Walking stick having multiple functions

Abstract

A walking stick includes a shank, a handle, a housing, and a control circuit device. The control circuit device includes a circuit board, a gear unit, a rocker lever, a generating motor, a storage battery, a lighting circuit, a warning circuit, a sounding circuit, and a charging circuit. Thus, the walking stick can provide an illuminating effect, a video warning effect, an audio warning effect and a recharging function. In addition, the user only needs to swivel the rocker lever to drive the generating motor to generate an electric power which is stored in the storage battery unit, so that the walking stick can generate an electric power manually without having to replace any battery, thereby facilitating the user operating the walking stick outdoors.
