摘　　要：介绍了一种双曲线及抛物线的绘制工具,它的工作原理是模拟圆锥面与平面相交所产生的截交线的形成过程,从而实现了双曲线及抛物线的绘制;并就实现双曲线及抛物线轨迹建立了数学模型。An apparatus designed to draw hyperbola and parabola is introduced in this paper, by simulating the intersecting process forming an intersecting line by a coin and a plane. Hence, it's possible to draw hyperbola and parabola, and the mathematical models to form the hyperbola and the parabola locus are established. Meanwhile, it also explains how to use the drawing apparatus.
