Hand-held and hand-guided power tool having a working element releasably attached thereto, and for such a power tool

Hand-held machine tool (1) for sanding or polishing a workpiece, the hand-held machine tool (1) comprising:

• a housing (2),
• a motor (4) for actuating a tool shaft (5) of the hand-held machine tool (1) and for making the tool shaft (5) rotate about its axis of rotation (6), and
• a backing pad (3) for releasable attachment of a sanding element or a polishing element thereto and eccentrically attachable to the tool shaft (5) by means of an eccentric element (11) in such a way as to allow the backing pad (3) to perform a working movement,
• wherein the hand-held machine tool (1) is adapted for realizing two different types of working movements of the backing pad (3) attached thereto,
• wherein the housing (2) of the hand-held machine tool (1) comprises a plurality of first magnetic elements (16) facing the backing pad (3), and that the backing pad (3) attached to the eccentric element (11) comprises a plurality of second magnetic elements (17) facing the housing (2), and
• wherein the hand-held machine tool (1) is adapted for realizing a first type of working movement if a magnetic force is active between at least some of the plurality of the first and second magnetic elements (16, 17) and a second type of working movement if no magnetic force is active between the plurality of the first and second magnetic elements (16, 17).
