項(1)記載の爪チヤツク。[Scope of Claim for Utility Model Registration] (1) A master pawl that applies driving force by slidably assembling the chuck pawl into the radial guide groove of the chuck body, and a workpiece gripping pawl that engages in serration on the upper surface of the master pawl. In the pawl chuck, which is made up of two parts and which are fastened together with bolts, a guide hole is provided at the axial center of the main pawl and opens at the rear surface of the pawl, and a guide hole opening in the rear surface of the pawl is provided on the top surface of the main pawl with an axial width smaller than the diameter of the guide hole. A long hole is provided at a predetermined distance from the front and rear edges, a seat nut with a similar cross-section and a slightly smaller diameter than the hole diameter is inserted into the guide hole, and a workpiece is gripped by the threaded hole provided in the seat nut in the direction perpendicular to the axis. A claw chuck characterized in that a fixing bolt of the claw is inserted into the main claw through the elongated hole and screwed together. (2) A screw hole is provided on the rear surface of the above-mentioned seat nut, and a retaining member is provided on the outer periphery of the chuck body. According to claim (1), the pulling bolt is held back and the tip of the bolt is screwed into the threaded hole on the rear surface of the seat nut, so that a force in the chuck radial direction can be applied to the master pawl via the pulling bolt. 's nail chuck.
