Furthermore; In the technique scheme; Described supporting seat is made up of the pencil axle and the supporting band tooth collar that is installed on the pencil axle; Wherein, the pencil axle is provided with the projection with the draw-in groove form fit, and slipping ring forms an integral body with iron plate, iron plate up and down and can move around by the projection guiding; The band tooth collar be provided with the circular hole that is complementary with the shrinkage pool of switch shrapnel form fit with the spring size and with the boss of pedestal secure fit, the band tooth collar, switch, three parts of spring are fixedly mounted on the pedestal.
Furthermore, in the technique scheme, described iron plate is to be formed along its central shaft bending downwards 90 degree by a bar shaped iron plate, and iron plate just is embedded in the draw-in groove and fixes with slipping ring.
Furthermore, in the technique scheme, described topping machanism is made up of knife rest and cutter head, forms a cone-shaped cavity between knife rest and the cutter head, and this iron plate places cone-shaped cavity terminal.
Furthermore, in the technique scheme, described Circuits System is provided with electronic delay on circuit, in switch broke off several seconds, can not rerun, and guarantees that pencil can be extracted fully can not receive cutting once more.
The utlity model has following beneficial effect:
1, the utility model is a propelling pencil machine, and electricity consumption work replaces traditional manual work, and the speed of cutting pencil is more accelerated.
2, the utility model has adopted the cutting of a kind of pencil to accomplish the autostop structure, makes to make people need not check whether pencil accomplishes cutting by pencil autostop after cutting is accomplished, and uses conveniently, also avoids the unnecessary consumption of pencil resource.

The specific embodiment:
Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.
As shown in Figure 1; The autostop structure is accomplished in a kind of pencil cutting; Comprise: casing, topping machanism, supporting seat and auto-stopper, described auto-stopper is made up of with iron plate 13 cooperations that are enclosed within the annulus 14 of slipping ring 12 rear ends and be fixed on the slipping ring 12 slipping ring 12 that is placed on the pencil axle 17; Described iron plate 13 is positioned at the topping machanism end; Described annulus 14 upper ends are connected with switch 16 shell fragments one end, and its lower end is connected with and the fixing spring 15 of casing, and these switch 16 other ends are connected with Circuits System 22.
Particularly; Described slipping ring 12 is one-body molded by two unequal annulus of radius, iron plate 121 and following iron plate 122 is set, wherein on the slipping ring 12; Following iron plate 122 front ends are provided with vertically downward a projection, form a draw-in groove 123 between last iron plate 121 and the following iron plate 122.Iron plate 13 is to be formed along its central shaft bending downwards 90 degree by a bar shaped iron plate, and iron plate 13 just is embedded in the draw-in groove 123 fixing with slipping ring 12.
Supporting seat is made up of the pencil axle 17 and the supporting band tooth collar 20 that is installed on the pencil axle 17; Wherein, Pencil axle 17 is provided with the projection 171 with draw-in groove 123 form fit; Slipping ring 12 is with iron plate, iron plate 121,122,13 formation one integral body can be moved around by projection 171 guiding up and down; The band tooth collar 20 be provided with the circular hole 202 that is complementary with the shrinkage pool 201 of switch 16 shell fragment form fit with spring 15 sizes and with the boss 203 of pedestal secure fit, the band tooth collar 20, switch 16,15 3 parts of spring are fixedly mounted on the pedestal 21.Topping machanism is made up of knife rest 18 and cutter head 19, forms a cone-shaped cavity between knife rest 18 and the cutter head 19, and this iron plate 13 places cone-shaped cavity terminal.
Like Fig. 2 to 5, after pencil insertion circular hole entered into the cone-shaped cavity of knife rest 18 and cutter head 19 formation, the cutter head 19 that pencil is rotated cut into centrum; Pointed portion promotes iron plate 13 after centrum reaches certain sharp degree; Iron plate 13 moves promotion slipping ring 12 and moves, and slipping ring 12 will move along pencil axle 17 backward this moment, and the annulus 14 that is enclosed within slipping ring 12 rear ends moves pull switch 16 shell fragments simultaneously; Make switch closure; Topping machanism stop motion this moment, the LED lamp that is arranged on the casing is bright, and the cutting of expression pencil is accomplished.Completion cutting back is extracted pencil out, and nib disappears to the pressure of iron plate 13, and annulus 14 promotes slipping ring 12 under the effect of spring 15 and switch 16 shell fragments, and slipping ring 12 promotes iron plate 13 reaches along 17 reaches of pencil axle, and switch 16 breaks off at this moment.The utility model is provided with electronic delay on circuit, at least 3 seconds inner machines can not move again after switch breaks off, and the assurance pencil can not extracted fully and can be cut once more, plays a protective role.
Certainly; The above is merely an embodiment of the utility model; Be not to limit the utility model practical range, all equivalences of doing according to the said structure of the utility model claim, characteristic and principle change or modify, and all should be included in the utility model claim.
