel around the axis rotation of knife handle, completes
After adjustment, screws fastening bolt and hold lantern ring on shell I tightly；
Preferably, the angle of the polishing wheel required for the position for the workpiece to be polished cannot be completed by rotation shell I
When, the different polishing wheel buff unit of angle between the axis of replaceable knife handle and the axis of driven shaft repeats above-mentioned behaviour
Make.
