Abstract

The utility model relates to an angle drawing apparatus, which comprises a bevel gauge, scale marks are arranged on the bevel gauge, and the bevel gauge takes semi-circle ring shape, and the bevel gauge and a ruler are connected into one body, and the bevel gauge is arranged on the upper portion of the ruler. An outward projecting half circular disc is arranged on the center of the ruler which is corresponding with the center of the bevel gauge, a guide finger is moveably connected on the half circular disc through a hinge, and a bar-shaped hole is arranged in the guide finger along the guide finger direction. When in use, the guide finger is rotated to the needed angle index, and then angle lines are drawn in a bar-shaped hole by a pencil. The angle drawing apparatus integrates a bevel gauge and a ruler, which can measure angles and can draw angles, and the angle drawing apparatus is simple, convenient and practical.

Description

A kind of angle drawing device
Technical field
The utility model relates to a kind of study stationery, relates in particular to a kind of not only energy point of view but also can draw the angle drawing device of angle.
