The lifting and rotating mechanism has a lifting seat, a rotating plate, and two bottleneck seats. Each of the two bottleneck seats has at least one bottleneck mold, with the rotation of the rotating plate, positions of the two bottleneck seats are selectively interchanged between a first and the second operating positions. The injecting mechanism has a female mold and a core mold installed at the first operating position. The conveying mechanism has a conveying seat connecting the two bottleneck seats whose bottleneck mold clamps a preform is installed at the second operating position. The conveying seat is driven by a convey driving device.
