Abstract
A hands-free system for connecting and disconnecting a tool from an adjustable length extension pole. The system includes first and second slidably interconnected elongated members, a tool-holding assembly releasably coupled to the second elongated member, and a locking assembly disposed between the first and second elongated members. The relative sliding of the first and second elongated members can be selectively restrained by rotating the first and second elongated members relative to one another. The tool-holding assembly can be disconnected from the second elongated member by sliding the first and second elongated members together.
