Abstract
The invention provides a kind of teaching chalk set, belong to teaching aid field.It solves the problems, such as that the chalk 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, body outside is also cased with sheath, sheath can axially be slided 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, when write finish after, sheath is slided along body axial direction towards guard leading end and chalk is blocked, now can prevent chalk dust from dropping out using sheath, guard leading end end face is the supporting surface vertical with set body axis simultaneously, therefore this chalk sleeve can be supported 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 with hand and used, but chalk dust can fall unhealthful on hand therefore existing
There is a kind of chalk sleeve for entangling 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 directed to the above-mentioned problems in the prior art, there is provided one kind can prevent chalk dust from falling
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 is inserted with chalk on described socket, it is characterised in that：Described body outside is also cased with sheath,
Described sheath can axially be slided 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 using the chalk on socket be used for write, when write finish after, by sheath along body axle
To sliding towards guard leading end and blocking chalk, now 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 described chute is close to set
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 can forward keep off edge with movable slider
It is mobile, and sheath is blocked described chalk, sheath can be also kept off along movement after, and guard trailing end is kept off along upper after being against
And expose chalk.
When therefore using, it is only necessary 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 can also be adsorbed on blackboard using magnetic patch.
In a kind of above-mentioned teaching chalk set, described sheath outside is additionally provided with Anti-slip cover.
In a kind of above-mentioned teaching chalk set, described body and sheath is plastics and is 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 using the chalk on socket be used for write, when write finish after, by sheath along body axle
To sliding towards guard leading end and blocking chalk, now 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.

Specific 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 axially can be slided towards the front end of sheath 2 and block powder along body 1
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 near the front end of body 1 and the back-end location of body 1
With front is along 14 and keeps off along 15 afterwards, sheath 2 is provided with ring slider 22, and sliding block 22 is placed in chute 13, and sliding block 22 is with after
Gear along being provided with compression spring 16 between 15, compression spring 16 can band movable slider 22 towards front along 14 movements, and sheath 2 is blocked powder
Pen 12, can also keep off along 15 movements sheath 2, and the rear end of sheath 2 is kept off along 15 after being against and is exposed chalk 12 after.Support
Face 21 is provided with magnetic patch 23.The outside of sheath 2 is additionally provided with Anti-slip cover 24.Body 1 and sheath 2 are plastics and are made.The rear end of body 1 has
