Jigsaw with a stroke movement of the plunger produced by a Scotch-yoke mechanism

摘要

The object of the invention is to enable the plunger stroke to be adjusted in a simple manner. The invention achieves this object by the eccentric pin (12) being attached to a disc (11) which is combined with the drive gear (1) in such a way as to be pivotable relative to the drive gear about an axis (9) lying eccentrically to the axis (8) of the drive gear (1) and which has two stop surfaces (17, 18), of which, depending on the direction of rotation of the drive gear (1), in each case one comes to bear on a driving pin (16) located on a radius of the drive gear. <IMAGE>
