Abstract

PURPOSE: To uniformly and strongly hold and to obtain a twisted square bar having good surface finishing by providing the vice claw for abutting the side face of a square bar in the same number as the number of side faces of the square bar and sliding the abutting face made by exceeding the square bar side face of the vice claw with the side face of the adjacentmost vice claw.
CONSTITUTION: The vice claw 5 in the same number as the number of side faces of a square bar 9 is provided at the holding part of the other part of a square bar separated with receiving a twisting movement relatively to one part of the holding part. The abutting face 5c made by exceeding the side face 9a of the square bar of the vice claw 5 with the end edge 5b of one part of the abutting face 5a to the square bar 9 and the end edge 9b of one part of the side face 9a of the square bar being coincident is slid with the side face 5d of the adjacentmost vice claw 5 on any vice claw 5 as well. Thus, the vice claw 5 abutts the whole peripheral face of the square bar 9 side face, interposing the square bar 9 by pressing it uniformly and strongly.
