Abstract
The utility model discloses a novel combined mechanism compass which comprises a sucking disc, a pointer sliding block, a compass supporting rod, connecting rods, two compass turning poles and a positioning sliding block, wherein the compass supporting rod, the pointer sliding block, the connecting rods, one compass turning pole and the positioning sliding block constitute an elliptical mechanism; the pointer sliding block, the positioning sliding block and the two compass turning poles constitute a parallel mechanism. The pointer sliding block slides along a sliding groove in the compass supporting rod and drives the compass turning poles and the connecting rods to rotate, and a radius can be determined according to scales on the compass supporting rod; at the same time, the two compass turning poles ensure that a paintbrush connected to the positioning sliding block is always perpendicular to a drawing plane; the sucking disc adsorbs a blackboard plane or a principal plane, and an angle can be determined according to an angle scale at the lower end of the compass supporting rod; the compass supporting rod is rotated around a rotating shaft at the upper end of the sucking disc to drive the paintbrush to draw a picture. According to the novel combined mechanism compass, the radius and the angle can be directly determined when a circle and an arc are drawn, the positioning is accurate, the structure is compact, the operation is convenient, and higher popularization and application values are realized.
