Abstract

The invention provides a set square. The set square can be used for not only measuring an angle but also drawing a specified angle, and is rapid and sensitive. A goniometer is arranged at the end part of one side of the set square; a rotating shaft is arranged in the circle center of the goniometer; a ruler and a pointer are mounted on the rotating shaft; and a handle is arranged on the set square. Compared with the prior art, the set square provided by the invention is simple in structure and complete in function, can be used for not only measuring an angle but also drawing a specified angle, and overcomes the defect of repeated conversion among a goniometer, a ruler, a set square and other tools in a drawing process.

Description

A kind of set square
Technical field
The present invention relates to field of Education and teaching, specifically a kind of set square.
Background technology
Set square function singleness used in everyday, it is impossible to be applicable to measure angle, specified angle can be drawn again.
Summary of the invention
The invention provides a kind of set square, angle can be measured, specified angle and rapid sensitive can be drawn again.
The present invention is achieved in that the end, a limit of set square arranges angulometer, and the home position of angulometer arranges rotating shaft, and rotating shaft is installed ruler and pointer, with handles on set square.
Described ruler and pointer point-blank, can synchronize along axis of rotation.
Angulometer part on described set square is that transparent material is made.
The invention has the beneficial effects as follows: that compared with prior art there is simple in construction, multiple functional, angle can be measured, specified angle can be drawn again, it is to avoid the drawback that when being figure, the instrument such as angulometer and ruler set square switches repeatedly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure 1, angulometer, 2, rotating shaft, 3, ruler, 4, pointer, 5, set square, 6, handle.
Detailed description of the invention
It is described further below in conjunction with accompanying drawing.
As it can be seen, set square 5 end, limit arranges angulometer 1, the home position of angulometer 1 arranges rotating shaft 2, and rotating shaft 2 is installed ruler 3 and pointer 4, on set square 5 with handles 6.
When need to measure angle, the transparent angulometer 1 on available set square 5 measures；When need to draw the angle formulating angle, first stir ruler 3, make pointer 4 point to given angle, respective angles can be drawn along the sideline of ruler 3 and set square 5, it is to avoid the drawback that when being figure, the instrument such as angulometer and ruler set square switches repeatedly.
