Abstract
The utility model provides a simple easy-to-use sharpening device for an active pencil, suitable for an active pencil with a thicker pencil lead. The sharpening device consists of a sharpening and cutting cavity composed of 4 small blades. The composed cavity is same to the sharpened tapered pencil tip with a thicker pencil lead in the shape. A pencil lead to be sharpened is inserted in the cavity for rotation and sharpening. The sharpened part of the pencil lead is subjected to the balanced force in the tapered sharpening and cutting cavity, the pencil lead is sharpened quickly and is not easy to be broken, resolving the difficulties that the active pencil lead is easy to be broken and the sharpening speed is slow. The sharpening device is simple in the structure, durable and suitable for the active pencil, causing that the active pencils with thicker pencil leads are easy to be promoted and saving a great deal of materials and paper materials for pencil shaft with a environmental protection and energy conservation effect.
Description
Affiliated technical field
The utility model relates to the sharpening apparatus that a kind of propelling pencil uses, and the quick and pencil-lead of the core that especially sharpens a pencil is frangibility not.
Background technology
At present, when propelling pencil is used thicker pencil-lead, need cut pencil-lead and cut and could use, known propelling pencil sharpening apparatus style is few, and complex structure, when propelling pencil was cut core, pencil-lead was cut to cut partly and only be subjected to the unidirectional pressure of a slice blade knife edge in the space, is subjected to force unbalance, when there is swing propelling pencil penholder position slightly, pencil-lead just fractures easily, and the core process that sharpens a pencil is careful cautiously, and speed is very slow.
Summary of the invention
In order to overcome existing propelling pencil sharpening apparatus complex structure, speed is slow when sharpening a pencil core, and pencil-lead fractures easily, be difficult to grasp deficiencies such as cutting a quality, the utility model provides a kind of propelling pencil sharpening apparatus, and is simple in structure, and the core that sharpens a pencil is quick, pencil-lead is frangibility not, implements easily, and is durable in use.
The technical scheme that its technical problem that solves the utility model adopts is: by the main body top entity of 4 small blades, column type, columniform hole, sharpening apparatus lid, plug, cylindrical cavity, the pencil bits of dress pencil bits are removed mouth, cap is formed the propelling pencil sharpening apparatus.4 small blade centers of being fixed on have the cylindrical entity of columniform hole, the 4 small blade knife edge one end end points are got together, per two pairs of knifes edge are formed the V font, the knife edge in opposite directions, become symmetric configuration, article four, the knife edge is formed a pinnacle taper down and is cut and cut cavity in columniform hole, taper cut cut cavity size with cut partly size is identical than the taper nib of lead bullion pen core, cut and cut cavity and when rotating when the pencil-lead of propelling pencil inserts taper, the knife edge and pencil-lead are cut the vertical chamfer degree of cutting that is rotated into that cuts partly.Propelling pencil is done the circumference rotation or come back rotation, just can finish cutting of pencil-lead cut.Pencil-lead is cut and cut the pressure that partly is subjected to from 4 directions of 4 blade knifes edge in the space during rotation, stress balance, and the place that propelling pencil contacts with sharpening apparatus is few, just pencil-lead and four knife edge linearities of small blade contacts, pencil-lead has its swing space among a small circle, so when propelling pencil rotated, pencil-lead is frangibility not, article 4, the knife edge is cut pencil-lead simultaneously and is cut, and pen core is cut sooner.The shank of column type separate be sharpening apparatus partly, cap partly.
The sharpening apparatus lid partly covers sharpening apparatus, only exposes taper and cuts the insertion mouth that cuts cavity.Pencil bits of cutting out when cutting enter the cylindrical cavity of dress pencil bits from columniform hole, when removing the pencil bits, unplug the sharpening apparatus lid, the pencil bits can be removed from the pencil bits and mouthful be poured out, and then cover back sharpening apparatus and cover.During without sharpening apparatus, clog the sharpening apparatus tops, prevent that the pencil bits from leaking with plug.The lower body part of column type is a cap, during without propelling pencil, cap can be enclosed within on the propelling pencil penholder.
The effect that the utility model is useful is, cuts and uses not frangibility of, pencil-lead quick than the propelling pencil pencil-lead of lead bullion pen core, and is simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that propelling pencil sharpening apparatus small blade composition is cut the structure chart that cuts cavity.
Fig. 2 is the structure chart of propelling pencil sharpening apparatus.
Fig. 3 is the vertical section structural map of propelling pencil sharpening apparatus embodiment.
Among the figure: 1. plug, 2. sharpening apparatus lid, the 3. main body top entity of column type, 4. small blade, 5. columniform hole, the 6. cylindrical cavity of dress pencil bits, 7. the pencil bits are removed mouthful, 8. cap, 9. propelling pencil pencil-lead, 10. propelling pencil,
The specific embodiment
In Fig. 1,4 (4) small blade knife edge one end end points are got together, and per two pairs of knifes edge are formed the V font, the knife edge in opposite directions, become symmetric configuration, the knife edge is formed pinnacle taper down and is cut and cut cavity, and it is partly big or small identical that the taper nib than the lead bullion pen core that cuts cavity size and cut is cut in taper.
In Fig. 2, the body portion of column type separate be sharpening apparatus partly, (8) cap partly.(3) the entity center, main body top of column type has (5) columniform hole, 4 (4) small blade knife edge one end end points are got together, per two pairs of knifes edge are formed the V font, the knife edge in opposite directions, become symmetric configuration, be fixed in the main body top entity of (3) column type, article four, the knife edge is formed pinnacle taper down and is cut and cut cavity in (3) columniform hole, the taper nib that cuts cavity size and the pencil-lead of having cut is cut in taper, and partly size is identical, cut and cut cavity and when rotating when the pencil-lead of propelling pencil inserts taper, (4) small blade cutter peak and pencil-lead are cut the vertical chamfer degree of cutting that is rotated into that cuts partly.Propelling pencil is done the circumference rotation or come back rotation, just can finish cutting of pencil-lead cut.Pencil-lead is cut and cut the pressure that partly is subjected to from 4 directions of (4) 4 blade knifes edge in the space during rotation, stress balance, and the place that propelling pencil contacts with sharpening apparatus is few, just pencil-lead and (4) four knife edge linearities of small blade contacts, pencil-lead has its swing space among a small circle, so when propelling pencil rotated, pencil-lead is frangibility not, article 4, the knife edge is cut pencil-lead simultaneously and is cut, and pen core is cut sooner.(2) the sharpening apparatus lid partly covers sharpening apparatus, only exposes taper and cuts the insertion mouth that cuts cavity.Pencil bits of being cut out when cutting enter the cylindrical cavity of (6) dress pencil bits from (3) columniform hole, when removing the pencil bits, when unpluging (2) sharpening apparatus lid, the pencil bits can be removed from (7) pencil bits and mouthful be poured out, and then cover back (2) sharpening apparatus and cover.During without sharpening apparatus, clog (2) sharpening apparatus tops, prevent that the pencil bits from leaking with (1) plug.The lower body part of column type is (8) cap, during without propelling pencil, (8) cap can be enclosed within on the propelling pencil penholder.
