Abstract

The invention discloses a set square. The set square comprises a set square body. A magnet is arranged at the backs of three angles of the set square respectively. During drawing, the set square is absorbed onto a drawing plate, so that drawing can be performed without pressing the set square by hands, and accordingly, physical strength is saved for drawing persons. The set square is simple in structure, novel in design and convenient to use.

Description

Set square
Technical field
The present invention relates to a kind of drawing instrument, especially a kind of set square.
Background technology
Set square, as a kind of traditional drawing instrument, extensive use in teaching.But the set square used in teaching is often all very large, and teacher is very inconvenient when drawing: need a hand according to set square, another hand-drawing line, and operation is gruelling like this.At present, market also there is no a kind of set square with adsorption function.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of set square, and this set square, with adsorption function, is adsorbed on during drawing on drawing board and just can carries out mapping operation, and this set square structure is simple, easy to use, saving muscle power.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of set square, comprises set square, and the back side at three angles of set square is respectively equipped with one block of magnet.
Beneficial effect:
Set square provided by the invention, is adsorbed on during drawing on drawing board, does not need to pin this set square with hand, just can carry out mapping operation, thus saves muscle power for drawing personnel.This set square structure is simple, novel in design, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Number in the figure is: 1, set square; 2-4, magnet.
Detailed description of the invention
As shown in Figure 1, the present invention includes set square 1, the back side at three angles of set square 1 is respectively equipped with one block of magnet 2,3,4.
Be adsorbed on drawing board by this set square during drawing and just can use, do not need to pin set square with hand, thus save muscle power for drawing personnel, this invention structure is simple, novel in design, easy to use.
