摘要： A multi-purpose tool (10) is used as an air blower capable of delivering a high-velocity stream of air when in a blower mode of operation and as a rotating string trimmer capable of trimming vegetation when in a trimmer mode of operation. The tool has a blower housing (18) including an enclosed chamber (30), a plurality of vents (35) leading to the chamber, and a blower nozzle (32) for directing air from the chamber, wherein the impeller (20) is rotatably mounted in the chamber such that the housing defines an air pathway between the vents and the impeller. The multi-purpose tool also includes means (82) for blocking the flow of air between vents and the impeller when in the trimmer mode of operation and means (99, 124) for disengaging the trimmer head (22) from the internal drive shaft (26) when in the blower mode.
摘要翻译：使用多用途工具（10）作为在鼓风机运行模式下能够输送高速空气流的鼓风机，以及当处于微调操作模式时能够修剪植被的旋转弦修剪器。所述工具具有鼓风机壳体（18），所述鼓风机壳体（18）包括封闭室（30），通向所述室的多个通风口（35）和用于引导来自所述室的空气的鼓风机喷嘴（32），其中所述叶轮（20）可旋转地安装在腔室中，使得壳体限定通气口和叶轮之间的空气通路。所述多功能工具还包括用于当处于微调操作模式时阻止通风口和叶轮之间的空气流动的装置（82）和用于使修剪器头部（22）与内部驱动轴（22）分离的装置（99,124） 26）当在鼓风机模式。

摘要： A multi-purpose tool powered by an attached power source is used as an air blower capable of delivering a high-velocity stream of air when the multi-purpose tool is in a blower mode of operation and as a rotating string trimmer capable of trimming vegetation when in a trimmer mode of operation. The tool includes a tubular shaft boom and an internal drive shaft configured to be rotated by the power source, and an impeller operatively connected to the internal drive shaft so as to be rotatable within the chamber and a trimmer head positioned below the impeller, the trimmer head operatively connected to the internal drive shaft so as to be selectively rotatable by the power source. The tool also has a blower housing positioned at a distal end of the shaft boom including an enclosed chamber, a plurality of vents leading to the chamber, and a blower nozzle for directing air from the chamber, wherein the impeller is rotatably mounted in the chamber such that the housing defines an air pathway between the vents and the impeller. The multi-purpose tool also includes means for blocking the flow of air between vents and the impeller when the multi-purpose tool is in the trimmer mode of operation and means for disengaging the trimmer head from the internal drive shaft when the multi-purpose tool is in the blower mode.
摘要翻译：使用由附加电源供电的多用途工具用作当多用途工具处于鼓风机操作模式时能够输送高速空气流的鼓风机，以及能够修剪植被的旋转弦修剪器当处于微调操作模式时。该工具包括管状轴臂和构造成由动力源旋转的内部驱动轴，以及可操作地连接到内部驱动轴以便在腔室内旋转的叶轮和位于叶轮下方的修剪器头部的修剪器头部可操作地连接到内部驱动轴，以便由电源选择性地旋转。所述工具还具有定位在所述轴臂的远端处的鼓风机壳体，所述鼓风机壳体包括封闭室，通向所述室的多个通风口和用于引导来自所述室的空气的鼓风机喷嘴，其中所述叶轮可旋转地安装在所述室中使得壳体限定通气口和叶轮之间的空气通路。多用途工具还包括当多功能工具处于微调操作模式时阻止通风口和叶轮之间的空气流动的装置，以及当多用途工具处于鼓风机模式。
