要約
(EN) In an excavation tool of the present invention, an embedding hole 8 is drilled in a distal end portion of a tool body 1 which is rotated about an axis line O and is moved forward to a distal end side in a direction of the axis line O. In the embedding hole 8, an excavation tip 5A in which an embedding portion 6 having an outer cylindrical shape is formed integrally with a cutting edge portion 7 inserts the embedding portion 6 into the embedding hole 8 and causes the cutting edge portion 7 to protrude from the embedding hole 8. In this manner, the excavation tip 5A is rotatable around a central axis C of the embedding portion 6 during excavation, and is attached thereto by being locked so as not to slip toward a distal end side of the embedding portion 6 in a direction of the central axis 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。
