Abstract
The utility model belongs to the writing appliance technical field, is a combination plastic tube propelling pencil applicable to the thick lead cord. The utility model comprises a penholder and a lead cord, which is mainly characterized in that the penholder consists of three parts, the upper part is coating bar, the bottom is a lead cord holding righting bar, the righting bar is covered inside the coating bar, a lead cord holding propeller post is arranged in the midheaven part between the two bars, the holding apertures of the holding part are respectively Phi 1.6 mm, the lead cord holding propeller post adopts the screw thread propeller post or the pushing propeller post. Compared with the prior art, the propelling pencil can hold a plurality of colors thick lead cord, has the advantages of convenient to be held, high utilization rate of the lead cord, and strong practicability.
Description
Technical field:
The utility model belongs to the writing appliance technical field, is a kind of multifunctional plastic pipe propelling pencil that is applicable to the lead bullion core.
Background technology:
In technique known, mostly disclosed plastic tube propelling pencil on the market is to adopt, as:
0.5mm,
0.7mm,
0.9mm lead for retractable pencil, its color is single, the plastic tube propelling pencil of thin lead for retractable pencil is inapplicable for the softer and easily broken color pencil lead of lead for retractable pencil.At present, consumption maximum and maximum lead for retractable pencils are
1.6mm but still adopt the pencil of wooden bar, the pencil of this wooden bar, the problem that exists in the use is: in cutting a process, the conference of exerting oneself is sometimes cut lead for retractable pencil disconnected, cause damage and waste, and what cut is wood chip fullly, influences health.In addition, wooden pencil uses when only being left 50～60mm at last, and usefulness is again held in inconvenience, just loses while you're at it, and therefore the utilization rate of wooden pencil lead core has only 60～70%, and not only wood consumption is big, complex manufacturing technology, and also the utilization rate of lead for retractable pencil is low.
Summary of the invention:
The purpose of this utility model provides and a kind ofly saves timber, and can be applicable to the multifunctional plastic pipe propelling pencil of the lead bullion core of various colors.
Realize that the technical scheme that the purpose of this utility model adopted is: this pen has penholder, lead for retractable pencil, principal character is: penholder is to be made of three parts, top is outer loop bar, the bottom is a lead for retractable pencil clamping righting rod, righting rod is sleeved in the outer loop bar, hollow part between two bars is provided with lead for retractable pencil clamping pushing ram, and the clamping aperture of its retained part is respectively
1.6mm being connected to each other of three bars constitutes multifunctional plastic pipe lead bullion propelling pencil of the present utility model.
The multifunctional plastic pipe lead bullion propelling pencil of making according to such scheme.Save the time that sharpens a pencil, can select different color and diameter to exist as required simultaneously
1.6mm the lead bullion core use, especially when drawing accompanying drawing, can change the good veriform lead for retractable pencil of grinding at any time, as the lead for retractable pencil that charts such as homalocephalus type, tip type, brachycephalic.Compared with prior art, multifunctional plastic pipe lead bullion propelling pencil of the present utility model only needs the grinding lead for retractable pencil, does not have the problem of disconnected core, and uses the long lead for retractable pencil head of last remaining 20mm, can be used for the lead for retractable pencil of compasses, has improved the utilization rate of lead for retractable pencil greatly.
Description of drawings:
Utilize accompanying drawing to further describe embodiment of the present utility model below;
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two.
The specific embodiment:
Referring to Fig. 1, Fig. 2, this pen has penholder, lead for retractable pencil, principal character is: penholder is to be made of three parts, top is outer loop bar 4, afterbody is equipped with rubber 5, and the bottom is a lead for retractable pencil clamping righting rod 1, and righting rod is sleeved in the outer loop bar 4, hollow part between two bars is provided with lead for retractable pencil clamping pushing ram 3, and the clamping aperture of retaining part is respectively
1.6mm.Lead gripper core dimidiation circle on lead for retractable pencil clamping pushing ram 3, its root is provided with the elasticity card (not shown) that fixes to clamp lead for retractable pencil 2, lead for retractable pencil clamping pushing ram 3 among the embodiment one adopts screw thread pushing ram 3-1, and an end of this bar cooperates screw rod to be provided with nut and revolves a 3-3; Lead for retractable pencil clamping pushing ram 3 among the embodiment two adopts pushes pushing ram 3-2 (referring to Fig. 2), pushing pushing ram 3-2 is provided with and lead for retractable pencil clamping righting rod 1 endoporus interference fits part, when lead for retractable pencil is used bald, take out outer loop bar, the turn nut revolves a 3-3 or pushes pushing ram 3-2, then can lead for retractable pencil be released by lead for retractable pencil clamping pushing ram 3, and with grinding stone or sand paper lead for retractable pencil head grinding-shaping just can be continued to use, use up a lead for retractable pencil, can reuse from more renewing lead for retractable pencil again again.
