Abstract:

Quick release lock mechanisms for releasably connecting an extension pole to a tool handle include an adaptor attached to an end of the extension pole having a smooth cylindrical outer end portion axially slidable into and out of an internally threaded bore in the tool handle. A bearing support is provided for the cylindrical outer end portion when fully inserted into the bore. Also, a non-rotatable connection is provided between the adaptor and tool handle when the cylindrical outer end portion is fully inserted into the bore to prevent relative rotation therebetween, and a releasable latch prevents the cylindrical outer end portion from being withdrawn from the bore unless released.
