    摘要： A cutting tool includes a chuck, a compressible conical collet and a lock nut for locking the collet. The cutting tool lock nut has a nut portion with a threaded portion for threading with the chuck, and a locking portion with a collet-locking surface formed with angled coolant grooves thereon. The collet-locking surface presses on the collet head, thereby compressing it to grip a tool shank in a collet bore thereof. As the locking portion presses only against a peripheral surface of the collet head, the lock nut is suitable for locking collets with different bore diameters. When the chuck is provided with a coolant fluid, the coolant fluid flows through the chuck and through the collet towards the locking portion, passing through the coolant notches between the locking portion and the collet head, and sprayed towards a location along the tool shank.

    摘要翻译： 切割工具包括卡盘，可压缩锥形夹头和用于锁定夹头的锁紧螺母。 切割工具锁定螺母具有螺母部分，螺母部分用于与卡盘螺纹连接，以及具有夹紧锁定表面的锁定部分，其上形成有倾斜的冷却剂槽。 夹头锁紧表面压在夹头上，从而压紧夹头，以夹紧其夹头孔中的工具柄。 当锁定部分仅压靠夹头的周面时，锁紧螺母适合于锁定具有不同孔直径的夹头。 当卡盘设置有冷却剂流体时，冷却剂流体流过卡盘并通过夹头朝向锁定部分，穿过锁定部分和夹头之间的冷却剂槽口，并朝着沿着工具柄的位置喷射。

    摘要： A chuck for use with a driver, the chuck including a body having a nose section defining an axial bore and a tail section. A plurality of jaws is in communication with the axial bore. A first sleeve is rotatably mounted to the body so that rotation of the sleeve moves the jaws either toward or away from a longitudinal center axis of the axial bore. A second sleeve is rotatably mounted to the body and is movable between a first position in which the second sleeve is rotatably fixed to the body and a second position in which the second sleeve is rotatable about the body. The second sleeve moves in a direction transverse to the longitudinal center axis of the axial bore when moving between the first position and the second position.

    摘要： A tool holding module comprises a fixture seat and a tool rod. The fixture seat has a first outer surface on an external wall, a first top surface on one end, and a fixture head is located on the same end. The fixture head has a second outer surface on an external wall and a second top surface on one end. The internal wall of the tool rod has first and second inner surfaces respectively corresponding to the first and second outer surfaces, and has first and second butting surfaces respectively corresponding to the first and second top surfaces. The tool rod and fixture seat are connected to enfold the fixture head.
