Abstract
The utility model discloses a rectilinear scale. The rectilinear scale comprises a rectilinear board (1), wherein scale marks (5) are reserved on one side of the rectilinear board (1). The rectilinear scale is characterized in that: square holes (6) are also uniformly distributed at one end inside the rectilinear board (1); an acute angled set square (2) and an isosceles set square (4) are arranged inside the rectilinear board (1); a protractor (3) is also arranged inside the rectilinear board (1); and circular holes (7) are also uniformly reserved on the other side of the rectilinear board (1). The rectilinear scale has diversified functions, can conveniently and rapidly draw circles, isosceles right angled triangles, acute angled triangles and the like, and also can measure specific angles of angels. When used in an examination, the rectilinear scale also can full-fill an answer sheet conveniently and rapidly, has high full-filling efficiency and high full-filling speed, is convenient and practical, and is easy for large-area use and popularization.
Description
Technical field
The utility model relates to a kind of technical field of study article, is specifically related to a kind of ruler.
Background technology
Present examination, in order to improve the efficient of going over examination papers, multiple-choice question adopts the mode of full-filling answering card more, if the examinee does not have mode according to the rules to carry out full-filling, machine will be discerned, even answer is correct, also can't score, directly influence examinee's achievement, simultaneously, can not reflect the situation of knowledge that the examinee grasps really.A lot of examinees are arranged when asking most the full-filling effect, have reduced full-filling speed on the contrary, like this with regard to covert shortening the time of own examination.
The Chinese patent publication number is CN201205825, the utility model specification that open day is on March 11st, 2009 discloses a kind of " making things convenient for fulfilling card ", this utility model comprises transparent card, has on the transparent card and the equirotal a plurality of square holes of answering card regulation pattern.Its advantage is: both saved the answer time, guaranteed the regional independent, complete of full-filling again, met machine-readable requirement, improved efficiency and the quality of student on the examination hall.But this utility model function is too single, mentions greatly, is placed in the writing case, take many spaces, and the full-filling effect is relatively poor, and speed is slow.
The utility model content
The purpose of this utility model is to make things convenient at existing that fulfilling card function singleness, result of use are poor, full-filling speed waits deficiency slowly, and a kind of diverse in function, good, the fireballing ruler of full-filling of result of use are provided.
The purpose of this utility model realizes by following technological means: a kind of ruler, include straight plate, and a side of straight plate is provided with graduation mark, and inboard one end of described straight plate also is evenly equipped with square hole.
The inboard of described straight plate also is provided with acute angle set square and isoceles triangle plate.
The inboard of described straight plate also is provided with protractor.
The opposite side of described straight plate also evenly is provided with circular hole.
Compared with prior art the utlity model has following tangible advantage: this ruler diverse in function, can draw easily and fast circle, isosceles right triangle, acute triangle etc. can also be measured the concrete angle at angle; When this ruler uses in examination, full-filling answering card easily and fast, efficient height, the full-filling speed of full-filling are fast, convenient and practical, are easy to large tracts of land and use and promote.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, the straight plate of 1-, 2-acute angle set square, 3-protractor, 4-isoceles triangle plate, 5-graduation mark, 6-square hole, 7-circular hole.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is described in further detail:
A kind of ruler as shown in Figure 1 includes straight plate 1, and a side of straight plate 1 is provided with graduation mark 5, and inboard one end of described straight plate 1 also is evenly equipped with square hole 6.Be provided with like this, when this ruler uses in examination, can carry out the full-filling answering card by the square hole 6 that is provided with easily and fast, because it is provided with evenly, with four answer options of A, B, C, D on the answering card all always, so efficient height, the full-filling speed of full-filling are fast, convenient and practical, are easy to large tracts of land and use popularization.
The inboard of described straight plate 1 also is provided with acute angle set square 2 and isoceles triangle plate 4.The inboard of described straight plate 1 also is provided with protractor 3.This ruler diverse in function, the shapes such as circle, isosceles right triangle, acute triangle of drawing easily and fast, convenient and practical, in addition, this ruler can also throughput hornwork 3 be measured the concrete angle at angle.
The opposite side of described straight plate 1 also evenly is provided with circular hole 7.Be provided with like this, can a circular hole 7 is fixing, nib is inserted another circular hole 7 be rotated, just can draw some simply circles.
In a word, the utility model provides a kind of diverse in function, good, the fireballing ruler of full-filling of result of use.The above; it only is a part of specific embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
Claims (4)
