Abstract
The utility model discloses a pencil lead rolling knife; including a box cover, a knife body, a blade and a chip storing box; the knife body is arranged on the box cover, an elastic part is arranged between one end of the knife body along the axial direction and the bottom edge of the box cover; during cutting, and the pencil lead is not likely to be crookedly cut or snapped; the pencil lead rolling knife can cut the pencil lead with a diameter of over 1.5 mm more conveniently and has simple structure and convenient and labor-saving usage.
Description
Technical field:
The utility model discloses a kind of pencil lead with rolling up cutter, particularly a kind of pencil lead volume core cutter.
Background technology:
We know, pencil is big, in, requisite writing implement in pupil and people's routine work and the study, wooden pencil miscellaneous, propelling pencil, environment protection type pencil is numerous, the apparatus of existing cutting pencil occurs in a large number, as China Patent No. is that ZL92242499.9 " propelling pencil pencil sharpener " has a little taper hole on housing, chip area is established in the side of little taper hole, and side plate, and blade is housed on the side plate, this volume cutter only depends on pencil to rotate, and the remaining part of volume cutter is motionless, and is time-consuming when pencil sharpener sharpens a pencil, effort, and pen core very easily fractures during roll cutting pencil, particularly difficult especially to the pencil cutting of lead for retractable pencil more than 1.5mm, and can not cut pure lead for retractable pencil, make the pencil of cutting cause waste.
The utility model content: the purpose of this utility model will provide a kind of pencil lead volume cutter exactly, its cutting pencil lead cutting evenly, the quality of cutting lead for retractable pencil is good and can not fracture, convenient and swift saving time is laborsaving.
The technical solution of the utility model is achieved like this, and it comprises lid, cutter hub, and blade, scrap storage box body are established cutter hub on lid, and in axial direction cutter hub is provided with elastic component between the base of end of lid base direction and lid.
Establish the pencil fairlead on lid, establish a conical hole on the pencil fairlead, a described taper shape center, hole is consistent with lead for retractable pencil tapered hole center on the cutter hub.
Be provided with slideway shelf on lid, cutter hub is located on the slideway shelf, establishes elastic component between the slideway shelf base on cutter hub one end and the lid.
The lid activity is placed on the scrap storage box body.
Have examination core hole on lid, described examination core hole axial length is consistent with cutting lead for retractable pencil length.
Described elastomer is a spring.
When the utility model adopted said structure cutting pencil, convenient and swift, it established the pencil fairlead on lid, and cutter hub, and blade is housed on cutter hub, and the center line in a conical hole is consistent with the lead for retractable pencil degree centerline hole on the cutter hub on the fairlead.And the axial direction along pencil is provided with spring between the bottom of cutter hub and lid, like this when pencil insertion pencil fairlead conical bore cuts pencil-lead, the pencil fairlead can rotate freely on lid, under the effect of spring force, cutter hub constantly advances, automatically evenly cut lead for retractable pencil, because askew fractureing can not cut with the consistent lead for retractable pencil in center, cutter hub lead for retractable pencil hole in the fairlead center.To the more convenient cutting of the lead for retractable pencil of lead for retractable pencil more than 1.5mm, simple in structure, easy to use, laborsaving.
Description of drawings:
Fig. 1 is the utility model structural profile schematic diagram.
Among the figure: 1 lid, 2 cutter hubs, 3 blades, 4 screws, 5 slideway shelfs, 6 elastic components, 7 scrap storage box bodies, 8 pencil fairleads, 9 examination core holes, 10 pencils, 11 bases.
The specific embodiment:
Lid 1 active card is contained on the scrap storage box body 7 as shown in Figure 1, pencil fairlead 8 and cutter hub 2 are installed on the lid 1, pencil fairlead 8 is movably arranged on the lid 1 and can rotates freely, cutter hub 2 also can be installed on the slideway shelf 5, present embodiment cutter hub 2 is installed on the slideway shelf 5, slideway shelf 5 then is movably arranged on the lid 1, base 11 overlaids of the base of slideway shelf 5 and lid 1, on pencil fairlead 8, offer and the corresponding to taper shape of pencil 10 a profiles hole, cutting lead for retractable pencil tapered hole center line overlaid on the center line in a described taper shape hole and the cutter hub 2 coincide consistent, and have open slot on the cutter hub 2 on the tapered hole, blade 3 is installed on the open slot on the blade 3 by screw 4, one end and the pencil fairlead 8 of cutter hub 2 match, cutter hub 2 other ends are provided with an elastic component 6 along between the base 11 of lead for retractable pencil axial direction and lid 2, present embodiment elastic component 6 is a spring, an end that is elastic component 6 withstands on cutter hub 2 one ends along the axial direction of lead for retractable pencil, the other end withstands on the base 11 of lid 1, and present embodiment cutter hub 2 is contained on the slideway shelf 5, and slideway shelf 5 is to be contained on the lid 1, thereby elastic component 6 one ends are to withstand on that the other end then withstands on the base of slideway shelf 5 on the cutter hub 2, have examination core hole 9 on pencil lid 1, the degree of depth in examination core hole 9 is consistent with lead for retractable pencil tapered hole length on the cutter hub 2.
The operation principle and the course of work are as follows: describe with present embodiment, lid 1 is installed on the scrap storage box body 7, slideway shelf 5 is contained on the lid 1 by interference fit, pencil fairlead 8 is installed on the lid 1, cutter hub 2 is installed on the slideway shelf 5, cutter hub 2 one ends withstand the end that pencil fairlead 8 other ends then withstand elastic component 6, elastic component 6 withstands on the base of slideway shelf 5 along the axial direction of pencil 10 and lead for retractable pencil, when sharpening a pencil lead for retractable pencil, be close to mutually and relative fixed inserting the taper shape of pencil 10 from pencil fairlead 8 hole until the circular cone inclined-plane of pencil 10 and the inclined-plane of pencil fairlead 8, at this moment the distance of cutter hub 2 pushers and the need equal in length of cutting lead for retractable pencil, rotation pencil 10 and pencil fairlead 8, blade 3 on the cutter hub 2 promptly cuts the lead for retractable pencil on the pencil 10, in working angles, under the elastic force effect of elastic component 6, constantly automatically, evenly advance cutter hub 2 cutting lead for retractable pencils, make the lead for retractable pencil of pencil 10 just be easy to obtain cutting and frangibility not, up to the lead for retractable pencil on the pencil 10 is cut, especially be fit to the above pencil volume cutter cutting of lead for retractable pencil 1.5mm.
