Abstract
The utility model discloses an instrument is drawn to english teaching of four rulings, including the slide rail that sets up both ends about the blackboard, set up the slider that has the gyro wheel in the slide rail, gliding sliding sleeve about the cover is equipped with on the slider, be equipped with a plurality of through -hole on the sliding sleeve, be equipped with the rectangle through -hole that supplies the chalk to pass on the slider, be equipped with the pressure cap that is used for compressing tightly the interior chalk of through -hole on the sliding sleeve. The four line grids standard is drawn to this instrument, and easy operation is laborsaving.
Description
Technical field
This utility model relates to English teaching appurtenance technical field, particularly to a kind of English teaching four ruling drawing tool.
Background technology
In English teaching, teacher often often to finish four line lattice with teaching ruler on blackboard, and teacher is drawing with one one horizontal line of horizontal line of ruler when drawing four line three lattice, distance between adjacent two lines needs by experience and range estimation, the horizontal line depth of parallelism not only drawn cannot ensure, and the distance between horizontal line can not well be held, make four line three lattice drawn out nonstandard, the waste long period, and it is unfavorable for specification writing, what is more important: the existing general volume of teaching aid for drawing four line lattice is the most portable, and teaching aid weight is big, inconvenient operation.
English teaching four ruling drawing tool of the prior art, a kind of Novel English teaching equipment as disclosed in CN201410811747.5, including scriber and word plate, described word plate is arranged on bottom described scriber, described scriber includes track gauge, box body, handle and multiple sleeve, one end of described box body is connected with described handle, the uniform other end being set in parallel in described box body of multiple described sleeves, described track gauge is track box, described box body is vertically installed in inside described track gauge, and described word plate abuts with described track gauge.It is disadvantageous in that: need left hand to be pressed against on blackboard by equipment during use, right hand sliding slider, and owing to teaching equipment volume is big, operation is wasted time and energy, and the lines of picture are inconsistent, unintelligible.
Utility model content
In view of this, the purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of English teaching four ruling drawing tool, four line lattice specifications drawn by this instrument, simple to operate laborsaving.
nullFor reaching above-mentioned purpose，This utility model is by the following technical solutions: a kind of English teaching four ruling drawing tool，Including the slide rail being arranged on the upper and lower two ends of blackboard，The slide block with roller is set in described slide rail，Described slide block two ends are respectively provided with at least one roller，Sliding sleeve is provided with the pressure cap of chalk in compressing through hole，It is connected by elastic mechanism between described pressure cap and chalk，Described elastic mechanism is the spring being arranged in pressure cap，Described pressure cap is threaded connection with sliding sleeve，The sliding sleeve slided up and down it is set with on described slide block，Described sliding sleeve is provided with several through holes，Described slide block is provided with the rectangular through-hole passed for chalk，Described sliding sleeve is provided with hinged expansion link，Described slide block is provided with the fastener of expansion link clamping，Groove it is provided with in fastener，Expansion link is positioned at groove by expansion link clamping，Uniform 4 through holes on described sliding sleeve.
Described through hole longitudinal arrangement is on sliding sleeve.
Bolt on described sliding sleeve.
Compared with prior art, the beneficial effects of the utility model are: the real new tool slide of this practicality is arranged on blackboard, during use, only chalk need to be inserted sliding sleeve, being screwed on sliding sleeve by nut, chalk is pressed on blackboard by the spring in nut, by the sliding sleeve that moves right, sliding sleeve band movable slider moves right, drawing four line lattice on blackboard, four line lattice processes of drawing, without hand-held instrument, only need moving sliding sleeve, time saving and energy saving, easy to operate.Being pressed on blackboard by chalk by spring, in that context it may be convenient to the regulation pressure that is pressed on blackboard of chalk, in line drawing process, chalk is not easy to fracture, and what is more important chalk different in size all can use.Further, slided over the upper-lower position on slide block by regulation, in that context it may be convenient to four line lattice are drawn in any position on blackboard, draw four line lattice codes and standards.
