An automatic extensible telescopic apparatus includes an internal tube inserted in an external tube. A positioning unit includes a ferrule, two fins, an axle, a toothed wheel and a first detent. The ferrule is provided on the external tube. The fins extend from the ferrule. The axle is supported on the fins. The toothed wheel is supported on the axle and includes teeth for insertion in recesses defined in the internal tube. The first detent is supported on the fins for engagement with the toothed wheel. A handle includes two leaves and a second detent. The leaves are placed between the fins and supported on the axle. The second detent is supported on the leaves for engagement with the toothed wheel. An extending unit is connected to the axle so that the extending unit rotates the toothed wheel via the axle, thus extending the internal tube from the external tube.
