Abstract

The utility model relates to a multi-purpose file. A basal body of the file is a shaft, and the section of the part of the shaft for grinding is a polygon. A plurality of sides of the polygon is provided with arced sides and straight sides, wherein, a concave is arranged between two adjacent straight sides, forming a groove on the basal body of the file, and an acute angle is arranged between two adjacent straight sides. The multi-purpose file is applicable to manicuring, grinding fish-hooks, repairing keys, grinding glass holes, grinding platinum of automotive igniters, etc., becoming a necessary article in daily life and a portable tool for electricians and fitters, and the utility model can also be used for carving handicrafts. One multi-purpose file can replace a plurality of kinds of the existing files.

Description

A kind of multipurpose file

The utility model relates to a kind of file, especially a kind of multipurpose file.

File of the prior art generally has only a kind of purposes, and for example, flat file can only be applicable to the filing face, and round file can only be used for filing cambered surface, and triangular file will be used in the file angle, could satisfy different instructions for uses so the user often will prepare some kinds of files.

The purpose of this utility model is to improve the deficiencies in the prior art, but provides a kind of grinding various surfaces, widely applicable multipurpose file.

The purpose of this utility model is achieved in that the matrix of this file is a shaft, the bar cross section that is used as the part of grinding is a polygon, in polygonal some limits, arc limit and straight flange are arranged, constitute a depression between two adjacent straight flanges wherein, and on the file matrix, form a groove.

In described polygonal some limits, folder one acute angle between two adjacent straight flanges can also be arranged.

The file matrix as the surface of the bar of grinding on or make the groove mark that is used for grinding, or by electric plating method on described surface with an abrasive grain layer, described abrasive grain layer can be a layers of diamond particles.

The multipurpose file that the utility model provides is because it has described cross section, make parts such as having plane, cambered surface, groove and fin on the file, but the planar section filing face on the file, cambered surface part on the file can be filed cambered surface, fin on the file can be filed the recess on the part, and the recess that the fin that folder one acute angle constitutes between two adjacent straight flanges is used on the grinding part is just more handy, and the groove on the file can be filed sharp-pointed part or part position.Therefore, this multipurpose file applicable to have a manicure, grind fish hook, repair key, ground glass hole, mill igniter for automobile platinum etc., become the necessary article in the daily life, the carry-on instrument of electrician, pincers worker, even can also be used for the engraving of handicraft.This file can push up existing several file, gives the user with bigger convenience.

Below by drawings and Examples the utility model is elaborated.

The A-A cutaway view of Fig. 2: Fig. 1;

Fig. 3: the front view that the utlity model has another kind of cross sectional shape file;

The B-B cutaway view of Fig. 4: Fig. 3.

Embodiment 1:

As shown in Figure 1, file matrix 1 is divided into two sections, segmentation 1-1 is a circular cross-section, as handle, the cross section of segmentation 1-2 is illustrated in figure 2 as a pentagon, wherein presss from both sides an acute angle between straight flange 1-2-1 and the straight flange 1-2-2, and straight flange 1-2-3 and straight flange 1-2-4 constitute a depression 1-2-5, and on file matrix 1, form a groove 1-3, between straight flange 1-2-4 and the straight flange 1-2-1 circular arc limit 1-2-6.

On the surface of segmentation 1-2, utilize electric plating method to be shaped on a layers of diamond particles 1-4.

Embodiment 2:

As shown in Figure 3, file matrix 2 is divided into two sections, segmentation 2-1 is a circular cross-section, as handle, the cross section of segmentation 2-2 is illustrated in figure 4 as a pentagon, and wherein adjacent straight flange 2-2-1 and straight flange 2-2-2 constitute a depression 2-2-3, and form a groove 2-3 on file matrix 2, the other end at straight flange 2-2-1 and straight flange 2-2-2 respectively has an arc limit 2-2-6 and arc limit 2-2-4, between arc limit 2-2-4 and arc limit 2-2-6 a straight flange 2-2-5 is arranged.
