The guiding mechanism can guide the container spreader to the upper side of the container to be lifted, thereby completing the effective connection between the container spreader and the container, and can prevent the container under the container spreader from being damaged through the telescopic structure, thereby completing the guidance of the container spreader and at the same time playing a role in safety protection of the top surface of the container.

[0091] The beneficial effects of the utility model are:

[0092] The utility model provides sliding grooves on both side surfaces of the connecting frame, and the sliding pins pass through the sliding grooves to connect the side sliders to the connecting frame. The side sliders can slide up and down in the sliding grooves through the sliding pins. The springs between the connecting frame and the side sliders can keep the side sliders in the guide position, and can retract the side sliders upward when they are not aligned with the guides, so as to avoid damage to the container surface.

[0093] The utility model has a simple structure and is easy to use. The container spreader can be guided to the upper side of the container to be lifted, thereby completing the effective connection between the container spreader and the container, and preventing the container under the container spreader from being damaged, thereby playing a role in safety protection for the top surface of the container.
