摘要： An insert chaser die head having a main frame member to which is attached a control plate having at least one guiding groove on its front face and rotating plate means positioned adjacent said control plate. The rotating plate means has at least one bore therein for supporting an actuating pin member whose end travels in the guiding groove and is biased by a spring located in the groove. At least two more bores are formed in the rotating plate for supporting at least two driven pin members, so that a portion of the ends of the pin members protrude from the rotating plate means. A stationary body member mounted adjacent the rotating plate means has at least two channels for slidably supporting at least two carrier members which, in turn, support individual chasers for cutting threads on workpieces. Individual guideways communicating with each channel are formed in the body member to permit the ends of the driven pin members to pass therethrough and engage cam grooves in the carrier members such that, upon rotation of the rotating plate means, the carrier members are moved toward or away from each other.
