The utility model is characterized in that: a spring and a plurality of round pointed particles are arranged in the spring holes in the blade holder; a convexity ring cavity is arranged at the lower end of the column cavity; a plurality of straight narrow slots are evenly arranged at the cap body where the convexity ring cavity is positioned. The utility model has the advantages that: the pen cap not only can be used as a blade, but also can be used as the pen cap; when the pen cap is used, the pen point is not broken off by the blades.

Description

The multi-functional cap for brush

The utility model relates to a kind of cap for brush, relates in particular to a kind of cap for brush with penknife, is installed on the head of pen.

Occur a kind of cap for brush with penknife on the market, its structure is: have in a side of the cap for brush and cut a R-joining, the side of cutting a R-joining is provided with the penknife seat, and the tool rest and the cap for brush join together.Described tool rest is equipped with Pencil-sharpening razor blade.Its function is both can be used as penknife usefulness to the cap for brush, can be installed on the head of pen again, is used as the cap for brush and uses.But its shortcoming is: when the cap for brush used, because nib is exerted oneself a little near Pencil-sharpening razor blade, nib will be broken by Pencil-sharpening razor blade.

The purpose of this utility model is to provide a kind of cap for brush, and this cap for brush has penknife equally, and when the cap for brush used, nib can not broken by Pencil-sharpening razor blade.

Pencil lead holder technical scheme of the present utility model is to consider like this: this cap for brush contains cap for brush body, pen clip, have in a side of cap for brush body and to cut a R-joining, the side of cutting a R-joining is provided with the penknife seat, tool rest and cap for brush sports association are integral, and described Pencil-sharpening razor blade is installed on the tool rest by trip bolt; Lower end at the cap body also evenly has some straight slits.At the inner chamber of cap for brush body, be divided into diameter straight cylinder inner chamber, shape with pencil head suitable circular cone inner chamber and the chip-removal hole suitable with the pencil body diameter.It is characterized in that: also be provided with a spring eye in the described penknife seat of a., the opening of described spring eye is positioned at the surface of circular cone inner chamber, and spring is installed in the spring eye, and described spring also is equipped with the protruding grain of round end near an end of spring eye opening part; B. also be provided with the convex surface ring cavity that diameter is slightly less than the straight cylinder intracavity diameter in the lower end of straight cylinder inner chamber; The cap body portion at described convex surface ring cavity place evenly has some straight slits.

When penknife uses,, just can fine away nib as long as pencil is slightly firmly advanced rotatably toward cap for brush inner chamber.Meanwhile, be subjected to the extruding of written cone, protruding grain of round end and spring shrink in spring eye.Sharpen a pencil after the end, remove firmly, be subjected to the elastic force effect of spring, the protruding grain of round end is ejected outside the spring eye, and the cone of nib is separated with the edge of a knife.Simultaneously, the effect of straight slit is that the diameter of convex surface ring cavity can be opened or dwindle, and to clamp the penholder body, penholder neither can be fallen down, and nib can not broken by Pencil-sharpening razor blade.

Fig. 1 is the profile schematic diagram of this cap for brush.

Fig. 2 is the structural representation of this cap for brush.

Fig. 3 is the A-A generalized section among Fig. 2.

Fig. 4 is that the protruding grain of spring, round end is installed on the schematic diagram in the spring eye.

Be described in detail below in conjunction with accompanying drawing.

In Fig. 1 as can be seen, this cap for brush contains cap for brush body 1, pen clip 2, has in a side of cap for brush body and cuts a R-joining, and the side of cutting a R-joining is provided with penknife seat 3, tool rest 3 joins together with cap for brush body 1, and described Pencil-sharpening razor blade 4 is installed on the tool rest 3 by trip bolt 5; Lower end at the cap body also evenly has some straight slits 11.The top of described cap for brush body is equipped with rubber 13.

Fig. 2 is the structural representation of this cap for brush.At the inner chamber of cap for brush body, be divided into diameter straight cylinder inner chamber 9, the shape suitable circular cone inner chamber 8 and the chip-removal hole 14 suitable with the pencil head with the pencil body diameter; Also be provided with a spring eye 6 in the described penknife seat 3, the opening of described spring eye 6 is positioned at the surface of circular cone inner chamber 8.Also be provided with the convex surface ring cavity 10 that diameter is slightly less than straight cylinder inner chamber 9 diameters in the lower end of straight cylinder inner chamber 9; Convex surface ring cavity 10 in the lower end of cap body also evenly has some straight slits 11.

Fig. 3 is the A-A generalized section among Fig. 2.The cap body portion at described convex surface ring cavity 10 places evenly has 4 straight slits 11.The effect of straight slit is that the diameter of convex surface ring cavity 10 can be opened or dwindle, to adapt to the penholder that clamps different-diameter.

Fig. 4 is that the protruding grain 12 of spring 7 and round end is installed on the schematic diagram in the tool rest 3 medi-spring holes 6.In the drawings as can be seen, the protruding grain 12 of round end is installed in the end endoporus of spring 7.When penknife uses,, just can fine away nib as long as pencil is slightly firmly advanced rotatably toward cap for brush inner chamber.Meanwhile, be subjected to the extruding of written cone, protruding grain 12 of round end and spring 7 shrink in spring eye 6.Sharpen a pencil after the end, remove firmly, be subjected to the elastic force effect of spring 7, the protruding grain 12 of round end is ejected outside the spring eye 6, and the cone of nib is separated with the edge of a knife.Nib can not broken by Pencil-sharpening razor blade.
