    摘要： A thread-cutting die head includes a die carrier supporting thread-cutting dies for displacement in a radial direction, a cam plate coaxial with the die carrier including a plurality of cam members for engaging the thread-cutting dies and displacing the cutting dies in a radial direction in response to relative rotation between the cam plate and the die carrier, and a locking system. The locking system includes a positioning screw extending through an arcuate slot in the cam plate, a cam washer surrounding the positioning screw, and a pin threaded to the positioning screw. The locking system further includes a cam handle including a cylindrical cam portion engaged with the cam washer. Rotation of the cam handle in a first direction is configured to impart a clamping force against the cam washer to lock the rotational position of the cam plate relative to the die carrier.
