Abstract

See full text

A multi-purpose pen includes an upper pen shaft and a lower pen shaft joined by a hollow middle ring in between. The upper pen shaft has a cone-shaped lucent section at a rear end thereof, such that light beams emitted form an illumination module located in the upper pen shaft are passed out to an exterior via the cone-shaped lucent section. The upper pen shaft further has a pen clamp at the rear end thereof. A front edge of a reverse side of the pen clamp is disposed with a protruding object that is penetrated into a corresponding opening at the upper pen shaft, so as to touch-control a light source switch at a circuit board of the illumination module. An insulating strap is located between the circuit board and the protruding object for preventing electricity leakage.
