Abstract
The invention provides a combined drawing board. A protractor and a set square of different angles are respectively arranged on a board body serving as a ruler, and hollow-out strip grooves are arranged between the protractor and the board body and between the set square and the board body. The combined drawing board has various using functions of the ruler, the set square and the protractor, and specifically, the hollow-out strip grooves can conveniently mark various measured data.
Description
Technical field
The present invention relates to a kind of drawing board, specifically a kind of combination drawing board.
Background technology
When drawing, all can use various surveying and mapping tools, particularly be unable to do without ruler, set square and these three kinds of common tools of protractor, because traditional drawing instrument all is minute other single instrument, when use and folding and unfolding, can be a great inconvenience.
Summary of the invention
The invention provides a kind of combination drawing board, ruler, set square and protractor are combined into one, use and folding and unfolding are very convenient.
The present invention includes protractor and set square on the drawing board, the technical scheme that adopts is: described drawing board is the set square that is respectively arranged with protractor and different angles at a plate body that doubles as ruler, is provided with hollow out bar groove between protractor and set square and plate body.
Beneficial effect of the present invention is: have the multiple use function of ruler, set square and protractor, particularly by hollow out bar groove, can mark easily the various data of calculating.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is structural representation of the present invention.
The specific embodiment
Shown in the accompanying drawing embodiment: drawing board is the set square 3 that is respectively arranged with protractor 2 and different angles at a plate body 1 that doubles as ruler, is provided with hollow out bar groove 4 between protractor 2 and set square 3 and plate body 1.
