摘要： 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).

摘要： A blade assembly of a hedge trimmer includes at least one cutting blade having cutting teeth. At least one portion of the cutting teeth are configured as protective teeth which, referred to the cutting blade axis, have an inner cutting region and from which an outer protective finger extends. The protective tooth is, referred to its tooth axis, configured unsymmetrically. The protective tooth has a cutting side and an opposite-lying holding side and a cutting edge in the cutting region on the cutting side and a holding edge on the holding side. The protective finger has a forward edge on the cutting side and a rearward edge on the holding side. Starting from the blade axis, the forward edge is inclined to the tooth axis and the rearward edge, starting from the blade axis, is inclined away from the tooth axis.

摘要： A hedge trimmer having a rear handle, a tubular handle and a blade arrangement with at least one cutter bar disposed in a cutter bar plane. An internal combustion engine drives the cutter bars in a reciprocating manner, and has a combustion chamber and a crankshaft mounted in a crankcase so as to be rotatable about an axis of rotation. The combustion chamber faces the rear handle, and the crankcase faces the blade arrangement. The blade arrangement has a longitudinal central axis, and the hedge trimmer has a longitudinal plane that is disposed parallel to the axis of rotation of the crankshaft and transverse to the cutter bar plane. The longitudinal central axis of the blade arrangement lies in the longitudinal plane of the hedge trimmer.
