Abstract

The utility model relates to a lead pencil knife, in particular to a lead pencil knife with a plurality of blades arranged in an inclined manner. The utility model comprises a tool post and blades and is characterized in that a pencil sharpening unit of the tool post is arranged with at least two pieces of inclined pencil sharpening blades, with the blades arranged on the tool post in an inclined manner, the tool post is provided with two or one pencil sharpening unit, and the tool post is also provided with a single straight cutting edge straight blade. The utility model adopts a structure of a plurality of blades which are arranged in an inclined manner, thereby solving the contrast between large cutting area and large cutting resistance of a single piece of blade and further realizing a labor saving in a pencil sharpening. Furthermore, as the cutting edges of the blades are arranged in an inclined manner, the cutting edges may advance in a spiral manner and play a better cutting effect while compared with straight cutting edges.

Description

The multitool sheet is tiltedly arranged the Pencil planer cutter

Technical field

The utility model relates to the cutter that sharpens a pencil, and refers in particular to the multitool sheet and tiltedly arranges the Pencil planer cutter.

Background technology

Old-fashioned " a slice straight knife formula " penknife of Xiao Shouing in the market, because of not meeting the principle of timber wood grain lines, its shortcoming is obviously easily to see: the one, be not durable, and as long as blade is sharp a little inadequately, or the pencil wood grain was crossed slightly, and pine just at all can't be good with pencil sharper excessively.The 2nd, it is also very difficult good with pencil sharper that the pencil wood grain was crossed slightly pine.The 3rd, easily that pencil pen core volume is disconnected.In addition, some children are joyful because of the wood shavings of feeling to cut pen sometimes, just cut continuously, without a break a pencil sharper of newly buying got almost only surplus half sometimes, and this obviously is unfavorable for saving timber, is unfavorable for environmental protection.

Summary of the invention

The purpose of this utility model is improved and is innovated at the shortcoming that exists in the background technology and problem, provides a kind of simple in structure, easy for installation, easy to use, and the multitool sheet of long service life is tiltedly arranged the Pencil planer cutter.

The technical solution of the utility model is: the Pencil planer cutter of constructing the oblique arrangement architecture of a kind of multitool sheet, it comprises tool rest, blade, be characterized in that of tool rest cuts pens unit and arranges two at least and cut an oblique blade, wherein cut an oblique blade edge tilted be arranged on the tool rest, be provided with two on the tool rest and cut pens unit or one and cut pens unit, also comprise on the tool rest straight cutting edge list straight knife sheet is set.

The structure that the utility model adopts the multitool sheet tiltedly to arrange, it is big to solve the single blade area of cut, the contradiction that cutting resistance is big, it is more laborsaving when planing tool is cut, because blade cutting edge is an oblique arrangement, cutting edge can be cut into by screw, compresses into the shear action that more can bring into play cutting edge simultaneously than straight cutting edge.

The specific embodiment

By Fig. 1 to 3 as can be known, the utility model comprises tool rest, blade, be characterized in that of tool rest (2) cuts pens unit and arranges two at least and cut an oblique blade (1), be arranged on the tool rest (2) with wherein cutting an edge tilted of oblique blade (1), be provided with two on the tool rest (2) and cut pens unit or one and cut pens unit, also comprise on the tool rest (2) straight cutting edge list straight knife sheet (3) is set.

Oblique blade described in the utility model (1) can adopt three tiltedly structures of row, cuts pens unit by one and constitutes.Described oblique blade (1) can also adopt four tiltedly structures of row, also cuts pens unit by one and constitutes.Four oblique cuttves are installed method, and a slice tilts with opposite direction on the top, is convenient to cut pen core, also it can be installed on the back side, cuts pen core with two cuttves like this, and pen core is frangibility not.Described oblique blade (1) and straight knife sheet (3) can adopt the combining structure of cutting pens unit of cutting a pens unit or a straight knife sheet formation that is made of at least two oblique blades (1).New-type three oblique cutter formulas and an old-fashioned straight knife formula penknife can attach together together, so both can satisfy the user to the new product demand, unacceptable user's needs in the time of also can facing upward unification.The cutting edge of described oblique blade (1) can also adopt arcuate structure.As shown in Figure 4, the pencil that utilizes three straight swords to cut out should have corner angle, but considers only 1.3 centimeter length of the required length of cutting of pencil, and is both not obvious, can be not influential yet, and utilize three cuttves to cut pen, even angle mount not also can be cut well than a slice straight knife.As shown in Figure 5, the pen that utilizes three cambered blades to cut out, as long as arrangement is proper, the pen of cutting out is just straight too.The central authorities of described oblique blade (1) are provided with screw hole, with screw (4) blade are fixed on the tool rest (2).Old-fashioned " a slice straight knife formula " penknife, because of not meeting the principle of timber wood grain lines, many defectives are arranged, removing the sharp new cutter of the blade just bought can be with beyond the highest heavens several, as long as blade is sharp a little inadequately, or the pencil wood grain crossed slightly cross loose just at all can't pencil sharper is good, so, if adopt " three (or four) are the cutter formula tiltedly " penknife, just can solve the weak point of old-fashioned penknife, be well suited for children's use that pen can not cut by pupil and preschool class.

Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; do not breaking away under the preceding topic of the utility model design philosophy; engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
