[0002] A cable clamp is a commonly used wire-holding tool in the construction and maintenance of overhead lines for power, telecommunications, and railway electrification. The existing cable clamp consists of an upper clamp, a lower clamp, a pressure plate, and a pull plate. The cable is placed between the upper and lower clamps, and the pull plate slides on the lower clamp, thereby driving the lower clamp downward through the pressure plate to clamp the cable.

[0003] Among them, the models of cables and wires that can be clamped by existing wire clamps are all within a certain range of values. When electricians clamp cables with larger diameters, they need to use wire clamps of corresponding models. When clamping thinner cables through wire clamps, the wire clamps also need to be changed in model. Therefore, electricians need to bring different models of wire clamps according to the diameter of the cables during operation, which is more troublesome and has certain limitations in use.
