Description

An adjustable carp claw Technical Field

[0001] This utility model relates to the field of carp pliers technology, and in particular to an adjustable carp pliers. Background Technology

[0002] Carp pliers, named for their resemblance to a carp, are a very common tool in the hardware industry. Primarily used for gripping round parts, they are versatile and can even replace a wrench to tighten small nuts and bolts when necessary. Their carefully designed cutting edges at the rear of the jaws enable them to cut metal wire, facilitating various operations. The key to the excellent gripping ability of carp pliers lies in the opening size of their jaws, their unique shape, and the leverage effect provided by the pliers themselves.

[0003] In the current technological context, various workpieces exhibit significant characteristics such as diverse materials, varying sizes, and different shapes, resulting in vastly different clamping force requirements. However, traditional pliers rely solely on the operator's hand strength to control the output force. This single control method is often difficult to adapt precisely to different workpieces, easily leading to improper force application, workpiece damage, affecting work quality, and potentially causing unnecessary economic losses.

[0004] To address this issue, we propose an adjustable carp clamp to solve the problem in existing carp clamps that cannot flexibly adjust torque according to the type of workpiece, thus causing damage to the workpiece. Summary of the Invention

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0030] Please refer to Figures 1 to 5. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0031] As shown in Figures 1-5, this utility model provides an adjustable carp pliers, including: a pliers body 1, an adjusting shaft assembly 2, and two connecting assemblies 3.

[0032] The clamp body 1 includes two long arms 10, two handles 11, and two clamp heads 12. Each end of each long arm 10 is connected to a handle 11 and a clamp head 12, respectively. The structure is designed to be longer in the middle and shorter on both sides.

[0033] The adjusting shaft assembly 2 includes slide grooves 20 disposed on the inner sides of the two long arms 10. Each slide groove 20 has a slider 21 inside, and each slider 21 can slide within the corresponding slide groove 20. A rotating shaft 22 connects the two sliders 21, with both ends of the rotating shaft 22 passing through the two sliders 21 and rotatably connected to them. Both ends of the rotating shaft 22 are elastically connected to locking blocks 23. Pull rings are provided on the outer walls of the locking blocks 23, facilitating the pulling of the locking blocks 23 outwards. Several locking grooves 24 that match the locking blocks 23 are provided on the outer walls of the two long arms 10. In use, by pulling the two locking blocks 23 outwards, the locking blocks 23 disengage from the locking slots 24, releasing the lock on the sliders 21. Dragging the locking blocks 23 causes the two sliders 21 to move horizontally within the corresponding slide grooves 20 via the rotating shaft 22, changing the position of the rotating shaft 22 on the two long arms 10. After moving to the designated position, the locking blocks 23 are released, causing them to spring back into the slide grooves 20, locking the position of the rotating shaft 22. This structure, by adjusting the position of the rotating shaft 22, changes the lever ratio of the pliers, thereby adjusting the torque output capability of the pliers. This allows the pliers to adapt to different force requirements, improving work efficiency, enhancing operational flexibility, and protecting the workpiece and tools.

[0034] Each connecting component 3 is located between a long arm 10 and a pliers head 12. The pliers head 12 and the long arm 10 are detachable, allowing the pliers to easily replace different types of pliers head 12, such as needle-nose pliers head 12, diagonal pliers head 12, wire stripper head 12, etc. This gives the pliers multiple functions, meeting different work needs and improving tool utilization.

[0035] In one embodiment, each groove 20 is parallel to the long side of the corresponding long arm 10, and the slider 21 is designed with a square structure to improve the stability of the slider 21 sliding within the groove 20. The slider 21 drives the rotating shaft 22 to slide within the groove 20, adjusting the horizontal position of the rotating shaft 22 on the long arm 10, thereby changing the lever ratio.

[0036] In one embodiment, both ends of the rotating shaft 22 are provided with slide rods 25. Both slide rods 25 pass through the side wall of the rotating shaft 22 and are connected to the middle of the locking block 23. Both slide rods 25 and located inside the rotating shaft 22 are fitted with springs 26. By pulling the locking block 23, the slide rods 25 can be moved outward along the long side of the rotating shaft 22, causing the locking block 23 to disengage from the locking slot 24, and at the same time, the springs 26 are compressed. The springs 26 cooperate with the slide rods 25 to reset the locking block 23 when there is no external force.

[0037] In one embodiment, the two long arms 10 are staggered, and each of the two long arms 10 has a positioning block 27 on its opposing side. The opposing sides of the two long arms 10 also have positioning grooves 28 that match the positioning blocks 27. When adjusting the rotating shaft 22, the two long arms 10 need to be adjusted to a parallel position so that the positioning blocks 27 on one long arm 10 engage with the positioning grooves 28 of the other long arm 10. This restricts the two long arms 10 and prevents misalignment, which could cause the clamp heads 12 to malfunction and affect the operational efficiency.

[0038] In one embodiment, the connecting assembly 3 includes a screw 30 connected to two pliers heads 12, and each end of the two long arms 10 is provided with a screw hole 31 that matches the screw 30. The pliers heads 12 and the long arms 10 are connected by a threaded connection, which is tight and facilitates the disassembly and replacement of different types of pliers heads 12. This structure allows the pliers to meet different work requirements and improves the utilization rate of the tool.

[0039] In one embodiment, the connecting assembly 3 further includes insert blocks 32 disposed at the ends of the two long arms 10, with the insert blocks 32 located around the screw holes 31. Each insert block 32 can slide on the corresponding long arm 10 and penetrate the side wall of the long arm 10. The side walls of the two pliers 12 are each provided with slots 33 that match the insert blocks 32. A spring 34 connects the side wall of the insert block 32 to the long arm 10. During the installation of the pliers 12, the insert blocks 32 are moved by hand to retract into the long arm 10, compressing the spring 34. After the pliers 12 is installed, the insert blocks 32 are released, allowing the insert blocks 32 to be inserted into the pliers 12 under the action of the spring 34, thus restricting the pliers 12, preventing the pliers 12 from rotating, and improving the stability of the pliers 12 connection.

[0040] The specific usage process of this utility model is as follows: Adjust the two long arms 10 to be parallel, so that the positioning block 27 is inserted into the positioning groove 28 to fix the two long arms 10 together. Pull the two locking blocks 23 outward to disengage the locking blocks 23 from the locking grooves 24 of the long arms 10. Push the rotating shaft 22 through the locking blocks 23, so that the rotating shaft 22 drives the two sliders 21 to slide in the sliding grooves 20 of the two long arms 10. Adjust the position of the rotating shaft 22 in the two long arms 10. After reaching the designated position, release the locking blocks 23. Under the action of the spring 26, the locking blocks 23 are reset and re-inserted into the locking groove 24 at the near end to lock the rotating shaft 22, thus completing the adjustment of the lever ratio of the carp pliers.

[0041] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
