Description
Technical field
The utility model relates to a kind of English-teaching aid, especially relates to a kind of adjustable scriber for English drawing.
Background technology
Present school is in English teaching, for instruction student is to the correct of English letter or word and specification writing, English teacher usually needs on blackboard, draw four line three lattice and carries out guidance demonstration, but need English teacher to adopt ruler and chalk to draw single line one by one to complete the drafting of four rulings by the spacing measured when writing on the blackboard, the mode of this wall scroll line speed of not only ruling is slow, efficiency is low, lose time, and spacing between single line is uneven, be difficult to reach code requirement, affect plate face attractive in appearance, have a strong impact on quality of instruction.
Authorization Notice No. CN202448601U, the Chinese patent of authorized announcement date 2012.09.26 discloses a kind of English stave scriber, and belong to English study apparatus technical field, it comprises straight plate, it is characterized in that on straight plate, be provided with four vertical telescopic arms, vertical telescopic arm front end is provided with the pen cap.Its weak point is, is rigid contact between chalk and chalk sleeve, the chalk frangibility when ruling, chalk also not easily inserts in chalk sleeve, and in addition, this scriber in use, telescopic arm and chalk are vertical, can not apply pressure well on chalk, when can cause ruling, chalk can not contact well with blackboard, easily causes lines intermittently imperfect, and shade differs, and this scriber is when will take out the chalk in chalk sleeve, need to go to pull out with hand, very inconvenient.
Utility model content
The utility model is the scriber for English drawing chalk frangibility when ruling in order to solve prior art, the lines obtained are intermittently imperfect, and shade differs, and the problem that the plug of chalk is very inconvenient, provide a kind of structure simple, easy to use, chalk plug easily, chalk not frangibility during line, and the lines obtained are complete, the adjustable scriber for English drawing that shade is consistent.
To achieve these goals, the utility model is by the following technical solutions:
A kind of adjustable scriber for English drawing, comprise substrate, be fixed on the side plate of substrate both sides, adjust screw rod and lever, described substrate is equidistantly arranged at intervals with four through holes, the chalk sleeve that bottom is uncovered is all fixed with in described through hole, described adjustment screw rod passes chalk sleeve top and is threaded with chalk sleeve, the length of adjustment screw rod is greater than the length of chalk sleeve, the top of adjustment screw rod is fixed with swivel head, the bottom of adjustment screw rod is fixed with pressure head, described pressure head and chalk sleeve inwall matched in clearance, described lever is above swivel head and be fixed between side plate.Substrate of the present utility model is fixed with four chalk sleeves, therefore the utility model disposablely can complete the drafting of four rulings, line speed and efficiency improve greatly, chalk sleeve is used for grafting chalk, adjustment screw rod is threaded with chalk sleeve, by rotating swivel head, adjustment screw rod can be made to increase or decline, thus the insertion depth of adjustment chalk in chalk sleeve, make the chalk that can hold various different length in chalk sleeve, versatility is good, greatly can improve the utilization rate of chalk, easily chalk can also be ejected from chalk sleeve, make the taking-up of chalk very convenient, the utility model in use, chalk is inserted in ledge for chalk on blackboard, same level is in the end face adjusting the insertion depth of chalk in chalk sleeve and make chalk be exposed to chalk sleeve by rotating swivel head, then on blackboard, the scribe fiducials instruments such as ruler are put, hold handle, using the fiducial tool such as side plate and ruler that is positioned at bottom side in the utility model against as scribe fiducials, make chalk contact with blackboard simultaneously, finally pull lever along scribe fiducials instruments such as rulers, just disposablely four rulings can be skidded off on blackboard, in scratching process, the pressure put on chalk keeps in the same way with chalk all the time, therefore chalk can remain and to contact with blackboard in scratching process, the lines marked continuously and color uniformity, and when will take out the chalk in chalk sleeve, as long as rotate swivel head until chalk ejects by pressure head.
As preferably, described lever is in " U " shape, and it is bent into by a pipe, and the two ends of lever are fixedly connected with side plate upper surface respectively.Lever is directly bent by a pipe and forms, and easy to process, structure is simple, and comfort is good.
As preferably, the spacing between described lever and swivel head is greater than the length adjusting screw rod.
As preferably, described chalk sleeve inwall is provided with elastic layer, described pressure head and chalk sleeve inwall matched in clearance.Chalk sleeve inwall is provided with elastic layer, elastic layer is flexible compressible, is convenient to chalk and inserts in chalk sleeve, and can make to become flexible contact from rigid contact between chalk and chalk sleeve, not only make chalk not easily deviate from from chalk sleeve, and make chalk not frangibility in scratching process.
As preferably, described chalk sleeve bottom opening place is provided with interior chamfering.Interior chamfering plays the effect of guiding, is convenient to chalk and inserts in chalk sleeve.
As preferably, described swivel head is cylindric, and the face, outer circumferential of swivel head is provided with anti-slip veins.Swivel head is cylindric, and structural stability is good, and anti-slip veins, in order to improve frictional force, prevents finger from skidding when turning swivel head.
Therefore, the beneficial effects of the utility model are:
(1) disposablely can complete the drafting of four rulings, line speed and efficiency improve greatly;
(2) chalk can remain and to contact with blackboard in scratching process, and the lines marked continuously and color uniformity;
(3) structure is simple, easy to use, and chalk plug is easy, chalk not frangibility during line.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the enlarged drawing at A place in Fig. 1.
