摘要： A chuck body is formed with angled guides holding respective jaws. A tightening ring rotatable about the axis on the chuck body has a screwthread meshing with toothed edges of the jaws so that rotation of the ring in one direction moves the jaws axially forward and radially together and opposite rotation moves the jaws axially rearward and radially apart. A spring washer is rotatable about the axis on the body between the tightening ring and the rear jaw faces. Rearwardly directed jaw faces axially rearwardly engage and press the washer toward the tightening ring and coupling formations on the washer and ring angularly lock the washer to the ring when the washer is pressed axially rearward by the faces. Stops on the washer can engage the jaws for permitting only limited relative angular movement of the washer and jaws when the faces are pressed axially rearward against the washer.
摘要翻译：卡盘体形成有夹持相应夹爪的成角度的导向件。可绕卡盘主体的轴线旋转的紧固环具有与钳口的齿形边缘啮合的螺纹，使得环在一个方向上的旋转使轴向轴向向前和径向地移动，并且相反的旋转使卡爪轴向向后和径向分开。弹簧垫圈能够围绕紧固环和后爪面之间的主体上的轴线旋转。向后定向的颚面轴向向后接合并将垫圈压向紧固环，并且当垫圈被面向轴向向后挤压时，垫圈和环上的联接结构将垫圈角度地锁定到环上。垫圈上的止动件可以接合夹爪，以便当面朝向垫圈轴向向后挤压时，仅允许垫圈和夹爪的有限的相对角度运动。
