Description

A kind of light pen

Technical field:

The utility model relates to the stationery technical field, refers in particular to a kind of light pen.

Background technology:

Light pen is a kind of product that can make pen produce light by the light-emitting device that is provided with in the pen, and it strengthens the aesthetic feeling of pen by the light that self produces, thereby brings the visual enjoyment of a kind of U.S. of user.But at present the control device of light pen is comparatively complicated, and it is provided with two control device usually, and one is used to control extinguishing or lighting of light emitting diode in the light pen, and another is used to control stretching out of pen core or withdraws.Adopt the not only feasible internal mechanism complexity of this control device, and also inconvenience of operation.

On the other hand, in order to satisfy people's demand, a tool manufacturer has made an a kind of tool that has a plurality of different colours pen cores.People can select the pen core of different colours to write in use as required like this.It realizes this purpose by a rotation extending apparatus, and its inside comprises at least two protruded tubes, and the end of each protruded tube is the pen core of fixedly connected different colours all.Make the movement of rotation extending apparatus and the rotation that fixed cover produces certain angle during use, drive one of them protruded tube and outside device, stretch out, stretch out the shaft of a writing brush, make the user to write thereby drive the pen core that is attached thereto.When needs conversion pen core, reverse rotation, the then current pen core that is just using is retraction under the protruded tube that is attached thereto drives, and another protruded tube stretches out, and the pen core that promotes another color simultaneously stretches out, realize the different colours pen core alternately.This case utilizes this revolving alternately extending apparatus to be used as the control device of light pen just.

Summary of the invention:

The purpose of this utility model is to provide a kind of folding and flexible two kinds of control device of pen core with light source to gather light pen in one.

The utility model is achieved by the following technical solution: it comprise by last pipe, down the penholder that constitutes of pipe, middle pipe, will go up pipe, down pipe, middle pipe couple together in connect tooth, be positioned at the pen core assembly and the rotating mechanism of penholder, wherein the pen core assembly comprises the battery pipe of a placement battery, the pen core that is positioned at the light emitting diode of battery pipe and is fixed on battery pipe end; With in connect in the fixing rotating mechanism of tooth and establish two protruded tubes that stretch out by left-right rotation, this protruded tube points to an electrode of battery, and have at least a protruded tube to adopt metal catheter, two electrodes of light emitting diode are connected to an electrode of battery respectively and adopt on the protruded tube of metal catheter making.

After adopting this structure, when Guan Yuzhong in the relative rotation managed, rotating mechanism was touched, stretch out thereby promote its inner protruded tube, this protruded tube will promote battery on the other side, produce certain displacement thereby promote whole pen core assembly, pen core is stretched out, realized the function of refill expansion.In addition, because protruded tube has at least one to adopt conductive material to make, when this protruded tube that adopts conductive material to make supported to the electrode at battery, the circuit of light emitting diode was connected, and light emitting diode is lighted, otherwise then light emitting diode extinguishes.
