[0033] Working principle: First, when the size of the notch of the adjusting disk 201 needs to be adjusted, the adjusting bolt 210 is manually rotated, and the adjusting bolt 210 is threadedly connected to the annular plate 202, and the annular plate 202 is slidably connected to the mounting column of the adjusting disk 201. Therefore, the rotation of the adjusting bolt 210 will drive the annular plate 202 to move downward under the influence of the thread. Since the annular plate 202 is rotatably connected to the first connecting rod 203, and the first connecting rod 203 is rotatably connected to the push plate 204, and the push plate 204 is in contact with the limiting plate 209, the downward movement of the annular plate 202 will drive the push plate 204 to move toward the notch side of the adjusting disk 201.

By adjusting the distance between the two groups of adjusting plates 206, the size of the notch of the adjusting disk 201 can be adjusted, which is convenient for the staff to use the rotating structure 2 to transport bottles of different sizes;

[0035] Finally, when the rotating structure 2 needs to be maintained, the protrusion above the fixing block 403 is manually pulled, and the fixing block 403 moves to separate from the cover plate 3, and then the cover plate 3 is pulled to complete the maintenance. When the maintenance of the rotating structure 2 is completed and the cover plate 3 needs to be installed, the fixing block 403 is pulled again, and the movement of the fixing block 403 causes the spring 402 to deform, and then the docking rod 405 at the bottom of the cover plate 3 is aligned with the docking sleeve 406 of the adjusting disk 201 and pressed downward. When the cover plate 3 is in contact with the adjusting disk 201, the fixing block 403 is released, and the spring 402 will restore the deformation and push the fixing block 403 to move and fit above the cover plate 3, thereby completing the fixation of the cover plate 3. The operation is simple, and it is convenient for the staff to perform regular maintenance on the rotating structure 2.
