Description

Triangular ruler that can hold a pen

【Technical field】

The utility model relates to a triangular ruler capable of accommodating pens, which belongs to the field of stationery.

【Background technique】

At present, there is no ruler with multiple markings on the market, and there is no combination of a pen embedded in the ruler, and the existing multi-purpose ruler is only a combination of a set square and a protractor.

【Content of utility model】

The technical problem to be solved and the technical task proposed by the utility model are to overcome the defects of the prior art and provide a triangular ruler which can accommodate a pen by setting a pen in the middle of the triangular ruler. For this reason, the utility model adopts following technical scheme:

The triangular ruler capable of accommodating pens is characterized in that a cylindrical accommodation cavity is opened in the triangular ruler, a dovetail groove is provided at the opening of the accommodation cavity, a pen matching the diameter of the accommodation cavity is provided in the accommodation cavity, and a pen tip is provided There is a connection part that matches the dovetail groove. Utilizing the characteristic of the large space of the triangular ruler body, the pen is arranged in the ruler body, which is easy to carry and use.

The three rectangular planes of the triangular ruler are respectively provided with centimeter scales, inch scales and angle scales, and the side with angle scales is also provided with market inch scales. The scales of various standards coexist, which is convenient for selection, conversion and use.

The angle scale is provided with a 90-degree marking line, and the market-inch scale is provided with a marking line corresponding to the 90-degree marking line. Put the triangular ruler on a straight line so that the marking line corresponds to an original point, and then select the required scale in the angle scale according to the needs, and then click a positioning point, and then connect the original point with the positioning point to draw The desired angle formed by straight lines and connecting lines. In the same way, the angle between two straight lines can also be measured sideways by this method, so that the triangular ruler has the function of a protractor.

The utility model has a reasonable structure, integrates different measuring length units and measuring angle units together, uses a ruler to express, and embeds the pen in the ruler, realizes the combination of the pen and the ruler, saves space, and is easy to carry and use It's all very convenient.
