Description
Technical field
The utility model belongs to realia technical field, is related to a kind of improved teaching aid.
Background technology
When being imparted knowledge to students on classroom, chalk is played in daily teaching in important role, and teacher often needs to use

It is new the technical problem to be solved is that：Scribe how to be avoided to affix the dust of chalk when teacher is write.
The purpose of this utility model can be realized by following technical proposal：
A kind of improved teaching aid, the pen cap including being used for grafting chalk, one end of the pen cap offer spliced eye,
It is characterized in that, the other end of the pen cap has connecting rod, one end of the connecting rod is fixed in spherical grip part.
Its operation principle is：Before writing, first chalk is plugged in the spliced eye of the pen cap, in use, the thumb of teacher and
Index finger grasp lives the pen cap, remaining finger grip lives connecting rod and grip part, at this point, the palm of the hand leans with grip part, Neng Gouti
The stability that height is held, the palm of the hand contacts in spherical grip part, gripping get up it is pleasant, by using the teaching aid,
In writing, for the hand of teacher without being contacted directly with chalk, the hand of teacher will not affix the dust of chalk.
In a kind of above-mentioned improved teaching aid, the pen cap is cylindrical, and the connecting rod is cylindrical.In circle
The pen cap of tubular and cylindrical connecting rod can improve the comfort of gripping, and more have visual sense of beauty.
In a kind of above-mentioned improved teaching aid, opened up on the side of the pen cap there are two pressing groove, two are pressed
Indent is oppositely arranged.During writing, the thumb and forefinger of teacher can be individually positioned in corresponding pressing groove, which facilitates book
To the gripping of the pen cap when writing, and the stability of gripping can be improved.
In a kind of above-mentioned improved teaching aid, structure that the pen cap, connecting rod and grip part are integrally formed
And it is made of flexible plastic material.The integrally formed pen cap, connecting rod and grip part can be by way of injections
It processes at one time, it is easy to process, and the bonding strength between each component is higher；After teacher grips the teaching aid, by
The pen cap, connecting rod and grip part can generate slight flexible deformation, energy after stress made of flexible plastic material
It is enough to improve the comfort held.
In a kind of above-mentioned improved teaching aid, the edge at the top of the pen cap has straight chamfering, the pen cap bottom
The edge in portion has arc angling.After opening up straight chamfering, the material at the edge at the top of the pen cap is reduced, and thickness is thinning, and intensity subtracts
It is small, chalk can be made to be more prone to grafting into spliced eye；The edge of pen cap bottom has arc angling, when finger and pen cap bottom
Edge contact when, comfort can be improved.
Compared with prior art, it is as follows the advantages of the utility model：
1st, this teaching aid can improve the stability and comfort of gripping, by using the teaching aid, in writing
For the hand of teacher without being contacted directly with chalk, the hand of teacher will not affix the dust of chalk.
2nd, opened up on the side of this teaching aid field pen cap there are two pressing groove, which holds the pen cap when facilitating writing
It holds, and the stability of gripping can be improved.
