Abstract
The utility model relates to a line drawing device for English teaching, which comprises a rectangular framework, wherein two guide rails are respectively arranged on one pair of opposite lateral sides of the framework, two first handles are respectively arranged at the other two lateral sides of the framework, a slide block is arranged on the guide rails, a plurality of chalk-fixing clamps are arranged at the lower part of the slide block, a second handle is arranged at the upper part of the slide block, and a sucking disk which can be used for fixing the framework onto a blackboard is arranged on the framework. When the line drawing device is used, the framework is fixed onto the blackboard through the sucking disk, and then the slide block is dragged to slide on the guide rails through the second handle, so that four parallel lines can be drawn, and therefore the line drawing device has the advantages of convenience in use and time-saving and labor-saving effects.
Description
Technical field
The utility model relates to a kind of teaching aid, relates to specifically a kind of English teaching line-plotting device.
Background technology
In process of English teaching, teacher often need to draw parallel lines on blackboard, ways of writing with teach English word or sentence, present common setting-out mode is to combine by ruler or set square, then on blackboard, carries out setting-out, and parallel lines are drawn one by one, this setting-out mode once can only be drawn one, and the difficult grasp of the spacing between adjacent straight line, use inconvenience, waste time and energy.
Utility model content
Problem to be solved in the utility model is to provide a kind of easy to use, time saving and energy saving English teaching line-plotting device.
For addressing the above problem, the technical scheme that the utility model adopts is: a kind of English teaching line-plotting device, comprise the framework that is shaped as rectangle, described framework is wherein provided with guide rail on a pair of relative side, on two other side of described framework, be provided with the first in command, on described guide rail, be provided with slide block, the bottom of described slide block is provided with a plurality of chalk geometrical clamps, the top of described slide block is provided with the second in command, is provided with and framework can be fixed on to the sucker on blackboard on described framework.
A concrete prioritization scheme, is provided with clamping screw on described slide block.
A concrete prioritization scheme, the quantity of described chalk geometrical clamp is four.
A concrete prioritization scheme, is provided with chalk in described chalk geometrical clamp.
The utility model is taked above technical scheme, has the following advantages: during use, by sucker, framework is fixed on blackboard, then by the second in command, drags slide block and slide on guide rail, can draw four parallel lines, and easy to use, time saving and energy saving.
