Description
Technical field
The utility model relates to the technical field of teaching aid, refers more particularly to a kind of English teaching aid.
Background technology
Current teacher, when teaching English alphabet, needs on blackboard, depict four line three lattice, but the hand picture that teacher oneself is simple, the ruling drawn not too specification.Provide some instruments in prior art, first line tool of the prior art is all fairly simple, easily occurs some svelteness, the unsharp situation of other lines when setting-out.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of English teaching aid.
The utility model is realized by above technical scheme:
The utility model provides a kind of English teaching aid, this English teaching aid comprises: the ruler with slide rail, be slidedly assemblied in the sliding shoe on described slide rail, described sliding shoe is provided with handle, described sliding shoe is symmetrically fixed with supporting rod, and the length direction of the vertical described ruler of the length direction of described supporting rod, each supporting rod is provided with two holders, each holder comprises: be slidably connected with described supporting rod and can be locked in the base of desired location, is connected and holing clip for clamping chalk with described base elasticity.
Preferably, described supporting rod is provided with guide rail, described base sliding is assemblied on described guide rail, and on described base, spiral is connected with the lock screw for locking described base.
Preferably, described supporting rod is provided with multiple draw-in groove, described base is provided with the buckle matched with described draw-in groove.
Preferably, described base is connected by flexure strip elasticity with described holing clip.
The beneficial effects of the utility model are: by the elastic connection structure arranged, ensure that the contact dynamics between chalk and backboard, make it possible on blackboard, depict clearly lines, facilitate teaching.
Accompanying drawing explanation
Fig. 1 is the structural representation of the English teaching aid that the utility model embodiment provides.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is the structural representation of the English teaching aid that the utility model provides.
The utility model embodiment provides a kind of English teaching aid, this English teaching aid comprises: the ruler 10 with slide rail, be slidedly assemblied in the sliding shoe 20 on described slide rail, described sliding shoe 20 is symmetrically fixed with supporting rod 30, and the length direction of the vertical described ruler 10 of the length direction of described supporting rod 30, each supporting rod 30 is provided with two holders 31, each holder 31 comprises: be slidably connected with described supporting rod 30 and can be locked in the base 311 of desired location, is connected and holing clip 313 for clamping chalk with described base 311 elasticity.
When specifically using, chalk is clipped in respectively on four holing clips 313, and the height making chalk expose is higher than the bottom of ruler 10, ensure that when ruler 10 is placed on blackboard, chalk can and blackboard between have enough support degrees, make chalk can depict lines clearly on blackboard, concrete, described base 311 is connected by flexure strip 312 elasticity with described holing clip 313.Under the effect of flexure strip 312, make chalk that enough dynamics can be had to contact with blackboard.Avoid the chalk had to contact with blackboard, the situation not having to contact had.
After having clamped chalk, ruler 10 is pressed on blackboard, has held the rear slip sliding shoe 20 of handle 21, thus drive supporting rod 30 by sliding shoe 20, and drive chalk to move by supporting rod 30, thus depict lines on blackboard.
Concrete, before portraying, the distance between the lines that depict can also be adjusted by the position adjusting holder 31.Wherein, described supporting rod 30 is provided with guide rail, described base 311 is slidedly assemblied on described guide rail, and on described base 311, spiral is connected with the lock screw for locking described base 311.Or adopt on supporting rod 30 and be provided with multiple draw-in groove, described base 311 is provided with the buckle matched with described draw-in groove.
The beneficial effects of the utility model are: by the elastic connection structure arranged, ensure that the contact dynamics between chalk and backboard, make it possible on blackboard, depict clearly lines, facilitate teaching.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
