When the piston rod of the rotating cylinder is displaced, the rotating cylinder drives the inclined frame 51 to rotate.

[0044] Referring to Figure 1 And Figure 3 In this process, the placement frame 2 simultaneously rotates, so that the height direction of the rotatable connection between the placement frame 2 and the linkage frame 531 changes, and then the height of one end of the linkage frame 531 changes, so that the linkage frame 531 is displaced, and the linkage frame 531 drives the placement frame 2 to slide relative to the inclined frame 51, so that the end of the placement frame 2 that is inclined downward gradually slides out of the inclined frame 51, and then can be close to the top wall or the top end of the inclined surface of the external object, facilitating the removal of the goods.

[0051] The implementation principle of the AGV trolley convenient for interacting goods provided by the embodiment of the application is as follows: when two trolley bodies 1 need to interact, so that the transported goods are transferred, the two AGV trolleys are close to each other and docked. After the docking is completed, the lifting mechanism 4 adjusts the height of the placing rack 2, so that the placing racks 2 on the two AGV trolleys are at the same height. Then, the driving assembly 31 on the two AGV trolleys drives the corresponding interaction roller 32 to rotate, so that the interaction roller 32 on the AGV trolley carrying the goods gradually transports the goods to the other AGV trolley. In this process, the interaction roller 32 on the other AGV trolley moves the gradually close goods to the predetermined placing position on the self, so that the interaction between the AGV trolleys is realized, thereby effectively increasing the transportation efficiency of the goods without the need of manpower or setting an additional mechanism.
