Patent ID: 6926421

Claim:
A light emitting pen actuated by pivotally rotating a clip comprising an upper pen tube and a lower pen tube, the upper pen tube including a pen tube, a switch button in the pen tube, a light emitting device in the pen tube and below the switch button; and the lower pen tube including cylinder, a refill in the cylinder, a conduit resisting against a bottom of the light emitting device for receiving the refill; and a resilient spring enclosing the refill; wherein a base is at an upper end of the upper pen tube; the base has a slot; an end portion of the clip is buckled into the slot; the end portion of the clip is an eccentric block; the eccentric block is pivotally installed in the slot by using a stud; a top stud of the switch button protrudes from a central round hole of the base; a top of the top stud resists against the eccentric block of the clip; when the clip pivotally rotates upwards, the eccentric block presses the top stud so that the switch button descends to contact the light emitting device to cause a light emitting body in the light emitting device lights up; then, the light emitting device moves downwards to cause the refill to move downwards; then a pen tip of the refill protrudes out of the pen tube; when the clip pivotally rotates, the light emitting body does not light up and the tip embeds into the pen tube.
