    摘要： A blower is provided having a plurality of tubular nozzles removably attachable to the blower enabling an operator to easily vary the velocity and air discharge pattern. The blower forms part of an operator carried power tool having a drive motor spaced from the blower assembly by a tubular boom containing a drive shaft. The blower comprises a blower housing having an axial air inlet and an air outlet defined by a tubular section. An impeller is pivotally mounted within the blower housing and driven by the drive shaft. As the impeller is rotated, air is drawn through the air inlet and discharged through one of a plurality of tubular nozzles mounted on the blower housing tubular section. Tubular nozzles have varying geometries to conveniently vary the discharge air pattern.

    摘要翻译： 提供鼓风机，其具有可拆卸地附接到鼓风机的多个管状喷嘴，使得操作者能够容易地改变速度和空气排放模式。 鼓风机形成操作者承载的动力工具的一部分，该工具具有驱动马达，该驱动马达通过包含驱动轴的管状悬臂与鼓风机组件隔开。 鼓风机包括具有轴向空气入口和由管状部分限定的空气出口的鼓风机壳体。 叶轮枢转地安装在鼓风机壳体内并由驱动轴驱动。 当叶轮旋转时，空气通过空气入口抽出并通过安装在鼓风机壳体管状部分上的多个管状喷嘴中的一个排出。 管状喷嘴具有不同的几何形状以方便地改变排出空气模式。

    摘要： A battery powered line trimmer having a forward and rearward handle attached thereto, and further having an arm cradle atop the battery casing allowing the operator to rest his forearm upon it during operation. The arm cradle allowing the operator to maintain control of and maneuver the line trimmer by using the rear handle and arm cradle should the need arise for him to release his grip of the forward handle while cutting vegetation. The line trimmer further has a relatively high ratio of mass movement of inertia about a vertical axis extending through the center of gravity to mass of the line trimmer.
