When assembling the clamping block 603 and the upper clamping seat 2 or the lower clamping seat 1, insert the clamping block 603 and the positioning block 605 into the assembly groove 602. Then, the second fixing bolt 601 on the outside of the upper clamping seat 2 or the lower clamping seat 1 extends into the assembly groove 602 and is connected to the screw groove 606 on the positioning block 605. In use, several clamping teeth 604 at the concave arc of the clamping block 603 can penetrate into the surface gaps of the wire rope, thereby greatly enhancing the anti-slip and anti-detachment effect, and also strengthening the stability of the wire rope connection. The clamping teeth 604 are conical, which has a good stabilizing effect.

[0025] refer to Figure 1 The upper end of the upper clamp 2 and the lower end of the lower clamp 1 are both provided with grooves 7. The end of the second fixing bolt 601 is located inside the groove 7. The inner sides of the upper clamp 2 and the lower clamp 1 are symmetrically provided with round holes 10. One end of the second fixing bolt 601 can be moved through the round hole 10. By having the end of the second fixing bolt 601 located in the groove 7, the impact of external forces can be reduced, and the stability of the second fixing bolt 601 can be improved. The round holes 10 on the upper clamp 2 and the lower clamp 1 can facilitate the insertion of one end of the second fixing bolt 601 into the screw groove 606 on the positioning block 605 of the assembly groove 602 for connection.

[0026] refer to Figure 3The inner wall of the assembly groove 602 is provided with a positioning groove 11. The positioning block 605 and the positioning groove 11 are connected by an insertion. By providing a positioning groove 11 in the inner wall of the assembly groove 602, the positioning block 605 can be easily positioned and inserted into the assembly groove 602, thereby ensuring the stability of the clamping block 603 installation.

To install the wire rope with the nut 404 thread, pass one end of the wire rope through the upper clamp 2 and the lower clamp 1, then fold the end back and pass it through again. After the nut 404 is inserted into the hexagonal groove 405 at the lower end of the second connecting plate 403 for limiting, the first fixing bolt 401 can be directly inserted from the upper end of the first connecting plate 402. The first fixing bolt 401 then passes through the second connecting plate 403 and is directly locked with the nut 404. This allows for a quick and easy connection and fixation of the upper clamp 2 and the lower clamp 1.

[0029] refer to Figure 1 Both the first connecting plate 402 and the second connecting plate 403 have through holes 5 on their inner sides. One end of the first fixing bolt 401 can pass through the through hole 5. By opening through holes 5 on the inner sides of the first connecting plate 402 and the second connecting plate 403, it is convenient for one end of the first fixing bolt 401 to pass through the through hole 5 and then connect with the nut 404.

[0031] Operating principle and advantages: During use, one end of the wire rope is passed through the upper clamp 2 and the lower clamp 1, and then the end of the wire rope is folded back and passed through again. After the nut 404 is inserted into the hexagonal groove 405 at the lower end of the second connecting plate 403 for limiting, the first fixing bolt 401 can be directly inserted from the upper end of the first connecting plate 402. The first fixing bolt 401 then passes through the second connecting plate 403 and is directly locked with the nut 404. After fixing, the several teeth 604 at the concave arc of the clamping block 603 can be inserted into the surface gaps of the wire rope, greatly enhancing the anti-slip and anti-detachment effect.

[0032] When assembling the clamping block 603 and the upper clamping seat 2 or the lower clamping seat 1, insert the clamping block 603 and the positioning block 605 into the assembly groove 602, and then extend the second fixing bolt 601 on the outside of the upper clamping seat 2 or the lower clamping seat 1 into the assembly groove 602 and connect it with the screw groove 606 on the positioning block 605.
