发明名称 Adjustable utility extension handle for electrically powered handtool
摘要 The present invention relates to an adjustable utility extension handle for a small electrically powered handtool. An elongated support pole is provided having a first handle coupled to a lower end thereof for being grasped by the operator to provide a first manual support point. A second handle is movably mounted along the pole for providing a second manual support point. The first handle includes a power regulating device which is interposed along an electrical conductor which supplies electrical power to the power handtool, thereby allowing the operator at the lower end of the elongated support pole to regulate the speed of the power handtool. A tool coupler is removably attached to the power handtool. The tool coupler includes an actuator for engaging and fully actuating any electrical power control which regulates the operation of the power handtool. A positioning device is operably coupled to the second end of the support pole and to the tool coupler for regulating the operative angular position therebetween. In this manner the operator may set the required operative angular position of the power handtool adjacent the second end of the support pole, and then may electrically control the operation of the power handtool from the first handle when the power handtool is elevated to an extended operating position.
