PURPOSE:To improve controllability of a machine, by removably inserting claws into a claw insertion groove provided in a claw holder and receiving these claws to be stopped by a claw receiver plate in the lower part of the claw holder so as to hold the claw. CONSTITUTION:Inserting claws 13 into an insertion groove 202 of a claw holder 201 to be held by closely contact with a receiving face 206, as the claw holder 201 turns, the claw 13 moves on the receiving face 206 while sliding in contact with said face 206. The claw 13 inserted into the groove 202 gradually lowers by its dead weight in accordance with a slope to drop down when the claw is delivered to a junction part (not shown in the drawing). A machine, the whole height of which is decreased by this amount, can be formed in a small size, and its controllability is improved by reducing machining man-hour. |
