    • 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).
    • 本发明涉及一种用于便携式手持式动力驱动工作工具的切割组件(4)。 切割组件(4)包括第一细长切割刀片(9)和第二细长切割刀片(10)。 切割刀片(9,10)被布置成连接到齿轮,使得切割刀片(9,10)沿着切割刀片(9,10)的纵向轴线以往复的方式移动。 切割刀片(9,10)被布置成被安装成使得第一切割刀片(9)的内表面(11)朝向并邻接第二切割刀片(10)的内表面(12),其中 至少一个切割刀片(9,10)具有在切割刀片(9,10)的内表面(11,12)的纵向部分中延伸的凹部(13,14),使得间隙(15) )出现在切割刀片(9,10)之间,当它们以面对面的关系安装时。 间隙(15)防止来自齿轮箱(7)的润滑脂超过切割组件(4)上的间隙(15)的位置。
