Abstract
A ball-point pen, characterized in that the axial advance and retraction of the tubular deposit of the ball-point pen inside its wraparound handle, is achieved by the posterior thrust of a tubular link with a large fitted head within a hemispherical bearing, or ball joint, with radial handle at its posterior pole; leaving this patella adjusted and its hand guided inside the threaded cap to the rear end of the wrapping handle, and split according to a diametral groove or guide.
