Abstract

The utility model discloses a line drawing device for English writing. The line drawing device for English writing comprises a pulling wire box and a pulling wire buckle fixing device. A rolling shaft is movably arranged in the pulling wire box. The rolling shat penetrates through a box body of the pulling wire box. The two shaft ends of the rolling shaft are clamped on the pulling wire box through rotary knobs. Four winding shafts are evenly arranged on the rolling shaft. A pulling wire is wound around each winding shaft. The wire end of each pulling wire is fixed to a corresponding pulling wire buckle. The pulling wire buckle fixing device corresponding to the pulling wire box is provided with a buckle groove. The pulling wire buckles are clamped in the buckle groove. The line drawing device for English writing is small in size, and capable of being conveniently installed on the two sides of a blackboard. A user can draw lines manually or pluck the wires according to needs, so that four lines and three-rows are automatically formed on the blackboard, in this way, the situation that due to the fact that inclined four lines and three-rows are drawn, the teaching quality is influenced is avoided, the interest in writing on the blackboard of a teacher and the teaching quality are improved, and the learning efficiency of students is improved.

Description

English writing scriber

Technical field

The utility model relates to a kind of English writing scriber, belongs to English teaching field.

Background technology

In the teaching process of English, be unable to do without writing on the blackboard, especially the explanation of the explanation of English word and letter, phonetic symbol etc. often needs four line three lattice to assist explanation in explanation process, could separate so the correct literary style of clear explanation about English word, letter and phonetic symbol.

At present, most teacher is by with chalk Freehandhand-drawing four line three lattice, still due to the length of blackboard and individual's writing on the blackboard custom, also often occurs four line three lattice pictures partially to draw oblique situation, to such an extent as to affects quality of instruction.

Utility model content

The purpose of this utility model is to provide a kind of conveniently English writing scriber of Freehandhand-drawing four line three lattice in teaching board.

In order to address the above problem, the technical solution adopted in the utility model is: a kind of English writing scriber, comprise that line box and bracing wire buckle fixture, in described terminal box, be movably set with an axis of rolling, the described axis of rolling runs through the box body of terminal box, and the axle two ends of the axis of rolling are stuck on terminal box by knob; On the described axis of rolling, be evenly provided with four rolls, on described four rolls, be wound with respectively bracing wire, the end of a thread of bracing wire is worn the aperture arranging on connection box and is linked and be connected together with bracing wire respectively; The bracing wire of setting corresponding to line box is buckled in fixture and is provided with buckle slot, and described bracing wire button is stuck in buckle slot; The middle part of the described axis of rolling is by the fixing online box of a spring.

Two side positions of blackboard are buckled fixture and are separately positioned in described line box and bracing wire, because its volume is light and handy, can not take very large space, thereby also can not affect writing on the blackboard.Serve as a teacher and need to use when drawing lattice device, as long as pull bracing wire button, the axis of rolling just starts to rotate thereupon, bracing wire button is stuck in buckle slot, has so just formed four line three lattice, teacher can draw four neat line three lattice along four line three lattice that form on blackboard with chalk, in the time of no, as long as bracing wire button is extracted in buckle slot, bracing wire button will automatically be retracted in line box under the effect of spring, very convenient.

As further improvement of the utility model, described bracing wire is elastic cotton rope, elastic bracing wire can so that bullet draw.

As further improvement of the utility model, in described line box, chalk dust is housed, serve as a teacher when not wanting with hand-drawing line, can pull bracing wire, on blackboard, eject a line, save the trouble of setting-out.

As further improvement of the utility model, in described line box, chalk liquid is also housed, chalk liquid not only dustless environment protecting and also writing effect good, do not serve as a teacher when thinking hand-drawing line and can pull bracing wire automatic spring lines on blackboard, easy to use.

The beneficial effects of the utility model are: of the present utility model stroke of lattice device, volume is light and handy, can be arranged on easily the both sides of blackboard, forms four line three lattice.User can be as required, selects to draw by hand, or by springing bracing wire, self-act travel four line three lattice on blackboard, so just can avoid that four line three lattice are drawn to askew picture oblique, to such an extent as to affect quality of instruction, improve interest and the quality of instruction of class-teaching of teacher writing on the blackboard.Also improved student's learning efficiency.

Accompanying drawing explanation

Fig. 1 is the structural representation that the utility model is used;

In figure: 1, line box; 2, the axis of rolling; 3, knob; 4, roll; 5, bracing wire button, 6, bracing wire, 7, bracing wire button fixture, 8, buckle slot, 9, spring, 10, blackboard.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, a kind of English writing scriber, comprises that line box 1 and bracing wire buckle fixture 7, is movably set with an axis of rolling 2 in described terminal box 1, the described axis of rolling 2 runs through the box body of terminal box 1, and the axle two ends of the axis of rolling 2 are stuck on terminal box 1 by knob 3; On the described axis of rolling 2, be evenly provided with four rolls 4, on described four rolls 4, be wound with respectively bracing wire 6, the end of a thread of bracing wire 6 is worn the aperture arranging on connection box 1 and is linked together with bracing wire button 5 respectively; The bracing wire of setting corresponding to line box 1 is buckled fixture 7 and is provided with buckle slot 8, and described bracing wire button 5 is stuck in buckle slot 8; The middle part of the described axis of rolling 2 is by the fixing online box 1 of a spring 9.

In use, line box 1 and bracing wire are buckled to fixture 7 and be separately positioned on two side positions of blackboard 10, because its volume is light and handy, can not take very large space, thereby affect writing on the blackboard.Serve as a teacher and need to use when drawing lattice device, as long as pull bracing wire button 5, the axis of rolling 2 just starts to rotate thereupon, bracing wire button 5 is stuck in buckle slot 8, has so just formed four line three lattice, teacher can draw four neat line three lattice along four line three lattice that form on blackboard 10 with chalk, in the time of no, as long as bracing wire button 5 is extracted in buckle slot 8, bracing wire button 5 will automatically be retracted in line box 1 under the effect of spring, very convenient.

Described bracing wire 6 is elastic cotton rope, elastic bracing wire 6 can so that bullet draw.

In described line box 1, chalk dust is housed, in described line box 1, chalk dust is housed, serve as a teacher when not wanting with hand-drawing line, can pull bracing wire 6, on blackboard 10, eject a line, save the trouble of setting-out.

In described line box 1, chalk liquid is also housed, chalk liquid not only dustless environment protecting and also writing effect good, serve as a teacher when thinking hand-drawing line and can pull bracing wire 6 automatic spring lines on blackboard 10, easy to use.

Of the present utility model stroke of lattice device, volume is light and handy, can be arranged on easily the both sides of blackboard, forms four line three lattice.User can be as required, selects to draw by hand, or by springing bracing wire, self-act travel four line three lattice on blackboard, so just can avoid that four line three lattice are drawn to askew picture oblique, to such an extent as to affect quality of instruction, improve interest and the quality of instruction of class-teaching of teacher writing on the blackboard.Also improved student's learning efficiency.
