Description

One kind, which is exempted to cut, to be exempted from by writing continuous pencil

Technical field

Exempt to cut the present invention relates to pencil technical field more particularly to one kind and exempt from by writing continuous pencil.

Background technique

Pencil be it is a kind of be used to write and dedicated class of drawing sketch, away from modern existing more than 400 years history.Wherein, The pencil of drawing sketch is divided into all polymorphic types.Pencil is a kind of hand-held pen, tool for writing, painting on paper, it is With graphite be pen core and rod is surrounding layer and is made, and the tail end of pencil can also have an erasing rubber, pencil and its His pen is the difference is that its person's handwriting is easy to be rubbed off.The pencil of black is " wood is black ", and crayon is " the wooden color ". Modern pencil is manufactured with " graphite " and clay, and graphite adds more, and pen core is softer, color is more black；And clay adds more More, pen core is then harder, and color is more shallow.Pencil is still called pencil now, is the pen because of earliest extremely shapeless or similar pencil For manufactured by " lead " metal, then then again because ancient times the Dark Ages is when chemical developer only just imparts rudimentary knowledge to beginners, people miss graphite It is thought as one kind of lead, therefore " pencil " word is handed down in all multilingual and east-asian language, is widely used and do not correct. Existing pencil just can be used after cutting system processing, and pencil-lead frangibility.

Summary of the invention

The purpose of the present invention is to solve disadvantage existing in the prior art, and the one kind proposed is exempted to cut and is exempted from by writing constantly Pencil.

To achieve the goals above, present invention employs following technical solutions:

One kind, which is exempted to cut, to be exempted from by writing continuous pencil, including handwriting, and the rear end of the handwriting is equipped with pen stand, symmetrical on the pen stand Equipped with block, symmetrically there are two briquettings for rotation connection on the pen stand, and briquetting engages with handwriting, between the block and briquetting Equipped with the first spring, the pen stand is equipped with support base, and support base is located at the inside of handwriting, and the support base is equipped with card slot, The bottom end of the card slot is equipped with second spring, is symmetrically arranged with two fixing seats, two fixing seats on the inner wall of the handwriting Opposite side is symmetrically arranged with four fixed blocks, limit sleeve is equipped between two fixed blocks, the inside of the handwriting is also Level is equipped with bearing, and the bearing inner sleeve is equipped with outer ring body, is rotatably connected to inner ring body in the outer ring body, the inner ring body Inner wall is equipped with circular orbit, is symmetrically arranged with four rotation fixed blocks in the circular orbit, and each rotation fixed block with Outer ring body connection, each rotation fixed block are equipped with link block, the two sides of the link block far from one end of circular orbit It is equipped with wedge-shaped catch, link block is equipped on two adjacent wedge-shaped catch, is led on two adjacent link blocks It crosses third spring and is connected with latch segment jointly, attachment base is equipped on each latch segment, is all provided on each attachment base There is arc groove, four L-type limited blocks is symmetrically arranged on the inner wall of the inner ring body, and L-type limited block is respectively positioned on corresponding arc In shape slot, it is symmetrically arranged with four lantern rings on the lateral wall of the outer ring body, is equipped with rope between each lantern ring and attachment base Rope is equipped with pen core in the card slot, limit sleeve and inner ring body jointly, is equipped with screw thread on the outer ring body and inner ring body, described It is also extended through in handwriting equipped with the first worm screw and the second worm screw, and the first worm screw engages with inner ring body, and the second worm screw and outer ring body Engagement.

Preferably, the pen core is made of natural graphite.

Preferably, equidistant on the inner wall of the card slot to be equipped with multiple semicircle rubber blocks.

Preferably, the handwriting is made of rigid plastics.

Preferably, the rear end of the handwriting is symmetrically arranged with two flutings, is arranged with two rotating blocks in each fluting, and two The 4th spring is equipped between a rotating block, and each rotating block is rotatablely connected with pen stand.

Preferably, the limit sleeve is between bearing and pen stand.

In the present invention, due to the elastic reaction of the first spring, two briquettings can push down handwriting, play the work of fixed pen stand With due to the elastic reaction of the 4th spring, two rotating blocks are separately fastened in fluting, also play fixed pen stand, by pen The end of core is placed in the semicircle rubber block in support base, and the middle part of pen core passes through two limit sleeves at this time, and the front end of pen core is worn It crosses outer ring body and extends from the front end of handwriting, pen core can be inserted into from pen tip, be placed in again after also can be placed in support base In handwriting, after pen core is placed, locked using outer ring body and inner ring body；When needing to lock pen core, outer ring body It remains stationary, i.e., the first worm screw remains stationary, and the second worm screw is rotated, so that inner ring body rotates, so that L-type limited block leaves connection Arc groove on seat, since the elastic reaction of third spring needs to take out pen so that pen core can be locked by four latch segments When core, inner ring body is remained stationary, i.e., the second worm screw is motionless, rotates the first worm screw, so that outer ring body rotates, utilizes rope on lantern ring Pulling force so that locking block reset, be stuck in L-type limited block in arc groove.Structure of the invention is stablized, easy to use, Pen core convenient disassembly, pen core, which exempts to cut, to be write constantly, and is not necessarily to adjustment length.
