Walking Stick Having Generating and Illuminating Functions

Abstract

A walking stick includes a stick body, a circuit board, a control switch, a storage battery, a generating unit, a control handle, a plurality of light emitting members, two lamp shades, a lighting unit, a buzzer, and a level detector. The light emitting members and the lighting unit can emit light beams outwardly so that the walking stick can provide a lighting function at the night or on a darker place. The control handle is pivoted relative to the stick body to drive the generating unit to generate an electric power so that the walking stick has a manually generating function without needing an external power supply. When the walking stick falls down (or the user falls down onto the ground), the buzzer is operated to emit a sound so as to provide a warning and notifying function.
