Description
Technical field
The utility model relates to a kind of teaching aid, specifically a kind of English chalker.
Background technology
When taking lessons in English, for expressing the specification writing of letter, four lines, three lattice usually need draw on blackboard; Do not have good apparatus and draw four lines, three lattice; Usually all be teacher's drawing with a horizontal line of horizontal line of ruler; Owing to be manually-operated, not only the depth of parallelism between the horizontal line can't guarantee, and the distance between the horizontal line can not well be held; Four lines, three lattice of drawing like this are very nonstandard, can't reach the expection requirement to the expression of normalized written.
Summary of the invention
The technical assignment of the utility model is the deficiency to prior art, and a kind of English chalker reasonable in design, simple in structure is provided.
The utility model solves the technical scheme that its technical problem adopted: comprise upper bracket and lower carriage; The upper bracket that is parallel to each other and the two ends of lower carriage are connected together through connecting plate respectively; Be respectively arranged with guide slide on upper bracket and the lower carriage, be provided with clamper between the guide slide, be connected through hinge respectively between clamper two ends and the guide slide; Clamper is provided with the chalk clamping hole, and the clamper middle part is provided with push and pull bar and is connected to a fixed with it.
Vertical setting between clamper and the guide slide.
Push and pull bar is T-shaped, and the push and pull bar two ends are arranged on the guide slide top.
Vertical setting between connecting plate and upper bracket, the lower carriage.
The utility model compared with prior art, the beneficial effect that is produced is:
1), have characteristics such as reasonable in design, simple in structure, easy to use, function admirable, practicality, operate comparatively simply, use cost is low, has reduced teacher's labour intensity, guarantees that teaching carries out smoothly.
2), can draw out four lines, three lattice very easily, it is comparatively desirable to draw effect, can keep good classroom teaching efficiency, helps the raising of teaching level.
