Abstract
The invention relates to an English teaching tool. The English teaching tool comprises a clamping body, a grip handle, a clamping chamber, a chalk clamp, a sliding groove, a connecting rod, a transverse rod, chalk sleeves, a slide way frame, slide ways and buckling clamps, wherein the clamping body is movably connected with the grip handle; the grip handle is fixedly connected with the connecting rod; the connecting rod is movably connected with the clamping body; a reset spring is arranged in the connecting position of the connecting rod and the clamping body and is connected with the connecting rod in a sleeving manner; the transverse rod is fixedly connected with the connecting rod and is fixedly connected with the chalk sleeves; the chalk clamp is connected with the clamping chamber in the sleeving manner; the sliding groove is chiseled in the inner wall of the clamping chamber in an integral molding manner; the clamping body is movably connected with the slide way frame; the slide ways are arranged on two sides of the slide way frame; the buckling clamps are rotatably connected with two ends of the slide way frame. According to the English teaching tool, a needed English writing table can be quickly drawn, time and labor are saved, a chalk head is unlikely to break, and formal standardization lines are straight to more standardize writing.
Description
Technical field
The present invention relates to a kind of study article, particularly English teaching instrument.
Background technology
In current middle and primary schools English teaching, require the writing on the blackboard of teacher on blackboard should standard attractive in appearance again, and the best scheme of the writing on the blackboard of English first finishes the scope of writing of 4 line 3 lattice, then write, all the time, teacher is with a ruler, setting-out one by one, effort of not only having taken a lot of work but also can not draw 4 line 3 lattice of codes and standards, even because setting-out holding time can not complete lesson plan, does not reach standardisation requirements.In order to address this problem, designer of the present invention has done and has studied in earnest, proposes goal of the invention of the present invention.
Summary of the invention
The present invention, mainly for above problem, provides a kind of and can draw required used in English writing form fast, time saving and energy saving chalk end not easy fracture, and simultaneously regular specification line directly allows the chalk clamp of writing specification more.Its technical scheme adopted is as follows:
English teaching instrument comprises: clamp, lever, folder chamber, chalk clamp, chute, connecting rod, cross bar, chalk sleeve, slideway shelf, slideway and clip, described clamp and lever mobile link, lever and connecting rod affixed, described connecting rod and clamp mobile link, the built-in back-moving spring of connecting rod and clamp junction, back-moving spring and connecting rod are socketed, cross bar and connecting rod affixed, cross bar is connected with chalk sleeve by affixed mode, chalk clamp is connected with folder chamber by the mode of socket, folder cavity wall is carved with chute global formation, clamp is connected with slideway shelf by the mode of mobile link, slideway shelf both sides are provided with slideway, clip is connected with slideway shelf two ends by the mode be rotationally connected.
On technique scheme basis, pulley is installed in described clip inside, and chalk clamp sidewall is provided with projection and is socketed with chute, is provided with the length that stopper slot control chalk stretches out in chute.
On technique scheme basis, be provided with anti-skidding striped in described lever, the jacket wall of chalk sleeve is provided with mobile slideway, is provided with movable base bottom chalk sleeve, and the projection of base both sides and jacket wall both sides are moved slideway and are socketed.
The present invention can draw required used in English writing form fast, time saving and energy saving chalk end not easy fracture, and regular specification line directly allows and writes specification more simultaneously.
