Description

Technical Field

[0001] The utility model relates to the technical field of files, in particular to a file for processing metal parts. Background Art

[0002] As a common hand tool, files are used to trim and process metal, wood and other materials. They have a unique file tooth design that can effectively remove unevenness and burrs on the surface of the material to achieve the required precision and smoothness.

[0003] However, traditional files have some shortcomings during use:

[0004] Safety and portability issues: The blades of most traditional files remain exposed when not in use, which not only increases the risk of damage to the tool, but may also scratch the user or damage other items during carrying or storage.

[0005] Blade fixing and replacement problems: In some file designs, the connection between the blade and the handle is not flexible enough, and the blade replacement process is cumbersome or requires special tools, which reduces the adaptability and economy of the tool.

[0006] Durability and material issues: Traditional files may not use the most optimized materials and surface treatment technology, making the files prone to wear or damage when processing hard metals.

[0007] Therefore, this scheme especially proposes a kind of metal parts processing file, to solve the above problems. Utility Model Content

[0008] In order to overcome the defects of the prior art, the utility model aims to provide a file for processing metal parts.

[0009] To achieve the above-mentioned purpose, the technical solution of the utility model is implemented as follows: a file for processing metal parts, comprising a file blade, the rear end of the file blade is connected to a file blade positioning seat through a plug-in end, a holding handle is arranged on the outside of the file blade positioning seat, a long strip-shaped storage through-hole is arranged on the holding handle, the file blade positioning seat is connected to the holding handle through a rotating shaft arranged at the top position of the storage through-hole, and limiting screws for limiting the rotation of the file blade positioning seat are installed at the front and rear of the holding handle.

[0010] Preferably, a positioning stud is threadedly connected to one side of the file blade positioning seat, and an inner end of the positioning stud penetrates into the file blade positioning seat and is inserted into the inside of the blade positioning groove arranged on the side of the file blade insertion end.

[0011] Preferably, the limiting screw specifically includes the following structure:

[0012] A docking stud screwed onto the side of the grip handle;

[0013] A positioning boss distributed at one end of the inner side of the docking stud, the positioning boss being inserted into the interior of a rotation-limiting positioning groove provided on the same side of the file blade positioning seat;

[0014] A screw cap is installed on one end of the outer side of the butt stud.

[0015] Preferably, the rotating shaft is a damping rotating shaft.

[0016] Preferably, the file blades are of multiple models and have the same internal structure design when inserted into the file blade positioning seat.

[0017] Preferably, the front and rear surfaces of the grip handle are both provided with anti-slip patterns.

[0018] The beneficial effects of the utility model are embodied in:

[0019] Safety and portability: The file blade can be completely screwed into the storage hole in the grip handle, which greatly increases the portability and safety of the product. When not in use, the file blade is completely hidden in the handle, avoiding accidental scratches or damage caused by traditional files due to the blade being exposed to the outside.

[0020] Stable structure and easy operation: The design of the positioning spiral and the rotating shaft ensures the stability of the file blade during use. Users can easily lock or unlock the blade by turning the cap. This user-friendly design makes operation easier while ensuring the accuracy and efficiency of work.

[0021] Versatile and replaceable: The file blade is made of high-hardness tool steel and is suitable for processing various metal materials. The replaceability of the blade allows users to replace different types of blades according to different processing requirements, which improves the applicability and economy of the tool.

[0022] To sum up, this file not only provides efficient working performance, but also takes into account the user's convenience and safety. It can effectively improve the precision and efficiency of metal processing and is a tool with excellent performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] It should be noted that if the utility model embodiments involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0040] Please refer to the instruction manual Figure 1-Figure 7 The utility model provides a file for metal parts processing, including a file blade 1, the tail end of the file blade 1 is connected with a file blade positioning seat 2 through a plug-in end, a holding handle 5 is arranged on the outer side of the file blade positioning seat 2, and a long strip-shaped storage through-hole 6 is arranged on the holding handle 5. The file blade positioning seat 2 is connected to the holding handle 5 through a rotating shaft 3 arranged at the top position of the storage through-hole 6, and limiting screws 4 for limiting the rotation of the file blade positioning seat 2 are installed at the front and rear of the holding handle 5.

[0041] Embodiment 1:

[0042] The file blade 1 is made of high-hardness tool steel material and has fine file teeth, and is suitable for fine processing of various metal materials.

[0058] The shape of the positioning boss 43 matches the rotation-limiting positioning groove 22 , ensuring that the limiting screw 4 can be accurately inserted into and fixed on the file blade positioning seat 2 .

[0059] The screw cap 41 is designed to be easy to operate, so that the user can tighten or loosen it by hand to control the locking and unlocking operations of the file blade positioning seat 2 .

[0060] The rotating shaft 3 is specifically a damping rotating shaft.

[0061] Embodiment 4:

[0062] The resistance of the damping shaft 3 enables the file blade positioning 2 to rotate smoothly.

[0063] The file blade 1 can be provided with multiple models and inserted into the file blade positioning seat 2 with the same internal structure, and is compatible with the file blade positioning seat 2, so that different models of file blades 1 can be easily replaced according to needs.
