Higher mathematics plotter

Abstract

The invention belongs to the technical field of advanced mathematics drawing equipment, and particularly relates to an advanced mathematics plotter which comprises a main body, a rotating rod capable of rotating to any angle is arranged in the main body, and a fixing plate is arranged on the outer side of one end of the main body. The interior of the main body is arranged to be of a through groove structure, the rotating rod can be rotated to any angle for drawing, a reset spring is further used for driving a gear shaft to automatically reset, the main body and the rotating rod are connected, and the rotating rod can be fixed to a certain angle to be prevented from loosening. Operation is simple, large circles can be drawn, meanwhile, radius disorder can be effectively prevented, and the using effect is improved; rotation of the rotating base can be relieved by pressing the rear end of the pressing rod downwards, at the moment, the rotating base is rotated, the spring on the outer side of the lower end of the supporting rod can drive the limiting pin to automatically reset in the positioning hole to fix the rotating base, a certain angle is kept between the suction cup and the clamping sleeve and the blackboard, and the phenomenon that the drawing effect is affected due to excessive inclination is prevented.

Description

technical field [0001] The invention belongs to the technical field of advanced mathematics drawing equipment, and in particular relates to an advanced mathematics drawing device. Background technique [0002] In the teaching process of advanced mathematics, teachers need to draw coordinate diagrams on the blackboard and various graphics to assist explanations. It is often very inconvenient and restrictive to draw coordinate axes with a ruler or a triangle used in ordinary teaching. An advanced mathematical plotter. [0003] The original plotter is inconvenient to draw some larger circles when using it, which leads to easy radius confusion when drawing larger circles, and when using it, due to the suction cup at the bottom and the chalk and the main body of the plotter It is set in parallel, so that when drawing a larger circle, the angle of inclination between the suction cup and the chalk and the blackboard is too small to affect the use, and most of the existing plotters...

[0002] In the teaching process of advanced mathematics, teachers need to draw coordinate diagrams on the blackboard and various graphics to assist explanations. It is often very inconvenient and restrictive to draw coordinate axes with a ruler or a triangle used in ordinary teaching. Advanced Mathematics Plotter

[0003] The original plotter is inconvenient to draw some larger circles when using it, which leads to easy radius confusion when drawing larger circles. It is set in parallel, so that when drawing a larger circle, the angle of inclination between the suction cup and the chalk and the blackboard is too small to affect the use, and most of the existing plotters have single functions, and can only draw some fixed lines. Teachers need to carry More drawing equipment is more troublesome, and it is inconvenient to take out the chalk when it is used to the last section, which affects teaching
