Abstract
A pencil sharpener for a card filling pencil comprises a base; a fixing blade and a conical pencil guide groove are arranged on the base; the top end of the fixing blade keeps a certain distance with the central axis of the conical pencil guide groove; a gear with an inserting hole is arranged in the base; the inserting hole of the gear with the inserting hole is arranged at the large end of the conical pencil guide groove; a pair of round gears meshed with the gear with the inserting hole are symmetrically arranged at the two sides of the gear with the inserting hole; and a movable blade is fixedly arranged on the inner side surface of each round gear. Due to the pencil sharpener for the card filling pencil, which is provided by the utility model, a flat duckbilled pencil lead can be sharpened to meet the requirement of the card filling pencil.
Description
Technical field
The utility model relates to a kind of stationery, especially a kind ofly can the card-coating pencil that pencil cuts flat duck lead for retractable pencil be used pencil sharpener.
Background technology
Pencil sharpener is the instrument that often uses during people learn, and it is uniform and smooth that traditional pencil sharpener only can be cut out wooden covering, and lead for retractable pencil is the pointed pencil of awl.But in examination now, need use the card-coating pencil that lead for retractable pencil is flat duck, traditional pencil sharpener can't satisfy.
Summary of the invention
The utility model technical problem to be solved provides a kind of card-coating pencil and uses pencil sharpener, can cut out flat duck lead for retractable pencil, satisfies the needs of card-coating pencil.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of card-coating pencil is used pencil sharpener; Comprise pedestal, pedestal is provided with ledger-plate and taper pencil guide groove, and the central axis of ledger-plate top and taper pencil guide groove is at a distance of certain distance; Band jack gear is installed in the pedestal; The jack of band jack gear is positioned at the stub end of taper pencil guide groove, the bilateral symmetry of band jack gear be provided with a pair of be with the jack gear circular gear of interlock mutually, the medial surface of circular gear is fixedly connected with cutting blade.
The regular hexagon of jack internal diameter for matching of band jack gear with positive six prismatic pencils.
The radius of circular gear is half the for the band jack outside diameter of gear.
The length of the shaft portion of cutting blade is than the long 2mm of length of taper pencil guide groove, and cutting blade is curved near the part of the jack of band jack gear, and the width of arch section be able to cut the graphite lead for retractable pencil with the knife edge near the central axis of taper pencil guide groove and be as the criterion.
The central axis of ledger-plate top and taper pencil guide groove is at a distance of 1.5mm.
The card-coating pencil that the utility model provides is used pencil sharpener; Because the central axis of ledger-plate top and taper pencil guide groove makes ledger-plate can cut the wooden covering of pencil, and does not damage the graphite lead for retractable pencil at a distance of certain distance; The jack that utilizes the rotation of pencil will drive the jack gear again rotates thereupon; Then drive cutting blade through circular gear and rotate, make the cutting blade knife edge periodically away from near the graphite lead for retractable pencil, can cut graphite lead for retractable pencil symmetric part; Can cut out flat duck lead for retractable pencil, satisfy the needs of card-coating pencil; The radius of circular gear is half the for the band jack outside diameter of gear, can be known by circumference formula L=2 Π R, and band jack gear revolution is crossed 180 degree; Circular gear just rotates a week; Be the moving half-turn of pencil revolution, cutting blade just to the cutting of graphite lead for retractable pencil has once been guaranteed the symmetry of cutting.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sketch map of the utility model band jack gear.
The specific embodiment
As depicted in figs. 1 and 2; The utility model comprises pedestal 1; Pedestal is provided with ledger-plate 2 and taper pencil guide groove 4, and band jack gear 3 is installed in the pedestal 1, and the jack of band jack gear 3 is positioned at the stub end of taper pencil guide groove 4; The bilateral symmetry of band jack gear 3 be provided with a pair of be with jack gear 3 circular gear 5 of interlock mutually, the medial surface of circular gear 5 is fixedly connected with cutting blade 6.
The regular hexagon of jack internal diameter for matching of band jack gear 3 with positive six prismatic pencils.
The radius of circular gear 5 is half the for band jack gear 3 external diameters.
The length of the shaft portion of cutting blade 6 is than the long 2mm of length of taper pencil guide groove 4; Cutting blade 6 is curved near the part of the jack of band jack gear 3, and the width of arch section be able to cut the graphite lead for retractable pencil with the knife edge near the central axis of taper pencil guide groove 4 and be as the criterion.
During use, pencil is inserted in the jack of band jack gear 3, gently rotation pencil; At first by the wooden covering of ledger-plate 2 cutting pencils, expose the graphite lead for retractable pencil, the jack that utilizes the rotation of pencil will drive jack gear 3 then rotates thereupon; Driving cutting blade 6 through circular gear 5 rotates; Make cutting blade 6 knifes edge periodically away from near the graphite lead for retractable pencil, can cut graphite lead for retractable pencil symmetric part, can cut out flat duck lead for retractable pencil.
When for the first time inserting pencil and cutting; Because the part shear action of cutting blade 6, be equivalent to select the privileged site of pencil cutting, so after extracting pencil out jack; If it is rethink cutting, consistent in the time of should keeping pencil to insert with the first time when then inserting with the relative position of band jack gear 3.
