Device for transmitting torque from drilling machine to drill bit

A device (10) for transmitting torque from a drill rig to a drill bit comprises a handle (14) and a tool fitting (13). The handle (14) is constructed by a first outer tapered region, a groove region, and a second outer tapered region, and includes a first longitudinal groove and a second longitudinal groove. The tool fitting (13) is constructed from a base body (41) having a first external rotational drive recess, an intermediate element (42) having a first internal rotational drive, a second internal rotational drive and a first external rotational drive, and a locking device (43). In the connected state, the first internal rotary driver is engaged in the first longitudinal groove, the second internal rotary driver is engaged in the second longitudinal groove, and the first external rotary driver is engaged in the first external rotary drive groove. 一种用于将转矩从钻机传递到钻头的装置(10)，该装置包括柄部(14)和工具配件(13)。柄部(14)由第一外部锥形区域、凹槽区域和第二外部锥形区域构造，并且包括第一纵向凹槽和第二纵向凹槽。工具配件(13)由基本本体(41)、中间元件(42)以及锁定装置(43)构造，该基本本体具有第一外部旋转驱动凹槽，该中间元件具有第一内
