A device for converting a rotational movement into a rotatively oscillating movement, comprising A) a drive shaft (2) with a longitudinal axis (3), a rear end (21), which can be connected with a drive unit, a front end (22) and an eccentrically disposed pivot (6), the axis (7) of which is parallel to the longitudinal axis (3) and which is disposed eccentrically at the front end (22); B) a second, rotatively oscillating shaft (5) with a front end (23), which can be connected with a tool or instrument, and a rear end (24); C) a driving mechanism (1), which is disposed between the front end (22) of the drive shaft (2) and the rear end (24) of the second shaft (5), for converting the rotative movement of the drive shaft (2) into the rotatively oscillating movement of the second shaft (5); and D) a housing (4), in which the drive shaft (2) and the second shaft (5) are mounted so that they can be rotated about the longitudinal axis (3); E) the gearing mechanism (1) comprising a movable lever (9), which is mounted movably at the catch (12), at the housing (4) and at the pivot (6), F) the lever (9) being disposed transversely to the longitudinal axis (3). |
