A drive motor is fixed to the top center of the fixed column, and a rotating rod is fixed to the drive end of the drive motor. A rotating disk is rotatably connected to the other end of the rotating rod. A connecting pipe is fixed to the front end of the rotating disk. Fixed blocks are fixed to both ends of the connecting pipe. A slot is provided in the middle of the fixed block. An mounting groove is provided in the middle of the mounting block. Movable grooves are provided at both ends of the mounting block. A spring is provided inside the movable groove. The spring is slidably connected to a limiting block. A tension column is slidably connected inside the movable groove.

[0004] Regarding the aforementioned technologies, the inventors have discovered at least the following problems: the adjustable angle of the loading arm is relatively limited, resulting in poor angle adjustment, low flexibility, and difficulty in aligning with the can opening.
