There are four, be embedded in collet 9, head end connection pipe body 3 and intermediate connection tube 2 be fixedly connected can be as shown in the figure interference
Cooperation.
The embodiment of the present invention two does not have to the working method of timber to sharpen a pencil certainly, and the present invention does not have to the packet that sharpens a pencil certainly of timber
The intermediate connection tube 2 for including hand-held pipe 1 and being connected to hand-held pipe front end, 2 front end of intermediate connection tube are connected with head end company
Adapter tube 3, be successively arranged in the hand-held pipe 1, intermediate connection tube 2 and head end connection pipe body 3 inner tube 5 for accommodating pencil-lead 4,
Limit top cover 6, elastic collet 7 and the collet 9 with interior bite 8,5 periphery wall of said inner tube are equipped with close to the position of front end
Flange 10 of the overhead on hand-held pipe front end face is equipped with fluting seam 11 in the position of inner tube front end, and the limit top cover 6 is close
The inner hole 12 of 5 one end of inner tube is tapered, and the inner hole 12 of the taper and the periphery wall of inner tube front end cooperate in shrink or loosen
Pipe front end, the elastic collet 7 include periphery be fixed on intermediate connection tube central tube 13, be located at central tube rear end undergauge
Inner spring 14 on stepped part and it is set in inner spring periphery and the outer tube 16 with inward flange 15,15 end face of the inward flange top
It sets in one end of inner spring 14, the head end connecting tube 3 is fixed on intermediate connection tube 2, and 9 inner hole of collet is set in central tube 2
Periphery, collet periphery wall has protruding pin 24, and the internal perisporium of the intermediate connection tube is equipped with the spiral shell of sharp protruding pin helical rotation

Returning spring 27;When work, first by the pencil core insertion inner tube of not timber, user presses the tail end of inner tube, inner tube
Front end insertion limit top cover inner hole in, make inner tube and inner hole forms one and to clamp pencil-lead mobile toward head end, squeeze simultaneously
It is mobile toward head end to push away the second top pressure spring, the second top pressure spring pushes outer tube open, and the inner hole of central tube is made to loosen open-shaped, lead
Pen core is pushed into central tube, and when user unclamps the pressing to inner tube tail end, the flange of inner tube is by the first press
It is replied under the action of spring, the front end of inner tube is separated with limit top cover, and the front end of inner tube, which is in, is not clamped pencil-lead, and
Outer tube does not receive the second top pressure spring conduct yet, and outer tube is made to reply and clamp pencil-lead, several pressing repeatedly, unclamping inner tube tail end
Secondary, pencil-lead is pushed to front end, stretches out from the head end of head end connecting tube, while during pressing, the first top pressure spring
Collet 9 is acted on by near head end, moves the protruding pin 24 of collet 9 along 25 spiral of helicla flute, the interior bite 8 in collet 9 is
Pencil-lead is cut.
The main distinction of embodiment one and embodiment two be sharpening pencil core collet 9 and with head end connecting tube 3, intermediate
The difference of the connecting structure of connecting tube 2, embodiment one can be manually rotated cutting by user, and embodiment two is movement pressing
When cap 23, that is, automatic cutting, more automatically, convenient.
Pencil-lead after pencil-lead use is very short, when needing replacing, by pressing pressure cap 23 several times repeatedly, after the use
It can deviate from, or directly pull up pressure cap 23, new pencil-lead is packed into inner tube 5, cover pressure cap 23, press repeatedly several times
Pressure cap 23, the pencil-lead after the use can be deviate from;Or directly unscrew hand-held pipe 1, intermediate connection tube 2 and head end connecting tube 3
To take out pencil-lead.
In addition, the maximum feature of pencil is that expressive force is strong in hard-tipped pen calligraphical works writing process, even same branch pencil,
Firmly different, the line color depth degree write out is also different, and in other words, it becomes in addition to that can show the thickness of lines
Change, moreover it is possible to show the depth variation of color, therefore, the style of writing stereovision of pencil is stronger, and the skin texture that can be showed is more than other
Similar writing implement is abundant.
Traditional pencil is the important tool of child's study, and even more study hard-tipped pen calligraphical works is irreplaceable, and propelling pencil pen
Core, which easily snaps off, to be not easy to write, and the pencil-lead that the application uses only has lacked lumber layer, therefore as traditional pencil-lead
It can equally write out the text rich in stereovision.
After the present invention does not have to being sharpened a pencil certainly by the way that carbonaceous pencil-lead is put into inner tube of timber, pressing basic inner tube can will
Carbonaceous pencil-lead stretches out head end, by turn head end connecting tube, makes the collet being connected with head end connecting tube and interior cutting thereon
Knife cuts carbonaceous pencil-lead, and the pencil can be used directly i.e., has not only saved the use of timber, but also improves and make
Convenience.
Above-listed preferred embodiment, has been further described the object, technical solutions and advantages of the present invention, is answered
Understand, the foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
