Abstract

The invention discloses a portable function teaching instrument comprising an instrument box. Both sides inside the instrument box are provided with sliders. A first chute is opened in one side of each slider. A support block is disposed at the top of the first chutes. Both sides of the support block are provided with recesses. Both sides inside the support block are provided with gear levers. The top of the support block is connected with a first panel. Both sides of the top on the back of the first panel are connected to a second panel through first hinges. A horizontal bar is disposed on the front face of magnet blocks. A third chute is opened in the front face of the horizontal bar. A pulley is disposed on the inner side of the third chute. The front face of the pulley is connected with an indicating lever. Both sides of the top on the back of the instrument box are connected to a door through second hinges. A handle is attached to the right side of the instrument box. The portable function teaching instrument has the advantage of being easy to carry, and solves the problem that the inconvenience of carrying can reduce the practicality of the function teaching instrument.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a portable function teaching and explaining appliance. Background technique [0002] The name of the function comes from Mathematician Li Shanlan's book "Algebra". Changes with changes in another quantity, or one quantity contains another quantity. [0003] At present, when teachers explain parabolic functions, they usually use function teaching tools. Hand-painted graphics on the teaching tools are convenient for students to observe the teacher's operation steps intuitively, and at the same time, it is easy for students to understand, which promotes students' enthusiasm in learning functions. The learning efficiency of the students is improved, but the existing function teaching tools are not easy to carry after use, thereby reducing the practicability of the function teaching tools. Contents of the invention [0004] The purpose of the present invention is to pr...
