Description
[technical field]
The present invention relates to and write or drawing appliance technical field, specifically a kind of rod or plastic bar or metallic rod full automatic pencil.
[background technology]
China is Wood-bar pencil big producing country, and the output of last year is up to 15,000,000,000, but real data this and more.In output sum, be wherein export to abroad mostly 80%.And for protecting forest resources; there is planning in external a lot of country to the use of forest; the output of restriction Wood-bar pencil; Chinese then consume the resource of descendants in a large number in order to foreign exchange; more than ten years are appealed by timber relevant department in short supply; but fail to cause everybody attention, Wood-bar pencil output is still in continuous rising.Thousands of people is also constantly sharpening a pencil, contaminated environment, destroys forest, and unconsciously thinks that with pencil sharper pencil be right and proper, also continually develop pencil sharpener.
Pencil has centuries history, has and easily writes and be easy to erasing out handwriting, is beneficial to student's exercise, use of working out a draft or draw, although promoted out erasable ball pen, gel ink pen afterwards, does not all replace pencil.Pencil develop into human culture development play great role, and pencil be also learn to write at the beginning of each child must use writing implement.But nib can be thicker in use for some time for pencil, at this moment just needs to sharpen a pencil, sometimes write tens words and just will repair and cut core, even and if also cannot ensure to write the consistent of handwriting thickness completely like this, use inconvenience.Also have a kind of thin propelling pencil in prior art, its relatively common Wood pencil compares environmental protection and carries out repairing cutting after writing a period of time.But propelling pencil also has its deficiency, as easily broken core, often will press adjustment dew core length, and have some limitations due to it, lower pupil can not use.
And full automatic pencil of the prior art is non-sharpenning, need not write by kinetic energy always.But current auto-compensation pencil can be divided into full-automatic propelling pencil and full automatic pencil.Wherein, full-automatic propelling pencil has the repertoire of the thin propelling pencil of pulsating, sandwich, Chu Xin, send core, press and once send one section of core, write line weight unanimously without the advantage of core finishing, it is the sandwich parts of auto-compensation and draw core components to introduce in propelling pencil, has the lead for retractable pencil that need not be worn by kinetic energy auto-compensation in writing, until a lead for retractable pencil is finished, can not writes and will press and affect thinking because exposing lead for retractable pencil.But the same propelling pencil of this kind of product appearance, very easily confuses general activity pencil.This product is applicable to adult and uses, and outward appearance can have various forms, is applicable to the selection of user.The upgrading products of propelling pencil.But the pen going out lead for retractable pencil by kinetic energy is not easily grasped, school specifies that lower pupil can not use; And another kind of full automatic pencil, its outward appearance resembles pencil, inside only has a lead for retractable pencil, can only write, and lead for retractable pencil can come out to a lead for retractable pencil always and be finished, and can not press, non-sharpenning, is applicable to primary grades pupil and uses.But inside only have a lead for retractable pencil, lead for retractable pencil is finished needs nib to extract, and manually a lead for retractable pencil is pushed into chuck.Change core more difficult, not as propelling pencil, to change core easy.
[summary of the invention]
Object of the present invention is exactly to solve deficiency of the prior art and defect, provides a kind of novel structure, easy to use and a kind of Full-automatic mechanical pencil with wood rod of environmental protection.
For achieving the above object, design a kind of Full-automatic mechanical pencil with wood rod, comprise and draw core components, sandwich parts, send core components and afterbody part, it is characterized in that being provided with thin-wall metal bushing in described sandwich parts, cavity is provided with in described thin-wall metal bushing, circular hole is provided with in the middle of bottom thin-wall metal bushing, thin-wall metal bushing bottom periphery is provided with push rod work limited block, described thin-wall metal bushing top is provided with and connects spiral shell parts, the described spiral shell parts endoporus that connects is provided with step, connect spiral shell component top and draw the point cover in core components to be connected, push rod one end in core components is sent to coordinate with the interference activity of sandwich parts liner hole, and by inner side limiting-position at the bottom of thin-wall metal bushing hole, spring and core storage tube is provided with outside push rod, spring one end withstands thin-wall metal bushing rear end face, the spring other end withstands core storage tube one end, wooden penholder is provided with outside core storage tube, connect with wooden penholder glue accessory outside thin-wall metal bushing.
Glued joint with rod bottom positioning pipe after described afterbody part comprises rear positioning pipe, tail cap, rubber seat and rubber, core storage tube afterbody is connected with rubber seat and rubber one end in the pore of rear location, and described rear positioning pipe, rubber seat and rubber are arranged in tail cap.
Reaming is carried out at described wooden penholder two, and thin-wall metal cover is arranged at the front hole of wooden penholder, and rear positioning pipe is arranged in wooden penholder metapore.
Be provided with intermediate plate and steel ball in described sandwich parts, form brake, lead for retractable pencil only export but no import with the clamp ring of the quoit conical surface, spring, liner, described sandwich parts coordinate at thin-wall metal bushing internal clearance.
Described point cover profile is step cone structure, and connects spiral shell parts and is connected, and the interior retaining core pipe of point cover is provided with damping, has spring and back-up ring outside retaining core pipe.
Described push rod and core storage tube close-fitting, spring is arranged between thin-wall metal bushing and core storage tube, and thin-wall metal bushing one and the interference activity of sandwich parts liner hole are connected.
The junction that described wooden penholder and tail overlap parts is that plane is connected or inclined-plane connects or cambered surface connects or is connected with a joggle.
Instant invention overcomes full automatic pencil machine core in prior art and can not load the defect in standard rod, compared with the existing technology, provide a kind of brand-new Full-automatic mechanical pencil with wood rod, solve and movement is loaded this key technology in rod, and emphasis core apparatus technique effect of the present invention is obviously outstanding.Outward appearance of the present invention is similar to pencil shape, can make and use the colony of pencil more acceptant, but its in use non-sharpenning, need not press, constantly can write, therefore have again the advantage of full automatic pencil concurrently.When lead for retractable pencil is finished, only need unplugs tail cap, can knockout be pressed, convenient as propelling pencil, change in core process hand of can not making dirty, and have the series of products of 0.7,0.5 millimeter of specification, meet the instructions for use of different personnel, particularly the use of student's pencil, applied widely and environmental protection practical.
