Description
Technical field
The utility model relates to a kind of pencil sharpener cuts the stationery of use, especially has the single blade pencil sharpener about a kind of high efficiency, light weight.
Background technology
Hand-cranked pencil sharpener is a kind of common stationery, for volume, cuts wooden carbon pencil.Be illustrated in figure 6 a kind of existing hand-cranked pencil sharpener.It comprises a shell 9, in shell 9, accommodate a knife rest 91, be formed with a conical pencil accommodation hole in knife rest 91, pencil accommodation hole one side offers a slit, along slit, be installed with a columniform hobboing cutter 92, knife rest 91 other ends handle 93 that is threaded.The pencil accommodation hole that during use, pencil is inserted to knife rest 91 by shell 9 front cover holes, swinging handle 93 is with movable knife rack 91, by being fixed on the pinion of the moving hobboing cutter of shell 9 upper planetary gear astragals 92 one end, hobboing cutter 92 is rolled around pencil, realizes the cutting to pencil.Complete volume cut process after user pencil can be extracted out.
There is following shortcoming in this traditional hand-cranked pencil sharpener, and the first, a volume efficiency is low.Cylindrical hobbing 92 is line with pencil at slit place and contacts, and contact area is little, and user need to rotate a lot of circles could be to cutting effect to required volume.The second, hobboing cutter volume is large, and weight is large, and user carries inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of single blade pencil sharpener, and it has screw blade, and the contact area of screw blade and pencil is larger, therefore has higher volume and cuts efficiency.
Another technical problem to be solved in the utility model is to provide a kind of single blade pencil sharpener, and its blade itself is thin, lightweight, can effectively reduce the shared volume and weight of hobboing cutter, thereby person easy to use carries.
In order to solve the problems of the technologies described above, the utility model provides a kind of single blade pencil sharpener, and it comprises a shell, is installed with joint after a front connector and on shell.Between front connector and rear joint, be provided with a rotating knife rest.Knife rest has an outer shaft and passes shell by rear joint, in knife rest, accommodate a cutter hub, cutter hub is fixedly arranged in front connector, cutter hub inside is formed with one for holding the conical mesopore of pencil one end, is formed with the spiral row that a covering exceedes quadrant cone contour and cuts seam on the sidewall of conical mesopore.On cutter hub, be installed with a screw blade, screw blade has a spiral cutting edge, and spiral cutting edge is cut seam along row and extended the circular cone contour that covering exceedes quadrant taper mesopore.Shell is provided with a rocking arm, the outer shaft Joint of rocking arm and knife rest.The free end of rocking arm is provided with a rotating handle, offers a pencil hole in front connector.
The beneficial effect that the utility model brings is the efficiency that has improved pencil sharpener roll cutting pencil.Tradition hand-cranked pencil sharpener often needs to rotate volume that 10 circles left and right can reach to be cut effect pencil sharpener of the present utility model and rotates 3 circle left and right and just can reach, and has greatly promoted the efficiency sharpening a pencil.On the other hand, the round screw blade of monolithic has alleviated the weight and volume of traditional cylindrical hobboing cutter greatly, and more convenient user carries.

The specific embodiment
With reference to figure 1,2,3,4 and 5, it shows the preferred embodiment of a kind of single blade pencil sharpener of the utility model.This single blade pencil sharpener comprises a shell 10, is installed with joint 12 after a front connector 11 and on shell 10, is provided with a rotating knife rest 13 between front connector 11 and rear joint 12.At knife rest 13, have an outer shaft 131 and pass shell 10 by rear joint, accommodate a cutter hub 14 in knife rest 13, cutter hub 14 is fixedly arranged on front connector 11.Cutter hub 14 inside are formed with one for holding the conical mesopore 141 of pencil one end, be formed with the spirality row that a covering exceedes quadrant cone contour and cut seam 142 on the sidewall of conical mesopore 141.On cutter hub 14, be installed with a screw blade 15, screw blade 15 has a spiral cutting edge 151, and spiral cutting edge 151 is cut seam 142 along spirality row and extended, and covers the circular cone contour that exceedes quadrant taper mesopore 141.Shell 10 is provided with a rocking arm 16, and outer shaft 131 Joints of rocking arm 16 and knife rest 13 can make knife rest 13 rotate by rotating rocking arm 16.The free end of rocking arm 16 is provided with a rotating handle 161.In front connector 11, offer a pencil hole 111, pencil 20 can be inserted in the conical mesopore 141 of cutter hub 14 by the pencil hole 111 in front connector 11.The cone tip of conical mesopore 141 can be provided with a cylindrical bar 142, when the lead for retractable pencil 21 of pencil 20 touches cylindrical bar 142, being rotated further rocking arm 16 cutter hubs 14 will dally, screw blade 15 will no longer cut pencil 20, thereby can reduce, pencil excessively be rolled up and will be cut the waste causing.
In use, user can insert pencil 20 in shell 10, and pencil 20 is entered in the conical mesopore 141 of cutter hub 14 through the pencil hole 111 of front connector 11.Now user can rotate rocking arm 16 with the finger gripping handle 161 of stopping.Rocking arm 16 drives the outer shaft 131 being solid-located that knife rest 13 is rotated, and the screw blade 15 on knife rest 13 rotates with respect to pencil 20, and pencil 20 is cut.When the pen core 21 of pencil 20 is cut to length-specific, touch cylindrical bar 142, cutter hub 14 dallies, and pencil 20 cuts complete.
