Abstract
A multi-purpose convenient protractor comprises a rectangular main body with angular scales integer multiples of 0 and 5 in the range of 180 DEG, wherein each angle has a small mark via-hole, and length scales are formed on the two sides. The multi-purpose convenient protractor has convenient use, and can be used for constructing arbitrary angles. Additionally, the multi-purpose convenient protractor also has the functions of a straight ruler and a set square to achieve three purposes.
Description
Technical field
A kind of drawing appliance that angle is used, genus stationery class of drawing.
Background technology
Present protractor is semi-circular, on the graduation mark of 0 and 5 integral multiple angle is arranged in 180 angular ranges.Earlier reserve angle with protractor when drawing angle, draw with ruler or set square comparison, this method is very inconvenient.More difficult pictures is accurate when drawing 5 non-integral multiple angle, and it is difficult that primary and secondary students especially feel.
Summary of the invention
The purpose of this utility model provides a kind of multipurpose convenience type protractor, accomplishes that directly picture is arbitrarily angled, easy to use, one-object-many-purposes.
The utility model main body is a rectangle, and the graduation mark of the integral multiple angle of 180 angular ranges interior 0 and 5 is arranged on it, and each angle all has corresponding sign small through hole, on two limits the length groove is arranged.
Compared with the prior art, characteristics of the present utility model are to use very convenient, can draw arbitrarily angled.If need a certain angle of picture, the sign small through hole that only needs nib to be aimed at this angle is drawn point, should get final product with the initial point line by point then.In addition, also have the function of ruler and set square concurrently, a thing three usefulness.
Description of drawings
Fig. 1 is a multipurpose convenience type angle gage structure schematic diagram
The specific embodiment
As shown in the figure, main body 1 is a rectangle, and the graduation mark of the integral multiple angle of 180 angular ranges interior 0 and 5 is arranged on it, and each angle all has on corresponding 2, two limits of sign small through hole the length groove is arranged.
Claims (1)
1, a kind of multipurpose convenience type protractor is characterized in that main body (1) is a rectangle, and the graduation mark of the integral multiple angle of 180 angular ranges interior 0 and 5 is arranged on it, and each angle all has corresponding sign small through hole (2), on two limits the length groove is arranged.
