Description

Technical Field

[0001] The utility model relates to the technical field of hardware tools, in particular to a multifunctional pliers. Background Art

[0002] Pliers are one of the most commonly used tools in the hardware and hand tool industry, and their performance and convenience directly impact work efficiency and user experience. However, traditional pliers, such as electrician's pliers, needle-nose pliers, and diagonal-cutting pliers, suffer from significant drawbacks such as bulk, limited functionality, and portability. These single-function pliers fail to meet the diverse and efficient demands of modern work environments, causing significant inconvenience for users.

[0003] To address these issues, folding pliers have gradually emerged on the market. These pliers can be folded up when not in use, significantly reducing their size and making them easier to carry and store. However, existing folding pliers still face several technical challenges. First, although the folding design reduces their size, most multifunctional pliers only have two lever arms, resulting in a limited number of internally connected tool parts. Furthermore, due to size constraints, key tools such as scissors are often small in size, resulting in significant limitations in use and a limited scope of application.

[0004] Secondly, if existing folding pliers are not properly retracted after folding, they can easily become loose or open, which not only affects their effectiveness but also poses a safety hazard. Furthermore, the folding structure of some pliers is not compact enough, making them prone to accidental unfolding due to external forces during portability, increasing inconvenience and potential risks. Utility Model Content

[0005] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides a multifunctional pliers that can solve the problem of scissors or pliers being too small, and can effectively provide users with a positioning prompt to avoid potential risks caused by the tools not being fully retracted.

[0006] The technical solution adopted by the present invention to solve the problem is:

[0007] A multifunctional pliers comprises: a first lever arm, wherein the first lever arm has a first storage cavity, and one end of the first lever arm is rotatably connected to a first clamp; a second lever arm, wherein the second lever arm has a second storage cavity, one end of the second lever arm is rotatably connected to a second clamp, the first clamp and the second clamp are rotatably connected, and the other end of the second lever arm is rotatably connected to a first scissors head; a third lever arm, wherein the third lever arm has a third storage cavity, one end of the third lever arm is rotatably connected to a second scissors head, and the first scissors head and the second scissors head are rotatably connected; the second lever arm is rotatably receivable in the first storage cavity, the first lever arm and the second scissors head are rotatably receivable in the second storage cavity, and the first scissors head is rotatably receivable in the third storage cavity; a positioning prompt mechanism is provided between the second lever arm and the first storage cavity, and / or a positioning prompt mechanism is provided between the first lever arm and the second scissors head and the second storage cavity, and / or a positioning prompt mechanism is provided between the first scissors head and the third storage cavity.

[0008] By adopting this solution, the scissors consist of a first scissor head and a second scissor head, and the pliers consist of a first jaw and a second jaw, each located on opposing lever arms. This allows the scissors and pliers to have a wide opening angle and sufficient length when unfolded, thereby improving their flexibility and applicability. By providing a positioning indicator between the lever arm and the storage cavity, the user can clearly sense whether the lever arm is properly stored during the folding process. This design helps prevent the tool from automatically opening or loosening due to improper folding, thereby improving safety and stability.

[0009] Furthermore, the locking prompt mechanism includes a spherical protrusion structure and a locking structure locked with the spherical protrusion structure, and the locking structure is locked with the spherical protrusion structure in a one-to-one correspondence.

[0010] By adopting the above solution, it is ensured that the components can be accurately stored in their respective storage cavities and reach a stable state.

[0011] Furthermore, the locking structure is a groove-shaped structure or a hole-shaped structure.

[0012] By adopting the above solution, the groove-shaped structure can provide higher connection stability, ensuring that the pliers tools will not loosen or shift during use. The spherical protrusion structure can form a sound prompt between the groove, which is convenient for prompting the user to snap into place; the hole-shaped structure can provide higher structural rigidity, making the pliers tools more stable and reliable during use, and easier to produce. The user can intuitively obtain prompts through visual senses, which is convenient for prompting the user to snap into place.

[0013] Furthermore, the end of the first lever arm is rotatably connected to at least one functional component, and / or the end of the second lever arm is rotatably connected to at least one functional component, and / or the end of the third lever arm is rotatably connected to at least one functional component.

[0014] By adopting the above solution, users can quickly switch between different tool functions according to specific needs, thereby improving work efficiency and convenience.

[0015] Furthermore, the functional part is a saw, a cutting knife, a cutter, a screwdriver, a file, a lifter, a bottle opener, a can opener or a handcuff key.

[0016] By adopting the above solution, the needs of life and special equipment can be met.

[0017] Furthermore, a positioning prompt mechanism is provided between the functional component and the first storage cavity, the second storage cavity or the third storage cavity.

[0018] By adopting the above solution, it is possible to clearly understand whether the functional parts have been correctly installed, thereby avoiding usage problems or safety hazards caused by improper installation.

[0019] Furthermore, a partition plate is provided in the first storage cavity, and / or a partition plate is provided in the second storage cavity, and / or a partition plate is provided in the third storage cavity.

[0020] By adopting the above solution, the functional parts, scissors and pliers can be separated from each other to achieve a limiting effect.

[0021] Furthermore, the partition plate includes a transverse partition plate and / or a longitudinal partition plate, and the axial direction of the rotating shaft of the rotation connection is set as the first direction. The transverse partition plate is used to divide the first storage cavity, the second storage cavity or the third storage cavity along the vertical direction of the first direction, and the longitudinal partition plate is used to divide the first storage cavity, the second storage cavity or the third storage cavity along the first direction.

[0022] By adopting the above solution, the layout of the storage cavity can be freely adjusted according to actual needs to accommodate functional parts of different shapes, sizes and quantities; making the storage and access of functional parts more convenient and quick, users can find the required functional parts in a short time, thereby improving work efficiency; the partition plate can also protect the functional parts to prevent them from colliding with each other or being damaged during movement or carrying.

[0023] Furthermore, a scale is provided on the edge of the first lever arm, the second lever arm or the third lever arm.

[0024] By adopting the above solution, the addition of the ruler enables the multifunctional pliers to also have a measuring function. When used, measurements can be performed anytime and anywhere without adjusting the tool position or looking for other measuring tools, which greatly improves work efficiency.

[0025] Furthermore, a belt clip is provided on the first lever arm, the second lever arm or the third lever arm.

[0026] By adopting the above solution, the user can more conveniently fix the pliers on a belt, a backpack strap or other similar locations, so that the pliers are easy to carry and use at any time.

[0027] In summary, the multifunctional pliers provided by the present invention have the following technical effects:

[0028] 1. By dividing the scissors into a first scissor head and a second scissor head with different lever arms, and dividing the pliers into a first jaw and a second jaw with different lever arms, the scissors and pliers can have a wider opening angle and sufficient length when unfolded. This greatly improves the flexibility of the tools and enables them to adapt to more diverse work scenarios and needs;

[0029] 2. Although the size of the scissors and pliers has been optimized, the entire tool can still be significantly reduced in size through a foldable design when not in use. This portability allows users to easily put the tool into a pocket, tool bag or backpack for easy carry and ready access at any time;

[0030] 3. By providing a positioning indicator between the lever arm and the storage cavity, the user can clearly sense whether the lever arm is properly stored. This design effectively avoids the problem of the tool automatically opening or loosening due to improper folding, reduces potential risks during use, and improves tool safety.
