[0024] Please refer to Figure 1-3 A pruning machine link joint includes a link joint body 1. The link joint body 1 is a hollow structure with openings at both ends. The inside of the link joint body 1 is divided into two areas, including a first connection area 2 and a second connection area 3. The axes of the first connection area 2 and the second connection area 3 are the same, so that the two connected connecting rods can be coaxial. Six first convex ribs 4 are arranged on the inner wall of the first connection area 2, of which three first convex ribs 4 are located in the upper half of the inner wall, and the other three first convex ribs 4 are located in the lower half of the inner wall, and are symmetrically arranged, and a first slot 5 is formed between two adjacent first convex ribs 4. Eight second convex ribs 6 are arranged on the inner wall of the second connection area 3. The eight second convex ribs 6 are arranged at equal intervals, and the centers of two adjacent second convex ribs 6 are 45° apart. A second slot 7 is formed between two adjacent second convex ribs 6.

[0025] The high-strength link connector body 1 is designed by replacing the original aluminum alloy material with high-strength engineering plastics, which reduces the weight of the product while ensuring the connection strength.

[0026] An open groove 8 is provided on one side of the link joint body 1, and the open groove 8 runs through the entire link joint body 1.
