Description
Technical field
The utility model belongs to teaching aid field and in particular to a kind of English teaching chalker.
Background technology
In English teaching, especially in the teaching process of word and phonetic symbol, instructors are needed to draw English four line lattice, ability
The more specification that word and phonetic symbol are write, but light relies on feel and eyes to be difficult to draw four line lattice being parallel to each other, once
It is lack of standardization that four line lattice are drawn, and may result in the letter that teacher writes and phonetic symbol deformation, this deformation still not unsightly, but also
Can cause to obscure it is impossible to understand the regular literary style of word and phonetic symbol to students.
Utility model content
In order to solve the problems referred to above of prior art presence, the utility model provides a kind of English teaching chalker.
The technical scheme that the utility model is adopted is:
A kind of English teaching chalker, is to be made up of two cross bars, two vertical poles and mobile scribe structure, described two
Individual cross bar is fixed between two vertical poles, and through mobile scribe structure and mobile scribe structure can be in two horizontal strokes for two cross bars
Slide on bar, described mobile scribe structure is to be made up of sliding bar, chalk fixed structure and handle, two cross bars pass through and slide
Perforation on bar, chalk fixed structure is fixed on sliding bar at equal intervals, shakes hands to be individually fixed in for u-shaped structure, its two ends
The two ends of sliding bar.
As further improvement of the utility model, described chalk fixed structure is by fixed block, push rod, nut and powder
Pen cap pipe is constituted, and described fixed block bolt is fixed on sliding bar, and chalk sleeve passes through and be fixed on fixed block, push rod interior
Portion has been threaded connection the threaded rod matching with nut, and the afterbody of threaded rod is located in chalk sleeve, under chalk sleeve
Portion is provided with fixing bolt.
As further improvement of the utility model, the inner side of one of vertical pole is provided with two suckers.
The beneficial effects of the utility model are: English teaching chalker of the present utility model, simple to operate, user
Just, only device need to be placed on blackboard, pull handle, you can four lines being parallel to each other are drawn on blackboard, and device is whole
Body Stability Analysis of Structures, chalk stationarity is also preferable, brings great convenience to the teaching of teacher, improves the teaching effect on classroom
Rate.
