    摘要： A nail gun with a hidden nail head structure includes a gun body, a nail magazine, and a nail head located at the nail exit of the nail magazine. The nail magazine is a component for supplying nails, and the gun body is a component for striking nails. The gun body has a connecting part extending towards the nail exit. The nail head is fixedly connected to the nail magazine on both sides by fasteners, and the upper part of the nail head is fixed to the connecting part by fasteners, realizing the hidden installation of the nail head. By adopting an insertion-type installation method, the nail head is hidden, making the overall appearance of the nail gun more elegant and attractive, with convenient assembly and connection, a more stable structure, simplified nail head structure, more convenient processing of components, and reduced manufacturing costs.

    摘要： An pressure regulating valve assembly for a pneumatic spray gun is disclosed. The pressure regulating vale component is configured inside the pressure regulating passage of the gun body, comprising a pressure regulating screw seat, a pressure regulating rod going through the pressure regulating screw seat and in threaded connection with the pressure regulating screw seat. A pressure regulating seal ring is configured between the pressure regulating rod and the pressure regulating screw seat. A clamping check ring is configured in the middle portion of the pressure regulating rod. The clamping check ring is used to limit the position of the pressure regulating rod. The inner end of the pressure regulating rod is provided with a pressure regulating valve. The position of the pressure regulating valve is limited by the split damping ring configured on the end portion of the pressure regulating rod.
