Abstract:
The invention relates to an eccentric gear arrangement of a motor-driven, hand-guided hedge trimmer (1). The eccentric gear arrangement includes two shearing blades (2, 3) driven in mutually opposite directions over a displacement path (a). Each shearing blade has a connecting link (4, 5) as well as an eccentric wheel (6) having a drive wheel (7) and two eccentrics (8, 9). The eccentric wheel (6) rotates about a rotational axis (10). The two connecting links (4, 5) lie directly above one another. The two eccentrics (8, 9) are arranged on the same side of the drive wheel (7) and engage each in one of the two connecting links (4, 5). The two shearing blades (2, 3) have contact pressure surfaces (11, 12) in the region of their two connecting links (4, 5) and are offset with respect to each other in such a manner that they are exposed at least over a portion of the displacement path (a). Two downholders (13, 14) are provided which act each on one of the assigned contact pressure surfaces (11, 12).
