The utility model provides a pencil sharpener for sharpening a pencil into a flat head in a longitudinal feeding and grinding manner. The pencil sharpener comprises a shell, wherein the pencil sharpener is characterized in that a pencil fixing unit is arranged at the top of the housing; a pair of cylindrical grinding wheel cutters is fixed on the inner wall of the housing and particularly mounted in a way that the cylindrical grinding wheel cutters are parallel to each other with a gap formed between the cylindrical grinding wheel cutters; gears are mounted at two ends of the cylindrical grinding wheel cutters and engaged with each other; a crank is mounted at one end of one cylindrical grinding wheel cutter; a rotary sharpener for sharpening a pencil holder is mounted at the lower part of the housing and comprises a sharpener frame, a folding blade, and a conical guide slot and a cylindrical guide slot which are in front-and-back connection; and the folding blade is tangential to the openings of the conical guide slot and cylindrical guide slot. By arranging the two cylindrical grinding wheel cutters, the pencil sharpener of the utility model is capable of sharpening the pencil into the flat head; by sharpening the pencil holder and pencil head respectively, the utility model can prevent the lead from being broken; by arranging the rotary sharpener for sharpening the pencil into a sharp head, the utility model can provide options for sharpeners; and a scrap collecting box can recycle the pencil scrap on a timely basis.
Description
Technical field
The utility model provides a kind of length feed grinding formula to cut flat pencil-knife.
Background technology
At present, the pencil-knife great majority that we see are rotary cut formula pencil-knifes, the basic structure of this pencil-knife is made up of housing, blade, guide groove, on the housing knife rest blade is installed, guide groove is to be formed by the cone cavity, and the opening of guide groove and blade keep certain position relation, when practical, columned pencil advances along the guide groove rotation, is become cylinder by blade cut, and lead for retractable pencil also is cut coning.The lead for retractable pencil that this cutting way is cut out can only be conical, and lead for retractable pencil is not only thin but also sharp, can not satisfy the demand of many aspects, needs the pen core of flat with pencil as blot out computer read card.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of above-mentioned defective that solved is provided, can cut out the flat nib, save the used time that sharpens a pencil, length feed grinding formula simple in structure, easy to use cuts flat pencil-knife.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of length feed grinding formula is cut flat pencil-knife, comprise housing, it is characterized in that: case top is provided with the pencil fixture, be fixed with a pair of cylinder emery wheel cutter on the inner walls, the parallel installation of cylinder emery wheel cutter, between two cylinder emery wheel cutters the slit is arranged, gear is equipped with at cylinder emery wheel cutter two ends, the gear at two cylinder emery wheel cutter two ends is meshing with each other, one end of one of them cylinder emery wheel cutter is equipped with wind, lower part of frame is equipped with cuts the penholder pencil sharpener, cut penholder and comprise knife rest with pencil sharpener, the conical guide groove that the jack knife sheet links to each other with front and back, cylindrical guide groove, jack knife sheet and conical guide groove, the opening of cylindrical guide groove is tangent.
Described pencil fixture comprises pencil holder, has the fixedly chuck of pencil supported hole, housing central authorities have and corresponding hole, pencil supported hole position, fixedly be evenly equipped with a plurality of guide rods on the chuck, case top is provided with and the corresponding guide groove in guide rod position, be with spring on the guide rod, guide rod inserts in the guide groove.
The described penholder of cutting is equipped with the head pencil sharpener of fining away with pencil sharpener one side, and the head of fining away is known rotary cut formula pencil sharpener with pencil sharpener.
Described housing bottom is provided with the pencil bits and collects box.
The whole process that sharpens a pencil is carried out in two steps:
(1) cuts penholder: timber is pruned in pencil sharpener cutting penholder, exposed the cylindrical nib of suitable length, be generally 3.5mm～4mm; (2) earlier fixedly chuck upwards pull out a segment distance, pinch out pencil holder, the pencil that will expose cylindrical nib injects fixedly in the chuck by the pencil supported hole, when the pencil nib is inserted between two cylinder emery wheel cutters, unclamp pencil holder and fixing chuck, shake wind then, driving the cylinder emery wheel cutter rotates, meanwhile fixedly chuck drives pencil length feed between the cylinder emery wheel cutter under spring action, up to nib is whittled into flat, pinch out pencil holder, take out pencil.
The beneficial effect that the utility model had is: length feed grinding formula is cut flat pencil-knife owing to be provided with two cylinder emery wheel cutters, can cut out the flat nib; With penholder and separately cutting of nib, neither easily broken lead can easily be finished the cutwork of flat nib again, makes working angles more reliable; The head of fining away is set uses pencil sharpener, can freely select the type of pencil sharpener according to individual demand; Pencil bits are set collect box, the pencil bits that can produce when sharpening a pencil in time reclaim.
