Abstract

The invention relates to a compasses and ruler combined tool, in particular to a multifunctional compasses and ruler combined tool which can be used as (a pair of) compasses, a graduation ruler and a protractor. The multifunctional compasses and ruler combined tool comprises a main graduation ruler and an auxiliary graduation ruler which are connected together through a shaft and is characterized in that the tail end of the main graduation ruler is connected with a fixing needle, the tail end of the auxiliary graduation ruler is connected with a mechanical pencil, the top end of the auxiliary graduation ruler is connected with a compasses pole, the tail end of the auxiliary graduation ruler is connected with an angle measuring ruler through a rotating shaft, and the angle measuring ruler is placed in a groove of the auxiliary graduation ruler; an eraser is mounted on the side surface of the main graduation ruler through an eraser clamping groove, an illuminating LED lamp, a switch and a button battery which are connected through wires are further mounted on the side surface of the main graduation ruler, and the button battery is mounted on the main graduation ruler through a battery clamping groove. The multifunctional compasses and ruler combined tool has the benefits as follows: the tool can be simultaneously used as the graduation ruler, the compasses and the protractor and is simple in structure, convenient to use and carry and space-saving.

Description

(1) Technical field [0001] The invention relates to a compass and ruler combination tool, in particular to a multifunctional compass and ruler combination tool which can be used as a compass, a scale and a protractor at the same time. (2) Background technology [0002] Mathematics, physics and other subjects often need to draw pictures. When drawing, it is inevitable to use tools such as scales, compasses and protractors. Under the current technology, these tools sold in the market are independent, and students need to buy them when they use them. A variety of tools not only occupy a lot of space, but also are very inconvenient to carry. Therefore, there is an urgent need for a tool that can integrate multiple functions such as a scale, a compass and a protractor, and serve the current primary and middle school students. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides a multifunctional compas...
