Figure 4 As shown, the opening of the blow mold segment 6 is achieved in this way.

[0032] Embodiment 2:

[0033] The difference from the first embodiment is that the front end face of the square column of the closing confirmation block 7 can also be set as a frosted surface, thereby increasing the friction between the front end face of the square column of the closing confirmation block 7 and the fixed limit block 8 and preventing the fixed limit block 8 from rotating and loosening.

[0034] Embodiment Three:

[0035] The difference from the first embodiment is that the regular hexagonal prism of the fixed limit block 8 can also be set as a regular heptagonal prism, thereby enabling the fixed limit block 8 to be rotated only by a special tool that cooperates with the regular heptagonal prism, preventing non-staff members from rotating and disassembling the fixed limit block 8.
