Abstract

The utility model relates to a propelling pencil capable of continuously propelling pencil lead, which solves the problem that the propelling pencil needs loading pencil leads from time to time and pencil leads is easy to be broken because of core shift of the lead clip piece. The improvement is that a pencil lead catheter is correspondingly disposed on the rear portion of the pencil lead mechanism, a tiny clip block is disposed on the rear portion therein, a pencil lead pore is disposed along the radial direction of the tiny clip block. The clip head behind the pencil lead catheter is two semi-spherical cylindrical pipes correspondingly matched, the diameter of the catheter composed of the two semi-spherical cylindrical pipes is matched with the pencil lead, a spring is disposed on the front sleeve of the clip head, the clip head is disposed in a guidance pipe, and rear portion of the guidance pipe is connected to the catheter. Applying the utility model, a plurality of pencil leads can be put in at one time, if one lead is used, the clip head will clip another pencil lead and delivers the same to the head of the pencil just by several pressing on the top. Therefore, frequent manual loading of pencil lead is not needed, no break of pencil lead occurs, and the pencil is convenient for use.

Description

Can go out the propelling pencil of pencil-lead continuously

Technical field

The utility model relates to a kind of propelling pencil.

Background technology

General on the top by several pen cores that allow down to the continuous propelling pencil of writing of nib, write a pen core after, the lid that need open the penholder rear end inserts a pen core again.Need the often operation pen core of packing into like this, use inconvenient, on the other hand, pupil's pen core that fractures easily that operates.The general sandwich spare of writing continuous propelling pencil is all formed by two, and pencil-lead fractures because of two sandwich spare core shifts easily during use.

Summary of the invention

Need often to adorn pen core and the sandwich spare problem because of core shift frangibility pencil-lead in order to solve existing propelling pencil, the utility model provides a kind of many pen cores of can once packing into, can go out the propelling pencil of pencil-lead during use continuously.

Concrete Technological improvement plan is as follows:

The propelling pencil that can go out pencil-lead continuously comprises hollow penholder, is provided with written mechanism in the hollow penholder successively, goes out pencil-lead mechanism and sleeve pipe; Nib mechanism comprises nib pipe and guide block, and the front end of written pipe extends outside the hollow penholder, and its middle part is provided with boss, and the rear sleeve of boss is provided with written spring; Go out pencil-lead mechanism and comprise sandwich spare, sandwich spare is positioned at band tapering sleeve pipe, and is arranged with the sandwich spring on the sandwich spare; The front end of sleeve pipe is with to go out pencil-lead mechanism corresponding, and its rear end is for putting the pen core mouth;

Also comprise the pencil-lead conduit, it is anterior, and rear portion is the little stepped hole of outer imperial palace in it, cooperates in the stepped hole to be provided with little fixture block with to go out pencil-lead mechanism corresponding, and the axial of little fixture block is the pencil-lead hole; The coaxial chuck that is provided with of pencil-lead rear end of conduit, chuck is the semicircle column jecket of two corresponding matching, the caliber of two semicircle column jecket compositions cooperates with pencil-lead, the same external diameter at two semicircle column jecket middle parts is provided with positioning boss, collet front is arranged with spring, chuck is positioned at guide pipe, and the rear end of guide pipe is connecting sleeve pipe.

Described sandwich spare is a tubulose, and the front portion is the pencil-lead pipe, and the rear portion is three intermediate plate shapes, and the rear portion radial cross-section is three lobes.

Useful technique effect of the present utility model is, once can put into several pen cores, write after one, by under several, chuck will clip another root pen core and send into conduit to nib on the top, does not so just need the manual pen core of often packing into, cause pen core to fracture, and the waste pen core.

The utility model has designed chuck and fixture block in the middle part of pen, and when pushing the top of pen, chuck will clip pencil-lead through fixture block, is easy to just pencil-lead be shifted onto nib.

Sandwich spare of the present utility model front portion is a tubulose, and the rear portion is three intermediate plate shapes, just can not fracture because of core shift when pencil-lead is entered process.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

Referring to Fig. 1, the propelling pencil that can go out pencil-lead continuously comprises hollow penholder, is provided with written mechanism in the hollow penholder successively, goes out pencil-lead mechanism and sleeve pipe 11; Nib mechanism comprises nib pipe 1 and guide block 3, and the front end of nib pipe 1 extends outside the hollow penholder, and its middle part is provided with boss, and the rear sleeve of boss is provided with written spring 2; Go out pencil-lead mechanism and comprise sandwich spare 6, sandwich spare 6 is positioned at band tapering sleeve pipe 4, and is arranged with sandwich spring 5 on the sandwich spare 6, and sandwich spare 6 is a tubulose, and the front portion is the pencil-lead pipe, and the rear portion is three intermediate plates, and the rear portion radial cross-section is three lobes, sees Fig. 2 and Fig. 3; Also comprise pencil-lead conduit 7, pencil-lead conduit 7 is anterior, and rear portion is the little stepped hole of outer imperial palace in it, cooperates in the stepped hole clip piece 8 is housed with to go out pencil-lead mechanism corresponding, and the axial of clip piece 8 is the pencil-lead hole; The coaxial chuck 9 that is provided with in pencil-lead conduit 7 rear ends, chuck 9 is the semicircle column jecket of two corresponding matching, the caliber of two semicircle column jecket compositions cooperates with pencil-lead, the same external diameter at two semicircle column jecket middle parts is provided with positioning boss, chuck 9 front portions are set with spring 10, chuck 9 is positioned at guide pipe, and the rear end of guide pipe is connecting sleeve pipe 11; The rear end of sleeve pipe 11 is for putting pen core mouth 12.

During use, put into many pencil-leads by putting pen core mouth 12, press the top of pen again, pencil-lead will enter chuck 9 along sleeve pipe 11, chuck 9 clips pencil-lead and inserts clip piece 8, enter sandwich spare 6 along pencil-lead conduit 7 then, through guide block 3 pencil-lead is delivered to nib pipe 1 again, so just can begin to have write.When writing, utilize the action of writing to defeat nib pipe 1, the written spring 2 of the inside will work, and pen core is constantly stretched out, and goes out pencil-lead when writing automatically and is difficult for writing disconnected effect thereby reached.
