[0002] Wire ropes are now constantly developing in various fields. my country now uses wire rope lifting rigging for industrial construction lifting. At present, the wire ropes with locking mechanisms in society can basically meet people's needs, but there are still some problems.

[0003] Application No. 202123083136.8 discloses a wire rope with a locking mechanism. After the fixed insertion rod on the inner side of the pull rod is driven to be out of the inserted state between the limit hole under the sliding action of the third slider and the second slide rod at the upper and lower ends, the pull handle is pulled to the right under the rolling action of the ball to adjust the compression state between the limit inner rod and the locking outer frame. After the length of the wire rope body between the locking outer frame and the limit inner rod is adjusted, the pull rod is loosened so that the bottom end of the inner side of the fixed insertion rod is inserted into the inner side of the limit hole in the corresponding position under the action of the elastic potential energy of the third spring. Through the above structure, the position of the wire rope can be limited and locked relatively stably, which improves the convenience and stability of the device during use, and at the same time improves the practicality of the device during use.

[0004] The device sets a plurality of limit grooves on both sides of the limit inner rod, and then limits it with a fixed plug rod, so that the limit inner rod fixes the rope. However, there are many gaps between the limit grooves, resulting in some models of ropes not having limit grooves in suitable positions for fixing when squeezed by the limit inner rod, resulting in locking failure. Therefore, a locking mechanism for the wire rope is needed. Summary of the invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model passes the two ends of the wire rope through the second rope hole from the first rope hole, and then moves the threaded rod toward the inner side of the placement box by twisting.
