Description

Technical Field

[0001] The present invention relates to the technical field of cable crimping pliers, in particular to a cable crimping pliers for electric power construction. Background Art

[0002] Wire crimping pliers, also known as wire crimping pliers, are tools used to press crystal heads. When connecting telephone lines, network cables, and cables, you need to use connectors to connect them and fix them together. The cables placed inside the connectors are not firm enough and are easy to loosen, so you need to use wire crimping pliers to clamp the outside of the connectors to prevent them from deforming and to firmly connect the cables.

[0003] In the prior art, a cable crimping pliers for electric power construction with publication number CN 116053880 A includes a pliers body, a first rotating shaft fixedly mounted on the inside of the pliers body, a connecting block fixedly mounted on the outside of the first rotating shaft, and a crimping groove formed on the outside of the connecting block; a first telescopic rod, a rotating block fixedly mounted on the tail end of the first telescopic rod, a third rotating shaft nested inside the rotating block, and the third rotating shaft fixedly mounted on the inside of the pliers body. The cable crimping pliers for electric power construction crimps cables of different diameters by providing multiple groups of adjustable and rotatable crimping grooves, thereby avoiding wear and loss of parts caused by disassembly of the pliers head. A cutter for stripping and cutting wires is provided on the outside of the pliers body to perform operations on the cables, thereby achieving a multiple-function effect. The second telescopic rod is provided with a locking and limiting structure to prevent the inner cutter from causing harm to the human body when not in use. The limiting structure can prevent the second telescopic rods at both ends from being too close to each other and pinching the user.

[0004] However, although the existing cable crimping pliers can well convert and fix cables of different sizes when in use, they still need to be operated with both hands when using the crimping pliers. In cable construction, the crimping pliers need to be used at a higher position. There is insufficient operating space for operating the crimping pliers with both hands, which poses a safety hazard to construction workers. The crimping pliers are not very convenient to operate with one hand, and when operating the crimping pliers with one hand, the dust adsorbed on the surface of the crimping block is not effectively cleaned by simultaneous blowing, which reduces the quality of crimping and fixing of cables of different sizes. At the same time, when converting crimping blocks of different sizes, it is not very convenient to operate the switching component at the handle, which reduces the flexibility of switching crimping blocks of different sizes at high altitudes and does not meet people's usage needs. For this reason, we propose a cable crimping pliers for power construction. Summary of the Invention
