Abstract
A safety mechanism for a nailing machine in which a start valve for a hammering mechanism is driven by cooperative action of operating a trigger lever and moving a contact arm to an uppermost point where it is pressed against a material to be nailed. The hammering mechanism for hammering a nail is supplied to a nose section arranged at a front end portion of a housing and is actuated by the start valve. The safety mechanism comprises: an arm body provided with the contact arm and being vertically movable along the nose section; a threaded member attached at an upper end portion of the arm body, the threaded member being rotatably and vertically movable; a push-up member positioned above the threaded member, the push-up member engaging with the threaded member to push up the trigger lever to make effective the operation of the trigger lever when the contact arm is moved to the uppermost point thereof; an adjust dial attached to the housing and positioned below the trigger lever, for rotating the threaded member; and a cover member covering the contact arm in part which is below the adjust dial and above the lower end of the arm body. The adjust dial may operate independently of the contact arm. The threaded member may have a hole for slidably receiving the receiving member.
