Description

Automatic ever sharp pencil

Technical field

The utility model relates to a kind of propelling pencil, relates in particular to a kind of pencil by the method feeding pen core that slides in the shell of vertical fluting.

Background technology

Pencil has other incomparable correction advantage easily, is also used drawing tools such as particularly indispensable writing implement in pupil's study, and drawing, drawing up to now widely.Pencil is the most common, the most popular a kind of stationery.

Existing pencil kind is a lot, generally is divided into the Wood pencil and the slide core pencil of fixed core.The Wood pencil of fixed core has simple in structure, easily manufactured advantage, uses inconvenient defective but it has, and the pen core of pencil is being coated by wooden, needs cutting in the time of use, and is pretty troublesome.And the manufacturing of Wood pencil expended a large amount of timber resources, is unfavorable for the protection of environment.The chip that chips away in addition also severe contamination around environment.The slide core pencil has advantage easy to use, and general its structure of existing slide core pencil is made up of the shaft of a writing brush, nib, spring, collet, the cap for brush etc., and pen core is fixed by collet, by pressing the cap for brush pen core is stretched out in collet.After long-time use of this pencil process, collet will become flexible, the tight pencil-lead of folder, and the pen core of exerting oneself a little when causing writing can't be write with regard to sliding backward retraction.This propelling pencil has obvious defects: often change lead for retractable pencil, the lead for retractable pencil consumption is big, and pen is easy to damage.

The utility model content

Technique effect of the present utility model can overcome above-mentioned defective, and a kind of automatic ever sharp pencil is provided, and it is simple in structure, and cost is low.

For achieving the above object, the utility model adopts following technical scheme: it comprises the cap for brush, penholder, and the penholder inner hollow forms inner chamber, and the penholder inner chamber is provided with lead for retractable pencil, and at least one side of penholder longitudinally is provided with open slot, and open slot is communicated with inner chamber; Be with the card that slides on the penholder, the card inboard of sliding is provided with boss, and the boss of the card that slides moves along open slot.

The penholder inner chamber is provided with sleeve pipe, and sleeve pipe is provided with the bar-shaped trough corresponding with the penholder open slot, and lead for retractable pencil places in the sleeve pipe, can more effectively locate lead for retractable pencil like this, can also prevent that lead for retractable pencil from breaking.The sidewall of inner chamber or the lateral wall of sleeve pipe are provided with fin, are provided with standby lead for retractable pencil between the fin, can change at any time after lead for retractable pencil uses up.The pen tip position of penholder is provided with the binding groove of opening, and nib outside socket fastening cap, nib and fastening cap be by being threaded, and can realize the effect of fastening lead for retractable pencil by the rotation fastening cap, and lead for retractable pencil is mobile when preventing to write.

Erasing rubber is equipped with in the cap for brush outside, and cap for brush inboard is provided with the sand paper layer or adopts tiny metal file, does not need to carry other cutter, rubber like this, can realize lead bullion is cut purpose thin or that wipe.According to different use occasions, penholder can adopt plastics or metal material to make, and with respect to existing wooden or propelling pencil, cost reduces greatly.

The utility model is simple in structure, and is easy to use, and pen core not frangibility and synthlipsis goes back, and can substitute wooden lead bullion pencil and propelling pencil fully, makes full use of lead for retractable pencil, save timber resources, and cost is low.

The specific embodiment

Embodiment 1

This device comprises the cap for brush 1, penholder 2, and penholder 2 inner hollow form inner chamber 12, and penholder inner chamber 12 is provided with lead for retractable pencil 7, and a side of penholder 2 longitudinally is provided with open slot 4, and open slot 4 is communicated with inner chamber 12; Be with the card 3 that slides on the penholder 2, card 3 inboards of sliding are provided with boss 8, and the boss 8 of the card 3 that slides moves along open slot 4.

Boss 8 is stuck in the top of lead for retractable pencil 7, and the card 3 that slides slides and drives moving of boss 8, lead for retractable pencil 7 can be ejected the nib of penholder 2 by boss 8.Can adjust the outstanding length of lead for retractable pencil 7 during use arbitrarily; Directly lead for retractable pencil 7 is got final product by arriving in the penholder 2 when not in use.

Embodiment 2

Penholder inner chamber 12 is provided with sleeve pipe 10, and sleeve pipe 10 is provided with the bar-shaped trough corresponding with penholder open slot 4, and lead for retractable pencil 7 places in the sleeve pipe 10, can effectively locate lead for retractable pencil 7 like this, prevents to rock.The sidewall of inner chamber is provided with fin 9, is provided with standby lead for retractable pencil 7 between the fin 9.Other is with embodiment 1.

Embodiment 3

The pen tip position of penholder 2 is provided with the binding groove 5 of opening, nib outside socket fastening cap 6.Nib and fastening cap 6 be by being threaded, the excessive defective that causes lead for retractable pencil 7 to return of exerting oneself in the time of can avoiding writing better like this.When having between the nib of sensation lead for retractable pencil 7 and penholder 2 when loosening, will screw between fastening cap 6 and the nib, because the binding groove 5 of nib is a hatch frame, like this can be with the further past internal contraction of nib, fastening between realization lead for retractable pencil 7 and the nib.Erasing rubber 11 is equipped with in the cap for brush 1 outside, and the cap for brush 1 inboard is provided with the sand paper layer.Other is with embodiment 1

Embodiment 4

The lateral wall of sleeve pipe 10 is provided with fin 9, is provided with standby lead for retractable pencil between the fin 9.Other is with embodiment 2.

Embodiment 5

The both sides of penholder 2 longitudinally are provided with open slot 4, and open slot 4 is communicated with inner chamber 12; The card 3 inboard correspondences of sliding are provided with two boss 8.Other is with embodiment 2.

Embodiment 6

The sidewall of inner chamber is provided with fin 9, card 3 is pushed down standby lead for retractable pencil 7 when the lower slider in order to avoid sliding, the left and right sides at the sidewall upper shed groove 4 of inner chamber additionally is provided with two fins 9, standby lead for retractable pencil can be housed between boss 8 and the adjacent fin 9 like this, avoid owing to misoperation, standby lead for retractable pencil stops the slip of the card 3 that slides.Other is with embodiment 2.

Embodiment 7

The sidewall of inner chamber is provided with fin 9, is provided with standby lead for retractable pencil 7 between the fin 9.Because the length of fin 9 self is longer, all fins 9 can surround a cylindrical structure, and lead for retractable pencil can not spill from the interval between the adjacent fin 9.So both can reach fixing lead for retractable pencil, lead for retractable pencil rocks when preventing to write effect, needn't additionally increase sleeve pipe again, greatly reduce cost.Other is with embodiment 1.
