In the technical solution described above, it is preferable that a plurality of scale lines are provided on both sides of the arcuate slide groove, and the positioning slide is provided with an indicator plate which can coincide with any one of the scale lines. Corresponding angle values are arranged on the scale lines.

In the technical solution described above, it is preferred that the positioning pin is screwed to the positioning slide. With this setting, the positioning pin can be attached to the positioning slide for positioning, or it can be detached and installed on the drawing triangle body so that it cannot be easily lost, and it can also be detached as a scoring tool.

In the technical solution described above, it is preferable that a first through hole is provided in the drawing triangle body, wherein the positioning pin can be screwed to the drawing triangle body on one side of the first through hole. With this setting, the positioning pen can be hidden in the drawing triangle body so that it does not interfere with operation at a time of use.

In the technical solution described above, it is preferred that the support plate is provided with a second through hole which communicates with the first through hole, wherein the positioning pin can extend from the second through hole to the first through hole and is connected to the drawing triangle body is.

In the technical solution described above, it is preferred that a straight ruler is hinged to the drawing triangle body, wherein the straight ruler can be folded on the drawing triangle body. The foldable straight ruler after unfolding can increase the measured distance, which allows a wider range of applications.

In the technical solution described above, it is preferred that one end of the straight ruler is provided with a magnet, and after folding by the magnet on the drawing triangle Body or to a piece of iron provided in the drawing triangle body. This setting can make it easier to position the straight ruler after recording.

The advantageous effect of the present utility model is that it has a simple structure, is convenient to use to draw angular lines of any angle, and the corresponding accessories are conveniently worn and not lost; wherein a straight ruler section is also provided, which is foldable and fixable, whereby the measuring distance is increased and there is a wider applicability.
