Abstract

The utility model discloses a mathematics charting tool. A handle (2) of the mathematics charting tool is arranged at the left end of a supporting plate (1), and a carbon refill (5) is fixed in a clamping seat (4) through a fastening screw (6) and is movably fixed in a clamping groove (8) through a fixing screw (7). Since a supporting plate marked with scales and the movable clamping seat are designed, a fixing needle is utilized to be matched with the carbon refill during charting to complete charting functions as required, various charting and calculating tools are omitted, the mathematics charting tool is easy to carry and convenient to use, charting efficiency is high, and charting is accurate.

Description

Mathematics drawing apparatus
Technical field: the utility model relates to a kind of mathematical education apparatus.
Background technology: known when mathematics charts at present, often need compasses, protractor, length ruler and computational tool etc.These drafting instruments use inconvenience, and can not directly draw out desired pattern because the sample number is many, not portable.
The utility model content: the purpose of this utility model has been to overcome the drawback that exists when existing mathematics charts.Provide and to have saved various drawing and computational tool, be easy to carry about with one, a kind of mathematics drawing apparatus easy to use.The technical scheme that its technical problem that solves the utility model adopts is: its handle 2 is arranged on support plate 1 left end, and carbon element pen core 5 usefulness trip bolts 6 are fixed in the deck 4, and are fixed in the draw-in groove 8 by hold-down nut 7 activities.
The beneficial effects of the utility model are: because the utility model has designed one and indicated scale value support plate and movable deck, when drawing, utilize locking pin to cooperate the carbon element pen core, can finish desired drawing function, various drawing and computational tool have been saved, and be easy to carry about with one, easy to use, especially efficient significantly improves when the large-sized drawing of system, and draws accurately.
Description of drawings: Fig. 1 is front view of the present utility model
Fig. 2 is the vertical view of Fig. 1
The specific embodiment: as shown in Figure 1 and Figure 2, its handle 2 is arranged on support plate 1 left end, and carbon element pen core 5 usefulness trip bolts 6 are fixed in the deck 4, and are fixed in the draw-in groove 8 by hold-down nut 7 activities.
As shown in Figure 1 and Figure 2, described handle 2 lower ends arrange locking pin 3.
As shown in Figure 1 and Figure 2, described draw-in groove 8 is arranged on the interior middle part of support plate 1, and both sides equidistantly indicate scale value 9.

Claims (3)
