Abstract
The present invention provides a structure of the inner head housing, which is placed inside the nail tip cover. The structure includes a movable base of the air-resistant ring, which is placed inside the slot of the fixed liner ring. The resilient component is used to support the movable base towards the direction of the cylinder under normal circumstances. The fixed liner ring is a single component; therefore, it is easy to process and make it smooth. The inner side of the nail tip cover does not need to be processed; therefore, it greatly reduces cost of processing and becomes more practical.
