Abstract: An electric nail gun includes a main body unit, a hammer unit, and a motor unit. The hammer unit includes a hammer member that is adapted for striking a nail, and a resilient member that has two opposite ends respectively abutting against the hammer member and the main body unit. The resilient member of the hammer unit constantly provides a hammer restoring force for the hammer member to move in a striking direction for striking the nail. The motor unit is mounted to the main body unit, and includes a lifting wheel. The lifting wheel has at least one pushing portion that separably engages the hammer member, and that is operable to push the hammer member to move in an energy storage direction opposite to the striking direction such that the resilient member of the hammer unit is compressed and provides the hammer restoring force to the hammer member.

Abstract: Disclosed are a nailing device and an adjustable nailing depth module used in a gun body of the nailing device. The gun body has a muzzle and a safety device capable of moving reciprocally with respect to the muzzle. The adjustable nailing depth module includes a fixed rod and an adjusting shaft. The fixed rod and muzzle are parallelly fixed to the gun body and extended to a length. The fixed rod has an end section away from the gun body. The adjusting shaft and the end section of the fixed rod are coupled to each other by a screw structure. The adjusting shaft is corresponsive to the safety device. The adjusting shaft can move away from or close to the safety device by the screw structure. The safety device is blocked by the adjusting shaft to restrict the distance of pressing the safety device downwardly towards the muzzle.

Abstract: A nail gun includes a body, a valve unit, a nail striking member and a detector. The body has a nail path, an air chamber, and an intake chamber guiding flow of air into the air chamber. The nail striking member is drivable by air pressure in the air chamber for striking a nail in the nail path. The valve unit is operable to switch between unblocking and blocking states to respectively permit and prevent fluid communication between the intake chamber and the air chamber. The detector is connected pivotally to the body, and is contactable with the valve unit such that, when there is no nail in the nail path, the valve unit is controlled by the detector to be in the blocking state.

Abstract: A nail gun includes a gun body, a safety unit, a detecting member and a blocking unit. The gunbody defines a firing path and a guiding groove therein. The safety unit is movable relative to the gun body. The detecting member and the blocking unit are disposed on the firing seat. When both the firing path and the guiding groove receive nail therein, the detecting member abuts against the nail in the guiding groove and is spaced apart from the nail in the firing path, and the blocking unit permits the movement of the safety member relative to the gun body. When the firing path and the guiding groove are empty, the detecting member is inserted into the firing path, and the blocking unit hinders the movement of the safety member relative to the gun body.

Abstract: A gas container driving device for use in a gas nail gun includes a main body and a cap member. The main body is connected to a gun body of the gas nail gun and has a lever section. When a sleeve is moved relative to the gun body for sealing a combustion chamber, the lever section is pushed and moved by the sleeve to push a gas container received in a receiving space of the gun body for releasing gas into the combustion chamber. The cap member is pivoted to the main body and engages removably the gun body for sealing the receiving space during operation of the main body.
