Abstract

The utility model relates to a multi-purpose ruler, on the surface of the ruler, various shapes of openings such as a roundity, a semicircle, a triangle, a squareness , a pentacle, etc are arranged, the back of the ruler is stuck with a fixing cupule; on the arc surface of the semicircle opening, angle scales are marked according to a protractor structure. When application, the user can use the ruler to draw and measure beelines normally; and can use various shapes of opening to draw various graphics; and the user can make the angle measuring through the semi-circle opening. The utility model has the advantages of rational structure, complete function, wide application, etc, a plurality of graphics can be drawn, and the ruler can be fixed randomly, and can measure angles, so as to provide the convenience to users.

Description

The multipurpose ruler

Technical field the utility model relates to a kind of drawing survey tool, especially a kind of multipurpose ruler with multiple function.

Technical background is present, and ruler is still topmost drawing survey tool.Present ruler function ratio is more single, can only draw and measure straight line, can't draw other figures, more can't measure the angle at various angles.In order to improve the problems referred to above, we provide a kind of multipurpose ruler.

The summary of the invention the purpose of this utility model provides a kind of multipurpose ruler, is used to solve the problem of common ruler function singleness.

For achieving the above object, the utility model multipurpose ruler comprises the bar plastic ruler, offers the vacancy of different shapes such as circle, semicircle, triangle, square, five-pointed star on the ruler surface; Paste fixing sucking disk at the ruler back side; At the curved surfaces of semicircle vacancy according to angle gage structure marking angle index; The triangle vacancy is compositions such as isosceles triangle, right angled triangle.

After adopting said structure, the user can just use ruler always and draw and measure straight line; Also the vacancy of available different shape is drawn various figures; In addition, the user can carry out angular surveying by semicircle vacancy, the effect of performance protractor; And the sucker that is installed in the ruler back side can arbitrarily be fixed on any plane, is convenient to user's operation.

The utility model has the advantages that: rational in infrastructure, multiple functional, be widely used, can draw multiple figure, can arbitrarily fix, and the energy measurement angle, for the user provides convenience.

Description of drawings Fig. 1 is the overall structure schematic diagram of the utility model multipurpose ruler.

The specific embodiment as shown in Figure 1, the utility model multipurpose ruler comprises bar plastic ruler 1, offers the vacancy 2 of different shapes such as circle, semicircle, triangle, square, five-pointed star on ruler 1 surface; Paste fixing sucking disk 3 at ruler 1 back side; At the curved surfaces of semicircle vacancy 2 according to angle gage structure marking angle index; The triangle vacancy is compositions such as isosceles triangle, right angled triangle.
