Abstract
An elongated pole pruner for cutting and trimming trees, bushes and the like having three separable sections, that when assembled, form an extended length pruner. The pole pruner includes a first section containing a handle and battery pack, a second extension section, and a third section that contains the purner itself. Each of the sections contains an electrical conductor that is attached to corresponding conductor in an adjacent pole sections via a male plug and female receptacle. In this way, the battery pack in the first section of the pole is able to deliver power through the second section to the pruner in the third section.
Claims15
A power tool device having an adjustable length, the power tool device comprising:
- a plurality of pole sections, each having an electrical conductor therein for transferring electrical power and each of the pole sections having at least one of a male plug or a female receptacle, adjacent pole sections being non-rotatably attached to one another at connecting sections and electrically connecting the pole sections by securing the corresponding male plug and female receptacle thereon;
- and
- one of the plurality of pole sections having a power source thereon and another one of the plurality of pole sections having a power tool thereon, wherein when the pole sections are attached power from the power source is capable of being delivered to the power tool.
An extension pole adapted to extend the reach of power tools, the extension pole comprising:
- a plurality of pole sections, each having an electrical conductor therein for transferring electrical power and each of the pole sections having a connecting member on an end thereof, the connecting members capable of being attached and detached from a corresponding connecting member on an adjacent pole section to electrically connect or disconnect the adjacent pole sections, one of the plurality of pole sections adapted to have a power source thereon, and another one of the plurality of pole sections adapted to have a power tool thereon;
- connecting members having keying features thereon to prevent rotation when attached;
- and
- wherein when the pole sections are attached, power from the power source is capable of being delivered to the power tool.
