Abstract

A kind of English teaching chalker, comprise housing and scriber, housing comprises upper side band, lower sideband, left side band and the right band, scriber comprises fixation clip, sliding clamp, fixed frame and four Compress Springs, this English teaching chalker is not only simple in structure, easy to use, can on blackboard, draw out fast four line three lattice of standard, and the four line three lattice depth of parallelisms and the non-type situations of wire spacing of drawing out by ruler have been solved, improved the standardization of writing, reduce the labour intensity of teacher when teaching, improved efficiency of teaching.

Description

English teaching chalker

Technical field

The utility model belongs to teaching aid technical field, especially a kind of English teaching chalker.

Background technology

When English teaching; in order to make letter, write standard more; teacher can draw out four line three lattice conventionally on blackboard; and when drawing four line three lattice, teacher can use the drafting of a horizontal line of a horizontal line of ruler, so not only loaded down with trivial details; and the horizontal line depth of parallelism of drawing cannot guarantee; article four, also bad assurance of the distance between horizontal line, four line three lattice of drawing out are nonstandard, are unfavorable for specification writing.

Summary of the invention

The deficiency existing in order to overcome prior art, the utility model provides a kind of English teaching chalker, this English teaching chalker is not only simple in structure, easy to operate, and solved the four line three lattice depth of parallelisms and the non-type situations of wire spacing of drawing out by ruler, improved the standardization of writing.

The technical scheme that the deficiency that the utility model exists for solution prior art is taked is, comprise housing and scriber, housing comprises upper side band, lower sideband, left side band and the right band, scriber comprises fixation clip, sliding clamp, fixed frame and four Compress Springs, wherein, in housing, on upper side band and lower sideband, there is slideway, on fixed frame in scriber, there is slideway, fixed frame and fixation clip in scriber are fixed, upper side band in fixation clip two ends and housing and the slideway on lower sideband are slidably matched, sliding clamp two ends in scriber and the slideway on fixed frame are slidably matched, four Compress Springs coordinate with fixed frame and sliding clamp, on fixation clip and sliding clamp, symmetry is evenly equipped with four identical semi-circular recesses respectively.

The beneficial effects of the utility model are: this English teaching chalker is not only simple in structure, easy to use, can on blackboard, draw out fast four line three lattice of standard, and the four line three lattice depth of parallelisms and the non-type situations of wire spacing of drawing out by ruler have been solved, improved the standardization of writing, reduce the labour intensity of teacher when teaching, improved efficiency of teaching.

accompanying drawing explanation

Fig. 1 is topology view of the present utility model.

The specific embodiment

The specific embodiment of the present utility model is, with reference to Fig. 1, comprise housing and scriber, housing comprises upper side band 1, lower sideband 9, left side band 10 and the right are with 8, scriber comprises fixation clip 14, sliding clamp 3, fixed frame 2 and four Compress Springs 4, 5, 6, 7, wherein, in housing, on upper side band 1 and lower sideband 9, there is slideway, on fixed frame 2 in scriber, there is slideway, fixed frame 2 in scriber is fixed with fixation clip 11, upper side band 1 in fixation clip 11 two ends and housing and the slideway on lower sideband 9 are slidably matched, sliding clamp 3 two ends in scriber and the slideway on fixed frame 2 are slidably matched, four Compress Springs 4, 5, 6, 7 coordinate with fixed frame 2 and sliding clamp 3, on fixation clip 11 and sliding clamp 3, symmetry is evenly equipped with four identical semi-circular recesses respectively, with reference to Fig. 1, the operation principle of described English teaching chalker is, when upper class hour need be drawn out four line three lattice on blackboard, first four chalks are clamped in the fixation clip 11 and the semi-circular recesses on sliding clamp 3 in scriber, again chalker level is placed on blackboard surface, stir scriber, scriber is stirred from left to right, at this moment scriber prolongs the slideway on upper side band 1 and lower sideband 9 in housing and slides, chalk can draw out four line three lattice equably.

Claims

1. an English teaching chalker, comprise housing and scriber, housing comprises upper side band, lower sideband, left side band and the right band, scriber comprises fixation clip, sliding clamp, fixed frame and four Compress Springs, it is characterized in that: in housing, on upper side band and lower sideband, have slideway, on fixed frame in scriber, there is slideway, fixed frame and fixation clip in scriber are fixed, upper side band in fixation clip two ends and housing and the slideway on lower sideband are slidably matched, sliding clamp two ends in scriber and the slideway on fixed frame are slidably matched, four Compress Springs coordinate with fixed frame and sliding clamp, on fixation clip and sliding clamp, symmetry is evenly equipped with four identical semi-circular recesses respectively.
