摘要： An exhaust mechanism of a pneumatic nailing in which a striking cylinder is accommodated in a body and a striking piston in the striking cylinder is driven to drive a nail when compressed air is supplied to and exhausted from an upper portion of the striking cylinder, comprises: an inner cap arranged in the upper portion of the striking cylinder; a cylinder cap covering the inner cap; an exhaust chamber formed along inside the body between the inner cap and the cylinder cap; and a throttle hole formed in a lower portion of the exhaust chamber, wherein the exhaust air exhausted from the upper portion of the striking cylinder is discharged from the throttle hole via the exhaust chamber.

摘要： Projected portions 17, 18, 19 are formed at three positions in the middle and on left and right ends of the front surface of a driver 13 of a staple hammer. The width of the projected portion 18 in the middle is smaller than the distance between both leg portions S.sub.3, S.sub.4 of a staple S, and the projected portion 18 is not in contact with the upper surfaces of bends S.sub.1, S.sub.2 of the staple S. Further, the distance between the projected portions 17, 19 on both left and right ends is slightly smaller than the total width of the staple S. The projected portions 17, 19 are located above the bends with radii, and are not in contact with the bends. At the time of hammering, the projected portion 18 in the middle impinges the middle portion of the top surface of the staple S, allowing both leg portions S.sub.3, S.sub.4 of the staple S to ground upon the object to be hammered so as to be expanded. At the time of penetration of the leg portions, the leg portions completely penetrate into the object to be hammered with the projected portions 17, 19 on both left and right ends contacting the bends.

摘要： The operation mode of a nailing machine can be automatically and reliably switched, for its selection, from the successive nailing mode and the one-shot nailing mode and vice versa by changing the order of operating a trigger lever and a contact arm. In the selected mode, the nailing work can be performed. By releasing both the trigger lever and the contact arm, the machine is returned to its initial mode. When the contact arm is moved to the top dead center after the trigger lever is operated, a portion of a slide die comes in contact with the underside of the trigger lever. When the trigger lever is operated after the contact arm is moved to the top dead center, the portion of the slide die comes in contact with the upper side of the trigger lever, thereby preventing a further movement of the contact arm to the bottom dead center.
摘要翻译： 打钉机的操作模式可以通过改变操作触发杆和接触臂的顺序，从连续打钉模式和单次打钉模式自动可靠地切换，反之亦然。 在所选择的模式中，可以执行打钉工作。 通过释放触发杆和接触臂，机器返回初始模式。 当触发杆操作之后接触臂移动到上止点时，滑动模具的一部分与触发杆的下侧接触。 当接触臂移动到上止点之后操作触发杆时，滑模的部分与触发杆的上侧接触，从而防止接触臂进一步向下死点移动 。
