[0032] Firstly, both ends of the wire rope reel assembly 6 can be placed inside the L-shaped placing round rod holes 503 on the left and right sides of the adjustable-size wire rope extension assembly 5 arranged in a row for support.

Finally, when testing a thinner wire rope, it can pass through the small wire rope anti-friction assembly 3 for buffering to avoid excessive friction during pre-tension transportation, which may affect the test. The wire rope is tied and fixed inside the wire rope tensile test assembly 2 with multiple specifications. Then, rotate the L-shaped fixing handle 209 to test the tensile force. Then, the open-hole tensile ring 202 for fixing the wire rope inside the wire rope tensile test assembly 2 with multiple specifications is used to test the small wire rope. The small wire rope is passed through the holes on the surface of the open-hole tensile ring 202 for fixing the wire rope and tied and fixed on the surface. Then, rotate the L-shaped fixing handle 209 to test the tensile force. A slightly larger wire rope is directly tied on the surface of the tensile round block 203 for fixing the wire rope and fixed by using the concave-convex round grooves 205. Then, rotate the L-shaped fixing handle 209 to test the tensile force.
