要約
(EN) In this excavation tool, an embedding hole (8) is provided piercing the tip of a tool main body (1) that rotates around an axis line (O) and progresses towards the tip in the axis line (O) direction, an excavation tip (5A) wherein a cylindrically-contoured embedding section (6) and a blade tip section (7) are integrally formed is inserted into the embedding hole (8) causing the embedding section (6) to be inserted into the embedding hole (8) and the blade tip section (7) to protrude from the embedding hole (8), and the excavation tip (5A) is attached in a manner so as to be able to rotate around the center line (C) of the embedding section (6) during excavation and in a manner so as to be prevented from dislocating towards the tip in the direction of the center line (C).
(ZH) 本发明的挖掘工具中,在绕轴线(O)旋转并且向轴线(O)方向顶端侧前进的工具主体(1)的顶端部穿设有埋入孔(8),一体形成有外形为圆柱状的埋入部(6)与刀尖部(7)的挖掘刀片(5A)以使埋入部(6)插入到埋入孔(8)中并且使刀尖部(7)从埋入孔(8)突出的方式安装于该埋入孔(8)中,以便在挖掘时绕埋入部(6)的中心轴(C)旋转自如且防止向中心轴(C)方向顶端侧脱落。
