    摘要： A compass, comprising a sliding rod with a handle at an upper end, and a drawing portion. A slider is slidably mounted on the sliding rod. Two links are pivotally connected to the slider and to the drawing portion at respective first pivot points forming at least approximately a parallelogram. A crank is operatively pivotally connected to the sliding rod and to a center of one of the links at respective pivot points, the crank having a length between its pivot points equal to half the length of the link to which the crank is connected between the first pivot points of the one link.

    摘要： 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.

    摘要： A combination tool assembly is disclosed having a pentagonal top block detachably fastened to an elongated, pentagonal base through doweled joints, a folding rule pivoted to the top block and received in a side chamber on the base, a cutter and ballpoint pens controlled by slides to move in and out of respective holes on the base, a triangular scale detachably side matched to the top block and the base. The folding rule may be separately used for measuring and arranged with the base into an instrument for drawing circles.
