In a preferred embodiment, the size of the jaw of the movable hook is optimized according to the maximum profile parameters commonly used by shipyards.

In a preferred embodiment, the end of the movable eye plate far away from the eye hole is designed to be self-locking in use.

In a preferred embodiment, the hinge position of the movable eye plate adopts an eccentric design, so that the self-locking effect is optimized, and the self-locking can be realized by means of the gravity of the eye plate.

Compared with the prior art, the utility model discloses a technological effect and advantage:

1. the movable eye plate of the utility model can avoid the installation work of light-load hoisting eye plates and most of overhaul eye plates, reduce unnecessary elevator welding work, save manpower and material resources, and reduce the environmental pollution caused by welding and polishing work;

2. by using the movable eye plate of the utility model, the hoisting position is flexible and changeable, the movable eye plate is almost suitable for most hull structural section bars (T section bars, I-shaped steel, angle steel and the like), the installation is carried out at any time, the adaptability is strong, the waiting time of the temporary welding and cooling of the common elevator is reduced, and the working efficiency is improved;

3. when the movable eye plate is used, the self-locking can be realized by utilizing the gravity deviation during the installation, the self-locking performance is further improved after the eye plate is stressed, and the safety is high;
