Abstract: A cutter includes a cutter handle and cutter head including a main body and a plurality of curved cutting edges separately extending from a periphery of the main body. Each cutting edge has a top surface, a first side blade surface, a second side blade surface, and a bottom surface. The top surface, the first side blade surface, the second side blade surface, and the bottom surface intersect to form a front edge, a middle edge, and a back edge. The front edge, the middle edge, and the back edge cooperatively form an edge tip. A tangent of the middle edge at the edge tip intersects with the bottom surface to form a cutting angle in a range from 30° to 60°.

Abstract: A fixing mechanism includes a first fixing plate, a second fixing plate corresponding to the first fixing plate, and a screw connecting the first fixing plate and the second fixing plate. The first fixing plate defines a receiving hole comprising a connecting portion. The second fixing plate defines a locking hole corresponding to the connecting portion. The screw comprises a threaded shank matching with the connecting portion and the locking hole. The fixing mechanism further comprises an elastic member positioned in the receiving hole, the threaded shank abuts against the corresponding elastic member, and an elastic resistance of the elastic member limits back and forth movement of the screw.

Abstract translation: 固定机构包括第一固定板，对应于第一固定板的第二固定板和连接第一固定板和第二固定板的螺钉。 第一固定板限定包括连接部分的容纳孔。 第二固定板限定对应于连接部分的锁定孔。 螺钉包括与连接部分和锁定孔匹配的螺纹柄。 固定机构还包括定位在容纳孔中的弹性构件，螺纹杆抵靠相应的弹性构件，并且弹性构件的弹性阻力限制了螺杆的前后运动。
