Description

Technical Field

[0001] This utility model relates to the field of manual tool technology, and more specifically, to variable angle pliers. Background Technology

[0002] In existing technology, the jaws and body of conventional pliers (such as needle-nose pliers, diagonal pliers, wire cutters, etc.) are usually fixedly connected, and their working angle is not adjustable. In working environments with limited operating space (such as inside an engine compartment or in equipment gaps) or where a specific operating angle is required (such as avoiding obstacles), this fixed angle design has significant drawbacks: Inconvenient to operate: Users are often forced to twist their bodies or wrists to adapt to the fixed angle of the pliers, resulting in laborious and inefficient operation.

[0003] Safety hazards: Uncomfortable operating posture or difficulty in accurately positioning the tool can easily lead to tool slippage, workpiece damage, or even personal injury to the user (such as cuts or pinches).

[0004] Tool limitations: A single pair of pliers with a fixed angle is insufficient to meet the needs of various complex working conditions, often requiring the carrying of multiple pairs of pliers with different angles or frequent tool changes. Utility Model Content

[0005] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a variable angle pliers to solve the technical problem mentioned in the background art that the pliers head angle is not easy to adjust.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a variable angle pliers, comprising a pliers body, the pliers body including a pliers head, a pliers body, and a limiting structure, the pliers head and the pliers body being connected by the limiting structure, the limiting structure including a limiting block, an elastic element, and a limiting device, two limiting blocks being provided, and the two limiting blocks being connected by the elastic element, the limiting device including a limiting plate, the limiting plate being fixedly disposed at the bottom of the pliers head and the top of the pliers body, the limiting plate being provided with a biting part that cooperates with the limiting block, the longitudinal section of the limiting block and the biting part being polygonal or gear-shaped, so as to achieve positioning and locking of multiple discrete angles.

[0007] The present invention is further configured such that the limiting plate is provided with a limiting groove in the circumference, and an internal hexagonal nut is provided between the limiting grooves to adjust the effective length of the limiting grooves to limit the maximum rotation angle of the pliers head and limit the rotation range of the pliers head.

[0008] The present invention is further configured such that the elastic element is a spring, and two limiting blocks are respectively connected to the two ends of the spring.

[0009] (III) Beneficial Effects Compared with the prior art, the present invention provides variable angle pliers, which have the following advantages: 1. Flexible adaptation to multiple angles: The working angle of the pliers head can be quickly adjusted according to the working space and operation requirements, easily dealing with complex scenarios that are difficult to access or operate with traditional pliers.

[0010] 2. Quick one-handed adjustment: Angle switching and locking can be completed with just a simple press-rotate-release action, making the operation extremely convenient and efficient without the need for additional tools.

[0011] 3. Stable and reliable locking: Based on the rigid meshing design of polygonal or gear-shaped interlocking teeth and limit blocks, it provides a high rigidity connection in the locked state, effectively preventing accidental angle changes or loosening during operation, and ensuring operational accuracy and force stability.

[0012] 4. High versatility: This angle adjustment mechanism can be widely used in various pliers products (such as needle-nose pliers, diagonal pliers, wire cutters, water pump pliers, etc.), and has broad market application prospects.

[0013] 5. Improve safety and comfort: Reduce awkward operator posture, lower the risk of tool slippage and workpiece damage, and improve operational safety; make operation more effortless and comfortable. Attached Figure Description

[0019] Please see Figures 1-3 A variable-angle pliers includes a pliers body 1, which includes a pliers head 2, a pliers body 3, and a limiting structure 4. The pliers head 2 and the pliers body 3 are connected by the limiting structure 4. The limiting structure 4 includes a limiting block 5, an elastic element 6, and a limiting device. There are two limiting blocks 5, which are connected by the elastic element 6. The limiting device includes a limiting plate 7, which is fixedly installed at the bottom of the pliers head 2. The limiting plate 7 is provided with a biting part 8 that cooperates with the limiting block 5. The longitudinal section of the limiting block 5 and the biting part 8 is polygonal or gear-shaped. In this embodiment, it can be in the form of, for example, hexagonal, octagonal, or gear-shaped. The limiting plate 7 is provided with a limiting groove 9 in the circumference. An internal hexagonal nut 10 is provided between the limiting grooves 9 to adjust the effective length of the limiting groove 9 to limit the maximum rotation angle of the pliers head 2. The elastic element 6 is a spring.

[0020] In this embodiment, during automotive electrical repair, when dealing with a fuse box connection module located in a complex wiring layout and in a live state, in the locked state, under the elastic force of the elastic element 6, the limiting block 5 is tightly engaged in the engagement portion 8 of the limiting plate 7. Through the cooperation of the polygonal or gear-shaped limiting block 5 and the engagement portion 8, the pliers head 2 and the pliers body 3 are firmly locked at the current angle, ensuring a rigid connection during operation.

[0021] More specifically, in the unlocked state for angle adjustment, the user presses the limiting block 5, causing it to squeeze the elastic element 6 and disengage from the engaging portion 8 of the limiting plate 7. At this time, the pliers head 2 can rotate freely around the circular axis of the limiting block 5 to adjust the required working angle. Then, the user releases the pressure, and the limiting block 5 quickly resets under the elastic force of the elastic element 6, re-engaging into the corresponding tooth groove of the engaging portion 8 of the limiting plate 7. This securely locks the pliers head 2 and the pliers body 3 at the new working angle. Finally, the user aligns the pliers head 2 with the fuse box connection point for a safe disconnect operation. If further angle adjustment is needed, the above steps can be repeated.

[0022] In summary, when the entire equipment is in use or operation: In automotive electrical repair, when facing a fuse box connection module located in a complex wiring layout and in a live state, in the locked state, under the elastic force of the elastic element 6, the limiting block 5 is tightly engaged in the engagement part 8 of the limiting plate 7. Through the cooperation of the polygonal or gear-shaped limiting block 5 and the engagement part 8, the clamp head 2 and the clamp body 3 are firmly locked at the current angle, ensuring a rigid connection during operation.

[0023] When in the unlocked state for angle adjustment, the user presses the limiting block 5, causing it to squeeze the elastic element 6 and disengage from the engagement part 8 of the limiting plate 7. At this time, the pliers head 2 can rotate freely around the circular axis of the limiting block 5 to adjust the required working angle. Then, the user releases the pressing operation, and the limiting block 5 quickly resets under the elastic force of the elastic element 6, re-embedding into the corresponding tooth groove of the engagement part 8 of the limiting plate 7, thereby firmly locking the pliers head 2 and the pliers body 3 at the new working angle. Finally, the user aligns the pliers head 2 with the fuse box connection part to perform a safe disconnection operation. If the angle needs to be adjusted again, the above steps can be repeated.
