Abstract:
1. A motor-driven cutting device, in particular a hedge clipper, with a double-eccentric arrangement that moves two blades in a contra-rotating manner relative to the drive axis and oscillating toward one another, whereby the external disks lie in oblong holes of the blades and are connected in a rotationally fixed manner to one another and to a drive wheel, wherein the two eccentric discs are constructed as separate structural parts and are permanently connected under the interpositioning of an intermediate disc to the latter to a uniformly operable eccentric structural group and are coupled to the drive wheel in a rotationally fixed manner relative to the drive axis and in an axially detachable manner via cam structures and counterstructures that engage into each other axially between the eccentric structural group and the drivewheel, wherein the eccentric discs overlap in an overlapping area enclosing the drive axis in projection in the direction of the drive axis, two pin-shaped connection elements are provided in the overlapping area radially distanced from the drive axis and aligned parallel with the latter which elements permanently connect the two eccentric discs and the intermediate disc to the eccentric structural group, wherein the pin-shaped connection elements are pressed into aligned surface openings in the eccentric discs and into recesses in the intermediate disc, and wherein the connection elements project axially past the eccentric discs in the direction of the drive wheel and form the cam structures, and whereby the cam structures detachably engage into the recesses of the drive wheel that form counterstructures.
