Abstract

The invention relates to a portable power tool (2) comprising a drive motor and a tool (4) which is driven by the drive motor and which, during operation of the drive motor, performs an oscillating movement, on which a pendulous movement is superimposed. Provision is made for the tool (4) to move in a pendulous manner about a pivot axis (40) which moves back and forth along a path (44) of motion.

Description

technical field [0001] The invention relates to a hand-held power tool according to the preamble of claim 1 . Background technique [0002] Oscillating-stroke jigsaws are known, in which the saw blade performs an oscillating movement along its longitudinal axis, wherein a pendulum movement is superimposed on this oscillating movement, so that the saw-toothed edge of the saw blade acts on the workpiece during its cutting stroke and returns Lift slightly from workpiece during stroke. [0003] Although workpieces can be cut with this and other jigsaws, it is not possible to create or machine grooves in the workpiece. Furthermore, known jigsaws are only equipped with saw blades and are used for cutting workpieces, but are not suitable for other material processing methods, such as grinding or scraping. [0004] Proceeding from this, the object of the present invention is then to develop the hand-held power tool mentioned in the opening paragraph in such a way that, on the one ...
