[0002] A cable tensioner is a tool or device used to fix or tighten ropes, wires and other materials. It is usually made of metal or plastic and has an adjustable function. The tightness can be adjusted as needed. Cable tensioners are widely used in outdoor sports, construction, ship maintenance and other fields. They can improve work efficiency and ensure safety.

[0003] After searching, a Chinese patent discloses a power transmission and transformation line tensioner, and its authorization announcement number is (CN217115390U), which includes a winding plate, two of which are provided, a bobbin is provided between the two winding plates, a steel wire rope is wound around the outer wall of the bobbin, both ends of the two winding plates are fixedly connected with a first fixing pin, one end of one of the fixing pins is provided with a hanging assembly, and the outer wall of the other fixing pin is rotatably connected with an adjustment mechanism, and a ratchet is provided on one side of one of the winding plates.

[0004] This patent sets an adjustment block so that the adjustment block can rotate on the fixed pin of the winding plate, and when rotating, it drives the support rod to rotate around the axis of the fixed pin.
