step 1: when the steel wire rope is installed, firstly, the steel wire rope (5) below the bending part is arranged in the clamping groove (13) on one side, the positive drawing tooth (30) and the negative drawing tooth (31) are arranged on two sides of the steel wire rope strand (29) and are attached to the surface of the steel wire rope strand (29), the steel wire rope fixing ring (9) is rotated along a rotating shaft between the steel wire rope fixing ring (9) and the clamping area (7), the limiting buckle (16) is pressed into the limiting buckle groove (19), when the limiting buckle (16) is pressed, the upper end of the limiting buckle groove (19) compresses the distance between the trapezoidal limiting blocks (17), when the trapezoidal limiting blocks (17) completely pass through the upper end of the limiting buckle groove (19), the resetting of the trapezoidal limiting blocks (17) is realized due to the release of the elasticity, so that the upper end of the limiting buckle groove (19) realizes the limiting of the trapezoidal limiting blocks (17), thereby realizing the limit of the steel wire rope fixing ring (9);
step 2: limiting rubber blocks (15) are symmetrically arranged on the inner walls of the clamping groove (13) and the steel wire rope fixing ring (9) and can flexibly press the steel wire rope (5), the steel wire rope fixing ring (9) above the first steel wire rope area (10) and the second steel wire rope area (12) is fixed in sequence, and the first steel wire rope area (10) below and the second steel wire rope area (12) are wound and are arranged in the winding groove (14);
and step 3: a first steel wire rope area (10) and a second steel wire rope area (12) below the winding groove (14) are placed in the clamping groove (13) on the other side and are fixed through a steel wire rope fixing ring (9);
and 4, step 4: the upper clamping cover (1) is covered above the lower clamping cover (2), the locking edges (8) are combined, the limiting strips (24) at the two ends of the X-shaped limiting block (4) are respectively arranged in the limiting strip grooves (26) of the upper clamping cover (1) and the lower clamping cover (2) and the limiting strip grooves (26) of the locking clamping block (3), the locking clamping block (3) is pushed towards the centers of the upper clamping cover (1) and the lower clamping cover (2), the limiting strips (24) are pushed towards the two sides due to the pushing of the V-shaped block (28), and the angle of the limiting strips (24) is changed, so that the position of the locking clamping block (3) is locked, and the clamping of the steel wire rope (5) is realized;
and 5: when the steel wire rope winding device is used, when a first steel wire rope area (10) of a steel wire rope (5) is pulled towards the direction far away from a steel wire rope winding area (11), the reverse drawing teeth (31) on the inner wall of the clamping groove (13) limit steel wire rope strands (29) of the steel wire rope (5), meanwhile, the first steel wire rope area (10) and the second steel wire rope area (12) are mutually wound, so that the second steel wire rope area (12) limits the first steel wire rope area (10), and when the steel wire rope (5) is pulled towards the direction far away from the steel wire rope winding area (11), the forward drawing teeth (30) on the inner wall of the clamping groove (13) limit the steel wire rope strands (29) of the steel wire rope (5).
