The pencil core feeding type pencil without sharpening is characterized in that a core fixing pressure-resistant ring which can lock the lead core tightly is arranged inside the pencil mouth sleeve. The core fixing pressure-resistant ring can efficiently prevent the lead core sliding, and the thickness of the used lead core can be changed freely according to the needs of users. The exposed length of the lead core can also be adjusted at any time. With advantages of novel design, simple structure, convenient operation, low cost, etc., the utility model is especially suitable for junior school students to use.
Description
The utility model relates to stationery, especially a kind of stepwise feed of writing-core pencil.
Traditional pencil is wooden stick's pencil, and it is formed through glue bond by two semi-cylindrical penholders and lead for retractable pencil.The Wood pencil price is low, is subjected to people's welcome, but Wood pencil in use needs with the cutter outer wooden stick of pen core of pruning, and can write after pen core is exposed.The exempt from customs examination user does not make troubles, especially to children just more not.In addition, Wood pencil is in use cut along with continuous cutter, and the length of Wood pencil is shorter and shorter, and is final, will influence the gripping of hand.And do not make as yet that the residual head of the Wood pencil of using up abandons can cause waste.And existing propelling pencil, complex structure, price height and pencil-lead size can not arbitrarily be changed, and pencil-lead is fixing not firm, problems such as frangibility.
The purpose of this utility model is the deficiency that exists at above-mentioned pencil, and a kind of stepwise feed of writing-core pencil is provided.
Stepwise feed of writing-core pencil of the present utility model comprises: penholder, the cap for brush, pen are chewed cover and lead for retractable pencil, it is characterized in that: and penholder and pen are chewed the pen of external threading link and are chewed and be provided with one in the cover and can screw in the solid withstand voltage circle of core of gentle matter that pen be chewed the degree of depth crimp of cover along with penholder, Gu the withstand voltage circle of core is an important actor shape, the center has the through hole of tandem arrangement lead for retractable pencil, and the lead for retractable pencil of tandem arrangement in the solid withstand voltage ring through hole of core chewed with pen at penholder and be locked being connected in the process of screwing of cover.
Stepwise feed of writing-core pencil of the present utility model, adopt the solid core lock sleeve of the solid withstand voltage circle of core of gentle matter as lead for retractable pencil, can prevent the slip of lead for retractable pencil effectively, because withstand voltage circle is gentle material, so in its central through hole the lead for retractable pencil of tandem arrangement slightly, carefully can arbitrarily change according to user's needs, the exposed length of lead for retractable pencil also can be adjusted at any time.Advantages such as stepwise feed of writing-core pencil of the present utility model has modern design, and is simple in structure, easy to use, and price is low.It has overcome the conventional wooden pencil need cut system, wastes big defective, has also solved existing propelling pencil lead for retractable pencil size and can not change problems such as cost height.Be that a kind of students of the junior years of being particularly suitable for use pencil.
Concrete structure of the present utility model is provided in detail by the following drawings and embodiment.
Fig. 1 is the structural representation of stepwise feed of writing-core pencil
Embodiment: can be clear that from Fig. 1: the stepwise feed of writing-core pencil is chewed the penholder that cover 2, last penholder 4 and following penholder 3 constitute by lead for retractable pencil 1, pen, and the cap for brush 5 is formed, be connected by screw thread 8 between the cap for brush 5 and the last penholder 4, be connected by screw thread 7 between last penholder 4 and the following penholder 3, following penholder 3 is chewed between the cover 2 with pen and is connected by screw thread 6, pen is chewed and is provided with the solid withstand voltage circle 9 of core of an important actor shape in the cover 2, Gu but the center of the withstand voltage circle 9 of core has the through hole of tandem arrangement lead for retractable pencil 1, Gu the core circle of anti-core the 9 is made for rubber-plastics material.Following penholder 3 is chewed cover 2 in being connected the process of screwing with pen, and the end face of following penholder 3 contacts and pushes with the solid withstand voltage circle 9 of core, and makes the lead for retractable pencil of the withstand voltage circle 9 distortion locking tandem arrangements of solid core in solid withstand voltage circle 9 central through holes of core, makes it fixing.For storage core chamber 10, can stock lead for retractable pencil in the chamber in the last penholder 4.If tandem arrangement ballpoint pen core in solid withstand voltage circle 9 central through holes of core has then become a ballpoint pen.Between the cap for brush 5 and the penholder pen hanging can be set, pen is chewed on the cover 2 can be equipped with the pen cap.
