摘要： A pneumatic rotary tool includes a housing, a directional changeover mechanism, and a speed regulating mechanism. The housing includes a top body and a handle. The top body is fitted with a pneumatic motor. The handle defines a forward air channel, a reverse air channel, and an air supply passage. The air supply passage is controlled by a valve being operated by a trigger so that the air supply passage communicates with the forward and reverse air channels. The direction changeover mechanism is mounted in the top body along a transverse line and passes through the forward and reverse air channels for changing the rotational direction of the pneumatic motor. The speed regulating mechanism is mounted in the handle for adjusting the flow of compressed air entering the forward air channel. The tool can be operated conveniently to change the rotational direction and the output torque of the pneumatic motor.

摘要： A nail drive method applied in an electric nail gun, in which a rotary actuator is driven to generate forward rotational kinetic energy for nailing. The rotary actuator has paired wire bundles and magnetic lines arranged in circumferential directions. The nail drive method comprises boosting a pre-loaded voltage of a battery to generate a peak voltage, and storing the electric charge generated by the peak voltage, and then releasing the peak voltage and its electric charge to the rotary actuator through a nailing signal, so that the wire bundles can generate a current to interact with the magnetic lines to generate a tangential force, so that the magnetic lines can drive the rotor to rotate for a specific angle, and the rotary actuator can directly generate a forward rotational kinetic energy for nailing. Thus, the energy conversion structure installed in the conventional electric nail gun can be omitted.

摘要： A pneumatic nail gun operated in automatic actuation mode includes a gun body, a trigger valve, and a shuttle valve. The gun body defines therein a main chamber and is provided with a forward air conduit and a return air conduit. The forward air conduit provides a path for the pressurized air in the main chamber to force a valve stem of the shuttle valve to conduct a forward movement for a drive stroke. The return air conduit provides a path for the pressurized air in the cylinder to force the valve stem to conduct a return movement after the nail gun has completed the drive stroke. By depressing an actuating bar of the trigger valve a single time, the valve stem can be forced to conduct repeated forward and return movements, and thus the nail gun can conduct repeated drive strokes for stably striking a nail.

摘要： The present invention provides a pneumatic hand tool with adjustable operating angle, comprising a grip body and a tool head body interconnected with each other. The grip body has a grip flow channel, and said tool head body has a tool head flow channel. The grip body and said tool head body are interconnected through two rotary joint faces to form a joint portion capable of adjustment of the operating angle. The two rotary joint faces respectively have connecting areas for uniform circumferential motion and high pressure air ports configured along the rotation center. And the two rotary joint faces are inclined to facilitate adjustment of the operating angle of said tool head, and to ensure good air tightness of the high pressure air ports inside the joint portion.

摘要： A nail drive device of electric nail gun includes a nailing rod and a rotary actuator that can output a specific rotation angle and can drive the nailing rod to move downward for nailing. Specifically, the rotary actuator includes a stator and a rotor surrounding it, between the stator and the rotor, even groups of electro-magnetic mutual action components are configured in pairs, to generate a tangential force to drive the rotor to rotate for a specific rotation angle, and to drive the nailing rod to move for a nailing stroke. The nailing stroke can be determined by the specific rotation angle. Thus, through the above configuration of the rotary actuator, the structure of the electric nail gun can be simplified.
