Abstract
A motor unit has a tool for engaging a work piece with a frame unit, which has a gripping element for the handheld operation of the device, wherein a mechanical coupling is provided between the motor unit and frame unit, which encompasses at least one dampening element, in such a way that makes it possible to precisely guide the tool while improving the dampening of vibrations between the motor unit and frame unit. The frame unit has at least one abutting element, against which the motor unit abuts when a working force exerted by the work piece on the tool has a value below a minimum value.
Claims18
A motorized working tool comprising:
- a motor unit;
- a tool for engaging a work piece;
- a frame unit with gripping element;
- and
- a mechanical coupling provided between the motor unit and the frame unit, which includes at least one dampening element, wherein:
- the frame unit includes at least one abutting element, against which the motor unit abuts when a working force exerted between the work piece and the tool is below a minimum value and
- the minimum value is a force, at which the motor unit starts to detach from the abutting element, wherein
- the motor unit includes at least one support element, which abuts against the abutting element when the working force is below the minimum value.
