[0020] Furthermore, each of the openings 4 is communicated with the inner cavity of the main body 3 .
[0021] According to the above technical solution, by providing the hollow opening 4 on the upper side of the main body 3, the user can clearly see the numbers 10 on the outer side of the adjusting roller 9, which is helpful for vertical calculation.
[0022] It should be noted that the number of the two rows of empty openings 4 on the upper side of one side of the main body 3 can be increased or decreased according to actual needs; if the calculator is simply used for mathematics exercises for young children, not too many are needed; if the calculator is used by people of all ages, the number of empty openings 4 in each row will be increased accordingly, and four empty openings 4 arranged together represent thousands of digits.
[0023] It should be noted that, normally, the number of the openings 4 on the upper side of the other side of the main body 3 should match the result of multiplying the two largest thousand-digit numbers, such as 9900×9900=98010000, so eight rectangular openings 4 should be set on the upper side of the other side of the main body 3.
[0024] See also Figure 2 Two rows of brackets 8 for mounting the number 10 roller 9 are provided on the lower side of one side of the main body 3 as required, and each row of brackets 8 has at least four brackets 8; a bracket 8 for mounting the symbol 11 roller 9 is provided at one end of the lower side of one side of the main body 3; at least five brackets 8 for mounting the numerical result roller 9 are provided on the lower side of the other side of the main body 3, each U-shaped bracket 8 faces an empty opening 4, and a circular shaft hole for embedding the shaft rod of the roller 9 is provided in the center of the upper part of the plate body on both sides of each bracket 8.
[0025] Furthermore, the lower side of each bracket 8 is fixed to the lower side of the corresponding main body 3 by welding glue.
[0026] Through the above technical solution, by setting the U-shaped bracket 8, the roller 9 can be stabilized and the center of gravity of the roller 9 can be balanced.
[0027] See also Figure 3Each bracket 8 is equipped with a matching circular roller 9, the outer circle of the roller 9 is an eleven-sided structure, that is, each roller 9 is provided with eleven horizontal planes on its outer circle, the roller 9 diameter is less than the height inside the main body 3, the roller 9 diameter and thickness = the height and width inside the bracket 8, the horizontal plane length and width of the outer circle of the roller 9 are 1.3 cm and 1.2 cm respectively, each roller 9 is made of semi-soft silicone, and each roller 9 is provided with a 0.5 cm long cylindrical shaft in the center of both sides, and the shafts on both sides of each roller 9 are respectively embedded in the corresponding shaft holes on the upper part of one side of the bracket 8, and then extend outward for a while.
[0028] The numbers 10 of 0-9 are set on the horizontal surfaces of the two rows of rollers 9 on the lower side of one side of the main body 3; the addition, subtraction, multiplication and division symbols 11 are set on the horizontal surface of the roller 9 at one end of the lower side of one side of the main body 3, and the eleven horizontal surfaces of the outer circle of the roller 9 are set as spaces except for the four symbols of addition, subtraction, multiplication and division; the numbers 10 of 0-9 are set on the horizontal surfaces of the five rollers 9 on the lower side of the other side of the main body 3.
[0029] Furthermore, each number 10 is fixed on the horizontal plane of the outer circle of the corresponding roller 9 by welding glue, and each number 10 is made of silicone with eye-catching colors.
[0030] Through the above technical solution, by setting eye-catching numbers 10 from 0 to 9 on the horizontal plane of the outer circle of the roller 9, the operator can effectively arrange and integrate the numbers 10, thereby improving the speed of vertical calculation.
[0031] Furthermore, a space is provided on a horizontal plane of the outer circumference of each roller 9 .
[0032] According to the above technical solution, a space is provided on a horizontal plane of the outer circle of the roller 9, so that the previous largest digit can be identified, which is beneficial to the adjustment and distinction between the digits.
[0033] Furthermore, each symbol 11 is fixed on the horizontal plane of the outer circle of the corresponding roller 9 by welding glue, and each symbol 11 is made of silicone with eye-catching colors.
[0034] Through the above technical solution, by setting the addition, subtraction, multiplication and division symbols 11 on the horizontal plane of the outer circle of the roller 9, various types of digital 10 operations are facilitated.

[0038] It should be noted that, under normal circumstances, a horizontal plane of the outer circle of each roller 9 is in contact with the inner outer edge of the corresponding hollow opening 4; the roller 9 has a certain flexibility, and when the dial wheel 12 drives the roller 9, the outer corner of the roller 9 will shrink to a limited extent after contacting the inner outer edge of the hollow opening 4, and pass through tightly.
[0039] join Figure 5 A matching transparent panel is provided on the inner side of each hollow opening 4, and the panel is also called a pure acrylic light-transmitting panel. Each panel is fixed on the inner side of the corresponding hollow opening 4 by hot-melt technology. The upper side of the panel is as flat as the upper side of the main body 3, and the thickness of the panel is equal to the thickness of the upper panel of the main body 3.
[0040] In order to facilitate understanding and distinction of the various components, the panel in this application is not numbered and is only described in words; the reason is that the panel has good transparency and is easily confused with the number 10 on the roller 9.
[0041] It should be noted that when the horizontal surface of the outer circle of the roller 9 faces the upper empty opening 4, the number 10 or symbol 11 on the horizontal surface is located in the empty opening 4; when each dial 12 is installed, the outer circle of one side of each dial 12 will pass through the corresponding side groove 5 and expose a small part.
[0042] In actual operation, the user turns the dial wheel 12 and drives the roller 9. As the roller 9 rotates, the numbers 10 or symbols 11 on the outer circle thereof are clearly displayed one by one for the user to select.
[0043] It should be noted that when two groups or two numbers 10 are calculated, the largest digit should be preceded by a space, indicating that there is no larger digit in front of the largest digit. The following takes 150-90=60 as an example.
[0044] 1. Adjust the number 10 on the outer circle of the first row of rollers 9 from the ones digit 0, tens digit 5, and hundreds digit 1 in sequence, and then adjust the outer circle of the roller 9 in front of the hundreds digit 1 to a space; 2. Adjust the number 10 on the outer circle of the second row of rollers 9 from the ones digit 0, tens digit 9 in sequence, and then adjust the outer circle of each roller 9 in front of the tens digit 9 to a space; 3. When calculating the numerical result, adjust it from the ones digit 0, tens digit 6 in sequence, and then adjust the outer circle of the roller 9 in front of 6 to a space. The actual result is displayed as 60.
[0045] It should be noted that in actual operation, the user moves the dial wheel 12 with a single finger, and the dial wheel 12 drives the roller 9 through the shaft rod on one side thereof, so that the number 10 is arranged vertically.
[0046] join Figure 6 When the cover plate 1 covers the upper side of the main body 3 , the magnet sheet 2 on the outer edge of one side of the cover plate 1 has tightly attracted the iron sheet 6 on the upper outer edge of the other side of the main body 3 .
