Description

Lamp pen

Technical field

The utility model relates to a kind of writing implement, especially a kind of novel pen with illumination functions.

Background technology

As everyone knows, pen is a most important writing implement in people's life and work.But the function of pen does not change at present, still can only provide writing function, can't satisfy more demands of people.For this reason, we provide a kind of lamp pen to solve the difficult problem that no luminous environment can't use pen.

Summary of the invention

The purpose of this utility model provides a kind of lamp pen, is used to solve the problem that conventional pen can't be thrown light on.

For achieving the above object, the utility model lamp pen comprises nib, penholder and the cap for brush, in the penholder tip designs is internal thread hollow cannula structure, the intubate inner bottom surface is fixed two metal contacts, the inner battery of installing of penholder, and battery plus-negative plate lead respectively connects different metal contacts; Intubate is threaded with the cylinder lampshade, and the lampshade bottom surface is provided with two metal contacts, and this contact is connected with the bulb lead, and bulb is installed in the lampshade top.

After adopting said structure, the user can normally use written writing words; Under not having luminous environment night, the user can be rotated down the cylinder lampshade, when the corresponding contact of metal contact in the metal contact of lampshade bottom surface and the penholder top intubate, and the lighting circuit conducting, this moment, bulb was luminous throws light on.

The utility model has the advantages that: simple in structure, cheap, flexible operation, be widely used, illumination functions can be provided.
