Abstract: The present stick is comprised of first and second tubes telescopically connected together. The tubes are biased away from each other by a coaxial coil spring. A shaft is positioned within the first tube, and is biased outwardly from an outer end of the first tube by another coaxial coil spring. A cam is attached to an inner end of the shaft. Holes are arranged on the first tube adjacent the cam. Balls are positioned inside the first tube between the cam and the holes. Detents are arranged along the second tube. When the shaft is released, the balls are forced outwardly through the holes and into detents which are aligned with the holes to lock the first and second tubes together. When the shaft is depressed, the balls are retracted by the cam away from the detents and allow the first and second tubes to telescope.
