Description

A kind of dual-purpose teacher's pointer

Technical field

This utility model relates to a kind of teaching aid, a kind of dual-purpose teacher's pointer.

Background technology

At present, teacher is during giving lessons, it is often necessary to write lecture contents on blackboard with chalk, chalk is put down after writing, needs pick up the pointer and guide written contents to explain, and can be collected the attention of middle school student by teacher's pointer, thus improve effect of giving lessons；But teacher need during giving lessons the most hand-off in chalk and teacher's pointer, the most not only have impact on teaching efficiency, and easily make student take sb's mind off sth, have impact on effect of giving lessons, simultaneously because teacher directly becomes easily infected by chalk bits with the hand-held chalk that takes, the most unhygienic, and easily injured skin；Further, since traditional teacher's pointer the most easily blocks the font on blackboard, it is impossible to meet illumination and the requirement of projection teaching.

Utility model content

The purpose of this utility model is to provide a kind of dual-purpose teacher's pointer, with the problem solving to propose in above-mentioned background technology.

For achieving the above object, the following technical scheme of this utility model offer:

A kind of dual-purpose teacher's pointer, including chalk holder device, laser pen apparatus and auxiliary carrying device；Chalk holder device is made up of the pen cap, the first outer pen cap, the second outer pen cap, a pushing block and spring；Described pen cap left end is the most unconnected two semicircular ring chalk jacks, and jack diameter is more than chalk diameter, and left end is conformed with；The described first outer pen cap is middle hollow out cylinder, is enclosed within outside the interior pen cap, and left end is provided with the draw-in groove of spring and is provided with screw thread；Described second outer pen cap left end is provided with draw-in groove and the screwed hole of spring, and right-hand member is provided with the screw thread coordinated with laser pen shell；Described pushing block is arranged on the right-hand member of the interior pen cap, overhangs the second outer pen cap；Described spring is arranged at the draw-in groove of the first outer pen cap and the second outer pen cap；Laser pen apparatus is made up of laser pen shell, laser lamp and laser lamp switch；Described laser pen shell left end is provided with screwed hole, and right-hand member installs laser lamp；Described laser lamp switch is arranged on laser pen shell side.

As further program of the utility model: described first outer pen cap outer surface is provided with anti-slip rubber.

As further program of the utility model: auxiliary carrying device is made up of lug and Portable belt；Described lug is connected to laser pen shell side；Described Portable belt is rubber strip.

As this utility model further scheme: described laser pen apparatus built-in rechargeable battery.

Compared with prior art, the beneficial effects of the utility model are:

The feature that this utility model has reasonable in design, simple in construction, easy to use, function admirable, volume are little and easy to carry, just can write at the anti-slip rubber on the hand-held first outer pen cap of teacher on blackboard, it is to avoid finger, palm directly contact chalk；Can also use as electronic teacher pointer, facilitate teachers ' teaching, reduce the labor intensity of teacher, improve classroom teaching efficiency.

In figure: the 1-pen cap, the outer pen cap of 2-first, the outer pen cap of 3-second, 4-Portable belt, 5-lug, 6-laser pen shell, 7-laser lamp, 8-laser lamp switchs, a pushing block in 9-, 10-spring.

Detailed description of the invention

Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.

Referring to Fig. 1-4, a kind of dual-purpose teacher's pointer, including chalk holder device, laser pen apparatus and auxiliary carrying device；Chalk holder device is made up of the pen cap 1, the first outer pen cap 2, the second outer pen cap 3, a pushing block 9 and spring 10；The described pen cap 1 left end is the most unconnected two semicircular ring chalk jacks, and jack diameter is slightly larger than chalk diameter, and left end is conformed with, for being matched for clamping tightly chalk with the first outer pen cap 2；The described first outer pen cap 2 is middle hollow out cylinder, is enclosed within outside the interior pen cap 1, and left end is provided with the draw-in groove of spring 10 and is provided with screw thread, for being tightened with the second outer pen cap 3；The described second outer pen cap 3 left end is provided with draw-in groove and the screwed hole of spring 10, and right-hand member is provided with the screw thread coordinated with laser pen shell 6, and outer surface is provided with anti-slip rubber；Described pushing block 9 is arranged on the right-hand member of the interior pen cap 1, overhangs the second outer pen cap 3；Described spring 10 is arranged at the draw-in groove of the first outer pen cap 2 and the second outer pen cap 3, for ejection and the retraction of the interior pen cap 1；Laser pen apparatus is switched 8 by laser pen shell 6, laser lamp 7 and laser lamp and forms；Described laser pen shell 6 left end is provided with screwed hole, and right-hand member installs laser lamp 7；Described laser lamp 7 is used for launching laser, the content on instruction blackboard；Described laser lamp switch 8 is arranged on laser pen shell 6 side；Laser pen apparatus built-in rechargeable battery, powers for laser pen；Auxiliary carrying device is made up of lug 5 and Portable belt 4；Described lug 5 is connected to laser pen shell 6 side；Described Portable belt 4 is rubber strip.

Operation principle of the present utility model is: press interior pushing block 9, spring 10 is compressed, after the interior pen cap 1 left end stretches out the first outer pen cap 2, chalk is put in the jack of the pen cap 1, unclamping interior pushing block 9, under the elastic force effect of spring 10, the pen cap 1 returns in situ, owing to the interior pen cap 1 left end is dashed forward role, chalk is clamped；When chalk sponson is finished, pressing interior pushing block 9, chalk is released, stretches out the interior pen cap 1 under self gravitation effect, unclamps interior pushing block 9, and chalk is clamped again.

Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to make a variety of changes on the premise of without departing from this patent objective.
