Description

Technical Field

[0001] The utility model relates to a grinding tool, in particular to a grinding file for shoemaking. Background Art

[0002] During the production and processing of leather shoes, it is often necessary to use glue to bond the leather surface. Since the leather surface is usually a smooth plane, directly bonding the leather surface with glue will have quality problems such as loose bonding. Therefore, when currently bonding the leather surface, it is necessary to first use a grinding tool to grind the to-be-bonded part of the leather surface into a rough hair surface before performing subsequent bonding work. This can effectively improve the firmness of the leather surface bonding.

[0003] Existing grinding tools used in shoe factories typically include a handle and a file blade fixed to the handle. The handle and the file blade are aligned in a straight line. When a leather surface is placed on a horizontal work surface and used with the existing grinding tool, the file blade is difficult to maintain parallelism with the leather surface, making it very inconvenient to operate and affecting the grinding effect. Furthermore, due to structural limitations, the file teeth on the existing grinding tool are fixed in size, making it impossible to select a file blade with different mesh teeth according to actual grinding needs. This limits the applicability of the existing grinding tool. Summary of the Invention

[0004] In order to solve the above deficiencies in the prior art, the utility model aims to provide a shoemaking grinding file to achieve the purpose of improving the grinding effect.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a shoemaking grinding file, comprising a handle component, a connecting component fixedly connected to the handle component, a file seat hinged on the connecting component and capable of being positioned, a first file blade detachably connected to the file seat, and a second file blade and a third file blade housed in the handle component, wherein the second file blade and the third file blade can replace the first file blade and are detachably connected to the file seat; the first file blade, the second file blade and the third file blade respectively have file teeth of different mesh sizes.

[0006] As a limitation of the present invention, the file seat can be hinged on the connecting member through the hinge seat.

[0007] As a further limitation of the present invention, the file holder includes a rectangular plate and a file blade mounting groove provided on the rectangular plate for assembling the first file blade, the second file blade or the third file blade.

[0008] As a further limitation of the present invention, the first file blade is a fine-tooth file blade, the second file blade is a medium-tooth file blade, and the third file blade is a coarse-tooth file blade.

[0009] As a further limitation of the present invention, the handle component includes a handle shell and a handle cover detachably connected to the handle shell, and the first file blade, the second file blade and the third file blade can all be accommodated in the cavity of the handle shell.

[0010] As another limitation of the present invention, an anti-slip rubber layer is provided on the outer side of the handle component.

[0011] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0012] (1) The present invention adopts a structural form that combines a handle member, a connecting member, a file holder, a first file blade, a second file blade, and a third file blade, wherein the file holder and the connecting member can be hinged together in a positionable manner. When in use, the angle between the file holder and the connecting member can be positioned at an appropriate position to meet the user's operating habits and ensure that the first file blade, the second file blade, or the third file blade on the file holder is easily parallel to the leather surface during use, which will facilitate the grinding operation and improve the grinding effect on the leather surface. In addition, the first file blade, the second file blade, and the third file blade each have file teeth of different mesh sizes. When in use, the first file blade, the second file blade, or the third file blade can be selected to be installed on the file holder according to actual use requirements, which can effectively expand the scope of application of the present invention.

[0013] (2) The file holder of the present invention is provided with corresponding file blade mounting grooves, which can ensure that the first file blade, the second file blade or the third file blade is firmly mounted on the file holder, and can effectively improve the stability of the structure of the present invention.

[0014] (3) In the present invention, the first file blade is a fine-tooth file blade, the second file blade is a medium-tooth file blade, and the third file blade is a coarse-tooth file blade, which can meet the use requirements of most situations in shoe production. In actual production, the fine-tooth file blade, medium-tooth file blade or coarse-tooth file blade suitable for the grinding requirements of different leather surfaces can be selected, which can effectively expand the scope of application of the present invention and improve the grinding effect of the present invention on the leather surface.

[0015] (4) The utility model accommodates the first file blade, the second file blade and the third file blade in the cavity of the handle shell, which can effectively improve the rationality and practicality of the structure of the utility model.

[0016] (5) The utility model is provided with an anti-slip rubber layer, which can improve the comfort during use and prevent the hand from falling off during use.

[0017] In summary, the present invention has a reasonable structure, is easy to use, and has strong practicality. When in use, the first file blade, the second file blade, or the third file blade can be parallel to the leather surface, which facilitates the grinding operation and improves the grinding effect on the leather surface. In addition, the first file blade, the second file blade, and the third file blade each have file teeth of different mesh sizes. During use, the first file blade, the second file blade, or the third file blade can be selected to be installed on the file holder according to actual use requirements, which can effectively expand the scope of application of the present invention. The present invention is suitable for use in grinding leather surfaces during shoemaking. BRIEF DESCRIPTION OF THE DRAWINGS
