Description

A kind of Multifunctional Chinese teaching chalk sleeve
Technical field
The utility model relates to a kind of Chinese teaching aid, particularly a kind of Multifunctional Chinese teaching chalk sleeve.
Background technology
At present, in the process of language teaching, teacher needs constantly lecture contents write on the blackboard with chalk, because chalk powder is easily attached to teacher on hand, is made dirty by the hand of teacher, inconvenience is brought to teacher, in addition, when the length of chalk is too short time, the chalk that teacher is difficult to grip finger is too short is write, can only give it up, thus the utilization rate of chalk is lower.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of structure simple, there is deixis and avoid chalk powder to attach to teacher's hand and the Multifunctional Chinese teaching chalk sleeve that can improve chalk utilization rate.
In order to solve the problems of the technologies described above, Multifunctional Chinese teaching chalk sleeve of the present utility model, comprise sleeve, left gripping sleeve and right gripping sleeve is provided with in described sleeve, the cross section of described left gripping sleeve and right gripping sleeve is semicircular arc, described left gripping sleeve and right gripping sleeve are oppositely arranged, described sleeve is inserted with the first pressing lever and the second pressing lever, described first pressing lever is fixedly connected with the inwall of left gripping sleeve with its inner face after right gripping sleeve through sleeve, the outer face of described first pressing lever stretches out in outside sleeve, the outer face of described first pressing lever is fixed with the first briquetting, described second pressing lever is fixedly connected with the inwall of right gripping sleeve with its inner face after left gripping sleeve through sleeve, the outer face of described second pressing lever stretches out in outside sleeve, the outer face of described second pressing lever is fixed with the second briquetting, several fastening springs are evenly equipped with between described left gripping sleeve and sleeve, also several fastening springs are evenly equipped with between described right gripping sleeve and sleeve, the diameter of inwall and the diameter of chalk of described left gripping sleeve and right gripping sleeve adapt.
In order to make chalk sleeve, there is deixis, Multifunctional Chinese teaching chalk sleeve of the present utility model, described sleeve is fixed with a laser designator, described laser designator is provided with laser lamp, battery is provided with in described laser designator, the outer wall of described laser designator is provided with a shift knob, and described laser lamp, battery and shift knob are in series.
The beneficial effect that the utility model obtains is: (1) structure is simple, (2) when teacher needs to write on blackboard with chalk time, first firmly press down the first briquetting and the second briquetting simultaneously, under the pressure effect of the first briquetting and the second briquetting, first pressing lever and the second pressing lever will drive left gripping sleeve to be separated with right gripping sleeve, now chalk is inserted between left gripping sleeve and right gripping sleeve, then the first briquetting and the second briquetting is unclamped, under the effect of fastening spring elastic force, left gripping sleeve and right gripping sleeve are drawn close gradually, and finally under the effect of the elastic force of fastening spring, chalk is clamped, teacher only need firmly grasp sleeve afterwards, just can on blackboard writing words, because the finger of teacher no longer directly contacts with chalk, thus avoid chalk powder to be attached to the hand of teacher, clean hygiene, very convenient, (3) when chalk is very short time, write by left gripping sleeve and right gripping sleeve running hand of still clamping of too short chalk can being gone forward side by side, thus can the utilization rate of raising chalk, (4) in time needing to indicate the word on blackboard, open shift knob, laser lamp will send laser and indicate, and thus has deixis.

In figure: 1, sleeve, the 2, second briquetting, the 3, second pressing lever, 4, left gripping sleeve, the 5, first briquetting, the 6, first pressing lever, 7, fastening spring, 8, right gripping sleeve, 9, laser designator, 10, shift knob, 11, laser lamp, 12, battery.
Detailed description of the invention
As depicted in figs. 1 and 2, Multifunctional Chinese teaching chalk sleeve of the present utility model, comprise sleeve 1, left gripping sleeve 4 and right gripping sleeve 8 is provided with in described sleeve 1, the cross section of described left gripping sleeve 4 and right gripping sleeve 8 is semicircular arc, described left gripping sleeve 4 and right gripping sleeve 8 are oppositely arranged, described sleeve 1 is inserted with the first pressing lever 6 and the second pressing lever 3, described first pressing lever 6 is fixedly connected with the inwall of left gripping sleeve 4 through sleeve 1 and right gripping sleeve 8 its inner face rear, the outer face of described first pressing lever 6 stretches out in outside sleeve 1, the outer face of described first pressing lever 6 is fixed with the first briquetting 5, described second pressing lever 3 is fixedly connected with the inwall of right gripping sleeve 8 through sleeve 1 and left gripping sleeve 4 its inner face rear, the outer face of described second pressing lever 3 stretches out in outside sleeve 1, the outer face of described second pressing lever 3 is fixed with the second briquetting 2, several fastening springs 7 are evenly equipped with between described left gripping sleeve 4 and sleeve 1, also several fastening springs 7 are evenly equipped with between described right gripping sleeve 8 and sleeve 1, the diameter of inwall and the diameter of chalk of described left gripping sleeve 4 and right gripping sleeve 8 adapt, described sleeve 1 is fixed with a laser designator 9, described laser designator 9 is provided with laser lamp 11, be provided with battery 12 in described laser designator 9, the outer wall of described laser designator 9 is provided with a shift knob 10, and described laser lamp 11, battery 12 and shift knob 10 are in series.
Multifunctional Chinese teaching chalk sleeve of the present utility model, structure is simple, when teacher needs to write on blackboard with chalk time, first firmly press down the first briquetting 5 and the second briquetting 2 simultaneously, under the pressure effect of the first briquetting 5 and the second briquetting 2, first pressing lever 6 and the second pressing lever 3 will drive left gripping sleeve 4 to be separated with right gripping sleeve 8, now chalk is inserted between left gripping sleeve 4 and right gripping sleeve 8, then the first briquetting 5 and the second briquetting 2 is unclamped, under the effect of fastening spring 7 elastic force, left gripping sleeve 4 and right gripping sleeve 8 are drawn close gradually, and finally under the effect of the elastic force of fastening spring 7, chalk is clamped, teacher only need firmly grasp sleeve 1 afterwards, just can on blackboard writing words, because the finger of teacher no longer directly contacts with chalk, thus avoid chalk powder to be attached to the hand of teacher, clean hygiene, very convenient.
When chalk is very short time, write by left gripping sleeve 4 and right gripping sleeve 8 running hand of still clamping of too short chalk can being gone forward side by side, thus can the utilization rate of raising chalk.
