Description
Technical field
The utility model relates to a kind of pencil, a kind of specifically propelling pencil.
Background technology
In the middle of study and work, be unable to do without pencil, especially drawing or during drawing, especially essential tool.And wooden pencil in use, often needs volume to cut, and when volume was cut, the pencil-lead that can fracture had unavoidably brought inconvenience in use.At present, a lot of propelling pencils is arranged on the market, most of propelling pencils mainly are made up of penholder, the clamping element that is arranged on lead for retractable pencil pipe, pencil-lead and lead gripper pen core in the penholder.
The automatic pencil structure that has is very complicated, makes manufacturing cost high.
The utility model content
The utility model technical issues that need to address provide a kind of propelling pencil simple in structure.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of propelling pencil comprises top cover, pen container, pen core and the nib that flexibly connects with pen container, and lower end, said top cover side is provided with convexity, is provided with push rod below the top cover; Said pen container is made up of chute that holds top cover and the cavity that holds push rod and pen core, the equal in length of chute, cavity and push rod, and the chute inwall is provided with the some and protruding groove that cooperates; Cavity lower port inwall is provided with the holder of clamping pen core; Said nib is an infundibulate, is provided with the outlet of pen core.
This practical improvement is: flange is set below the said push rod, and flange matches with the cavity internal diameter; Said holder is an elastic ring.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
Pen container is provided with chute and cavity; And chute and cavity length equate; The chute inwall is provided with groove, and top cover is provided with the convexity with groove fit, is provided with push rod below the top cover; And the length of push rod equals the length of chute and cavity, and it is descending that such structural design can be controlled pen core easily; Be set to the flange that cooperates with the cavity internal diameter below the push rod, be convenient to push rod and promote pen core downwards; Pen container and nib are to flexibly connect, and can dismantle nib easily, and pen container cavity lower port inwall is provided with the holder of clamping pen core, fixedly pen core.

The specific embodiment
Below in conjunction with description of drawings the utility model is explained further details:
As shown in Figure 1, propelling pencil comprises top cover 1, pen core 8, pen container 5 and nib 10.Be provided with convexity 2 in the lower end of top cover 1 side, below top cover 1, be provided with push rod 11, push rod 11 is cylindrical, and below push rod 11, is provided with flange 6; Pen container 5 is made up of chute 4 and cavity 7 two parts, chute 4 be positioned at cavity 7 above, and chute 4, cavity 7 and push rod 11 these equal in length of three, chute 4 can hold top cover 1, is provided with some grooves 3 that cooperate with convexity 2 at chute 4 inwalls; Cavity 7 internal diameters match with flange 6, are provided with the holder 9 of clamping pen core 8 at cavity 7 lower port inwalls, and holder 9 is an elastic ring, can clamping pen core 8; Said written 10 is infundibulate, is provided with the outlet of pen core 8.
During use, the nib 10 of outwarding winding, rotating cap 1; Be placed on the uppermost position of chute 4 to top cover 1, make protruding 2 be positioned at the chute 4 of first groove 3 positions slideway, pen core 8 through nib 10, pass holder 9 and put in the cavity 7; At this moment, holder 9 is clamped pen core 8; Then, rotating cap 1 makes protruding 2 to enter in first groove 3; The part that this time, pen core 8 exposed nib 10 is used, and when the pen core 8 that exposes nib 10 uses up, rotates and presses top cover 1; Protruding 2 enter in the next groove 3, the pen core 8 that push rod 11 promotion downwards is positioned at, and pen core 8 lower ends are ejected; After this pen core 8 uses up, be withdrawn into initial conditions to top cover 1, repeat said process and get final product.
