As the nail core body 12 moves, the nail head body 5 will enter the nail column 1 through the through hole 3, and the nail head body 5 will move downward all the time. While moving downward, the nail head body 5 will contact the rubber pad 205, and the rubber pad 205 will squeeze the spring 203 and the telescopic rod 204 downward, and the spring 203 and the telescopic rod 204 will be deformed, so that the spring 203 and the telescopic rod 204 buffer the impact force of the nail head body 5 moving downward, and prevent the brim body 8 from being deformed due to excessive impact force, and then the staff will use a nail gun to pull the nail core body 12 out of the brim body 8.

Then the staff presses the trigger on the nail gun, and the nail gun pulls the nail core body 12 inward. When the nail core body 12 moves, it will drive the extrusion head 11 to squeeze the lower half of the protrusion package 7. At the same time, when the extrusion head 11 moves, it will drive the nail core head 10. The nail core head 10 drives the extrusion head 1 4 through the connecting rod 6 to squeeze the upper half of the protrusion package 7, so that the diameter of the protrusion package 7 becomes larger, so that the protrusion package 7 is clamped between the two fixings. In the connecting hole, as the nail core body 12 moves, the nail head body 5 will enter the nail column 1 through the through hole 13, and the nail head body 5 will move downward all the time. While moving downward, the nail head body 5 will contact the rubber pad 205, and the rubber pad 205 will squeeze the spring 203 and the telescopic rod 204 downward, and the spring 203 and the telescopic rod 204 will be deformed, so that the spring 203 and the telescopic rod 204 buffer the impact force of the nail head body 5 moving downward, and prevent the brim body 8 from being deformed due to excessive impact force. Then the staff will use a nail gun to pull the nail core body 12 out of the brim body 8.
