Description

Technical Field

[0001] The utility model relates to the technical field of carp pliers, in particular to a pair of carp pliers with a quick resetting function. Background Art

[0002] Slip joint pliers, named after their carp-like appearance, are a tool widely used in the auto repair industry and daily maintenance operations. They have a unique jaw design, and the opening width of the jaws can be adjusted to two levels, so that the pliers can be enlarged to accommodate large round parts, or reduced to clamp small objects. In addition to clamping round parts, pliers are often used as a substitute for wrenches to tighten small nuts and bolts, and even the cutting edge at the back of the jaws can be used to cut wires. They are versatile and practical.

[0003] However, despite the powerful functions of the carp joint pliers, their operation methods have obvious shortcomings in actual use. First, when the carp joint pliers clamp bolts or nuts, the opening and closing of the jaws are completely dependent on the manual control of the operator. To ensure that the bolts or nuts do not slip or fall off during the clamping process, the operator must maintain a certain grip force. This long-term manual control not only increases the labor intensity of the operator, but also easily leads to hand muscle fatigue, and even stiffness and weakness, which greatly reduces work efficiency and operating comfort.

[0004] Secondly, after use, the carp joint pliers usually need to be reset for storage and next use. However, the existing carp joint pliers reset process still relies on manual operation. This means that the operator needs to manually reset the carp joint pliers after each use. This reset method is not only inefficient, but also in some cases, such as when the operator is tired or distracted, it may lead to incomplete or failed reset, thus affecting the storage of the carp joint pliers and the effect of the next use. At the same time, because the pliers head is prone to wear or damage during use, traditional pliers usually need to be replaced as a whole once damaged, which increases the cost of use. In addition, according to different work scenarios and needs, users also need to carry carp joint pliers with pliers heads of different materials or specifications for replacement, which is too troublesome and cumbersome.
