ABSTRACT:
When pairs of fingers grasp tools and a tool exchange arm starts lowering, upper ends of lock pins which have been held by a spindle head are released, the lock pins are pushed up by urging forces of springs, and tapered portions of the lock pins push out steel balls to external sides. Thus, cylindrical portions of the pairs of fingers are prevented from opening, and opening and closing of the pair of fingers are locked.
