Description

Technical Field

[0001] The utility model relates to the technical field related to mathematical instruments, in particular to a mechanical mathematical exerciser. Background Art

[0002] Mathematics is a discipline that studies concepts such as quantity, structure, change, space, and information. Mathematics is a universal means for humans to rigorously describe and deduce the abstract structures and patterns of things. It can be applied to any problem in the real world. All mathematical objects are essentially artificially defined. In this sense, mathematics belongs to formal science rather than natural science. Different mathematicians and philosophers have a range of views on the exact scope and definition of mathematics. Mathematical concepts include parabolas. Parabolas are a basic curve in mathematics with unique mathematical properties and a wide range of applications. When drawing a parabola, auxiliary drawing practice tools are needed, so there is an urgent need for a mechanical mathematical exerciser.

[0003] The currently used mechanical math trainers are cumbersome to use and inconvenient to assemble and disassemble. In addition, since the mechanical trainers are made of metal, they are prone to corrosion and rust after long-term use. Utility Model Content
