The nail is a nail that uses the gunpowder gas generated by the empty bomb as the power to drive into the building, and the role of the nail is to drive the nail into the substrate such as concrete or steel plate to play the role of fastening the connection.
In order to alleviate the noise phenomenon when the nail is fired, it is usually composed of a nail and a gear ring or a plastic positioning ring, although it can slow down the noise of the nail shooting to a certain extent, but the sound attenuation effect is limited, and the plastic positioning ring is also easily damaged.
Therefore, it is necessary to provide a nail with a silencing function to solve the above technical problems.
