A tool positioning apparatus permitting tool adjustment in two planes, the apparatus generally including an articulating joint apparatus and a resistance thread mechanism for rotatably positioning a tool about a central axis. In one embodiment the joint includes two halves rotatable about a central axis. The two halves are positionable through use of a push-button release that disengages a gear member and permits movement of the two halves relative to each other. In one embodiment, a gear has teeth disposed on one surface, two opposing substantially straight sides, and two opposing substantially curved sides, with a triangular protrusion mounted on each of the gear's two straight portions. The thread resistance mechanism utilizes an elastomeric threading in a narrowing taper.

The tool positioning apparatus according to claim 1, wherein said female threading is a tapered elastomeric threading. 10. A tool positioning apparatus comprising: a first housing member having an aperture, wherein said first housing member has internal surface and external surface, said internal surface having a plurality of housing teeth, said external surface bearing a female threading for attaching a tool;a second housing member, said second member in contact with and rotatable relative to said first housing member, said second member having a coupling means for attaching to a pole;a gear disposed between said first housing member and second housing member, said gear having an outwardly facing gear surface and an inwardly facing gear surface, wherein gear teeth disposed on said inwardly facing gear surface reversibly engage said housing teeth, said gear having two opposing substantially straight sides and two opposing substantially curved sides, wherein an outwardly oriented triangular protrusion is disposed at the center of each said substantially straight sides;a biasing means to urge said gear into a meshing engagement with said housing teeth;a push button disposed within said aperture of said first housing member, said push button having at least one projection for making reversible contact with the inwardly facing surface of said gear when said pushbutton is actuated, wherein the housing teeth and gear teeth are disengaged from the meshing engagement when the force from said push button is sufficient to overcome said biasing means, whereby said first and second housing members may be rotated relative to each other;a tool handle housing coupled to a tool, wherein said tool handle housing bears a male threading;wherein said female threading on said first housing member is capable of reversibly threadably engaging said male threading on said tool handle housing. 11. The tool positioning apparatus according to claim 10, wherein said biasing means is a spring means. 12. The tool positioning apparatus according to claim 11, further comprising a plurality of cylindrical housings disposed within said second housing member, wherein said spring means comprises a plurality of springs each having a first end and second end, said first end contacting said outwardly facing surface of said gear, the second end of each said spring recessed within one of said cylindrical housings. 13. The tool positioning apparatus according to claim 10, wherein said push button has four projections. 14. The tool positioning apparatus according to claim 10, wherein said first housing member has a circumferential rim and second housing member has a circumferential recess permitting the first and second housing members to rotatably engage along the perimeter of each. 15. The tool positioning apparatus according to claim 10, wherein said coupling means for attaching a pole comprises a second housing member bearing a hexagonally shaped projection having a series of progressive rib protrusions. 16. The tool positioning apparatus according to claim 10, wherein said second housing member has a central aperture. 17. The tool positioning apparatus according to claim 16, further comprising a snap axle resting within said central aperture of second housing member, said snap axle having a plurality of resilient inwardly deformable legs, each bearing an external ridge. 18.
