の安全機構。[Claims for Utility Model Registration] (1) It has an arm that moves parallel to the nose when the tip of the nose is pressed against an object and acts on a trigger lever that is pivotally supported on the handle. an intermediate lever pivotally supported on the arm, the distal end of the intermediate lever extending into the path of movement of the distal end of the arm and capable of abutting the arm; When you press the tip of the nose against the object and pull the trigger lever, the intermediate lever pushes the valve pin of the trigger valve, the trigger valve acts on the main valve, and the blade drives into the nose. In the safety mechanism of a nail gun configured to drive a nail placed in a chamber into an object, but not to drive the nail unless the tip of the nose is pressed against the object, the length of the intermediate lever is:
When the tip of the nose is pressed against the object without pulling the trigger lever, the tip of the arm hits the tip of the intermediate lever and pushes the tip, but when the trigger lever is pulled, the tip of the nose is pressed against the object. The intermediate lever has a length that does not reach the movement path of the arm tip even when pressed against the object, and a notch is formed at the tip of the intermediate lever to receive the arm tip, so that the nose tip is pressed against the object. When the trigger lever is pulled with the tip of the arm pressed, the tip of the arm locks in the notch, locking the intermediate lever in its locked state, and this lock prevents the trigger lever from being released even if the trigger lever is released. A safety mechanism for a nail gun characterized in that the trigger lever does not return to a non-operating position. (2) Even after pulling the trigger lever and pressing the tip of the nose against the object to drive the nail into the object, the intermediate lever will not close to the valve pin unless the trigger lever is returned to the release position, even if the nose is removed from the object. A safety mechanism for a nail gun according to claim 1, characterized in that the blade does not return to its original position when the blade is not returned.
