動吸収機構。[Claims for Utility Model Registration] A housing having a grip portion and having a cylindrical injection portion for ejecting a stopper at the lower part thereof, and a housing that is housed in the housing so as to be able to reciprocate in the vertical direction, and a lower portion of the housing. a movable cylinder biased by a spring; a striking piston that is housed in the movable cylinder so as to be able to reciprocate in the vertical direction and that is integrally formed with a striking driver that is slidable within the injection section; an automatic switching valve mechanism that selectively connects the interior of the movable cylinder to a supply source of driving compressed air and the atmosphere as the movable cylinder reciprocates; A repetitive action nailing machine comprising a contact member provided in the housing and a trigger valve that operates the automatic switching valve by operating a contact lever provided so as to be manually operable, wherein a part of the contact member is inserted into the housing. The contact member is inserted so as to face the lower end surface of the movable cylinder, and the lower end of the contact member is pressed against the surface of the material to be driven, thereby movable the entry portion that has moved upward relative to the housing. The contact member is brought into contact with the lower end surface of the cylinder and separated from the housing until it reaches the top dead center, and inside the housing, compressed air moves the movable cylinder to the top dead center position of the contact member with its lower end entering the housing. control to hold the movable cylinder in the raised position before startup and release the holding after startup by providing an air pressure operating mechanism to raise the movable cylinder to A recoil absorption mechanism in a repeating action nailing machine characterized by being provided with a valve.
