Abstract
A device for enabling two elements connected by a knuckle to take a disalignment angle with respect to one another in a single displacement plane. One of the elements is a lower element extending beyond the knuckle and is shaped as a lever arm located in the second element which forms the upper element. The knuckle is fashioned as a ball joint, with a guiding arrangement being provided for holding the displacement of the drill elements in the displacement plane. The guiding means are integrated into the upper element and, in the upper element, a control arrangement is provided for controlling the disalignment angle with the controlling arrangement including an eccentric having the positioned determined by the disalignment angle.
