Description
Technical field
This utility model relates to a kind of instructional device.
Background technology
When English teaching need on blackboard draw four line lattice, need just can be completed by assistant teaching aid, so operate cumbersome, waste time and energy, add work difficulty to teacher.Further, existing chalk holder majority is placed on dais, bring inconvenience to the use of teacher.When the chalk in chalk holder is fewer and feweri, chalk easily tilts in chalk holder, extrudes, and makes chalk fracture.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, it is provided that a kind of instructional device.
Described purpose is achieved by the following scheme:
A kind of instructional device, including framework, it is inlaid with board in described framework, longitudinally it is provided with chute on the inwall of described framework side, it is inlaid with slide block in described chute, the edge of described slide block is welded with telescopic support arm, the termination of described support arm is provided with fixed plate, described fixed plate is provided with four fixing holes, edge in described fixing hole is connected by spring arc fixture block, the edge of described framework is provided with rectangular box, the top edge of described box body is provided with gap, one end in described box body is transversely provided with groups of springs, the termination of described groups of springs is provided with push pedal, the edge of described box body is provided with placement mouth, the edge of described placement mouth has enabling by gemel connection.
Described framework is connected by hanger and body of wall are fixing.
The height of described gap is less than the height on box body top.
This utility model has the advantage that this utility model effectively saves teacher and draws the time of four line lattice.The design of box body facilitates chalk to avoid fractureing of chalk while taking, simple, practical.

Detailed description of the invention
Elaborate this utility model below in conjunction with the accompanying drawings preferred embodiment.
A kind of instructional device, including framework 1, it is inlaid with board 2 in described framework 1, longitudinally it is provided with chute 3 on the inwall of described framework 1 side, it is inlaid with slide block 4 in described chute 3, the edge of described slide block 4 is welded with telescopic support arm 5, the termination of described support arm 5 is provided with fixed plate 6, described fixed plate 6 is provided with four fixing holes 7, edge in described fixing hole 7 is connected by spring 8 arc fixture block 9, the edge of described framework 1 is provided with rectangular box 11, the top edge of described box body 11 is provided with gap 12, one end in described box body 11 is transversely provided with groups of springs 13, the termination of described groups of springs 13 is provided with push pedal 14, the edge of described box body 11 is provided with placement mouth 15, the edge of described placement mouth 15 has enabling 16 by gemel connection.The height of described gap 12 is less than the height on box body 11 top.
By coordinating of slide block 4 and chute 3, support arm 5 is risen to the upper end of board 2, chalk is inserted in fixing hole 7, makes arc fixture block 9 be stuck in fixing hole 7 by chalk by the elastic force of spring 8.Promoting fixed plate 6, make fixed plate 6 extend to the other end in one end of board 2, now, chalk draws four line lattice on board 2.With rear, support arm 5 is arranged on the lower end of framework 1, the teaching of Other subjects will not be hindered to use.
Box body 11 is fixed with framework 1 by supporting plate, one end of groups of springs 13 is fixing with the inwall of box body 11 to be connected, the other end of groups of springs 13 is fixing with push pedal 14 to be connected, by chalk by placing mouth 15 longitudinal arrangement in box body 11, making push pedal 14 be promoted forward by chalk by the elastic force of groups of springs 13, the upper end of front-seat chalk extends to the outside of gap 12.During use, take out one by one, prevent chalk from fractureing after tilting.
Present embodiment does not simply limit its protection domain to the exemplary illustrated of this patent; those skilled in the art can also carry out local to it and change; as long as no the spirit beyond this patent, all it is considered as the equivalent to this patent, all at the protection domain of this patent.
