Embodiment 1
[0080] like Figure 1-Figure 8 As shown in the figure, this embodiment provides a hundred-element learning slide rule, which includes a base body 1, and a plurality of mutually parallel slide grooves 12 are arranged in a row in the base body 1. As a decimal element, a plurality of sliding pieces can be independently extended and retracted along the chute 12 , so that different sliding pieces are exposed outside the base body 1 .
[0081] The slider has a decimal printing area 7 and a decimal printing area 8, and the marked number of decimal elements in different sliders is the same.
[0082] The surface of the base body 1 forms a marking surface, and the marking surface and the sliders together indicate the decimal elements, the marking surface and each slider are marked with 20 decimal elements, and the number of the sliders is four.
[0083] It can be understood that, in this embodiment, the number of buttons is also four, that is, the first button 3 , the second button 4 ,...
Embodiment 2
[0093] like Figure 9-Figure 12 As shown, a hundred-element learning slider is also provided. The difference between this embodiment and Embodiment 1 is that the slider includes two half-sliders, and the two half-sliders are spliced to form a slider, and each half-slider is The end of the sliding piece is provided with a semi-convex piece, the two sliding pieces are respectively used to indicate the decimal element and the corresponding decimal element value, and the two semi-convex pieces are spliced to form a convex piece; The width direction of the sheet is slid and positioned so that the buttons are respectively aligned with the two half-tabs used together, so that the two half-slides can be independently extended and retracted.
[0094] The number of the upper buckles 10 in each chute 12 is two, and one of the lower buckles 9 is respectively provided on each half-tab.
[0095] Specifically, the drawings in the description exemplarily show a schematic diagram of dispo...
