Description

Technical Field

[0001] The utility model relates to a wire clamping device, in particular to a wire clamping device for preventing wire deformation, belonging to the technical field of wire clamping devices. Background Art

[0002] In the prior art, a large-section expanded-diameter wire clamping device is disclosed in the utility model with the application number 202321419841.7. In order to solve the problem that the clamping range is usually relatively small, and it can only clamp common ordinary wires, but it is not applicable to large-section expanded-diameter wires, and the problem that the function of tightly clamping large-section expanded-diameter wires cannot be effectively realized. By installing a clamping rod and a mounting clamping hole and cooperating with two groups of first connecting nuts, the upper clamping plate is clamped at different positions on the rotating rod. Then, through the cooperation of the rotating plate and the first shaft rod with the connecting plate, the moving rod and the first sliding opening on the second shaft rod, the rotating rod rotates stably relative to the main body. Thus, under the cooperation of the sliding rod and the second sliding opening, the upper clamping plate continuously moves towards the lower clamping plate until the upper clamping plate and the lower clamping plate tightly clamp the large-section expanded-diameter wire. Then, through the connecting hinge, the movable plate rotates, and under the cooperation of the long bolt and the connecting clamping hole, the movable plate is clamped with the rotating rod to fix the relative positions of the upper clamping plate and the lower clamping plate, which can quickly and effectively tightly clamp wires with different outer diameters, increase the clamping range, and has good applicability.

[0003] The current situation similar to the above application still has deficiencies:

[0004] When the inside of the clamping mouth is damaged, in order to avoid wire deformation during use, it is necessary to replace the pliers arm or the device. Although the above device can install and disassemble the pliers arm by using the cooperation of the connecting nut and the connecting rod, it requires special tools for installation and disassembly, and when the teeth inside the clamping mouth are damaged, the entire pliers arm needs to be replaced, resulting in a high use cost and low practicability;

[0005] Therefore, a wire clamping device for preventing wire deformation is designed to optimize the above problems. Content of the Utility Model

During the clamping process of the clamping openings on the first clamping plate 7 and the second clamping plate 13, they can closely fit with the wire, effectively avoiding wire deformation during the pressing process. And when the tooth teeth inside the clamping opening are damaged, the clamping plates can also be replaced. In addition, during the installation process of the first clamping plate 7 and the second clamping plate 13, they are respectively inserted into the lower clamp base 5 and the upper clamp base 6, and are positioned by the limiting component and the positioning component, which is convenient for installation and disassembly.

[0032] Local working principle: After the plug 14 is inserted into the interior of the slot 15, at this time, vertically insert the pin shaft 16 into the interior of the pin hole 17 to limit the end of the plug 14.

[0033] In this embodiment, a connecting wire is provided between the top end of the pin shaft 16 and the upper clamp seat 6.

[0034] Local working principle: The end of the pin shaft 16 is connected to the upper clamp seat 6 by a connecting wire to prevent the pin shaft 16 from being lost.
