Abstract
A lead outlet device of an extensible bullet movable pencil comprises a movable hollow machine core arranged in a shell. The hollow machine core is sleeved with a reset spring, all sections of leads are sequentially arrayed and placed in the hollow machine core, the front portion of the hollow machine core is elastically split, and the diameter of the inner wall of the corresponding part of the shell is transitionally decreased, and the inner wall of the corresponding part of the shell is matched with the elastic splitting portion of the hollow machine core to form a pressing and binding structure. A chuck seat is further connected at the front end of the shell, an elastic clamping jaw is arranged at the front end of the chuck seat and is used for clamping the leads, and the movable stroke of the hollow machine core in the shell is the same as the length of one section of leads. The lead outlet device of the extensible bullet movably pencil is reasonable in structural design, less in part, convenient to produce and assemble and simple in operation. In the using process, the hollow machine core only needs to be pressed manually, the bullet leads can be discharged out section by section, using is easy, and the reliability is high. In the action process, internal mechanisms such as the hollow machine core can completely not be exposed out of the shell, and the appearance of the movable pencil is attractive, and damage is not easy.
Description
Technical field: the utility model relates to the core apparatus that of a kind of core apparatus that goes out of propelling pencil, particularly sub warhead propelling pencil.
Background technology: common propelling pencil is all to use elongated pencil-lead, can be used the long period continuously, but cannot reach thickness and the soft durometer effect of Wood-bar pencil.Now also had and used the propelling pencil of exempting to cut bullet pencil, every section of pencil-lead is shorter, approach the result of use of Wood-bar pencil, it is reasonable not that but existing sub warhead propelling pencil goes out the structure of core apparatus, be generally cuff tongue spring outside hollow movement, utilize pencil-lead deadweight and spring-latch to stir knockout.In use, spring-latch may destroy movement wall, the spring not knockout of also easily dislocating.And, there is the front portion mechanism of movement of suitable a section can expose housing front end, very not attractive in appearance, also easily damage.
Summary of the invention: for the deficiencies in the prior art, it is a kind of reasonable in design that the utility model provides, and the core apparatus that of sub warhead propelling pencil is cut in easy to operate exempting from.
The utility model comprises and is placed in movably hollow movement of housing, on hollow movement, cover has back-moving spring, each section of pencil-lead is sequentially placed in hollow movement, the anterior elasticity jag of this hollow movement, the inner diameter transition of housing appropriate section is dwindled and is coordinated formation compressing restraining structure with the elasticity jag place of hollow movement; The front end place of housing is also connected with base of the carrier head, and the front end of this base of the carrier head is provided with elastic card claw for lead gripper pen core, and the removable stroke of hollow movement in housing is identical with the length of one section of pencil-lead.
Reasonable in design of the present utility model, parts are few, produce easy to assemblyly, operate also very simply, only need manually press hollow movement in use, can send piecemeal bullet pencil, are easy to use, and reliability is high.And in course of action, the internal mechanisms such as hollow movement can not expose outside housing completely, make the handsome in appearance of propelling pencil, not fragile.
Below in conjunction with drawings and Examples, further illustrate the utility model.
Accompanying drawing explanation: Fig. 1 is the main structure schematic diagram of embodiment 1.
Fig. 2 be Fig. 1 press knockout view.
Fig. 3 is the hollow movement schematic perspective view in embodiment 1.
Fig. 4 is the base of the carrier head schematic perspective view in embodiment 1.
Fig. 5 is the main structure schematic diagram of embodiment 2.
Fig. 6 be Fig. 5 press for the first time knockout view.
Fig. 7 be Fig. 5 press for the second time knockout view.
Embodiment 1: as shown in Figures 1 to 4, movably hollow movement 2 is placed in housing 1, on hollow movement 2, cover has back-moving spring 3, each section of pencil-lead 4 orders are placed in hollow movement 2, the anterior elasticity jag of this hollow movement 2, the inner diameter transition of housing 1 appropriate section is dwindled and is coordinated formation compressing restraining structure with the elasticity jag place of hollow movement 2.The front end place of housing 1 is also connected with base of the carrier head 5, and the front end of this base of the carrier head 5 is provided with elastic card claw 6 for lead gripper pen core 4, and the removable stroke of hollow movement 2 in housing 1 is identical with the length of one section of pencil-lead 4.
The lateral wall of the present embodiment at the elasticity jag place of hollow movement 2 is provided with oblique branch 7 and contacts cooperation with the inwall of housing 1 appropriate section, and fiting effect is better like this.In the outside of base of the carrier head 5, housing 1 locate foremost be also connected with nib 8, form a full screen type shell, a whole like this shell is the same with conventional pen shell does not have exposed component, more attractive in appearance.
While needing knockout, press the end of hollow movement 2, make it a mobile stroke, the elasticity jag place of hollow movement 2 is subject to the inwall constraint of housing 1 appropriate section, mobile gathering simultaneously, withstands the rear end face of one section of pencil-lead 4 above, and this pencil-lead 4 is promoted to a stroke distances, also be the length of one section of pencil-lead 4, as shown in Figure 2, at this moment nib 8 is exposed at the tip of this pencil-lead 4, and rear portion is clamped by the elastic card claw 6 of base of the carrier head 5, can not retreat, can write use.Then back-moving spring 3 is replied hollow movement 2, only need repeat to press hollow movement 2, can send piecemeal each pencil-lead 4, very convenient.
Embodiment 2: as shown in Figure 5, the basic structure of the present embodiment and embodiment 1 are identical, but the anterior elasticity jag place of hollow movement 2 is that one is long and the other is short, and length spacing is one section of pencil-lead 4 length half, the removable stroke of hollow movement 2 in housing 1 is also half of one section of pencil-lead 4 length.
While needing knockout, first press once the end of hollow movement 2, make it a mobile stroke, the elasticity jag place of hollow movement 2 is subject to the inwall constraint of housing 1 appropriate section, mobile gathering simultaneously, the long end at elasticity jag place is withstood the rear end face of one section of pencil-lead 4 above, this pencil-lead 4 is promoted to a stroke distances, also i.e. half of one section of pencil-lead 4 length, as shown in Figure 6, at this moment nib 8 is not just exposed at the tip of this pencil-lead 4, and rear portion is clamped by the elastic card claw 6 of base of the carrier head 5, can not retreat.Then be reset spring 3 of hollow movement 2 is replied, press for the second time again the end of hollow movement 2, make it a mobile stroke, at this moment the short end at the elasticity jag place of hollow movement 2 can be withstood the rear end face of second from the bottom section of pencil-lead 4, make it a mobile stroke distances, just now top pencil-lead 4 also can be pushed to a stroke like this, i.e. half of one section of pencil-lead 4 length, as shown in Figure 7, at this moment half of top pencil-lead 4 exposed nib 8, and rear portion is clamped and can write use by the elastic card claw 6 of base of the carrier head 5.
The present embodiment is often pressed secondary and is sent one section of pencil-lead 4, the embodiment 1 that compares like this, and the stroke of hollow movement 2 reduces half, presses operation more comfortable, and structure can be compacter, makes whole shell more attractive in appearance.
