A nailing gun trigger safety device according to the invention comprises a contact-jacking mechanism, a poking mechanism linked with the contact-jacking mechanism and a transmission mechanism linked with the poking mechanism, the contact-jacking mechanism can be slidably mounted on a nozzle of the nailing gun body; and the device is characterized in that: the nailing gun trigger safety device is arranged on the nailing gun body and is linked with a trigger mechanism; the trigger mechanism comprises a trigger and a pressing sheet driven by the trigger, and an air needle for starting up a nailing gun percussion mechanism, the contact-jacking mechanism is linked with the pressing sheet via the poking mechanism and the transmission mechanism; when the contact-jacking mechanism is not pressed, the pressing sheet is positioned at a first initial position and the air needle is beyond the stroke of the pressing sheet; when the contact-jacking mechanism is pressed, the contact-jacking mechanism pushes the pressing sheet to a second initial position via the poking mechanism and the transmission mechanism, and the air needle is within the stroke of the pressing sheet. The invention has the advantage such as lower manufacturing cost, smaller volume, lighter weight and better safety.
L'invention concerne un dispositif de sécurité du déclencheur d'une cloueuse et une cloueuse munie de celui-ci. Ledit dispositif est situé sur le corps de la cloueuse (1) et s'interconnecte avec un mécanisme du déclencheur (50). Ledit dispositif comprend un mécanisme de bec (20) et un mécanisme d'actionnement (30) interconnecté avec le mécanisme de bec (20). Ledit mécanisme de bec (20) est monté de manière coulissante sur l'extrémité distale (11) du corps de la cloueuse (1). Ledit mécanisme d'actionnement (30) s'interconnecte avec le mécanisme de bec (20). Ledit dispositif de sécurité du déclencheur d'une cloueuse comprend en outre un mécanisme de transmission (40) interconnecté avec le mécanisme du déclencheur (50) et ledit mécanisme de transmission (40) s'interconnecte respectivement avec ledit mécanisme d'actionnement (30) et le mécanisme du déclencheur (50). Une telle structure mécanique rend la structure du dispositif de sécurité du déclencheur d'une cloueuse simple et réduit son coût de fabrication.
