More Information
Summary:A telescopic rod comprises an outer tube and an inner tube for entering into and coming out of the outer tube;, by incorporating a restricting mechanism and a concave portion arranged in the inner tube, the inner tube is supported to stay at a specific position of the outer tube, and an ejector is equipped for saving the required mechanical energy in response to the retreat of the inner tube into the outer tube, and for performing the relative motion of the inner tube extending by itself out of the outer tube during the mechanical energy release period. The present invention has a simple structure, and the production cost is low enough to enhance market competitiveness. The restricting mechanism comprises a base secured to the telescopic rod, two upright portions provided on the base, a manual shaft connected between the two upright portions, a gear having a synchronous actuation relationship with the manual shaft, and plural teeth around the gear to provide concave/convex engagement with the corresponding re
