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.

An adjustable utility extension handle for a small electrically powered handtool, said extension handle comprising in combination: an elongated support pole having a first end and a second end; first handle means coupled to said support pole adjacent said first end thereof for being grasped by the operator to provide a first manual support point, said first handle means including first manual control means operatively interposed along an electrical conductor which supplies electrical energy to the power handtool, said manual control means for regulating the flow of electrical energy therethrough; tool coupling means for coupling with the power handtool, said coupling means further including actuating means for engaging and actuating any electrical power control regulating the power handtool; and positioning means including a pivot operatively interposed between said second end of said support pole and said tool coupling means for defining a pivot axis which limits relative motion therebetween, a reference plate coupled to said pivot and having a plurality of apertures therein, and a pin for operatively engaging one of said apertures in said reference plate, with said reference plate and said pin being operatively interposed between said second end of said support pole and said tool coupling means for controllably limiting the angular motion of the power handtool about said pivot, whereby the operator may set the required operative angular position of the power handtool adjacent the second end of said support pole and then may electrically control the operation of the power handtool from said first handle means when the power handtool is elevated into an extended operating position.
