Abstract
A pneumatic nailing machine having a, driving depth controlling mechanism. The pneumatic nailing machine includes a push lever having a lower end in pressure contact with a workpiece and another end in association with a trigger. Vertical moving length of the push lever relative to a nose will change the driving depth. An eccentric body is rotatably supported on the main body. The eccentric body is positioned above the upper tip of the push lever and the upper position of the upper tip of the push lever is regulated by the eccentric body. If the eccentric body is angularly rotated to a first angular position, the push lever can be moved to its highest position for providing a minimum distance between the lower tip of the push lever and a lower tip of the nose to provide the maximum driving depth. If the eccentric body is angularly rotated to a second angular position, the distance between these tips become maximum to provide a minimum driving depth. If the eccentric body is rotated to a third angular position, the trigger is abuttable on the upper tip of the push lever for preventing pivotal movement of the trigger.
