[0043] When the workbench 3 rotates, the lifting rod 52 revolves around the revolution center of the workbench 3. Before the lifting rod 52 falls into the gap 71, the lifting rod 52 first moves to the guide surface 72, which is inclined downward relative to the current state of the lifting rod 52, therefore, with the rotation of the workbench 3, the lifting rod 52 gradually moves downward under the influence of gravity, and the two clamp blocks 4 gradually approach the cosmetic box 12 under the pulling of the connecting rod 51 until they are attached to the outer wall of the cosmetic box 12, after the lifting rod 52 falls into the gap 71, the lifting rod 52 is completely separated from the driving block 7, and the gravity of the counterweight 53 is applied to the clamp block 4, so as to clamp the cosmetic box 12.
[0044] When the clamping of the cosmetic box 12 is released:
[0045] With the re-rotation of the workbench 3, the lifting rod 52 moves to another guide surface 72 and contacts with it; the guide surface 72 is inclined upward relative to the current state of the lifting rod 52, therefore, with the rotation of the workbench 3, the lifting rod 52 gradually moves upward under the pushing of the guide surface 72, and the two clamp blocks 4 are pushed apart by the connecting rod 51, so as to release the clamping of the cosmetic box 12.
