Description

Propelling pencil

Technical field

The utility model relates to a kind of cultural tools, is a kind of propelling pencil specifically.

Background technology

At present, pencil is the most general, the most popular a kind of stationery, owing to have and alter advantage easily, so also be extensive use of up to now, particularly indispensablely in pupil's study writes, draw tool.At present, pencil generally is divided into two kinds of the Wood pencil of fixed core and slide core propelling pencils, and the wooden pencil of fixed core is simple in structure, easily manufactured, but because pencil-lead has timber to coat, and need peel during use to bother and expended a large amount of timber resources.The general structure of slide core propelling pencil is made up of the shaft of a writing brush, nib, spring, collet, the cap for brush etc., and structure is single, and the pencil-lead carefully lead that adopt are not the Wood pencil lead for retractable pencil specifications of standard more, and influence is used to a certain extent.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of propelling pencil simple in structure, reasonable in design, practical is provided.

In order to achieve the above object, the technical solution adopted in the utility model is: described nib is with a little opening outside, and be provided with chute, slip lid is installed in the chute, the lead for retractable pencil lock is installed in the inside of nib, the lead for retractable pencil lock divides lead for retractable pencil upper cover of lock and lead for retractable pencil lock lower cover two parts, one protruding place is arranged at lead for retractable pencil upper cover of lock top, lead for retractable pencil lock cap header down has a steady pin, and lead for retractable pencil upper cover of lock and lead for retractable pencil lock lower cover respectively have a groove at mating surface left and right sides opposite position, are placed with the arc spring steel plate in the groove, described pen container connects by head threads and links to each other with nib, the reducing bar is installed in the pen container, and the reducing club head has boss, and the end of pen container is a sleeve pipe, sleeve pipe not exclusively is closed with an opening on circumference, be provided with baffle plate at opening part, lead adopts to peg graft and links to each other with pen container, is provided with push pedal in the lead, end is equipped with cover, be provided with blade I in the described cap for brush head, afterbody is jagged, is provided with blade II in breach.

The utility model has the advantages that:

1, novel structure, uniqueness and reasonable in design;

2. adopt Wood pencil standard specification lead for retractable pencil, can deposit many lead for retractable pencils simultaneously, and have the lead for retractable pencil function of fining away, easy to use, save timber.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 4 as can be known, described in the utility model written 1 is with a little opening outside, and be provided with chute, slip lid 5 is installed in the chute, the lead for retractable pencil lock is installed in the inside of nib 1, the lead for retractable pencil lock divides lead for retractable pencil upper cover of lock 9 and lead for retractable pencil lock lower cover 2 two parts, one protruding place is arranged at lead for retractable pencil upper cover of lock 9 tops, lead for retractable pencil lock lower cover 2 heads have a steady pin, and lead for retractable pencil upper cover of lock 9 and lead for retractable pencil lock lower cover 2 respectively have a groove at mating surface left and right sides opposite position, are placed with the arc spring steel plate in the groove, described pen container 4 connects with nib 1 by head threads and links to each other, reducing bar 3 is installed in the pen container 4, and reducing bar 3 heads have boss, and the end of pen container 4 is a sleeve pipe 8, sleeve pipe 8 not exclusively is closed with an opening on circumference, be provided with baffle plate 11 at opening part, lead 6 adopts to peg graft and links to each other with pen container 4, is provided with push pedal 10 in the lead 6, end is equipped with cover 7, be provided with blade I13 in the described cap for brush 12 heads, afterbody is jagged, is provided with blade II14 in breach.

The utility model with after pen container 4 docks, constitutes an interlayer at lead 6 between lead 6 inwalls and sleeve pipe 8 outer walls, lead for retractable pencil leaves in this interlayer, can deposit many lead for retractable pencils simultaneously, seals up cover 7 then.When clockwise rotating lead 6, be in the lead for retractable pencil between lead 6 and the sleeve pipe 8, will under the promotion of push pedal 10, move ahead, when first lead for retractable pencil arrives sleeve pipe 8 opening parts, be subjected to the effect of baffle plate 11, enter in the sleeve pipe 8 by the opening of sleeve pipe 8.Pen container 4 just in time makes reducer pipe 3 inlet relative with sleeve pipe 8 outlets with after nib 1 is threaded, and the outlet of reducer pipe 3 is relative with the inlet that lead for retractable pencil is locked, and reducer pipe 3 head boss withstand on written 1 bottom of thread raised face, prevents to move after lead for retractable pencil from locking.The lead for retractable pencil that flow into sleeve pipe 8 thus can stretch out from nib 1 through reducer pipe 3, lead for retractable pencil lock successively.The arc spring steel plate of placing in lead for retractable pencil upper cover of lock 9 and the lead for retractable pencil lock lower cover 2 end face grooves has the certain deformation amount, when stressing, lead for retractable pencil upper cover of lock 9 jack-up are not separated with lead for retractable pencil lock lower cover 2, this moment, exposed from written 1 peripheral openings at protruding place, lead for retractable pencil upper cover of lock 9 tops, and lead for retractable pencil can move freely in the lead for retractable pencil lock.Promote slip lid 5, depress lead for retractable pencil upper cover of lock 9 lead for retractable pencil upper cover of lock 9 and lead for retractable pencil lock lower cover 2 are closely contacted, just fixing lead for retractable pencil.The cap for brush 12 heads are provided with blade I13, and the pen with rotary body just can be realized the lead for retractable pencil sharpening; More in short-term, be provided with blade II14 in the available cap for brush 12 afterbody breach lead for retractable pencil is scraped point at lead for retractable pencil, play the lead for retractable pencil effect of saving to a certain extent.
