Description
Technical field
The present invention relates to education and instruction technical field more particularly to a kind of chalk sleeves for being convenient for making full use of chalk.
Background technology
Chalk is instrument widely used in daily life, is generally used for being written on blackboard, and the chalk in ancient times is usually used
Natural chalk is made, but is mostly used other substance substitutions now, and the ingredient of chalk is a kind of white depositions of calcium sulfate, no
It is easily decomposed, particle is bigger than dust, and now, the chalk that the country uses mainly has two kinds of common chalk and dust-free chalk, leads
It is calcium carbonate and calcium sulfate or containing a small amount of calcium oxide to want ingredient, and the effect of chalk is exactly to write drawing in blackboard, has biography
The effect of knowledge is broadcast, to make full use of chalk and preventing chalk from polluting the finger of teacher, market has come into existence as the situation requires a kind of chalk sleeve.
However a kind of existing chalk sleeve on using there are still certain shortcoming, in use, chalk is placed in chalk
The inside tension of set, it is difficult to be moved to chalk, cause still to can not achieve and make full use of chalk, and same chalk sleeve can only
Set unification chalk, it is impossible to meet different use demands.
The content of the invention
The purpose of the present invention is to solve shortcoming in the prior art, and the one kind proposed is convenient for making full use of powder
The chalk sleeve of pen.
To achieve these goals, present invention employs following technical solutions：A kind of chalk for being convenient for making full use of chalk
Set, including the first chalk fixing pipe and connecting pole, one end of the connecting pole is screwed with the first chalk fixing pipe, first powder
The outside of fixing pipe is screwed with the first fixed frame, and first fixed frame is internally provided with the first expandable washer, the company
It connects and fixed band is fixed at the appearance wall horizontal central line position of column, the other end of the connecting pole is screwed with the second chalk and fixes
Pipe, the outside of the second chalk fixing pipe are screwed with the second fixed frame, second fixed frame to be internally provided with second swollen
Swollen washer, the both ends of the connecting pole offer chalk card slot respectively, and the inside of the chalk card slot is angularly fixed with multiple
Stay hook, the top of the stay hook are connected by resetting spring with camber sliding block, and the top of the stay hook is located at camber cunning
The one side of block is fixed with non-slip mat.
Preferably, the stay hook is designed as L-type structure.
Preferably, the outer diameter of the first chalk fixing pipe and the outer diameter of the second chalk fixing pipe are equal in magnitude.
Preferably, the outer diameter of the outer diameter and the second fixed frame of first fixed frame is equal in magnitude.
Preferably, the outer diameter of the connecting pole and the first chalk fixing pipe and the internal diameter size phase of the second chalk fixing pipe
Deng.
Preferably, the vertical center line of the connecting pole and the first chalk fixing pipe and the vertical center line of the second chalk fixing pipe
It is located along the same line.
Compared with prior art, the beneficial effects of the invention are as follows：The both ends of connecting pole are screwed with the first chalk respectively first
Fixing pipe and the second chalk fixing pipe, and the both ends of connecting pole angularly offer multiple chalk card slots, the top of chalk card slot
Portion is connected by resetting spring with camber sliding block, when chalk snap-fits into the inside of chalk card slot, inwardly squeezes camber sliding block, into
And inside pressed home spring, under the action of resetting spring, chalk is squeezed, respectively upward turn the first chalk fixing pipe and the
Two chalk fixing pipes, not only meet that chalk is movably functional, while stability when enhancing chalk engaging, secondly, even
The both ends for connecing column are screwed with the first chalk fixing pipe and the second chalk fixing pipe respectively, can meet the engaging of two chalks simultaneously,
Teacher is facilitated to write use simultaneously, expands the applicability of chalk sleeve, it is perfect that it is functional, finally, the first chalk fixing pipe
The first fixed frame and the second fixed frame are screwed with respectively with the outside of the second chalk fixing pipe, and the first fixed frame and second is fixed
The inside of frame is respectively arranged with the first expandable washer and the second expandable washer, upward the first fixed frame of turn and the second fixed frame,
So that the first expandable washer is contacted directly with the second expandable washer with chalk, chalk is squeezed, enhances the stability of end chalk,
So as to fulfill chalk is utilized to the greatest extent, economize on resources.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.
It is a kind of convenient for making full use of the chalk sleeve of chalk with reference to Fig. 1-3, including the first chalk fixing pipe 3 and connecting pole 4,
One end of connecting pole 4 is screwed with the first chalk fixing pipe 3, and the outside of the first chalk fixing pipe 3 is screwed with the first fixed frame 2, the
One fixed frame 2 is internally provided with the first expandable washer 1, and fixed band is fixed at the appearance wall horizontal central line position of connecting pole 4
