That is, the clamping assembly 2 is capable of clamping cables of different diameters by expanding or contracting, thereby accommodating elastic modulus measurements of cables of different thicknesses. A distance sensor 4 is provided on the slidable clamping assembly 2. It will be appreciated that the distance sensor 4 is capable of measuring the distance between the ranging plates 3 and that, due to the small range of the high accuracy distance sensor 4, it can only be provided on the clamping assembly 2 close to the ranging plates 3.
The clamping assembly 2 can clamp cables, cables with different thicknesses can be clamped by adjusting the expansion or contraction of the clamping assembly 2, and the measurement of the elastic modulus of the cables with different thicknesses by the same device is realized; during measurement, one end of the cable is fixed, the cable passes through the two clamping assemblies 2, the two clamping assemblies 2 clamp the cable, a load is applied to the other end of the cable, the cable is deformed, and the elastic modulus is obtained through calculation through the change of the numerical value recorded by the distance sensor 4.

The U-bolt 21 preferably contacts the cable more after clamping. Preferably, the U-shaped bolt 21 and the hoop seat 22 can be matched and installed on the surface of a rope body or a pipe fitting with the diameter ranging from phi 20 to phi 120 (components can be additionally processed according to actual conditions), and the novel steel wire rope has the advantages of simple structure, low production cost and wide application range.
