  • Publication number: 20200238491
    Abstract: An electric nail gun includes a supporting frame, a swing arm, a driving unit, and a safety unit. The swing arm has a driven segment and is pivotable relative to the supporting frame between a standby position and a shooting position. The driving unit includes a driving member in contact with the driven segment of the swing arm and operable for moving the swing arm towards the shooting position. The safety unit has a stopping member that is driven by the driving member to move relative to the driven segment between a stopping position, where the stopping member blocks movement of the driven segment, and a releasing position, where the movement of the swing arm towards the shooting position is permitted.

  • Patent number: 10556331
    Abstract: An impact device for an electric nail gun having a flywheel includes a swing arm unit and an impact unit. The impact unit includes an impact member adapted to be disposed between the flywheel and the swing arm unit, and a magnetic element set mounted to the impact member, spaced apart from the swing arm unit to form a gap therebetween, and providing a magnetic force which magnetically attracts a magnetically conductive component of the swing arm unit. The swing arm unit is movable between a pre-firing position where the impact member is not in contact with the flywheel, and a firing position where the impact member is in contact with the flywheel such that rotation of the flywheel drives the impact unit to move on the swing arm unit.

  • Publication number: 20150251300
    Abstract: An electric nail gun includes a main frame, a swing arm pivoted to the main frame, an impact member mounted movably to the swing arm, and a restoring mechanism including a sliding member, a first resilient member and a second resilient member. The sliding member is mounted movably to the impact member. The first resilient member is configured such that, when the impact member is driven to move away from a rear end of the swing arm, the sliding member is drawn to move toward a rear end of the impact member by the first resilient member, and the length of the linear deformation of the first resilient member is smaller than the travel distance of the impact member. The second resilient member biases the sliding member away from the rear end of the impact member.

  • Publication number: 20150034345
    Abstract: In an electric power tool, a flywheel can be driven by a driving unit to rotate about a wheel axis to thereby impart kinetic energy to a tool body through a force transmitting portion of the flywheel. A ventilating unit is mounted to rotate with the flywheel about the wheel axis. When the flywheel is driven to rotate, cooling air is generated by rotation of the ventilating unit.

  • Patent number: 8740033
    Abstract: A nailing gun includes a swing arm having a first end pivoted to a frame, and a second end movable between a first position proximate to a flywheel to drive a hammer rod to hit a nail, and a second position distal from the flywheel. A spring plate has a spring end portion resiliently supporting the second end of the swing arm. The stop member limits the spring end portion and the second end of the swing arm from moving relative to the frame. When a safety member is subjected to an external pressure, the stop member permits the second end of the swing arm to move together with the spring end portion to the first position. The spring end portion can stably retain the second end of the swing arm at the second position in case of no external pressure.

  • Publication number: 20120074195
    Abstract: A driving unit for an electric nail gun includes a pushing block. The pushing block is movable relative to a supporting bracket of the electric nail gun along an axis, and has an inclined surface abutting against an end of a swing arm. Movement of the pushing block results in pivoting movement of the swing arm between a first position, and a second position farther away from a flywheel than the first position. The inclined surface has a slope between 0.087 and 0.7, so as to lock effectively the swing arm at the first position to thereby increase the nail-striking force of an impact member.
