Abstract
A kind of metal-back pencil, comprise metal-back and pencil-lead, it is characterized in that, described metal-back is that form of a stroke or a combination of strokes hollow metal material is made, the face of cylinder of metal-back has the through hole window run through, metal-back is provided with hold-fast ring near one end of nib, and metal-back has expansion groove between through hole window and hold-fast ring, and described pencil-lead matched in clearance to be inserted in metal-back and to be stepped up by hold-fast ring.Structural design is simple, is applicable to batch production, fully can uses up a pencil-lead, metal-back can reuse, environmental protection.
Description
Technical field
The utility model relates to a kind of pencil, particularly a kind of metal-back pencil.
Background technology
At present, the wide variety of pencil, but the design lacking that pencil-lead just can fully use up by a kind of simple structure, so need a kind of simplicity of design badly, can change again and fully use up the durable pencil of pencil-lead.
Summary of the invention
In order to overcome above defect, the technical problems to be solved in the utility model is: propose a kind of metal-back pencil.
It is a kind of metal-back pencil that the utility model solves the technical scheme that its technical problem adopts, comprise metal-back and pencil-lead, it is characterized in that, described metal-back is that form of a stroke or a combination of strokes hollow metal material is made, the face of cylinder of metal-back has the through hole window run through, metal-back is provided with hold-fast ring near one end of nib, and metal-back has expansion groove between through hole window and hold-fast ring, and described pencil-lead matched in clearance to be inserted in metal-back and to be stepped up by hold-fast ring.
Further, described expansion groove is communicated with through hole window and hold-fast ring is split two halves, namely expands the housing dimidiation that groove makes the most advanced and sophisticated one end of metal-back.
The beneficial effects of the utility model are: structural design is simple, are applicable to batch production, fully can use up a pencil-lead, metal-back can reuse, environmental protection.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is top view of the present utility model.
1. metal-backs in figure, 11. through hole windows, 12. expansion grooves, 13. hold-fast rings, 2. pencil-lead.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figure 1 to Figure 3, a kind of metal-back pencil, comprise metal-back 1 and pencil-lead 2, it is characterized in that, described metal-back 1 is made for form of a stroke or a combination of strokes hollow metal material, and the face of cylinder of metal-back 1 has the through hole window 11 run through, metal-back 1 is provided with hold-fast ring 13 near one end of nib, metal-back 1 has an expansion groove 12 between through hole window 11 and hold-fast ring 13, and described pencil-lead 2 matched in clearance to be inserted in metal-back 1 and to be stepped up by hold-fast ring 13.
Described expansion groove 12 is communicated with through hole window 11 and hold-fast ring 13 is split two halves, namely expands the housing dimidiation that groove 12 makes the most advanced and sophisticated one end of metal-back 1.
The service condition of observing pencil-lead 2 is convenient in the design of described through hole window 11; Being designed for of described expansion groove 12 makes metal-back 1 nib one end expand to allow pencil-lead 2 to move, and being designed for of described hold-fast ring 13 steps up pencil-lead 2.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
