[0033] Specifically, the first movable piece 1 and the second movable piece 2 are both hinged to form a scissor structure. The limiting part 3 is located on one side of the scissor structure, and the limiting part 3 is partially connected to the first movable piece 1 and partially connected to the second movable piece 2. The first movable piece 1 and the second movable piece 2 are clamped to different parts of the steel wire rope 6 through the limiting part 3 to realize clamping and limiting of the steel wire rope 6, so that different parts of the steel wire rope 6 deform towards each other, and the tension degree of the steel wire rope 6 is detected. The elastic part 4 is arranged on the other side of the scissor structure, and is used to drive the first movable piece 1 and the second movable piece 2 to clamp the steel wire rope 6 through the limiting part 3.
