[0027] Specifically, in the embodiment, the height adjusting mechanism 9 comprises a rotating lead screw, and the height of the height adjusting mechanism 9 is adjusted by rotating the nut of the rotating lead screw. The rotating lead screw can adopt a conventional structure in the prior art, and the present application is not limited in this regard.

[0030] In the embodiment, a plurality of support rods 5 are uniformly arranged in the circumferential direction of the preform rod 3. A plurality of height adjustment mechanisms 9 are uniformly arranged in the circumferential direction of the preform rod 3. By adopting this structure, the accuracy of height adjustment is improved.

[0031] The embodiment proposes a specific structure of the preform rod clamp 1. The preform rod clamp 1 is a first clamping block and a second clamping block connected in an openable and closable manner. One end of the first clamping block and the second clamping block is hingedly connected by a hinge.
