Abstract

A multipurpose plotter consists of angle-measuring and circle-drawing rule with protractor in its one end and diameter holes; scaled radius rule with radius hole array and circle center holes; circle center positioning pen and compass-rule. There is positioning linked part set in the protractor to make the plotter easy to move and take out. The constituents of the present invention may be assembled and disassembled easily and the multipurpose plotter has all the functions of set square, rule, protractor and compass. Being accurate and portable, the present invention is suitable for student and professional to use.

Description

1. Technical field [0001] The invention relates to a tool for study and work, in particular to a multipurpose plotter integrating a set square, a ruler, a protractor and a compass. 2. Background technology [0002] In study and work, rulers, compasses and protractors are commonly used measuring tools when measuring and drawing points, line segments, angles, plan views, and three-dimensional figures. These three kinds of measuring tools include at least one ruler, two set squares, one protractor, and one compass, totaling five pieces. Daily work or creative design requires round rules and more accessories, such as duckbill-shaped ink pens, extension rods, etc. These utensils also have five deficiencies in use. One is poor precision. For example, when drawing a triangle with a protractor and a ruler, the accuracy of the measuring tool is controlled by hand and personal experience, and the joints of the compass are relatively movable. Different people use the same compass to...
