Diameter.
Compared with prior art, the utility model has the beneficial effects that the utility model is novel in design, structure is simple, leads to
It crosses and rack gear bottom is provided with sphere, sphere is connected with sucker by ball groove, and rack gear slidably connects sliding block, increases device
Stability and functionality, slider bottom are connected with clamp system by cylinder, effectively prevent chalk and occur in drawing processes
Fracture slides, easy to operate, saves the time needed for drawing.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model clamp system structural schematic diagram.
In figure: 1 rack gear, 2 suckers, 21 pedestals, 211 ball grooves, 3 columns, 4 spheres, 5 sliding blocks, 6 through-holes, 7 clamping screws, 8
Body, 9 clamp systems, 91 hollow round table, 911 notches, 92 snap rings, 10 handles, 11 graduation marks.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, belongs to the range of this practical protection.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of novel mathematics teaching teaching aid, including tooth
Item 1 and sucker 2, the rack gear 1 are rectangular plate-like structure, and 1 left bottom of rack gear is equipped with column 3, and 3 end of column is equipped with
Sphere 4 is equipped with pedestal 21 at the top of the sucker 2, and 21 surface of pedestal is provided with ball groove 211, between the ball groove 211 and sphere 4
