And the plurality of second through-holes 181 formed in the flanges 142 are arranged to be in-line with each other along the longitudinal direction of the rotation shaft 141 .

Accordingly, the stoppers 180 are fixed by being inserted into the second through-holes 181 formed on the plurality of flanges 142 and arranged to be in-line with each other along the longitudinal direction of the rotation shaft 141 . In fixing the stoppers 180, both ends of each of the stoppers 180 are detachably fixed by the second fixing pin 182 to the flanges 142 located at the outermost sides of both sides among the plurality of flanges 142. can

In particular, it is possible to install the stoppers 180 at positions that allow the grinding blades 148 to maintain a standing state. At this time, each of the stoppers 180 is in contact with one side of the grinding blades 148 , and in this case, the grinding blades 148 are arranged in parallel with the radial direction of the rotation shaft 141 .

As such, the present invention is not limited to the described embodiments, and it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, it should be said that such modifications or variations are included in the claims of the present invention.
