Description
Technical field
The utility model relates to the teaching auxiliary, is a kind of multifunctional chalk cover.
Background technology
Chalk is the educational aid that widely uses in the daily life, and it is mainly used in writing of blackboard literal, is conical; Its main component is a kind of sediment of white calcium sulfate, is not easy to be decomposed, and particle is bigger than dust.But this type of chalk in use often since chalk become after writing short and difficulty use and grip, for this reason, some chalk sleeves arise at the historic moment; Simultaneously, be the further function that increases chalk sleeve, this type of chalk sleeve, like the patent No. ZL200520081163.3 that discloses in the Chinese patent document, May 31 2006 Granted publication day, utility model title " Multifunction chalk sleeve "; This chalk sleeve mainly contains fixed muffle, and the screw thread rotation tube advances the screw ring, chalk holder, compositions such as laser; Through the rotary threaded rotating cylinder, make to advance the screw ring to advance, thereby reach the purpose that makes chalk stretch out.But the design of the chalk clamp structure of above-mentioned chalk sleeve is not good enough, for considering the conical structure characteristic of existing most of chalks.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of the utility model is to this area a kind of multifunctional chalk cover to be provided, and makes it solve the technical problem of existing like product structure, function singleness.Its objective is and realize through following technical scheme.
A kind of multifunctional chalk cover, body one end of this chalk sleeve is provided with laser lamp, and the external diameter of body is provided with laser button and anti-skidding line, is provided with endoporus in the body; Push laser button, the laser lamp of this chalk sleeve can use, and the endoporus of body is convenient to inserting of chalk.The other end that its structural design main points are said bodies is arranged with pen clip, and pen clip is articulated in body through clamp pin, and the clamp pin of hinged place is provided with torsion spring, and the centre bore between pen clip and the pen clip communicates with endoporus in the body.Being chalk puts into the endoporus of body through pen clip, and pen clip grasps chalk, and according to the operating position of chalk, regulates the length that chalk exposes pen clip.Thereby fix conical chalk through two independent endoporus and pen clip, endoporus is used for the placement of chalk, and pen clip is used for the clamping of chalk with fixing.
Said pen clip symmetry is " U " font notch, and the notch of pen clip and the endoporus of body are provided with the felt pad.The felt pad prevents that chalk from sliding in pen clip and endoporus; The notch of pen clip is convenient to this chalk sleeve and is fixed in apparatus such as a limit, and the clamping that is used for other article.
Be provided with PPT picture and text demonstration chip in the said body, body is provided with the picture and text button.Promptly directly control the picture and text demonstration of PPT through the picture and text button of body, PPT picture and text demonstration chip comprises parts such as wireless controller.
The utility model reasonable in design, use, easy to carry, diverse in function; Be suitable as chalk sleeve, laser religion pen or PPT picture and text demonstration program and use, ex hoc genus anne the architecture advances of product.
