The second control device (4) is moveable in translation, and the hammer or hammers (5) are pivotable about a respective pivot or pivots (17) that are independent of the second control device (4), and are hinged to the second control device (4) in order to be able to be pivoted about the pivot or pivots (17) by a translational movement of the second control device (4).
