Abstract: A protection device of a DC-powered nail gun includes collar mounted to a connection rod on the trigger and the collar has an inner diameter larger than an outer periphery of the connection rod so that when the trigger is not pulled, the collar is positioned to pivot a second switch so that the push member of the shooting unit of the nail gun cannot activate an activation button on the second switch when a new battery pack is installed. By the collar and the pivoted second switch, the nail cannot shoot even if the push member is powered and moved by the new battery pack.

Abstract: A transmission mechanism for an electric nailing gun includes a motor, a driving wheel connected to an output shaft of the motor and having an eccentric rod, and a wear-resistant ring rotatably mounted on the eccentric rod for enabling the eccentric rod to push a slide of a nail striking mechanism of the electric nailing gun without producing much friction during rotation of the driving wheel along with the output shaft of the motor.

Abstract: A nail magazine for alternatively accommodating T-nails or U-nails includes a nail track and a stop block. The nailing track has a bottom notch and a first nail hole upwardly extended from the bottom notch for holding a T-nail. The stop block is positioned in the bottom notch of the nailing track and has a top side, a left side and a right side, which define with a peripheral wall of the bottom notch of the nailing track a second nail hole for holding a U-nail. The stop block further has a top cut groove aligned with the first nail hole such that the T-nail held in the first nail hole is in coincidence with an axis of a driving path that aligns with the second nail hole, thereby enabling the T-nail to be positively and straightly driven into a workpiece.

Abstract: A nail magazine for use in a nailing gun equipped with a firing pin having a fixed stroke includes a nailing seat having a nail slot for the passing of nails and a guide groove for guiding reciprocating motion of the firing pin of the nailing gun. A striking block is positioned in the guide groove of the nailing seat and movable along the guide groove between a standby position and a striking position where the striking block is forced by the firing pin to drive one of the nails out of the guide groove.

Abstract: The nailing gun uses a motor as a power drive to rotate a drive gear wheel and a driven gear wheel, causing the drive gear wheel and the driven gear wheel to alternatively move a slider from a nailing position to a standby position, for enabling a nail driving tip, which is fastened to the slider, to be moved with the slider from the standby position to the ailing position by spring member, which is compressed to preserve energy when the slider moved from the nailing position to the standby position.

Abstract: An electric nailing gun in which a piston head is reciprocated with a nailing plunger in a receiving chamber of a cylinder to force air out of the receiving chamber of the cylinder toward a coil of a nail driving mechanism for dissipating heat, which is generated by the coil, during down stroke of the nailing plunger, and to buffer the returning speed of the nailing plunger by compressing air, which exists between the piston head and the receiving chamber of the cylinder, during return stroke of the nailing plunger after each nailing action.

Abstract: A flashlight includes a first barrel holding a battery, a second barrel detachably coupled to the first barrel and holding a bulb, a collapsible tube connected between the first barrel and the second barrel to electrically connect the battery to the bulb and to let the second barrel to be moved away from the first barrel at a distance and turned to the desired angle and direction, and a third barrel holding a reflector and a lens and coupled to the second barrel and axially movable between a first position for enabling the light of the bulb to be projected out of the lens of the third barrel and a second position for enabling the light of the bulb to pass radially through the periphery of the second barrel.

Abstract: An electric screwdriver is disclosed to include a main body, a socket, an actuator, a switch, and a wrenching portion. The actuator is installed inside the main body, which has a front end and a rear end. The socket is rotatably positioned at the front end of the main body and is connected with the actuator. The switch is mounted on the main body. The wrenching portion is positioned at a position in proximity to the front end of the main body.

Abstract: A buffer apparatus of a nailing gun, which controls the air flow in and out a chamber of a main body of the nailing gun, reduces the vibration of the nailing gun when nailing. The air will flow in with a larger rate and will flow out with a smaller rate, such that a buffer force will be provided to a bar being punched to reduce the vibration, and more particularly, the air flow also can bring the heat out.
