Multi-functional compass

The utility model discloses a multi-functional compass for graph drawing. The multi-functional compass comprises a fixed rotating rod (1), a screw (2), a semicircular protractor (3), a penholder (4) with scales, a signing pen (5), a positioning rod (6), a positioning pin leg (7) and a rubber sleeve (8); and the multi-functional compass is characterized in that the penholder (4) of the compass is printed with the scales, the semicircular protractor (3) is fixed on the positioning rod (6) of the compass, and the rubber sleeve (8) is sleeved on the upper surface of the positioning pin leg of the compass. The multi-functional compass has the advantages that when the degree of an angle is required to be measured in the process of graph drawing, the measuring operation can be performed by using the protractor of the multi-functional compass, and the length of the radius of a circle can be accurately measured by using the scales on the pen leg of the compass, thereby achieving an multi-purpose effect; and when the u
