Abstract

The utility model relates to a file used for a shoe tree. The file is composed of a handle and a file face. The handle comprises a grabbing handle and a pressing handle, and the file face is divided into a first segment, a second segment, a third segment and a fourth segment, the first segment is provided with an extending part, the fourth segment is provided with a connecting rod, and a long hole is formed in the grabbing handle. The first segment, the second segment, the third segment and the fourth segment are integrated, the grabbing handle is connected with the fourth segment through the connecting rod, and the extending part is wrapped by the pressing handle. The file is characterized in that the shapes of the sections of the first segment, the second segment, the third segment and the fourth segment of the file are different, the section of the first segment is in a small oval shape, the section of the second segment is in a big oval shape, and the section of the four segment is in a trapezoid shape; protrusive particles are arranged on the surfaces of the first segment, the second segment, the third segment and the fourth segment of the file face, become bigger from the first segment to the fourth segment and become scattered from the first segment to the fourth segment, the particles are triangular bodies, one face of each triangular body is connected with the surface of the file face, and the other face of each triangular body is inclined toward the front end of the first segment. One-point supporting of a file in the prior art is changed to be two-point supporting, the single pattern of the filing face is changed, filing patterns various in shape are distributed in a segmented mode, and therefore the filing effect of different cambered surfaces is achieved.

Description

A kind of file for shoe tree

Technical field

The utility model belongs to shoe last designing and manufacture technology field, relates to specifically a kind of design and manufacture of shoe tree file.

Background technology

File is a kind of manual instrument, for the surface of filing article, to reach required design shape or to carry out trickle finishing, so require file to have curved surface or filing surface ability.And then, on market, there is the file of various kinds, for example: flat file, square file, round file etc., to be applicable to the processing of various article.

In the time that reality is used file, because shoe tree is a kind of irregular 3-D solid structure, there are many different curved surfaces, so often need to use the file of different cultivars, utilize its unique cut of file and file shape, make shoe tree reach designed shape.But the file using for shoe last designing of selling on market is now very rare, only shoe tree file often only just designs a kind of shoe last or hat block type, cannot reach the function general to various shoe trees.Every kind of file all independently arranges, and has not only increased manufacturing cost, and in the time of practical operation, needs constantly to substitute file, and expend energy on expends time in again, has limited to a certain extent the lifting of operating efficiency.

Utility model content

For the deficiencies in the prior art, the purpose of this utility model is: a kind of design for shoe tree file and manufacture are provided, change the single structure of traditional file, in handle of a knife design, retain lever and increase a pressure handle, change a bit supporting of file in the past, change 2 supporting constructions into, realize handled easily.Meanwhile, change the single lines of filing face, distributed by the cut of file segmentation of various shape, large or fine granule in tandem, to reach the best filing effect of different curve.

For achieving the above object, a kind of file for shoe tree is provided, formed by handle and knife face, wherein, handle comprises lever and pressure handle, knife face is divided into: one section, two sections, three sections, four sections, one section has an extension, four sections have a connecting rod, in lever, there is slotted hole, one section, two sections, three sections, four sections as a whole, it is trapezoidal that front is, lever is connected with four sections by connecting rod, pressure handle is wrapped on extension, one section of knife face, two sections, three sections, the section shape difference of four sections, one section is little ellipse, two sections is large oval, four sections is trapezoidal, one section of knife face, two sections, three sections, four section surfaces have protruding particle, particle is ascending to four sections from one section, by close to dredge, particle is triangle body, a face is connected with file surface, another tilts towards one section of front end.

In preferred technique scheme, three segment lengths of described knife face are 15mm, and the thickest position is 5mm, meet the filing demand of last surface.

In preferred technique scheme, four segment lengths of described knife face are 10mm, and section is trapezoidal, are mainly used in the processing of facing directly of shoe tree, and on it, hem width is 3mm-4mm, and lower hem width is 5mm-8mm.

Wherein, one section, two sections, three sections, four sections connections are gradual change form.

In preferred technique scheme, described particle entirety is oblique parallel arranges, vertical with people's power thrusts in the time operating, thereby improves filing effect.

Detailed description of the invention

Now by reference to the accompanying drawings and specific embodiment, the utility model is further illustrated.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, a kind of file for shoe tree, formed by handle and knife face 1, wherein, handle comprises lever 21 and pressure handle 22, knife face 1 is divided into: one section 11, two section 12, three section 13, four section 14, there is an extension 111 for one section 11, there is a connecting rod 141 for four section 14, in lever 21, have 211, a section 11 of slotted hole, two section 12, three section 13, four section 14 as a whole, it is trapezoidal that front is, lever 21 is connected with four section 14 by connecting rod 141, and pressure handle 22 is wrapped on extension 111.

Wherein, the section shape difference of one section 11, two section 12, three section 13, four section 14, one section 11 be little ellipse, two section 12 for large oval, four section 14 for trapezoidal, there is protruding particle 3 on one section 11, two section 12, three section 13, four section 14 surface, particle 3 is ascending from one section 11 to four section 14, and by close, to dredging, particle 3 is triangle body, one of them face 31 is connected with knife face 1 surface, and another face 32 tilts to one section of 11 front end.

Specifically, three section of 13 length of knife face 1 is 15mm, and the thickest position is 5mm, four section of 14 length of knife face 1 is 10mm, and the trapezoidal top 141 of section is wide is 3mm-4mm, following 142 wide be 5mm-8mm, wherein, one section 11, two section 12, three section 13, four section 14 connection is gradual change form.

Further illustrate, particle 3 entirety on knife face 1 surface are oblique parallel and arrange.

More than illustrate the utility model just illustrative; and nonrestrictive, those of ordinary skill in the art understand, in the case of not departing from the spirit and scope that claim limits; can make many amendments, variation or equivalence, but within all falling into protection domain of the present utility model.
