[0028] Please refer to Figures 1 to 6 , an arc-shaped adjustment moving chute 10 that gradually approaches the center of the adjustment outer gear ring 6 is penetrated through the adjustment outer gear ring 6. Then, when the adjustment outer gear ring 6 rotates, its driving adjustment frame 9 can move relatively in the adjustment moving chute 10, and then drive the driving adjustment frame 9 to move, thereby driving the vertex adjustment seat 8 to be adjusted. The driving adjustment frame 9 is movably connected in the adjustment moving chute 10.

[0029] Please refer to Figures 1 to 6 , a transmission gear 4 is connected to the lower mold 1 through a shaft pin to form a hinge structure with the shaft pin as the rotation axis, so that the transmission gear 4 can rotate at a fixed position on the lower mold 1, and the transmission gear 4 meshes with the outer side of the adjustment outer gear ring 6.
