Next, when the lever 15 is pushed back, the swing arm 12 is pushed down, and the state in which the touch sensor 8 is fixed to the blow pin grip portion 10 is released. Next, the touch sensor 8 is set to 90
゜ Turn to disengage the engagement head 8b from the engagement hole 16, and remove the touch sensor 8 from the coordinate axis table 7. Next, as described above, the blow pin 9 is fixed to the blow pin grip 10 instead of the touch sensor 8 and attached to the coordinate axis table 7. At this time, since the blow pin grip 10 is located at the center of the die, the blow pin 9 fixed to the blow pin grip 10 is also at the center. Therefore, when the blow pin 9 is driven into the parison held by the base 2 of the mold 1, the blow pin 9 is located at the center of the parison. There's no going out.
