Problems solved by technology
[0003] The purpose of the present invention is to provide a circle drawing tool, which can effectively solve the problem that the sharp pivot points of the circle drawing tools in the prior art are easy to accidentally injure others. The existing circle drawing tools are not suitable for use on glass surfaces or polyester films or other The problem of drawing circles on easily damaged planes; the invention provides a circle drawing device suitable for teaching blackboards, engineering drawings or film circles, and the invention can be used to draw circles, concentric circles or tangent circles , which has many advantages such as novel structure, convenient use, strong practicability, etc.

The invention relates to the field of circle drawing tools, in particular to a cyclograph. The cyclograph comprises a fixing base, supporting frame devices, a rocker type rotation device, an auxiliary arc drawing device, a connecting rod device, an inner circle drawing device and an outer circle drawing device. The three supporting frame devices are connected to the outer side of the fixing base. The rocker type rotation device is connected and installed to the middle of the top end of the fixing base. The lower end of the rocker type rotation device penetrates the fixing base and is connected with the upper end of the connecting rod device. The lower end of the connecting rod device is sequentially connected with the inner circle drawing device and the outer circle drawing device from top to bottom. The cyclograph suitable for teaching blackboards, engineering drawing or film circle drawing is provided, and the cyclograph can be used for drawing circles, concentric circles or tangent circles and has multiple beneficial effects of being novel in structure, convenient and fast to use, high in practicability and the like.
Description
technical field [0001] The invention relates to the field of graphic drawing tools, in particular to a circler. Background technique [0002] A circle is one of the common graphics in people's daily life and work life. The structure of the existing circle drawing tools is mainly a conventional compass structure. This type of circle drawing tools needs sharp pivot points to realize circle drawing. Not only is the sharp pivot point a risk of accidental injury when in use, but these circle tools are not suitable for use on hard surfaces, such as glass often encountered in overhead projectors; these circle tools are also not suitable For use on soft surfaces such as Mylar. Sharp pivot points can damage the surface on which the circle is drawn, such as leaving pinholes in mylar surfaces or permanently scratching glass surfaces. In addition, the existing circle drawing tool can only be used to draw a single circle, but cannot conveniently draw concentric circles or tangent circl...
