Abstract
This pencil-sharpening device, comprise there is cavity housing, be positioned at housing for the blade of sharpening pencil and the cutting blade clip clamping fixed blade, housing upper end is provided with cutting entrance, in housing cavity, the left and right sides is tiltedly installed with cutting blade clip chute, and cutting blade clip two Slideslip is arranged in cutting blade clip chute.By adjusting device drive cutting blade clip along cutting blade clip chute move up and down thus realize adjustable blade from cutting entrance expose Len req, the protruding blade that also can drive of blade can be driven inwardly to retract, achieve bidirectional modulation.Because cutting blade clip slides along the slide construction that cutting blade clip chute is unique only, therefore blade remains constant in adjustment process medium dip angle, guarantees good cutting effect.During use, be fixed to by this pencil-sharpening device on desk or be fixed on object with a hand, hand-held pencil repeatedly slips over the cutting edge of blade on housing, can realize the effect sharpened a pencil.Frame for movement is simple simultaneously, is convenient to manufacture and assembling.
Description
Technical field
The utility model relates to a kind of stationery, is specifically related to a kind of pencil-sharpening device.
Background technology
As everyone knows, pencil is the requisite stationery of colony such as numerous students, technical staff, artist in routine work life, but to sharpen a pencil be use requisite link in pencil.Use the manual inefficiency that sharpens a pencil of pocket knife, lead powder wood chip is scattered contaminated environment, and the instrument of sharpening a pencil has a lot in the market, but pencil all can only be whittled into the short taper profile shape being suitable for writing by them, and that length and thin pencil stub that are suitable for sketch drawing needs can not be cut out.
The utility model patent of CN202879076U discloses a kind of pencil-sharpening device, but when it exists adjustable blade cutting edge, the problem that cutting edge can only be stretched and can not shrink back, also exists the drawback of producing and assembling inconvenience simultaneously.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of pencil-sharpening device using common blade of carving knife can cut elongated nib.
The utility model overcomes the technical scheme that its technical problem adopts:
This pencil-sharpening device, comprise there is cavity housing, be positioned at housing for the blade of sharpening pencil and the cutting blade clip clamping fixed blade, described housing upper end is provided with cutting entrance, in described housing cavity, the left and right sides is tiltedly installed with cutting blade clip chute, described cutting blade clip two Slideslip is arranged in cutting blade clip chute, described blade stretches out certain length from cutting entrance, described cutting blade clip lower end is provided with guideway, adjusting device is connected to guideway, for the adjustment of cutting edge overhang from cutting entrance of blade.
Above-mentioned adjusting device is comprised adjustable plate, is arranged at the screw of adjustable plate lower end and is horizontally rotated the screw rod be installed on housing by snap ring, and described adjustable plate upper end is by guideway and cutting blade clip lower end is oblique is slidably connected, and described screw rod is combined in screw.
In order to improve the cutting effect of pencil, above-mentioned housing is provided with along the direction perpendicular to blade the pencil chute concaved, and the width of described pencil chute is greater than pencil diameter.
In order to make this pencil-sharpening device handsome in appearance on the whole, above-mentioned screw rod is sunk screw, described housing is provided with corresponding for holding the counter sink of sunk screw head.
The beneficial effects of the utility model are: by adjusting device drive cutting blade clip along cutting blade clip chute move up and down thus realize adjustable blade from cutting entrance expose Len req, the protruding blade that also can drive of blade can be driven inwardly to retract, achieve bidirectional modulation.Because cutting blade clip slides along the slide construction that cutting blade clip chute is unique only, therefore cutting blade clip remains constant in adjustment process medium dip angle, and also, blade also by maintenance one stationary state, guarantees good cutting effect.During use, be fixed to by this pencil-sharpening device on desk or be fixed on object with a hand, hand-held pencil repeatedly slips over the cutting edge of blade on housing, can realize the effect sharpened a pencil.Frame for movement is simple simultaneously, is convenient to manufacture and assembling.

Detailed description of the invention
Be described further below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 pairs of the utility model.
This pencil-sharpening device, comprise there is cavity housing 1, be positioned at housing 1 for the blade 4 of sharpening pencil and the cutting blade clip 2 clamping fixed blade 4, housing 1 upper end is provided with cuts entrance 3, in housing 1 inner chamber, the left and right sides is tiltedly installed with cutting blade clip chute 8, cutting blade clip 2 liang of Slideslips are arranged in cutting blade clip chute 8, blade 4 stretches out certain length from cutting entrance 3, cutting blade clip 2 lower end is provided with guideway 10, adjusting device is connected to guideway 10, for the adjustment of cutting edge overhang from cutting entrance 3 of blade 4.By adjusting device drive cutting blade clip 2 along cutting blade clip chute 8 move up and down thus realize adjustable blade 4 from cutting entrance 3 expose Len req, the protruding blade 4 that also can drive of blade 4 can be driven inwardly to retract, achieve bidirectional modulation.Because cutting blade clip 2 slides along the slide construction that cutting blade clip chute 8 is unique only, therefore blade 4 remains constant in adjustment process medium dip angle, and also, blade also by maintenance one stationary state, guarantees good cutting effect.During use, be fixed to by this pencil-sharpening device on desk or be fixed on object with a hand, hand-held pencil repeatedly slips over the cutting edge of blade 4 on housing, can realize the effect sharpened a pencil.Frame for movement is simple simultaneously, is convenient to manufacture and assembling.
The structure of guideway is not limited to the parcel slot type in accompanying drawing 2, and other structure example such as hitching post-chute-type is also effect same.
Adjusting device can be following structure, it is comprised adjustable plate 5, is arranged at the screw of adjustable plate 5 lower end and is horizontally rotated the screw rod be installed on housing 1 by snap ring 7, adjustable plate 5 upper end is slidably connected with cutting blade clip 2 lower end is oblique by guideway 10, and screw rod is combined in screw.Pass through rotating screw bolt, it can drive adjustable plate 5 to move along the axis direction of screw rod, because adjustable plate 5 and cutting blade clip 2 are that guideway 10 by tilting is slidably connected, therefore when adjustable plate 5 horizontal movement, it drives cutting blade clip 2 to slide up and down along cutting blade clip chute 8 simultaneously, thus adjustable blade 4 is from cutting the length exposed entrance 3, simply easy to adjust.
Further, above-mentioned housing 1 can be provided with along the direction perpendicular to blade 4 the pencil chute 9 concaved, and the width of pencil chute 9 is greater than pencil diameter.When sharpening a pencil, pencil can be placed in pencil chute 9, and two stiles of pencil chute 9 can play the effect guiding pencil, pencil is moved along the direction perpendicular to blade 4 all the time in working angles, thus reaches better cutting effect.
Further, above-mentioned screw rod is sunk screw 6, housing 1 is provided with corresponding for holding the counter sink of sunk screw head.The head of screw of sunk screw 6 is placed in counter sink, because the extension elongation of blade 4 does not need frequent adjustment, so adopt this kind of structure can make the moulded attractive in appearance of this pencil-sharpening device, does not have lofty sense.
