[0006] [Patent Document 1] Japanese Patent No. 7465605 Summary of the Invention

[0007] [The problem the invention aims to solve]

[0008] Traditional hand tools lacked design considerations to satisfy hobbyists, making it impossible to experience the joy of ownership or the pleasure of collecting. Furthermore, if a part broke, the entire tool had to be purchased, resulting in a significant financial burden.

[0009] The present invention was made to solve the aforementioned problem, and its purpose is to provide a manual tool that combines design and functionality and allows for parts replacement.

[0010] [Technical means to solve the problem]

[0011] To address the aforementioned issues, the hand tool of the present invention includes: a pair of main body members, each having a working part at a front end and a gripping operation part at a rear end; and a connecting part that supports the pair of main body members in a cross-shaped configuration, enabling them to rotate. The working part is opened and closed by the opening and closing operation of the gripping operation part. In the hand tool, the gripping operation part has decorative and replaceable gripping members, the working part has a pair of working members and a stop-opening mechanism for the working members, mounting holes for fixing the gripping members to the main body members are provided in the pair of main body members and the gripping members, and insertion holes for inserting the front end of the gripping operation part of the main body members into the gripping members are provided in the gripping members.

[0012] Additionally, a mounting member for fixing the holding member to the main body member is inserted through the mounting hole.

[0013] Furthermore, the working part is a pair of blades for performing cutting operations, and the hand tool is a cutting clamp.

[0014] [The effects of the invention]

[0015] According to the present invention, since the gripping member is decorated, not only is its functionality as a tool obtained, but also the pleasure of possession or the enjoyment of collection can be obtained.

[0016] In addition, since the gripping components have a replaceable structure, it is easy to replace parts when damaged, which is economical. Attached Figure Description

[0031] The embodiments of the present invention will now be described. The hand tool of the present invention includes a pair of main body members, each main body member having a working part at its front end and a gripping / operating part at its rear end. The pair of main body members are cross-arranged at a connecting portion and supported to be rotatable.

[0032] The gripping operation section is equipped with a decorative and replaceable gripping component. The gripping component is fixed by a mounting component via mounting holes provided in a pair of main body components and the gripping component.

[0033] The working section has a pair of working components, specifically, when used as a cutting clamp, it is configured as a pair of blades. Furthermore, the working section is equipped with a stop mechanism to ensure that the working section can be stored in a closed state during storage.

[0034] like Figure 1 As shown, the manual tool of this embodiment includes a pair of main body components 10, a holding component 20, and a mounting component 30.

[0035] A pair of main body members 10 have a working section 11 at the front end and a gripping operation section 13 at the rear end. The pair of main body members 10 are cross-arranged at the connecting section 12 and supported to be rotatable. An anti-opening mechanism 14 is provided in the working section 11.

[0036] like Figure 2 As shown, a mounting hole 31 is provided in the gripping operation part 13 of the main body component 10. The mounting hole 31 is used to fix the gripping component 20 to the main body component 10.

[0037] like Figure 3 As shown, the holding member 20 is decorated, and a mounting hole 31 is provided at a position corresponding to the main member 10.

[0038] like Figure 4 As shown, the gripping member 20 is provided with an insertion hole 21. By inserting the front end of the gripping operation part 13 of the main body member 10 into the insertion hole 21, the gripping member 20 can be installed on the gripping operation part 13 of the main body member 10. By inserting the mounting member 30 through each mounting hole 31, the gripping member 20 can be fixed to the main body member 10. With this structure, the gripping member 20 can be easily replaced.

[0039] In this embodiment, the main body component 10 is primarily formed of a metallic material. The gripping component 20 may be formed of a metallic material or a resin material. Examples of metallic materials include stainless steel, aluminum alloy, and titanium alloy. Examples of resin materials include acrylonitrile butadiene styrene (ABS) resin, polycarbonate, and reinforced plastics.

[0040] The decoration of the holding component 20 can be implemented in various forms. For example, examples include: excavation processing to form raised and recessed patterns on the surface, three-dimensional processing to form three-dimensional protrusions or recesses, multi-color coating based on coloring treatment, metallic luster treatment, pattern formation based on laser processing, etching processing, and aluminum oxide film treatment. These decorative processing can be implemented individually or in combination.

[0041] Furthermore, the gripping member 20 may be provided with auxiliary functions. For example, it may have a protrusion that functions as a scraper, a tip that can be used as a screwdriver, or a cutting edge that functions as a wire stripper. Thus, the gripping member 20 can not only have decorative elements but also practical functions.

[0042] The gripping component 20 is available in multiple variations with various shapes and functions, allowing for customization based on user preferences or intended use. For example, it can be configured with gripping components of different sizes to match hand size, curved shapes emphasizing grip comfort, textured shapes that enhance finger hooking, and functions suitable for specific tasks. Thus, users can enjoy multiple gripping components as collectibles.

[0043] The hand tool of the present invention can be applied not only to cutting pliers, but also to various types of hand tools. For example, by changing the shape or function of the working part 11 of pliers, needle-nose pliers, pliers, wire strippers, crimping tools, etc., a wide variety of hand tools can be realized. In this embodiment, cutting pliers are shown as an example, but the invention is not limited to this.

[0044] Furthermore, the present invention is not limited to the described embodiment. For example, various types of components such as screws or pins can be used as mounting members 30. In addition, the structure of the locking mechanism 14 can also be of various forms such as sliding or rotating.

[0045] The hand tool of this embodiment is manufactured through the following steps. First, the main body component 10 is formed from metal material by machining. Next, the gripping component 20 is manufactured from metal material by machining, or from resin material by injection molding. Then, the main body component 10 and the gripping component 20 are mounted by mounting component 30. Finishing may be performed during or after the manufacturing process of the gripping component 20.

[0046] [Industry availability]

[0047] The hand tool of this invention can be used as a functional and decorative tool in various industrial fields such as DIY, electrical engineering, and precision equipment assembly. It is particularly useful in tool markets that value design or collectability. Furthermore, its structure allows for parts replacement, making it highly repairable and maintainable, and suitable for long-term use.
