[0067] When the overall volume of the goods is large and the weight is heavy, the intelligent controller 110 controls the expansion motor 601 to work, the expansion motor 601 drives the expansion bidirectional screw rod 602 to rotate, and the expansion bidirectional screw rod 602 drives the two expansion pieces 603 to move, and the two expansion pieces 603 can be close to each other or away from each other. When the two expansion pieces 603 are away from each other, a larger area of ​​support can be provided to improve the overall stability. When the two expansion pieces 603 are close to each other, the expansion pieces 603 can be retracted to reduce the space occupied by the whole. The auxiliary universal wheel 6032 facilitates the overall movement, and the cleaning bristles 6033 are used to provide a cleaning function for the outer surface of the main universal wheel 102 to prevent impurities from adhering to the main universal wheel 102 and improve the smoothness of transportation.

[0068] The intelligent controller 110 controls the operation of the electric push rod 7. When the telescopic end of the electric push rod 7 is retracted, the supporting frame 201 of the lifting unit 2 can be driven to rotate backward through the connecting sleeve 701, so that the supporting frame 201 is leaning against the supporting bevel block 108 and the expansion bevel block 6034, so that the goods are placed at an angle, shortening the overall height, which is suitable for passing through places with lower heights. Conversely, when the telescopic end of the electric push rod 7 is extended, the supporting frame 201 of the lifting unit 2 can be driven to rotate forward through the connecting sleeve 701, so that the supporting frame 201 is away from the supporting bevel block 108 and the expansion bevel block 6034, so as to facilitate the unloading of goods.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
