20110259937 | FASTENER DRIVING TOOL - A fastener driving tool includes a flywheel rotated by a drive unit and having a wheel rim formed with teeth, an impact member having a mating toothed unit movable with a carrier frame to engage the teeth so as to be swept thereby to an end-stroke position to enable a striking rod to drive a fastener into a targeted workpiece, and an actuating unit configured to actuate the carrier frame to move from an upper position to a lower position in response to a triggering action of a trigger so as to move the mating toothed unit from an disengaging position to an engaging position. | 10-27-2011 |
20110259938 | FLOATING IMPACT APPARATUS FOR ELECTRICAL NAIL GUN - A floating impact apparatus for an electrical nail gun includes a carrier, an impact unit, and a floating unit. The impact unit includes an impact member, and at least one sliding, wheel disposed pivotally on the impact member. The floating unit includes a guiding rod together with the impact member being connected movably to the carrier, two floating members extending through the carrier to connect with the guiding rod at positions proximate to a first side of the carrier, and at least two resilient members disposed between a second side of the carrier and the floating members for biasing the guiding rod and the impact member to move relative to the carrier to thereby maintain contact between the sliding wheel and the first side of the carrier, so as to promote smooth movement and nail-striking force of the impact member. | 10-27-2011 |
20120067934 | NAILING GUN - 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. | 03-22-2012 |
20120074195 | DRIVING UNIT FOR AN ELECTRIC NAIL GUN - 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. | 03-29-2012 |
20120104069 | CONTROL MECHANISM FOR ELECTRIC NAIL GUN - The control mechanism for an electric nail gun includes: a first sensor for generating a first sensing signal in response to movement of a safety member of the electric nail gun; a second sensor for generating a second sensing signal in response to operation of a trigger member of the electric nail gun; an actuating piece adjusted selectively between a single shot position and a successive shooting position, and rotatable relative to the trigger member; a third sensor for generating a third sensing signal in response to rotation of the actuating piece; and a control unit activating a driving module of the electric nail gun upon receipt of the first or second sensing signals, and energizing an electromagnetic valve of the electric nail gun upon receipt of the third sensing signal. | 05-03-2012 |
20150034345 | ELECTRIC POWER TOOL - 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. | 02-05-2015 |
20150251300 | ELECTRIC NAIL GUN - 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. | 09-10-2015 |
20150306753 | ADJUSTING DEVICE FOR AN ELECTRIC NAIL GUN - An adjusting device for an electric nail gun includes a detecting unit, a sensing unit and an electric control unit. The detecting unit includes a detecting rod for being pushed by a nail received in the electric nail gun to be rotated. The sensing unit is for sensing the position of the detecting rod and generating a corresponding sensing signal. The electric control unit is electrically connected to a driving unit of the electric nail gun and the sensing unit, and switches the driving unit to a state corresponding to the sensing signal. | 10-29-2015 |
