Abstract
The utility model discloses an electronic pencil sharpener which is composed of a cell box, a cutting box, a knife box and a pencil sharpening hole. A micro driving motor is arranged on a joint of the cell box and the cutting box, and a contact switch is arranged on a joint of the pencil sharpening hole and the pencil sharpening hole and the cutting box. In order not to waste resources, the contact switch has a main function that when a pencil is cut to the appropriate length and the fineness, a pencil lead abuts against the contact switch, the motor is powered off due to the fact that the pencil lead abuts against the contact switch, and accordingly the aim of automatically stopping sharpening the pencil is achieved. Therefore, the aims of safety, stability and high efficiency in the pencil sharpening process, and particularly the aims of not wasting the resources are achieved.
Description
Technical field
The utility model relates to a kind of pencil sharpener, relates in particular to the electronics pencil sharpener.
Background technology
Pencil sharpener one is established a capital can be not strange, and it is the instrument that sharpens a pencil.In the time of the 17th century, people just sharpen a pencil with cutter.With the progress of work society, to 19 beginnings of the century, people not only need use more pencil, and also there has been higher requirement the time of the cost that sharpens a pencil.The pencil sharpener of theory of mechanics is given birth under this environment at once.First such pencil sharpener is Frenchman's invention in 1828 in the world.In ensuing several centuries, pencil sharpener has developed into the appearance that present people knew gradually.
Pencil sharpener golden age the chances are last century the mid-80 to the initial stage nineties.At the beginning of the nineties, automatic or electronic pencil sharpener has appearred.Traditional pencil sharpener has then slowly withdrawed from the arena of history.
Pencil sharpener and pencil sharpener also have two big weak points: the nib that one of which is cut out is point too, is prone to scratch paper when writing, and nib fractures easily, because nib thickness difference is too big, when writing, causes writing inhomogeneous; The second, blade or milling cutter are too big to the cutting output of pencil-lead, and lead for retractable pencil most of actual that reamed rather than write wasted very big.
The utility model content
The utility model provides a kind of according to above-mentioned deficiency
Be to realize above-mentioned purpose, the technical scheme of the utility model is the electronics pencil sharpener, by battery case, cut box, cutter box, pen-rolling hole and forms, and described battery case and cut the box junction and be provided with a micro drives motor.Be used to drive the described box of cutting, lay No. 7 dry cells of two joints in the battery case and drive micro motor.
Described pen-rolling hole and the described box junction of cutting are provided with a contact switch; In order not waste the resource contact switch is that main effect is to work as pencil sharper to the length that meets; Pen core this contact switch of conflicting during fineness, thus contact switch is opened and is made the motor outage reach the purpose that stops to cut pen automatically because supported by pen core.
Described micro drives motor connects the described box of cutting; Cutting box is connected with pen-rolling hole is coaxial; The rotary speed of control and grasp pen-rolling hole; Thereby reach safety, stable, efficiently, do not waste the purpose of cutting pen, what described cutter box was placed in that the cutter box is installed above the described pen-rolling hole is common pencil sharpener blade.
The beneficial effect of technique scheme is: through technique scheme, cut a process safe thereby reached, and stable, efficiently especially reached the purpose of not wasting resource.
Description of drawings
Fig. 1 is the structure chart of the utility model;
The specific embodiment
Do bright specifically below in conjunction with the accompanying drawing and the specific embodiment to the present invention; By shown in Figure 1; Shown in the utility model electronics pencil sharpener structure chart, by battery case 3, cut box 5, cutter box 1, pen-rolling hole 2 and form, battery case 3 with cut box 6 junctions and be provided with a micro drives motor 6.Be used to drive the described box 5 of cutting, lay No. 7 dry cells of two joints in the battery case 3 and drive micro motor 6; Pen-rolling hole 2 is provided with a contact switch 4 with described box 5 junctions of cutting; In order not waste resource contact switch 4 is that main effect is to work as pencil sharper to the length that meets; Pen core this contact switch of conflicting during fineness, thus contact switch 4 is opened and is made the motor outage reach the purpose that stops to cut pen automatically because supported by pen core.
The micro drives motor connects the described box of cutting; Cutting box is connected with pen-rolling hole is coaxial; Control is also grasped the rotary speed of pen-rolling hole, thus reach safety, stable, efficiently, do not waste the purpose of cutting pen, what described cutter box was placed in that the cutter box is installed above the described pen-rolling hole is common pencil sharpener blade.
The utility model can be done multiple different appearance according to the different market demands, to satisfy different people's age custom, hobby, hobby.Market prospects are wide.
Through technique scheme, cut a process safe thereby reached, stable, efficiently especially reached the purpose of not wasting resource.
