Abstract: A striking device includes a swing arm unit, an impact member and two restoring units. Each of the restoring units includes a stationary seat removably connected to the swing arm unit, a moving seat removably and co-movably connected to the impact member, first and second coupling sets, and a resilient member interconnecting the stationary seat and the moving seat to bias the moving seat toward the stationary seat. For each of the restoring units, two portions of the first coupling set are formed respectively on the stationary seat and the swing arm unit and coupled removably with each other, and two portions of the second coupling set are formed respectively on the moving seat and the impact member and coupled removably with each other.

Abstract: An impact device is adapted to be mounted to an electric nail gun that includes a flywheel, and includes a swing arm unit, a track unit and an impact unit. The swing arm unit is adapted to be pivoted toward or away from the flywheel. The track unit includes a guiding track movably connected to the swing arm unit. The impact unit is connected to the guiding track, and is movable relative to the guiding track in a striking direction and a return direction that are opposite to each other. The guiding track is movable resiliently relative to the swing arm unit between a front position, where the impact unit is adapted to contact the flywheel, and a rear position, where the impact unit is adapted to be spaced apart from the flywheel.

Abstract: A safety member is adapted for use in a muzzle of a nail gun. The muzzle defines a nail passage that is for passage of a nail, and a gap that spatially communicates with the nail passage. The safety member is slidable in a nail striking direction of the nail, and includes a slider adapted to be disposed in the gap, and having a flat surface, a platform and an abutment end. The flat surface is adapted to face the plate member. The platform protrudes from the flat surface toward the plate member and cooperates with the plate member to define a nail ejection opening therebetween. The abutment end extends from the platform and extends beyond the nail ejection opening for contact with an object to be fastened.

Abstract: A nail gun includes a muzzle device, a cartridge device and a driving device. The muzzle device includes a safety member having an abutment end retractable when pushed. The cartridge device includes a stop member for blocking the drive stroke when a number of the nails is less than a predetermined number. The driving device includes a linking member co-movable with the safety member, and a trigger unit including a pivotable trigger, an inner arm co-movable with the trigger, and a switch member. When the switch member is at a sequential striking position and when the trigger is pivoted before a rearward movement of the linking member, the inner arm is withdrawn from a route of the rearward movement to avoid actuation of the drive stroke.

Abstract: A status indicating device for a power nail gun includes a trigger adapted to be disposed on a gun body and having at least one transparent portion, and a light emitting module adapted to be disposed between the gun body and the trigger for emitting light through the transparent portion.

Abstract: A dual safety combustion powered tool device includes a push member disposed to be pressed against a targeted surface to bring a lever to turn to be closer to an actuating unit. A trigger body is pulled to move the actuating unit so as to permit an actuating region to abut against the lever and to turn the actuating unit to an orientation where an actuating region is engageable with an ignition switch. Subsequently, a further movement of the trigger body to a final-stage position permits the actuating region to switch on the ignition switch so as to ignite combustion for initiation of a stroke movement of a driver blade. With such construction, undesired firing of the combustion powered tool device can be avoided.

Abstract: A fan motor is adapted to be mounted in a combustion-powered tool. The combustion-powered tool has a housing. The fan motor includes a fan unit, a motor for driving the fan unit, a vibration-absorbing unit, and a clamping unit. The vibration-absorbing unit includes a rigid support that is adapted to be mounted fixedly in the housing of the combustion-powered tool, and an elastic member sleeved over the motor and molded on the rigid support such that the rigid support is disposed around the elastic member. The elastic member is disposed between the rigid support and the motor for absorbing vibrations generated by the motor. The clamping unit includes at least one clamping member sleeved over the elastic member for clamping and retaining the elastic member on the motor.

Abstract: The present invention is to provide a nailing depth adjusting and positioning device for a power nailer in order to protect the distal thread and stabilize the operation. The device having a circular groove formed in a rotatable member and a retainer ring located in a link in order to prevent the rotatable member from being overly rotated (to protect the distal thread), and the disengagement of the device, and having a steel ball and a spring mounted in the rotatable member, the steel ball cooperates with the several gaps in the safety device to locate the rotatable member, such that the starting distance of the device may stably be adjusted. Thereby, the depth of nailing and the position may be successively maintained.
