A driving device for resetting a hitting nail bar of the pneumatic nail gun, which is mounted in a gun body including a main air chamber, a trigger valve, a hitting nail bar and a bottom cylinder chamber disposed therein is provided. The driving device includes a main gas channel and a sensing valve component slidably disposed in the main gas channel. The main gas channel communicates with the main air chamber and the bottom cylinder chamber via the trigger valve. The sensing valve component is controlled by the position of the hitting nail bar to be either opened or closed. The sensing valve component is opened on the condition that a reset state of the hitting nail bar is excluded, and the high-pressure air is introduced from the main air chamber into the bottom cylinder chamber to drive the hitting nail bar to move upwardly to reset rapidly.

Driving device for resetting hitting nail bar of pneumatic nail gun

An actuator is arranged in a housing of an electrical nail gun. The actuator includes a sliding base, an external-running brushless direct current motor, a swing base and an electric driver. The sliding base is slidably disposed on an end of a located supporter which is positioned in the housing. The sliding base loads a spring and forms a hitting nail bar thereon. The motor has a stator and a rotator attached on an outer wall of the stator. A flywheel is driven by the motor and is configured to engage or disengage with/from the sliding base. The swing base is pivotally mounted on the housing. The swing base is adjacent to the sliding base and the supporter. The motor is installed in the swing base. The electric driver is attached to the housing and is adjacent to an end side of the swing base. The electric driver has a rod member driven by electricity. The rod member drives the swing base to swing to a first position where the flywheel meshes with the sliding base to thereby drive the sliding base to move downwards, and a second position where the flywheel disengages from the sliding base to thereby cause the sliding base to reposit. It is advantage to simplify the configuration of the actuator for the flywheel and is useful for the miniaturization of the electrical nail gun.

Actuator for electrical nail gun

A clutch mechanism arranged in a housing of an electrical nail gun includes a sliding base, a driver driven by electricity, a swing base pivotally mounted on the housing, and an electric driver attached to the housing and being adjacent to an end side of the swing base. The sliding base is slidably disposed on an end of a free roller positioned in the housing, and the sliding base loads a spring and forms a hitting nail bar thereon. The driver has a motor and a flywheel driven by the motor, and the flywheel is configured to engage or disengage with/from the sliding base. The swing base is adjacent to the sliding base and the free roller and receives the driver therein. The electric driver has a rod member driven by electricity, and the rod member drives the swing base to swing to a first position where the flywheel meshes with the sliding base to thereby drive the sliding base to move downwards, and a second position where the flywheel disengages from the sliding base to thereby cause the sliding base to reposit. Thus, it is an advantage to improve service life and stability of the electrical nail gun.
