Description
Technical field
The utility model relates to the key chain of band laser head.
Background technology
In conventional teaching, in order to the knowledge on Students ' Learning blackboard can accurately be guided, usually adopt religion rod to guide, but religion rod does not have retractility, therefore, carries inconvenience very.Then there is telescopic religion rod afterwards, but use or inconvenience, therefore, the present laser aid occurred with laser guidance, although this special laser aid is easy to use a lot, but need often to carry in teaching process, and if leave behind, then give teaching just brings inconvenience.
Summary of the invention
In order to prevent leaving behind laser teaching aid, and be easy to carry, the utility model provides a kind of key chain with teaching laser head.
For achieving the above object, a kind of key chain with laser head, comprises clip and movable button, and movable button is hinged on clip, between clip and movable button, be provided with spring; Connector is provided with in the lower end of clip, connector is provided with cavity, the inwall of cavity is provided with internal thread, in cavity, be threaded connection insulating cylinder body, and cavity is stretched out in the lower end of insulating cylinder body, conduction cylindrical shell is provided with in insulating cylinder body, be provided with battery core in conduction cylindrical shell, a pole of battery core is electrically connected with conduction cylindrical shell, has been embedded in laser head at metal cylinder, one pole of laser head is corresponding with another position, pole of battery core, and another pole of laser head is connected with conduction cylindrical shell; Back-moving spring is provided with between laser head and battery core; Metal cylinder is provided with LED installing hole relative to the other end of laser head, is provided with LED light source in installing hole, LED light source and laser head use same battery core.Connector has been threaded connection adapter sleeve, and adapter sleeve is provided with key-ring.
The beneficial effects of the utility model are: in order to can inlet/outlet smoothly, key chain is carried with, therefore, laser head and LED illumination lamp are set in key chain, can prevent from leaving behind laser teaching aid and illuminations, be provided with laser head at the two ends of cylindrical shell and LED illumination lamp is also easy to carry.When not needing to use laser head, adapter sleeve being connected on connector, being convenient on the one hand hang key, the effect of protection laser head can be played on the other hand; When needs use laser head, screwed down from connector by adapter sleeve, the elastic force that pressing laser head makes laser head overcome back-moving spring impels a pole of laser head and another pole of battery core to be electrically connected, thus reaches the object of laser head luminescence, therefore, use very convenient.
