Fig. 4 is the structural representation of the moulding ectosome of embodiment tri-;
Fig. 5 is the structural representation of embodiment San center rubber;
Fig. 6 is the enforcement structure with magnifying glass;
1. push endosome; 2. external screw thread; 3. internal thread; 4. moulding ectosome; 5. hole; 6. descend square hole; 7. rubber body; 8. center rubber; 9. device case; 10. stretch out rubber; 11. movable blocks; 12. conduits.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form restriction of the present utility model:
Embodiment mono-; In conjunction with Fig. 1
A kind of novel rubber eraser apparatus that prevents that mistake from wiping, it is characterized in that, comprise an above variform rubber extension, one of described rubber structure is following structure: A. comprises device case 9, on described device case 9, comprise more than one conduit 12, there is the rubber of stretching out 10 described conduit 12 inside, described in stretch out rubber 10 tops and have movable block 11, described movable block 11 can drive and stretch out rubber 10 and stretch out conduit 12, and more than one to stretch out rubber 10 diameter each other different.The technique effect of the essence that the technical scheme at this place plays is, can stretch out according to demand the rubber of different-diameter, wipes the lines of different thicknesses, can not make rubber part and cause mistake to wipe because wipe slightly to make to wipe.
As further improvement, described device case 9 comprises hollow cavity, and described hollow cavity avris comprises an opening.The technique effect of the essence that the technical scheme at this place plays is, hollow inside cavity can also be taken in the dirt on meticulous drawing, not so blows out, and all can not find on the ground for a moment, also cannot clean.
Described device case 9 one sides have magnet, also comprise hairbrush, and the pole of described hairbrush is irony, and described hairbrush attracts on device case 9.The technique effect of the essence that the technical scheme at this place plays is, hairbrush can be assisted cleaning, and hairbrush can clean the thing of drawing, because pencil can not disorderly be smeared, once disorderly smear and will cause a dirty, drawing is very ugly.
Described device case 9 surfaces are transparent, comprise a magnifying glass on it, and magnifying glass is positioned on housing.The technique effect of the essence that the technical scheme at this place plays is, can see as magnifying glass the part of figure.
Embodiment bis-, in conjunction with Fig. 2;
B. comprise center rubber, described center rubber stretches out more than one corner, and described corner is arc or wedge angle, and its shape is different.
The technique effect of the essence that the technical scheme at this place plays is, wiping of degree, because shape is different with thickness, can be carried out in a plurality of corners.
Embodiment tri-, in conjunction with Fig. 3, arrive Fig. 5;
C. comprise extruding endosome 1, described extruding endosome 1 outer end comprises external screw thread 2, also comprise moulding ectosome 4, on described moulding ectosome 4, comprise the different hole of more than one diameter 5, on described moulding ectosome 4 inwalls, there is internal thread 3, there is rubber body 7 described moulding ectosome 4 and extruding endosome 1 inside, and described rubber body 7 is soft rubber body, and external screw thread 2 and internal thread 3 can spiral shell suit and continue turn.The technique effect of the essence that the technical scheme at this place plays is as follows, 1. can allow the rubber of different pore size stretch by extruding, carries out wiping of different-diameter lines; 2. can make rubber continue to squeeze out is utilized.Described moulding ectosome 4 belows comprise lower square hole 6.
On described soft rubber body, itself comprise projection, described projection can be stretched out hole 5.This place provides a kind of basic shape that is extruded rubber, and this shape makes rubber be utilized better.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
