Abstract:
1. An extension tool, comprising: a first pole defining an interior bore and a first exterior surface with said first pole extending between a first end and a second end; a second pole defining a second exterior surface with said second pole extending between a first end and a second end; said second pole being partially disposed in said first pole for defining a variable overall tool length; a slide controller including a lower clamp and an upper clamp; said lower clamp having a primary arm and a secondary arm for defining a first coupler interior bore; said upper clamp having a primary arm and a secondary arm for defining a second coupler interior bore; said second end of said first pole disposed in said first coupler interior bore of said lower clamp; a first clamp compressor extending between said primary arm and said secondary arm of said lower clamp and applying a compressive force between said primary arm and said secondary arm for defining a lower clamp lock and coupling said slide controller with said first pole; a second clamp compressor extending between said primary arm and said secondary arm of said upper clamp and applying a compressive force between said primary arm and said secondary arm for defining an upper clamp lock and preventing slidable displacement of said second pole relative to said first pole; said second clamp compressor applying a non-compressive force between said primary arm and said secondary arm for said upper clamp defining an upper slide guide; said upper slide guide facilitating the slidable displacement of said second pole relative to said first pole; a bushing defining an internal bore and an exterior surface; said first end of said second pole disposed and coupling to said internal bore of said bushing; said exterior surface of said bushing slidably engaging with said interior bore of said first pole for defining a lower slide guide; and said lower slide guide and said upper slide guide facilitating the slidable displacement of said second pole relative to said first pole.
