Abstract

The invention discloses an auxiliary drawing tool used for elliptical teaching. The drawing tool comprises a drawing frame. The bottom of the drawing frame is fixedly bonded with a magnetic suction strip. The top of the drawing frame is provided with a rotation mechanism. The tool relates to the auxiliary teaching apparatus technology field. A cross clamping design mode is adopted, the tool is fixed to a blackboard through a magnetic attraction principle so that drawing is performed, and a drawing teaching speed is increased and simultaneously drawing visual quality is ensured. A hard materialdesign is adopted and a bottom is provided with a magnetic attraction structure. On one hand, an adsorption area can be increased and sliding is not generated during drawing; on the other hand, a drawing track is accurately limited and a drawing ornamental value is increased. A guide wheel is mainly used for reducing the frictional force of an internal mechanism during operating and increasing drawing fluency, and simultaneously, during movement, the guide wheel can crush chalk dust so that conditions that equipment is stuck and operation difficulty is increased are prevented.

Description

technical field [0001] The invention relates to the technical field of auxiliary teaching equipment, in particular to an auxiliary drawing tool for ellipse teaching. Background technique [0002] In daily teaching work, educators often use some teaching equipment. Using equipment to assist teaching can not only improve the interest and enthusiasm of students, but also help students better understand and master the learning content. Among them, geometry A series of drawing tools need to be used in teaching. The ellipse is a relatively important chapter in the geometry teaching content, so the teacher often needs to draw and explain on the blackboard. [0003] At present, when teaching geometry, some of the more common aids have rulers of various shapes and compasses for drawing circles on the blackboard, etc., but there is still a lack of tools that can draw some more irregular figures, such as drawing on the blackboard Ellipse tool. [0004] Disclosed as Chinese patent " a...
