Claim:
A multi-purpose pen comprising an upper pen shaft, a lower pen shaft, a cone-shaped lucent section, a hollow middle ring and a pen clamp; and the characteristics thereof being that: the upper pen shaft and the lower pen shaft are joined by the hollow middle ring in between; the cone-shaped lucent section faces an outward direction on a rear end of the upper pen shaft such that light beams emitted from 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; and between the circuit board and the protruding object is an insulating strap for preventing electrical leakage between the circuit board and the protruding object; wherein the cone-shaped lucent section is configured to provide a tip surface for contacting a touch panel screen without scratching the screen.
