Abstract
The utility model relates to the mathematical formula training device field, particularly to a portable mathematical formula training device, so that a problem that students easily lose interest in math learning due to boring memorization of the mathematical formula can be solved. The portable mathematical formula training device comprises a rotating shaft I, a rotating shaft II, a sleeve, a mathematical formula tape, a reading screen, two plugs, two thumb wheels Is and two thumb wheels IIs. Specifically, the rotating shaft I and the rotating shaft II are arranged in parallel in the sleeve; the plugs are respectively installed at two ends of the sleeve; two ends of the rotating shaft I penetrate the plugs and are connected with the thumb wheels Is; and two ends of the rotating shaft II penetrate the plugs and are connected with the thumb wheels IIs. In addition, the mathematical formula tape is wound on the rotating shaft I and the rotating shaft II; a strip hole is arranged on the circular sleeve along the generatrix direction; and the reading screen is connected between the two plugs and is covered on the strip hole. According to the utility model, the portable mathematical formula training device has advantages of simple structure and convenient operation and usage.
Description
Technical field
The utility model relates to a kind of mathematical formulae exercising machine, is specifically related to a kind of portable mathematical formulae exercising machine.
Background technology
In mathematical studying, the memory mathematical formulae is a uninteresting thing, easily is sick of, and when the student begins to learn numerous and diverse formula, often can not grasp well mathematical formulae, holds books and memorize mechanicallys, and in the course of time, has just lost the learning interest to mathematics.
The utility model content
The purpose of this utility model is uninteresting in order to solve the student memory mathematical formulae, easily loses the problem of the learning interest of logarithm, and then a kind of portable mathematical formulae exercising machine is provided.
The technical solution of the utility model is: portable mathematical formulae exercising machine comprises rotating shaft I, rotating shaft II, sleeve, mathematical formulae band, recognition screen, two plugs, two thumb wheel I and two thumb wheel II; Rotating shaft I and rotating shaft II are set up in parallel in sleeve, the two ends of sleeve respectively are equipped with a plug, the two ends of rotating shaft I all pass plug and are connected with thumb wheel I, and the two ends of rotating shaft II all pass plug and are connected with thumb wheel II, are tied with the mathematical formulae band on rotating shaft I and the rotating shaft II, sleeve is circular sleeve, have strip hole along its generatrix direction on the sleeve, the recognition screen is connected between two plugs, and the recognition screen is installed in the strip hole place, the recognition screen is clear glass recognition screen, and sleeve is plastic sleeve.
The utility model compared with prior art has following effect: the utility model one-piece construction is simple, and is easy for operation, can freely carry, and do not need the books of leafing through, and strengthened the memory to mathematical formulae, improved the learning interest of student to mathematics.
