[0002] Universal joint shaft utilizes the characteristics of its mechanism, so that the two shafts can be continuously rotated and reliably transmit torque and motion even if the shafts are not on the same axis and there is an included angle between the shafts. The biggest feature of the universal joint shaft is that it has a large angular compensation capability, is compact in structure, and has high transmission efficiency. The included angle between the two shafts of different structural types of universal joint shafts is not the same, generally between 5° and 45°. However, the traditional universal joint shaft is not convenient to assemble, and it is not convenient to replace the parts. During transmission, it cannot effectively limit a certain direction, and it is difficult to realize rotation or swing between each other.

[0003] To solve the above problems, the patent document No. CN217081167U discloses a universal joint shaft, comprising a first shaft fork and a second shaft fork, the first shaft fork and the second shaft fork are connected by a cross shaft and a retainer. By setting the retainer, the problem of being unable to insert due to shaft installation can be well solved, and the stability of the connecting shaft is improved. By setting the telescopic device, and the pull ring as a movable node, it can swing up and down and be limited in direction, so as to complete the complicated action and realize the continuous rotation of the two shafts connected.
