Abstract
The utility model relates to the pencil of the obstructed head of a kind of lead for retractable pencil; frid A, frid B middle inside symmetry have core groove; lead for retractable pencil arranges in core groove; frid A and frid B is glued together; frid A, frid B cross section are semicircle; core slot length is less than frid A, frid B; frid A, frid B outer side covers varnish protective layer; frid A, frid B adopt log plane system to form; lead for retractable pencil length is 9/10 of core slot length; core slot length be frid A, frid B length 2/3, core groove near without lead for retractable pencil end be taper shape.The utility model beneficial effect: lead for retractable pencil is fixed; not easily slide and come off; decrease lead for retractable pencil waste, cover varnish protective layer, attractive in appearance and not easily wear surface pattern; frid adopts log plane system to form; solid not frangibility and unleaded core segment are convenient to next step processing process, and unleaded core segment is easy to degraded, environmental protection; core groove, near being conical without lead for retractable pencil end, makes lead for retractable pencil and core groove be affixed more firm.
Description
Technical field
The utility model relates to a kind of pencil, particularly relates to the pencil of the obstructed head of a kind of lead for retractable pencil.
Background technology
At present mostly pencil common is on the market that lead for retractable pencil and frid are isometric, and in use pencil shortens to such an extent as to inconvenience continues use gradually, and lead for retractable pencil is just dropped when not being fully used, and causes the waste of material.The obstructed head pencil of lead for retractable pencil of " the Easy Pencil " a by name of Japanese Design teacher design, core groove is isometric with frid, causes slicing remain the waste of core groove and be unfavorable for the post-production of residue centreless penholder.Number of patent application is 86204397.2 pencils disclosing the obstructed head of a kind of pencil-lead, is bonding one section of solid penholder of centreless in one end of pencil section, makes finished product in this way make inconvenience, bonds insecure, easily produce the shortcoming fractureed.
Utility model content
Technical problem to be solved in the utility model is: the pencil providing the obstructed head of a kind of lead for retractable pencil, solve pencil in use lead for retractable pencil slide, come off and problem that lead for retractable pencil can not use completely and waste.
The technical scheme that the problem that the utility model is the above-mentioned proposition of solution adopts is:
The pencil of the obstructed head of a kind of lead for retractable pencil, comprise frid A1, frid B2 and lead for retractable pencil 3, frid A1, frid B2 middle inside symmetry have core groove 4, lead for retractable pencil 3 arranges in core groove 4, frid A1 and frid B2 is glued together, and frid A1, frid B2 cross section are semicircle, and core groove 4 length is less than frid A1, frid B2.
Described frid A1, frid B2 outer side covers varnish protective layer, attractive in appearance and not easily wear surface pattern.
Described frid A1, frid B2 adopt log plane system to form, and solid not frangibility and unleaded core segment are convenient to next step processing process.
Described lead for retractable pencil 3 length is 9/10 of core groove 4 length, is conducive to saving lead for retractable pencil.
Described core groove 4 length be frid A1, frid B2 length 2/3, unleaded core segment be easy to degraded, environmental protection.
Described core groove 4, near being conical without lead for retractable pencil end, making lead for retractable pencil and core groove be affixed more firm, not easily slides.
Operation principle of the present utility model: to prune one end that lead for retractable pencil exposes with pencil sharpener during use, because lead for retractable pencil is not logical head, so there will not be lead for retractable pencil to slide the phenomenon come off in writing process, along with lead for retractable pencil constantly shortens, writer can continue to use by the hand-held other end without lead for retractable pencil, decrease the waste of lead for retractable pencil, and penholder adopts log plane system to form, the other end penholder without lead for retractable pencil also facilitates further processing and fabricating.
The beneficial effects of the utility model are: 1, lead for retractable pencil is fixed, not easily slide and come off, and decrease lead for retractable pencil waste, are conducive to economizing on resources.2, frid A, frid B outer side covers varnish protective layer, attractive in appearance and not easily wear surface pattern.3, frid A, frid B adopt log plane system to form, and solid not frangibility and unleaded core segment are convenient to next step processing process.4, lead for retractable pencil length is 9/10 of core slot length, is conducive to saving lead for retractable pencil.5, core slot length be frid A, frid B length 2/3, unleaded core segment be easy to degraded, environmental protection.6, core groove is near being conical without lead for retractable pencil end, lead for retractable pencil and core groove is affixed more firm, not easily slides.

Wherein, 1-frid A, 2-frid B, 3-lead for retractable pencil, 4-core groove.
Detailed description of the invention
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
With reference to Fig. 1-2, the pencil of the obstructed head of a kind of lead for retractable pencil described in this detailed description of the invention, comprise frid A1, frid B2 and lead for retractable pencil 3, frid A1, frid B2 middle inside symmetry have core groove 4, and lead for retractable pencil 3 arranges in core groove 4, and frid A1 and frid B2 is glued together, frid A1, frid B2 cross section are semicircle, and core groove 4 length is less than frid A1, frid B2.
Described frid A1, frid B2 outer side covers varnish protective layer, attractive in appearance and not easily wear surface pattern.
Described frid A1, frid B2 adopt log plane system to form, and solid not frangibility and unleaded core segment are convenient to next step processing process.
Described lead for retractable pencil 3 length is 9/10 of core groove 4 length, is conducive to saving lead for retractable pencil.
Described core groove 4 length be frid A1, frid B2 length 2/3, unleaded core segment be easy to degraded, environmental protection.
