Multifunctional drawing tool for senior high school mathematics

Abstract

The invention discloses a multifunctional drawing tool for senior high school mathematics. The drawing tool comprises a bottom plate and a second fixed base; a motor is arranged on the surface of thebottom plate, the top end of an output shaft of the motor is connected with a first connecting block, the first connecting block is connected with a second connecting block through a first electric telescopic rod, the second connecting block is connected with a first fixed base through a second electric telescopic rod, the first fixed base and the second fixed base are correspondingly provided with connecting holes, connecting columns are rotatably connected in the connecting holes, and soft pads are arranged on the corresponding faces of the first fixed base and the second fixed base. According to the multifunctional drawing tool for senior high school mathematics, when drawing is carried out, a user carries out data input through a PLC, the PLC can control work of the motor, the first electric telescopic rod and the second electric telescopic rod according to input data, drawing work is achieved, drawing precision is improved, operation is easy, and a teacher can conveniently use thetool.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a multifunctional drawing tool for high school mathematics. Background technique [0002] High school mathematics is a subject learned by high school students across the country, including set functions, trigonometric functions, inequalities, sequence, complex numbers, permutations, combinations, binomial theorem, solid geometry, plane analytic geometry, etc. Sometimes it is necessary to draw when teaching Some graphics are easy for students to understand, but the current drawing tools have the disadvantages of single function, inaccurate drawing, and complicated operation, which is not convenient for teachers to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a multifunctional drawing tool for high school mathematics, which can meet most of the drawing needs, improve the ...
