摘要： An electronic unit for a hand-held power tool, having a mounting frame having an accommodation space into which a circuit board carrying a plurality of electronic components is inserted and at least one heat sink for the heat dissipation of waste heat arising at the electronic components. A slot section with at least one insertion slot, oriented perpendicular to the printed circuit board, for mounting an electronic component along a direction of insertion is formed on the mounting frame. The at least one heat sink is associated with the slot section.

摘要： An oscillation drive with a drive and with an eccentric coupling drive for converting a rotary motion of the drive into an oscillating rotary motion of a tool spindle about its longitudinal axis is disclosed, wherein the eccentric coupling drive has an eccentric with a first eccentricity that is driven by the drive and that works together with a coupling element that is coupled to the tool spindle in order to convert the motion of the eccentric into an oscillating rotary motion of the tool spindle, wherein the eccentric is coupled to an additional eccentric with a second eccentricity so that the eccentricities are superimposed, wherein the relative position between the eccentric and the additional eccentric is adjustable to at least two different positions in order to change the amplitude of the oscillating motions of the tool spindle.
