Description

Pencil with cap and sharpening device

The utility model belongs to schooling apparatus, particularly a kind of apparatus that can sharpen a pencil and can protect pencil.

Pencil is a kind of widely used articles for writing; its cheapness, be convenient to alter and be subjected to liking of user; students in middle and primary schools' one of study article that more is absolutely necessary particularly; but the use pencil needs to sharpen a pencil through pencil-knife commonly used, keeps the taper of nib; and pencil-lead is easy to fracture; also need the cap for brush to protect nib, and pencil, graver, the cap for brush are usually placed, and make troubles to the user respectively.

The purpose of this utility model is to design a kind of Pencil with cap and sharpening device for overcoming the weak point of above-mentioned use pencil, and the cap for brush and pencil sharpener are combined, and is enclosed within on the pencil, carry, easy to use, and economical, economical.

The utility model is designed a kind of Pencil with cap and sharpening device, it is characterized in that, comprise that overcoat, knife rest, pen grab, said knife rest has the sleeve in pyramid type hole in being, one blade is embedded in wherein, and its blade exposes outside the conical bore inwall, and this conical bore butt diameter is corresponding with the pencil external diameter, this sleeve lateral wall axially has an elongated slots in vertical place with blade, and its length and edge length are corresponding; Said overcoat is placed in outside the said knife rest sleeve, and its inwall and sleeve outer wall closely cooperate, and its side-wall shaft has an elongated slots to the position corresponding to the knife rest notch, and its length and said edge length adapt; Said pen is grabbed to the sleeve of a round platform is arranged, and its internal diameter is consistent with the pencil external diameter, and its round platform one end inserts in the said overcoat port, and its other end has a plurality of slits along sidewall, makes it form the multijaw shape.

Each parts of the utility model can adopt the engineering plastics casting, and tight fit is integral mutually, also can adopt other materials to make, and each parts can adopt and be threaded or sealed other connected modes that waits of screw.The utility model also can increase by a hook in the upper end, be convenient to hang.The blade of dress is preferably long oblique triangle shape in the utility model, also can adopt strip or other shapes.The pen grab and can in overcoat, rotate, also can with the overcoat tight fit.

When the utility model uses, be that nib is grabbed insertions from pen,, stretch into gradually in the conical bore of penholder by Propelling pencil with sharpener in cap, pencil shaft by blade cut after, wood is cut from the discharge of overcoat slit mouth, cuts into tapered until pen core, extracts can use.When pencil does not use, can insert the effect of playing the protection nib among the cap cutter.

The utility model is combined as a whole the cap for brush and graver dexterously, both can cut pencil at any time, can be enclosed within again to protect nib to avoid clashing and breaking on the pencil, and economical and beautiful, easy to carry, have very strong practicality.

Brief Description Of Drawings:

Fig. 1 is an embodiment user mode generalized section of the present utility model.

Fig. 2 is each exploded sketch of present embodiment.

A kind of embodiment of the present utility model such as Fig. 1-shown in Figure 2, it is as follows to describe its structure in conjunction with the accompanying drawings in detail:

Fig. 1 is a present embodiment user mode overall package generalized section, and among the figure, a pencil 6 is inserted among the Pencil with cap and sharpening device, and wherein Pencil with cap and sharpening device is by the hook 1 that mutually combines to one, overcoat 2, and knife rest 3, blade 4, pen is grabbed 5 compositions.

Fig. 2 is each modular construction decomposing schematic representation of present embodiment, and among the figure, hook 1 is that a spring steel wire curves half-circle-arc shape, and its inward at both ends bending can be inserted in the circular hole of upper end, overcoat 2 side; Overcoat 2 is a round buss, and its sidewall is opened an elongate slot 21, one side groove is an inclined-plane 22, the internal diameter of sleeve is slightly less than the external diameter of knife rest sleeve, makes it to closely cooperate; The cylinder 3 that knife rest is one of the forming, in a up-small and down-big round taper hole 31 is arranged, one long oblique triangle blade 4 is embedded among the cylinder in advance, blade is exposed outside the circular cone hole wall and with hole inwall keeping parallelism, cylinder side and blade vertical direction are opened an elongated slots, (not shown), its length and blade lengths adapt, and this notch communicates with the overcoat notch; It is a cylinder that pen grabs 5, and outer wall has integrally formed round platform 51, and cylinder is divided into two parts up and down, and its upper port forms a chamfering 52, is convenient to insert in the overcoat, and its underpart upwards evenly has 6 notches 53 along port, makes the bottom form claw-like and is convenient to grasp pencil.During the pencil cutting, pen is caught pencil, can rotate in overcoat.

Each parts of the utility model all adopt the engineering plastics injection molding to form except that hook and blade, during assembling, utilize the mutual tight fit of elasticity of material itself to be integral.
