It is used for vacuum airflow to pass through, and the lower part of the through hole is connected to the machine linkage device to realize the upper and lower use of the fixed ejector seat, and the vacuum will also be transmitted to the upper part of the fixed ejector seat through the through hole. The inner side of the first fixing hole is plugged with a first fixing pin, and the ejector can be placed inside the placement hole for standby. Then the fixed ejector seat is aligned with the through hole and pressed down on the upper end of the base. Finally, the ejector cap is pressed and connected to the upper end of the fixed ejector seat. Some of the ejector holes are used for the penetration of the ejector, and the other unused ejector holes are used for vacuum airflow to pass through. The lower part of the through hole is connected to the machine linkage device to realize the upper and lower use of the fixed ejector seat, and the vacuum will also be transmitted to the upper part of the fixed ejector seat through the through hole.
