Patent ID: 7086797

Claim:
A light-emitting pen with pullable cover comprising an upper portion and a lower portion; the upper portion being a control portion and the lower portion being a pen tube; the pen tube being formed by a transparent outer tube; a refill within the transparent outer tube; and a spring being at a lower end of the refill so that the refill is retained in a reduced state in the pen tube; the control portion including the sleeve, the transparent outer tube connected to the sleeve; a cover on the sleeve; a light-emitting unit in the sleeve and a lower end thereof pressing the refill; a conductive terminal in the sleeve and on the light-emitting unit; wherein a cam swing rod is pivotally installed within a top of the sleeve; one side of the cam swing rod is a cam and another side thereof is a hook plate; an inner wall of the cover is installed with an upper block and a lower end thereof is a lower block; the upper and lower blocks are on the upper and lower sides of the hook plate; a bottom end of the conductive terminal is installed with a conductive reed; the conductive reed resists against a top of the light-emitting unit and is in contact with a battery electrode at a top thereof; by the expansion of the conductive reed, the conductive terminal has a gap from a top of the light-emitting unit; and a casing top of the light-emitting unit receives a light-emitting body and has a long conductive pin extended from the light-emitting body; the long conductive pin is not in contact with the battery electrode; a short conductive pin of the light-emitting body is directly in contact to another battery electrode.
