A screw portion 41 is provided on the bottom surface of the jaw 40 so as to be screwed into the screw groove 21 of the fixing plate 20 described above.

Hereinafter, a method of setting a workpiece on a conventional interlocking chuck 1 will be described with reference to the drawings.

When the fixing gear 11 of the coupling body 10 is rotated in one direction or the other direction with the circular rod shaped workpiece set in the coupling hole 31, the fixing plate 20 rotates in the circumferential direction.

Accordingly, since the threaded portion 41 of the jaw 40 is gear-engaged with the thread groove 21 formed on one surface of the fixed plate 20, the plurality of jaws 40 fix the workpiece provided in the center.

Thus, when the workpiece is fixed, the main shaft (not shown) of the lathe is rotated to machine the workpiece.
