[0035] Step 3: Turn the handle 561 to screw the lever shaft 56 into the thread and insert it into the inner hole of the lever sleeve 12 on the preform mold;

[0036] Step 4: start the motor 51 and the reducer 52, so that the lever shaft 56 drives the preform mold 1 to rotate 180 degrees, and the mold is turned over;

[0037] Step 5: Unscrew the lever shaft 56, lift the lower mold and place it at the predetermined position, and the flipping is completed.

[0038] Embodiment 1:
