[0031] Please refer to Figures 1-6, the outer part of the disc 12 is fixedly connected with the separation line 14, nine separation lines 14 are equidistantly arranged in a circle on one side of the disc 12, and the numbers in each first annular array 13 are located between two separation lines 14, in the scheme, the nine equidistantly arranged separation lines 14 divide the disc 12 into nine large exclusive areas, and each area precisely frames a single number such as '3' in the first annular array 13 fixed in the third partition, and the grid layout makes the number distribution more orderly, the user can quickly locate the target number through the separation line 14, avoids visual confusion caused by dense arrangement of numbers, and the physical boundary formed by the separation line 14 is linked with the magnetic attraction clamping point of the rotating disc 17, when the iron block 19 of the rotating disc 17 is attracted to the magnet 16 of the disc 12, the numbers of the second annular array 18 are automatically aligned to the corresponding separation area, for example, when the number '5' of the rotating disc 17 is rotated to be magnetically locked with the separation area where the number '6' is located, the 5th multiple value of '6' in the linear array 15, that is, 30, is just located in the area, through the operation loop of 'partitioning, positioning and alignment', the user operation path is forced to be standardized, and the misoperation rate of the formula derivation is reduced.

[0032] Please refer to Figures 1-6 , each linear array 15 derived from 1 to 9 is located between two separation lines 14.

[0033] Please refer to Figures 1-6 , the center of the disc 12 is fixedly connected with a fixed shaft 22, the outer part of the fixed shaft 22 is provided with a rotating disc 17, the outer wall of the rotating disc 17 is fixedly connected with nine iron blocks 19, one side of the disc 12 is fixedly connected with nine magnets 16, and the nine magnets 16 and the iron blocks 19 are equidistantly arranged in a circle, in the scheme, the nine equidistantly arranged magnets 16 and the iron blocks 19 form a precise clamping system, when the rotating disc 17 rotates, magnetic attraction locking is triggered once every 40° of rotation, the physical limiting mechanism makes the numbers such as '5' of the second annular array 18 of the rotating disc 17 be precisely aligned with the numbers such as '6' of the first annular array 13 of the disc 12, and ensures that the corresponding product 6*5=30 in the linear array 15 is automatically presented in the observation visual angle, the positioning error is less than ±1.5°, the positioning precision is improved by 70% compared with the traditional rotary knob type, and formula display errors caused by angle deviation are effectively avoided.

[0035] Please refer to Figures 1-6, the outer wall of the rotating disc 17 is printed with a second annular number series 18, which is a series of numbers from 1 to 9. In this scheme, the second annular number series 18 and the first annular number series 13 of the disc 12 form a “multiplier × multiplicand” double-axis interactive system. Through the rotation of the rotating disc 17, the numbers from 1 to 9 can be freely combined into 81 kinds of multiplication formulas, such as the disc 12 “6” corresponding to the rotating disc 17 “7” to form 6 × 7.

The circular hole 21 at the center of the rotating disc 17 and the fixed shaft 22 form a coaxial rotating pair to ensure stable rotation without deviation. At the same time, the iron block 19 on the outer wall of the rotating disc 17 and the magnet 16 on the disc 12 are arranged in an equidistant circular array to generate a magnetic attraction force. Every 40° rotation triggers a click point positioning, which makes the numbers of the second annular number series 18 accurately align with the numbers 1-9 of the first annular number series 13 of the disc 12.

[0038] When the numbers of the rotating disc 17 and the disc 12 are locked by magnetic attraction, such as the rotating disc 17 “5” aligning with the disc 12 “6”, the corresponding relationship activates the calculation function of the linear number series 15:

[0039] The linear number series 15 of the disc 12 takes the numbers of the first annular number series 13 as the base, and forms an equidistant radial arrangement according to the multiples, such as the number series corresponding to “6”: 6→12→18…54;

[0040] The display slots 2 of the rotating disc 17 are arranged in a radial direction, and their serial numbers correspond to the multiple levels of the linear number series 15, such as the fifth display slot 2 corresponding to the fifth multiple of the base;
