As preferred: semi-circle ruler and half polygon ruler are made of frivolous transparent plastic.

As preferred: bearing is embedded with magnet.

As preferred: intermediate ruler cell edges both ends are equipped with hinge, are equipped with hinge on the inside of the ruler cell edges of two sides.

As preferred: the ruler unit of semi-circle ruler and half polygon ruler is inhaled by magnet respectively to be connected, semi-circle ruler and half polygon It is connected together between ruler by magnet suction, semi-circle ruler is connect with half polygon ruler center by bearing, and class cylindrical structure is formed Ruler.

As preferred: the ruler unit of semi-circle ruler and half polygon ruler is rotated by hinge, and the expansion of ruler unit is arranged in two Straight line, the dentalation of the two, which staggeredly splices and inhales fixed by magnet, to be determined, and forms the structure ruler of one surface curve of a face straight line.

The beneficial effects of the utility model are: the utility model uses two kinds of ruler types of semi-circle ruler and half polygon ruler, pass through Hinge connection, magnet absorption, bearing rotation, dial scale, realize single tool and quickly survey and draw, both possessed ruler, protractor The function of traditional surveying and mapping tool is also applied for plotting curves and non-flat planar survey, and it is more to avoid conventional tool quantity, alternately surveys and draws The problem of use, shortens the time for the tool that is used alternatingly, saves the cost of drawing tool, securely and reliably.Also, the utility model Compact structure, it is easy to operate, it is easy to carry.

Specific embodiment

The utility model is described further below with reference to embodiment.The explanation of following embodiments is only intended to help to manage Solve the utility model.It should be pointed out that for those skilled in the art, not departing from the utility model principle Under the premise of, several improvements and modifications can be made to this utility model, these improvement and modification also fall into the utility model In scope of protection of the claims.

The NEW TYPE OF COMPOSITE Multifunctional mapping tool is made of semi-circle ruler 1 and half polygon ruler 2.Semi-circle ruler 1 and half is polygon Shape ruler 2 is made of frivolous transparent plastic, and edge is equipped with scale.Semi-circle ruler 1 is connected with half polygon ruler, 2 center by bearing 5 It connects, bearing 5 is embedded with magnet, and bearing 5 is dismountable.Semi-circle ruler 1 is made of the ruler unit of the small sector in multiple fan-shaped removing centers, ruler Unit two sides are equipped with magnet 4, and intermediate ruler cell edges both ends are equipped with hinge 3, are equipped with hinge on the inside of the ruler cell edges of two sides Chain 3 is flexibly connected between ruler unit by the hinge 3 at edge；Half polygon ruler 2 is removed the ruler of the small sector in center by multiple triangles Unit combination, ruler unit two sides are equipped with magnet 4, and intermediate ruler cell edges both ends are equipped with hinge 3, the ruler cell edges of two sides Inside is equipped with hinge 3, is flexibly connected between ruler unit by the hinge 3 at edge.

The ruler unit of semi-circle ruler 1 and half polygon ruler 2 passes through magnet 4 respectively and inhales company, while semi-circle ruler 1 and half polygon ruler It is connected together between 2 by the suction of magnet 4, center is connected by bearing 5, forms the ruler of class cylindrical structure, as shown in Figure 1.Semicircle The ruler unit of ruler 1 and half polygon ruler 2 passes through hinge 3 respectively and carries out restricted rotational movement, and expansion is arranged in two straight lines, the item of the two Dentalation, which staggeredly splices and inhales fixed by magnet 4, to be determined, and forms the structure ruler of one surface curve of a face straight line, as shown in Figure 6.

Application method:

1. plotting curves: whole to be spliced into structure shown in Fig. 1, index finger and thumb pinch 5 both ends of bearing respectively, roll semicircle Ruler 1, round edge are rolled to last bit along curvilinear path from curve initial position and are set, and last position readings are subtracted initial reading Map out length of curve.Non-planar curve mapping, it is also possible to which the track along semi-circle ruler 1 rolls, coplanar plotting curves mode Equally.

2. doing protractor use: 5 center punctuate of bearing being directed at measurement angle vertex, using the measurement side of plane protractor Formula, graticule diameter survey and draw scale corresponding to another a line to locating tab assembly bottom edge.

3. doing ruler use: taking out bearing 5, being left part is semicircle and half polygon, and level respectively self-deploys (Fig. 4), is sawed Tooth unit of plastic is interspersed staggeredly (Fig. 6), and the complete concordant side and scale that polygon is scrabbled up are regular, carry out the survey of straight line It draws.
