Multifunctional mathematical coordinatometer

Abstract

The invention discloses a multifunctional mathematical coordinatometer. The multifunctional mathematical coordinatometer comprises a base. An installing groove is formed in the rear end face of the base, a sucker is installed in the installing groove, a main ruler is arranged on the side face of the base, and a magnetic strip is arranged on the rear end face of the main ruler. A strip-shaped clamping groove is formed in the upper surface of the main ruler, a third auxiliary ruler is arranged in the strip-shaped clamping groove, the right end of the third auxiliary ruler is movably connected with the strip-shaped clamping groove through a clamping post in a clamped mode, and a lifting piece is arranged at the left end of the third auxiliary ruler. A compass is arranged at the right end of the front end face of the main ruler, a rotary shaft is arranged in a round groove in the middle of the front end face of the base, the side face of the rotary shaft is sleeved with a rotary disc, and the side face of the rotary disc is provided with a rotary ruler. The whole multifunctional mathematical coordinatometer is simple in structure, small in occupied space and easy and convenient to operate; arcs with different sizes and angles can be drawn, simple two-dimensional and three-dimensional coordinate systems can be established, students more easily learn and understand knowledge, and compared with a traditional drawing tool, the multifunctional mathematical coordinatometer is more convenient to use and more practical.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a multifunctional mathematical coordinate ruler. Background technique [0002] In teaching activities, teaching aids have played a very important role, especially in the subject of mathematics and geometry. The aids used are rulers, triangles, compasses, etc., but the existing tools often have many limitations and cannot draw Angle at any angle, and it is inconvenient to measure the degree of angle on the blackboard. When drawing a circle with a teaching compass, it is easy to cause damage to the blackboard, and there is a certain degree of danger. In addition, while learning the two-dimensional and three-dimensional coordinate system, some spatial imagination It is more difficult for limited students to learn, so we propose a multifunctional mathematical coordinate ruler. Contents of the invention [0003] The purpose of the present invention is to provide a multifuncti...
