Abstract
A function coordinates demonstration instrument belongs to the teaching instrument technical field. The utility model includes that technical scheme that: the demonstration instrument comprises an iron cross scale coordinates and flexible aluminum wires, and a string of magnetic beads are fixed on the flexible aluminum wires. The function coordinates demonstration instrument has simple structure, convenient operation for function study, is time and labor saving and reduces the working difficulty of students and teachers.
Description
Technical field: the utility model belongs to the schooling apparatus technical field, is a kind of function coordinate demonstrator specifically.
Background technology: at present, in the function learning process, need manual picture function coordinate diagram mostly, and demonstration all needs the new figure of picture one width of cloth each time, operating so very bothers, wastes time and energy, and has increased great work difficulty to student and teacher.
Summary of the invention: the purpose of this utility model provides a kind of function coordinate demonstrator easy and simple to handle, time saving and energy saving in the function learning process.
The technical solution of the utility model is: comprise iron " ten " word graduated scale and soft aluminium wire, it is characterized in that being fixed with a string magnetic ball on soft aluminium wire.
The beneficial effects of the utility model are: the utility model is simple in structure, and is easy and simple to handle in the function learning process, time saving and energy saving, alleviated student and teacher's work difficulty.
Description of drawings: accompanying drawing 1 is a structural representation of the present utility model.
Among the figure 1, iron " ten " word graduated scale, 2, soft aluminium wire, 3, the magnetic ball.
Embodiment: comprise iron " ten " word graduated scale 1 and soft aluminium wire 2, it is characterized in that on soft aluminium wire 2, being fixed with a string magnetic ball 3.In the function learning process, the soft aluminium wire 2 of manual adjustment makes it become required parabola state, is adsorbed on iron " ten " the word graduated scale 1 by magnetic ball 3 then to get final product.
