Description
Technical field
The invention belongs to stationery sports goods technical field, and in particular to a kind of penknife for cutting six prismatic tip of a pencils.
Background technology
Pencil be people it is indispensable in daily life write, draw, the instrument of the aspect such as full-filling machine-read card.According to
Specific application target, has certain requirement to the shape of pencil-lead.For example, sketch drawing hooks line uses a diameter of 0.5mm-
The pen core of 1mm, full-filling machine-read card using square pen core 2mm wide, put down and needed when applying broader pen core contact in drawing by large area
Face.General penknife can only cut out conical pen core, it is impossible to meet the demand of above multiple use.At present specifically designed for full-filling
The penknife of machine-read card invention can only cut out unitary function, meet the pen core of full-filling machine-read card demand, such as Application No.
201510116056.8 patent.Another solution is to release the pencil of various different shape pen cores, and this can cause to disappear
The person of expense buys branched pencil, is unfavorable for the efficient utilization of resource, while also bad management.
The content of the invention
The present invention provides a kind of penknife for cutting six prismatic tip of a pencils, to solve the pencil-lead that current penknife cuts out
The problem of various use demands cannot be met.

Inverted trapezoidal blade 301 on face, moves, the inverted trapezoidal that pliers 402 is fixed on other faces for promoting the blade to make forward-reverse
Blade, for making forward-reverse motion on the line of the blade.
Compared with existing pencil sharpener, the cutting mechanism 3 of the penknife that the present embodiment is provided is arranged in cylinder inner casing 2,
Cutting mechanism 3 includes six inverted trapezoidal blades 301, blade holders 303, and six inverted trapezoidal blades 301 are with regular hexagon
Shape is evenly distributed, and has a fixed mount through hole 305 in each blade holder 303, has per a piece of tail end of inverted trapezoidal blade 301
Blade round bar structure 304, makes blade insert in blade holder 303 and is connected, and can be revolved by pivot of base axis
Turn, every insert tip has a blade positioning hole 302, for being fixed with pincerlike power transmission component 4.Six inverted trapezoidal blades
301 every blade is in " T " word moulding, pencil effectively can be needed into the quick cutting in removal part, more laborsaving, and cutting
Under pen bits will not fly around, directly spilt by through hole 210, be convenient to clean, the attractive in appearance of environment is not influenceed.
In order that penknife can be applied to the pencil of cutting different shaping, it is preferable that the cutting mechanism 3 in the present embodiment
The motion opened and close up can be done, blade deployed condition 8 is in when the penknife is not used, a pencil is put into through hole 210
In, shell 1 is gently held with hand, the pliers 402 of pincerlike power transmission component 4 is subject to the passage of the inwall of shell 1 inwardly slightly to close up, is fixed on
Four inverted trapezoidal blades 301 on pliers 402 are driven the slight axis to cutter assembly and are polymerized, while being connected to sliding block 406
On blade and the blade that is connected on pliers 402 slightly close up to the axis direction of cutting mechanism 3, by inverted trapezoidal blade 301
Tip portion is embedded in pencil and pencil is fixed.
Hold with a firm grip shell 1, sliding block 406 is subject to the extruding of the inwall of shell 1 to move inward, pliers 402 and sliding block 406 are subject to shell
1 inwall closes up in being pressed against, and the blade being connected on sliding block 406 and the blade being connected on pliers 402 are simultaneously to cutting mechanism 3
Axis direction close up.Now, six inverted trapezoidal blades 301 of expansion become closed configuration 7, six ribs needed for forming tip of a pencil
Clevis angle.Pencil and penknife are pulled round about, pencil is cut, repeat this process, pencil can cut
Six prismatic tip of a pencils 5 are cut out, and produces wood chip 6.The mode of this sharpening pencil is more laborsaving than the mode of Propelling pencil with sharpener in cap.
Plot Work person 1mm, 2mm and realizes that large area is flat and applies when mapping, it is necessary to draw the lines of different thicknesses degree, such as
More than 4mm lines, by control it is different hold an angle, allow six prismatic tip of a pencils 5 different surfaces contact drawing plane just
Object above can be realized.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
