摘要

A method for automating the guide of two channels in a single-body ball pen, which is characterized by having inside the cylindrical body of the pen a middle partition, as a base in the coaxial sense, which presents the means of retaining and guide the mines of the same, enabling them to protrude the tips by the vertex, alternatively, under the compressive action of a double twin head carrying a tangential lever that in turn presenting a transverse projecting appendix, is enabled to select each of the holes suitable for active retention and for regression to passivity.
