[0058] Working principle of this utility model:

[0059] Compared with the traditional container transfer device, the present invention divides the original integrated structure into a split front-end moving component 10 and a rear-end moving component 20. When transferring a container, it is only necessary to first lift the container through the auxiliary equipment, and then install the front-end moving component 10 and the rear-end moving component 20 on the bottom of the container, which has the advantage of easy installation. At the same time, by pulling the dragging member 104, the movable drag rod 100 can be driven, and then the front-end moving component 10, the rear-end moving component 20 and the container can be driven to move. When turning, it is only necessary to pull the dragging member 104 to change the angle of the movable drag rod 100, which can then cause the pair of movable vertical rods 102 and the pair of movable horizontal rods 101 to deform, thereby causing the pair of movable vertical rods 102 to change their angles, so that the pair of first load-bearing sliding members 103 can simultaneously achieve steering, which has the advantages of synchronous steering and convenient steering.

[0060] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
