Abstract

The utility model is related to keyboard foot pad etching cutting knife, including tool rest and bipyramid etching knife, and the tool rest is horizontal cuboid support base, and the bipyramid etching knife is located in the middle part of the tool rest, and the bipyramid etching knife is that hollow flat of the inside and outside with inclined edge is horizontal rectangular.Keyboard foot pad of the present utility model etches cutting knife, etches bipyramid inclined edge, and product tolerance is small, and controllable tolerance is within 0.05mm, and the life-span of cutter is more longlasting, and comprehensive cost performance is high.

Description

Keyboard foot pad etches cutting knife

Technical field

The utility model belongs to the foot pad die-cutting rule of computer fittings technical field, more particularly to keyboard and mouse.

Background technology

The foot pad of the keyboard and mouse of prior art uses die-cutting rule, and product tolerance is bigger than normal, and it is low that product integrates cost performance.

Utility model content

Based on this, for prior art, technical problem to be solved of the present utility model be just to provide a kind of tolerance it is small, The keyboard foot pad etching cutting knife of long lifespan.

The technical solution of the utility model is：

A kind of keyboard foot pad etches cutting knife, including tool rest and bipyramid etching knife, and the tool rest is horizontal cuboid support base, The bipyramid etching knife is located in the middle part of the tool rest, and the bipyramid etching knife is the horizontal frustum of hollow flat of the inside and outside with inclined edge Body.

In one of the embodiments, the bipyramid etching knife includes outer oblique cone blade, fillet sword, interior oblique cone blade and cone Cutting edge, the outer oblique cone blade and the interior oblique cone blade meet at the cone cutting edge of square end faces, and the fillet sword is institute State the inside and outside fillet declivous cutting edge of four angle transition of square.

Compared with the prior art, keyboard foot pad etching cutting knife of the present utility model, etches bipyramid inclined edge, product tolerance is small, can Tolerance is controlled within 0.05mm, the life-span of cutter is more longlasting, comprehensive cost performance is high.

Brief description of the drawings

Fig. 1 is that keyboard foot pad of the present utility model etches cutter structure schematic diagram.

In figure, 10-- tool rests；20-- bipyramid etching knives；The outer oblique cone blades of 21--；22-- fillet swords；Oblique cone knife in 23-- Sword；24-- bores cutting edge.

Embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.It should be noted that not rushing In the case of prominent, the feature in following embodiment and embodiment can be mutually combined.

Fig. 1 gives keyboard foot pad etching cutter structure schematic diagram of the present utility model, as seen from the figure, keyboard foot pad erosion Cutting knife, including tool rest 10 and bipyramid etching knife 20 are carved, tool rest 10 is horizontal cuboid support base, and bipyramid etching knife 20 is located at tool rest 10 middle parts, bipyramid etching knife 20 is the horizontal cone table of hollow flat of the inside and outside with inclined edge.Bipyramid etching knife 20 includes outer oblique cone Blade 21, fillet sword 22, interior oblique cone blade 23 and cone cutting edge 24, outer oblique cone blade 21 and interior oblique cone blade 23 meet at square end The cone cutting edge 24 in face, fillet sword 22 is the inside and outside fillet declivous cutting edge of four angle transition of square.

From the above, it may be appreciated that keyboard foot pad etching cutting knife of the present utility model, etches bipyramid inclined edge, product tolerance is small, controllable Tolerance is within 0.05mm, and the life-span of cutter is more longlasting, and comprehensive cost performance is high.

Embodiment described above only expresses several embodiments of the present utility model, and it describes more specific and detailed, But therefore it can not be interpreted as the limitation to the utility model the scope of the claims.It should be pointed out that for the common of this area For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to In protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
