ABSTRACT:
A combination measuring tool includes a main body having a first portion having a plurality of first graduations and a second portion having a plurality of second graduations, a transverse bar movably and rotatably mounted on the main body and having a semi-circular protrusion having a plurality of angle scales, a protractor secured to the transverse bar and having a plurality of angle scales, a pivot plate pivotally mounted on the protractor, and a ruler movably mounted on the main body and having a plurality of graduations. Thus, the measuring and drawing angle of the combination measuring tool can be adjusted easily and freely, thereby facilitating a user operating the combination measuring tool to draw marking lines.
