AI Technical Summary
The existing hook connection only uses a limit block for limiting the connection, which lacks safety guarantee.
The structure includes a hook body, a locking block, a connecting mechanism, a fastening assembly, and a limiting assembly. The first locking seat is connected to the second locking seat, and the bolt group is used to limit the movement in the horizontal and vertical directions. The fastening ring and the limiting plate are used to improve stability.
It achieves a stable and secure hook connection, reduces wear, and improves safety and convenience.
