| 摘要 |
The invention relates to a cutting assembly (4) for a portable hand- held power driven working tool. The cutting assembly (4) comprises a first elongate cutting blade (9) and a second elongate cutting blade (10). The cutting blades (9, 10) are arranged to be connected to a gear, causing the cutting blades (9, 10) to move in a reciprocal manner along a longitudinal axis of the cutting blades (9, 10). The cutting blades (9, 10) are arranged to be mounted so that an interior surface (11)of the first cutting blade (9) faces towards and abuts on an interior surface (12)of the second cutting blade (10), wherein at least one of the cutting blades (9, 10) has a recess (13, 14) extending in a longitudinal portion of the interior surface (11, 12) of the cutting blades(9, 10), such that a gap (15) appears between the cutting blades (9, 10) when they are mounted in a face-to-face relationship. The gap (15) prevents the flow of the grease from the gearbox (7) beyond the position of the gap (15) on the cutting assembly(4). |
