Description

Technical field

[0001] The present utility model relates to the technical field of hand tools, in particular to angle-variable pliers. State of the art

[0002] In the prior art, the head and body of conventional pliers (such as needle-nose pliers, slant pliers, steel wire cutters, etc.) are usually fixed together, so that the working angle is not adjustable. In operating environments with limited space (e.g., inside the engine compartment, between devices) or at specific operating angles (e.g., to avoid obstacles), this fixed-angle design has significant disadvantages: 1. Inconvenient operation: Users are often forced to twist their body or wrists to fit the fixed-angle pliers, resulting in cumbersome and inefficient operation. 2. Safety risks: The operating posture is uncomfortable or the tool is difficult to position precisely, which can easily lead to the tool slipping, damage to the workpiece and possibly even personal injury to the user (e.g. scratches, pinching). 3. Limitations of the tool: Pliers with a fixed angle are difficult to meet the requirements of a variety of complex working conditions, so it is often necessary to carry several pliers with different angles or to frequently change tools. Content of the present utility model(I) Technical problems to be solved

[0003] In view of the problems existing in the prior art, the present utility model provides an angle-variable pliers to solve the technical problem of the inconvenient adjustment of the angle of the pliers head mentioned in the background technology. (II) Technical solutions

[0007] In comparison to the prior art, the angle-variable pliers according to the present utility model have the following advantageous effects: 1. Flexible adjustment from multiple angles: The working angle of the pliers head can be quickly adjusted according to the workspace and operational requirements to easily handle complex scenarios where conventional pliers are difficult to reach or operate. 2. Quick one-handed adjustment: Angle switching and locking is achieved by simply pushing, turning and releasing, making operation extremely convenient and efficient without the need for additional tools. 3. Stable and reliable locking: The rigid engagement design of the polygonal or gear-shaped engagement section with the limiting block creates a highly rigid connection in the locked state, effectively preventing unintentional angular changes or loosening during operation to ensure operational accuracy and force application stability. 4. Strong versatility: The angle adjustment mechanism can be widely used in various pliers products (such as needle-nose pliers, slant pliers, steel wire pliers, water pump pliers, etc.) which have broad market application prospects. 5. Increased safety and comfort: This reduces the operator's uncomfortable posture, decreases the risk of tool slippage and workpiece damage, and improves workplace safety, making operation more labor-saving and comfortable.

[0009] It should be noted that the embodiments in the present application and the features in the embodiments can be combined without conflict. The present utility model is described in more detail below with reference to the drawings and in conjunction with the embodiments.

[0010] It should be noted that all technical and scientific terms used in the present application have the same meaning as they are normally understood by a person skilled in the field to which the present application belongs, unless otherwise stated.

[0011] In this utility model, unless otherwise specified, orientations such as "top" and "bottom" generally refer to the directions shown in the drawings or to the vertical, perpendicular, or gravity direction. Similarly, for ease of understanding and description, the terms "left" and "right" generally refer to the left and right depicted in the drawings, and "inside" and "outside" refer to the inside and outside with respect to the contour of the respective components themselves. However, the aforementioned directional terms do not serve to limit the scope of this utility model.

[0012] Angle-variable pliers with a pliers body 1, wherein the pliers body 1 comprises a pliers head 2, a pliers body 3 and a limiting structure 4, wherein the pliers head 2 is connected to the pliers body 3 via a limiting structure 4, wherein the limiting structure 4 comprises a limiting block 5, an elastic part 6 and a limiting device, wherein two limiting blocks 5 are provided, wherein the two limiting blocks 5 are connected to each other by an elastic part 6, wherein the limiting device has a limiting plate 7, wherein the limiting plate 7 is fixedly arranged on the underside of the pliers head 2, wherein the limiting plate 7 is provided with an engagement section 8 for interacting with the limiting block 5, wherein the longitudinal section of the limiting block 5 and the engagement section 8 is polygonal or gear-shaped.wherein in the present embodiment specific shapes such as hexagonal, octagonal or gear-shaped shapes can be assumed, wherein a limiting groove 9 is arranged along the circumferential direction of the limiting plate 7, wherein an internal hexagon nut 10 is arranged between the limiting grooves 9, wherein the elastic part 6 acts as a spring, with reference to , Fig. 1 to Fig. 3.

[0013] In the present embodiment, a fuse box connection module, located within a complex wiring configuration and under voltage, is used for the electrical maintenance of a motor vehicle. In the locked position, the limiting block 5 engages firmly within the engagement section 8 of the limiting plate 7 under the elastic force of the elastic part 6. Through the interaction of the polygonal or gear-shaped limiting block 5 and the engagement section 8, the clamping head 2 is firmly locked to the clamping body 3 at the current angle to ensure a rigid connection during operation. More precisely, in the unlocked position of the angle adjustment, the user presses the limiting block 5, causing the limiting block 5 to press the elastic part 6, thus releasing the limiting block 5 from the engagement section 8 of the limiting plate 7.At this point, the plier head 2 is freely rotatable around the circular shaft section of the limiting block 5 to adjust the desired working angle of the plier head 2. After the pressure is released, the limiting block 5 is rapidly reset under the elastic force of the elastic part 6, so that it is once again embedded in the corresponding toothed grooves of the engagement section 8 of the limiting plate 7, thereby firmly locking the plier head 2 to the plier body 3 at a new working angle. Finally, the fuse box connection is aligned via the plier head 2 to perform a secure disconnection operation. If the angle needs to be readjusted, the above steps can be repeated.

[0014] In summary, when using or operating the entire equipment: During the electrical maintenance of a motor vehicle, a fuse box connection module is used, which is located in a complex wiring configuration and is live. In the locked state, the limiting block 5 engages firmly under the elastic force of the elastic part 6 within the engagement section 8 of the limiting plate 7. Through the interaction of the polygonal or gear-shaped limiting block 5 and the engagement section 8, the clamping head 2 is firmly locked to the clamping body 3 at the current angle to ensure a rigid connection during operation.

[0015] With the angle adjustment unlocked, the user presses the limiting block 5, causing it to press the elastic part 6 and release the limiting block 5 from the engagement section 8 of the limiting plate 7. At this point, the plier head 2 is freely rotatable around the circular shaft section of the limiting block 5 to adjust the desired working angle. After the pressure is released, the limiting block 5 is rapidly reset by the elastic force of the elastic part 6, so that it is once again engaged in the corresponding toothed grooves of the engagement section 8 of the limiting plate 7, thus firmly locking the plier head 2 to the plier body 3 at the new working angle. Finally, the fuse box connection is aligned over the plier head 2 to perform a secure disconnection operation.If the angle needs to be adjusted again, the steps above can be repeated.
