In a cutting device for cutting a round, a transparent substrate is arranged on an object to be cut. A sleeving tube is arranged on the transparent substrate. An end of a transverse rod penetrates through the sleeving rod and extends to over the object. The position of the transverse rod in the sleeving rod is adjusted by a locking member. The other end of the transverse rod is fixed to a cutting assembly. The cutting assembly selectively touches the object. A rotating assembly is combined with the transparent substrate and penetrates through the transparent substrate. When the rotating assembly is pressed to touch the object and the rotating assembly rotates on the object to rotate the transparent substrate, the transverse rod moves the cutting assembly to perform a round-cutting operation on the object or paint a round line on the object.
