Abstract

The utility model relates to a ruler which comprises a ruler. The surface of the ruler is provided with a semicircular gap, the surface of the gap arc segment is sequentially marked with angle scales from '0'to '180', the middle point of the gap straight-line segment is movably connected with a range pole, and the top end of the range pole is beyond the arc segment. The other side of the ruler is processed into a pectinate structure. The ruler has the advantages of simple structure, comprehensive functions, convenience, practicality, reasonable process and the like.

Description

A kind of ruler

Technical field the utility model relates to a kind of study article, especially a kind of drawing, survey tool.

Background technology is well-known, and ruler is measurement and a drawing instrument the most frequently used in people's study and work.Yet present ruler kind is a lot, and ruler, angle square, "T"-shaped chi or the like are arranged, but does not but have a kind of ruler can possess multiple function, and also therefore people need constantly to change the ruler kind in study and work, very trouble.

The summary of the invention the purpose of this utility model provides a kind of multi-purpose tool of measuring straight line, angle, particularly a kind of ruler.

The utility model mainly comprises ruler, offers semicircle gap on the ruler surface, to " 180 " marking angle index in turn, flexibly connect mark post in gap straightway midpoint along gap arc surface from " 0 ", and the mark post top surpasses arc; Be processed into broach shape structure along the ruler opposite side.

During use, the user can normally utilize ruler to draw or measure straight line; When angle measurement was spent, the user was pressed in semicircle gap straight line and treats angle measurement one side, rotates mark post then, pushes down another side with mark post, in semicircle gap camber line limit viewing angle, just can measure the angle for the treatment of angle measurement at last; In addition, the user also can utilize the chi face of broach shape to come combing hair, performance comb effect.

Compared with the prior art, the beneficial effects of the utility model are: simple in structure, complete function, convenient and practical, technology is reasonable, possesses the function of protractor, ruler, comb, satisfies people's different needs.

Description of drawings Fig. 1 is a stereochemical structure sketch of the present utility model.

The specific embodiment is in stereochemical structure sketch of the present utility model shown in Figure 1, mainly comprise ruler 1, offer semicircle gap on ruler 1 surface, along gap arc surface from " 0 " to " 180 " marking angle index 2 in turn, flexibly connect mark post 3 in gap straightway midpoint, and mark post 3 tops surpass arc; Be processed into broach shape structure along ruler 1 opposite side.

Claims (1)
