Method and system of a quick-connector assembly
View Patent ↗Quick connector assembly. At least some of the illustrative embodiments involve coupling an implement that has a stem member to the distal end of a pole that defines a long axis. The coupling comprising: inserting the stem member that defines a cross-sectional shape into an exposed aperture of a connector where the exposed aperture defines a cross-sectional shape that corresponds to the cross-sectional shape of the stem member; and then locking the implement into the connector such that the both rotational movement of the implement, and movement parallel to the long axis, is restrained, the locking by turning a cam member associated with the connector less than a full rotation.
