Description
Technical field
The utility model relates to a kind of cutter hub, especially relates to a kind of cutter hub of pencil sharpener.
Background technology
Pencil sharpener is a kind of common stationery, cuts wooden carbon pencil for volume.Existing pencil sharpener generally includes shell, be installed in front connector and rear joint on shell, be located at the rotating knife rest between front connector and rear joint, the cutter hub be contained in knife rest, knife rest has an outer shaft by rear joint through shell, 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 the driving mechanism driving rocking arm to rotate, and front connector offers a pencil hole.One end of pencil is inserted in cutter hub from pencil hole, rotates rocking arm, cutter hub roll cutting pencil.
Cutter hub is as the core component of pencil sharpener, mainly comprise cutter hub main body and screw blade, cutter hub main body is fixedly arranged in front connector, cutter hub body interior is formed with one for holding the conical mesopore of pencil one end, conical mesopore is through hole, the sidewall of conical mesopore is provided with a spirality chip removal seam, screw blade is positioned at the top of conical mesopore, screw blade has a spiral cutting edge, the bottom of cutter hub main body arranges square chip-removal hole, and chip-removal hole is positioned at the little head end place of conical mesopore and communicates with the little head end of conical mesopore.
But, there is following problem in existing cutter hub: conical mesopore is the through hole of horizontally set, after ensureing pencil taper to certain diameter, stop volume cutting, mainly at present in the little head end of conical mesopore, a cylindrical bar is installed again, when tip of a pencil volume is cut to when contacting with cylindrical bar, pencil starts idle running, is no longer cut by volume, also need thus process and cylindrical bar is installed, production technology more complicated outside cutter hub main body; Two, in order to avoid destroying the structure of conical mesopore, the width of the chip-removal hole of the bottom of cutter hub main body can not exceed the width of the little head end of conical mesopore, the size of chip-removal hole is usually less, cause chip removal effect poor thus, and make mould in cutter hub main body production process and demoulding difficulty is all larger.
Utility model content
One of technical problem to be solved in the utility model is to provide a kind of cutter hub of pencil sharpener, the tail end of the cutter hub main body of this cutter hub has been wholely set resistance feed arrangement, conical mesopore extends to the cut-off of resistance feed arrangement from the head end of cutter hub main body, because cutter hub main body and resistance feed arrangement are integrally formed, production technology is fairly simple.
Two of technical problem to be solved in the utility model is to provide a kind of cutter hub of pencil sharpener, the side of the conical mesopore of this cutter hub is provided with the chip area be communicated with conical mesopore, chip area extends to the tail end of cutter hub main body, the size of chip area can be relatively large thus, chip removal effect is better, and makes mould in cutter hub main body production process and the demoulding is easy.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of cutter hub of pencil sharpener, comprise cutter hub main body and screw blade, described cutter hub body interior is formed with one for holding the conical mesopore of pencil one end, the sidewall of described conical mesopore is provided with spirality chip removal seam, described screw blade is positioned at the top of described conical mesopore and its blade stitches extension along spirality chip removal, the afterbody of described cutter hub main body has been wholely set resistance feed arrangement, described conical mesopore ends after the head end of described cutter hub main body extends to described resistance feed arrangement, the little head end of described conical mesopore is closed by described resistance feed arrangement, described cutter hub main body arranges chip area, described chip area is communicated with described conical mesopore, described chip area is positioned at the side of described conical mesopore and extends to the tail end of described cutter hub main body.
The material of described cutter hub main body and described resistance feed arrangement is plastics, and it is one-body molded that described cutter hub main body and described resistance feed arrangement pass through Shooting Technique.
Described spirality chip removal seam covers the quadrant cone contour exceeding described conical mesopore, and the blade of described screw blade is spiral cutting edge, and described spiral cutting edge covers the circular cone contour exceeding quadrant taper mesopore.
Compared with prior art, the utility model has the advantage of by being wholely set resistance feed arrangement at the afterbody of cutter hub main body, conical mesopore ends after the head end of cutter hub main body extends to resistance feed arrangement, cutter hub main body and resistance feed arrangement can be integrally formed thus, and production technology is fairly simple; Simultaneously, cutter hub main body arranges chip area, chip area is communicated with conical mesopore, chip area is positioned at the side of conical mesopore and extends to the tail end of cutter hub main body, the impact of chip area on conical mesopore is less, the size of chip area can be relatively large, and chip removal effect is better, and make mould in cutter hub main body production process and the demoulding is easy.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Embodiment: as shown in Figure 1 to 4, a kind of cutter hub of pencil sharpener, comprise cutter hub main body 1 and screw blade 2, cutter hub main body 1 inside is formed with one for holding the conical mesopore 6 of pencil one end, the sidewall of conical mesopore 6 is provided with spirality chip removal seam 3, screw blade 2 is positioned at the top of conical mesopore 6 and its blade stitches 3 extensions along spirality chip removal, the afterbody 11 of cutter hub main body 1 has been wholely set resistance feed arrangement 4, conical mesopore ends after the head end of cutter hub main body 1 extends to resistance feed arrangement 4, the little head end of conical mesopore is hindered feed arrangement 4 and is closed, cutter hub main body 1 is arranged chip area 5, chip area 5 is communicated with conical mesopore 6, chip area 5 is positioned at the side of conical mesopore 6 and extends to the tail end 12 of cutter hub main body 1.
In the present embodiment, the material of cutter hub main body 1 and resistance feed arrangement 4 is plastics, and it is one-body molded that cutter hub main body 1 and resistance feed arrangement 4 pass through Shooting Technique.
In the present embodiment, spirality chip removal seam 3 covers the quadrant cone contour exceeding conical mesopore, and the blade of screw blade 2 is spiral cutting edge, and spiral cutting edge covers and exceedes the circular cone contour of quadrant taper mesopore, and to cut effect better for volume thus.
When use has the pencil sharpener of cutter hub of the present utility model, one end of pencil is inserted in conical mesopore 6 from the pencil hole of pencil sharpener, one end of screw blade 2 roll cutting pencil, cut in process at volume, the nib of pencil moves forward, when the nib of pencil moves to the little head end of conical mesopore 6, owing to hindering the stop of feed arrangement 4, pencil produces idle running, and screw blade 2 no longer carries out volume to pencil and cuts, and reduces pencil thus and excessively rolls up the waste of cutting and causing.
