Abstract
The invention provides a kind of application method of chalk sleeve, belong to teaching aid field.The problem of chalk that it solves on existing chalk sleeve can fall chalk dust.This teaching chalk set, including body, body front end is provided with socket, and chalk is inserted with socket, sheath is also cased with the outside of body, sheath can axially slide towards guard leading end along body and block chalk, and guard leading end end face is the supporting surface vertical with set body axis, and supporting surface area is more than body cross-sectional area.Hand is held into body, it is used to write using the chalk on socket, after writing is finished, sheath is axially slided along body towards guard leading end and chalk is blocked, now it can prevent chalk dust from dropping out using sheath, while guard leading end end face is the supporting surface vertical with set body axis, therefore can be supported on this chalk sleeve on lectern with table top cooperation using supporting surface, in order to place.
Description
Technical field
The invention belongs to teaching aid technical field, it is related to a kind of teaching chalk set.
Background technology
When teacher uses chalk, generally directly held and used with hand, but chalk dust can fall unhealthful on hand therefore existing
There is a kind of chalk sleeve to be used to entangle chalk, but the chalk of chalk sleeve front end can also fall ash often, it is therefore necessary to it is improved.
The content of the invention
The purpose of the present invention is to prevent chalk dust from falling there is provided one kind for the above-mentioned problems in the prior art
Go out, and the teaching chalk set that can conveniently place.
The purpose of the present invention can be realized by following technical proposal：A kind of teaching chalk set, including body, it is described
Body front end is provided with socket, and described socket and is inserted with chalk, it is characterised in that：Sheath is also cased with the outside of described body,
Described sheath can axially slide towards guard leading end along body and block described chalk, and guard leading end end face is and body axle
The vertical supporting surface of line, described supporting surface area is more than body cross-sectional area.
Hand is held into body, you can be used to write using the chalk on socket, after writing is finished, by sheath along body axle
To being slided towards guard leading end and blocking chalk, now it can prevent chalk dust from dropping out using sheath, while guard leading end end face is
The supporting surface vertical with set body axis, therefore this chalk sleeve can be supported on lectern with table top cooperation using supporting surface, with
It is easy to place.
In a kind of above-mentioned teaching chalk set, described body outer wall is provided with chute, and the described close set of chute
Body front end and body back-end location have front edge and rear gear edge respectively, and described sheath is provided with ring slider, described sliding block
It is placed in chute, and sliding block and rear gear are provided with compression spring between, described compression spring energy band movable slider keeps off edge forward
It is mobile, and sheath is blocked described chalk, sheath can be also kept off after along moving, and guard trailing end is kept off after being against along upper
And expose chalk.
Therefore in use, only needing to slide sheath towards body rear end, expose chalk, after finishing, loose one's grip
Chalk is protected, it is to avoid chalk dust is dropped out.
In a kind of above-mentioned teaching chalk set, described supporting surface is provided with magnetic patch.
Therefore it can also be adsorbed using magnetic patch on blackboard.
In a kind of above-mentioned teaching chalk set, Anti-slip cover is additionally provided with the outside of described sheath.
In a kind of above-mentioned teaching chalk set, described body and sheath is that plastics are made.
In a kind of above-mentioned teaching chalk set, described body rear end has smooth, spherical face.
Compared with prior art, the invention has the advantages that：
Hand is held into body, you can be used to write using the chalk on socket, after writing is finished, by sheath along the axial court of body
Guard leading end slides and blocks chalk, now can prevent chalk dust from dropping out using sheath, while guard leading end end face is and set
The vertical supporting surface of body axis, therefore this chalk sleeve can be supported on lectern with table top cooperation using supporting surface, in order to
Place.

Embodiment
The following is specific embodiment of the invention and with reference to accompanying drawing, technical scheme is further described,
But the present invention is not limited to these embodiments.
As shown in figure 1, a kind of teaching chalk set of the invention, including body 1, the front end of body 1 is provided with socket 11, and socket
Chalk 12 is inserted with 11, the outside of body 1 is also cased with sheath 2, and sheath 2 can axially slide towards the front end of sheath 2 along body 1 and block powder
Pen 12, and the front end surface of sheath 2 is the supporting surface 21 vertical with the axis of body 1, the area of supporting surface 21 is more than the cross section face of body 1
Product.
Further, the outer wall of body 1 is provided with chute 13, and chute 13 is distinguished close to the front end of body 1 and the back-end location of body 1
With front along 14 and rear gear along 15, sheath 2 is provided with ring slider 22, and sliding block 22 is placed in chute 13, and sliding block 22 is with after
