DEVICE FOR ADJUSTING THE POSITION OF TWO PARTS CONNECTED TO ONE ANOTHER AND ROTATABLE AROUND THE SAME AXIS

A device is proposed for adjusting the position of two parts connected to one another and rotatable around the same axis, a first component (3, 5, 9) being a drive part and a second component (21) being a part that is to be driven. An overload coupling (11) is provided to connect the two components (3, 5, 9 and 21). The overload coupling (11) makes it possible, on the one hand, to rotate both components (3, 5, 9 and 21) jointly around the same axis of rotation and, on the other hand, to hold the first component (3, 5, 9) in place and to rotate the second component (21) for the purpose of adjusting with respect to the first component (3, 5, 9). For the purpose of rotation of the second component (21) with respect to the first component (3, 5, 9), provision is made on the second component (21) of, e.g. a projection (36) provided with a knurled finish. The angle of rotation of the first component (3, 5, 9) is fixed by two stops (37) for the first component (3, 5, 9).
