Figure 5 and Figure 8 The connecting rod mechanism in different movement states is shown.

[0090] In some embodiments of the utility model, the movement driving structure of the moving trolley 10 is also designed.

[0091] The guide rail arm 12 is installed on the rack 1 perpendicularly to the direction of the conveying rail 3, and the guide rail 1201 is arranged along the height direction of the guide rail arm 12;
