如圖4所示，當更換為另一規格的切斷片60A時，其中該切斷片60A的通孔61A小於前述切斷片60的通孔61時，該切斷片60A的通孔61無法套設於該至少一結合凸部11而是套設該旋轉軸10的固定部12，透過該定位件31內側面抵靠於該切斷片60A的力量，並讓該切斷片60A與該旋轉軸10的至少一結合凸部11相互抵靠，以及搭配該鎖固件32的鎖固力量，讓該切斷片60A能夠穩固地設置於該定位件31與該旋轉軸10之間，且該切斷片60A同樣能與該旋轉軸10同步轉動。 As shown in FIG. 4, when the cutting piece 60A of another specification is replaced with the through hole 61A of the cutting piece 60A smaller than the through hole 61 of the cutting piece 60, the through hole 61 of the cutting piece 60A cannot be sleeved. The at least one coupling protrusion 11 is sleeved with the fixing portion 12 of the rotating shaft 10, and the inner side of the positioning member 31 abuts against the cutting piece 60A, and the cutting piece 60A and the rotating shaft 10 are at least A coupling protrusion 11 abuts against each other, and the locking force of the locking member 32 allows the cutting piece 60A to be stably disposed between the positioning member 31 and the rotating shaft 10, and the cutting piece 60A can also be The rotating shaft 10 rotates in synchronization.
相較於現有切斷片90或研磨片的通孔91更換另一規格時，因現有切斷機或平面研磨機的定位結構70的旋轉軸71之固定部711尺寸與該切斷片90或研磨片之通孔91的尺寸相互配合，故當切斷片90或研磨片更換規格時，該定位結構70的旋轉軸71需進行更換並重新安裝一相對應的尺寸，造成現有切斷機的定位結構70在使用上不便利，本新型利用該至少一結合凸部11搭配該固定部12的設計，讓不同規格之切斷片60、60A或研磨片的通孔61、61A皆能穩固地套設於該至少一結合凸部11或該固定部12，故當更換該切斷片60、60A或研磨片的規格時，該旋轉軸10無需重新安裝，而增加使用上的便利性，且該定位件31與該鎖固件32亦能增強該切斷片60、60A或研磨片與該旋轉軸10以及該定 位件31之內側面間的摩擦力，確保該切斷片60、60A或研磨片能夠穩定地與該旋轉軸10同步轉動。 The size of the fixing portion 711 of the rotating shaft 71 of the positioning structure 70 of the conventional cutter or the plane grinder is different from that of the cutting piece 90 or the polishing sheet, compared to the conventional cutting piece 90 or the through hole 91 of the polishing sheet. The through holes 91 are sized to match each other. Therefore, when the cutting piece 90 or the polishing piece is changed in size, the rotating shaft 71 of the positioning structure 70 needs to be replaced and reinstalled with a corresponding size, resulting in the positioning structure 70 of the existing cutting machine. In the inconvenient use, the present invention utilizes the design of the at least one coupling protrusion 11 and the fixing portion 12, so that the different sizes of the cutting piece 60, 60A or the through holes 61, 61A of the polishing piece can be stably set on the same. At least one of the convex portion 11 or the fixing portion 12 is coupled, so when the specification of the cutting piece 60, 60A or the polishing sheet is changed, the rotating shaft 10 does not need to be reinstalled, and the convenience in use is increased, and the positioning member 31 and the positioning member 31 are The locking member 32 can also reinforce the cutting piece 60, 60A or the grinding piece and the rotating shaft 10 and the fixing The frictional force between the inner side surfaces of the bit members 31 ensures that the cut pieces 60, 60A or the polishing sheets can stably rotate in synchronization with the rotary shaft 10.
