  • Patent number: 10144120
    Abstract: A fastener driving tool with an improved nose chamber guide member is provided for driving fasteners of at least two different lengths. Multiple fasteners in a magazine are guided toward a driving bore to be driven by a driver blade. A nosepiece defines a passageway of the fasteners. The guide member is operatively connected to the nosepiece and is configured for transitioning between a first position and a second position relative to the nosepiece in a direction transverse to an operational flow direction of the fasteners. In the first position, the guide member is disposed to align with the driving bore for allowing driving of the fasteners having a first length. In the second position, the guide member is disposed out of alignment with respect to the driving bore for allowing driving of the fasteners having a second length, which is longer than the first length.

  • Patent number: 9676088
    Abstract: A portable linear fastener driving tool is provided that drive staples, nails, or other linearly driven fasteners. The tool uses a gas spring principle, in which a cylinder filled with compressed gas is used to quickly force a piston through a driving stroke movement, while a driver also drives a fastener into a workpiece. The piston/driver is then moved back to its starting position by use of a rotary-to-linear lifter, and the piston again compresses the gas above the piston, thereby preparing the tool for another driving stroke. The driver has protrusions along its edges that contact the lifter, which lifts the driver during a return stroke. A pivotable latch is controlled to move into either an interfering position or a non-interfering position with respect to the driver protrusions, and acts as a safety device, by preventing the driver from making a full driving stroke at an improper time.

The fastener driving apparatus is a combination of a motor driven linear motion converter; a compression cylinder; an expansion cylinder and a valve arrangement. The linear motion converter converts a rotational motion of a motor to a linear motion of a compression piston within the compression cylinder causing a gas within the compression cylinder to be compressed. The compressed gas is communicated to the expansion cylinder through the valve arrangement wherein the compressed gas expands causing an anvil coupled to an expansion piston within the expansion cylinder to move axially. The axial movement of the anvil causes a fastener to be driven into the substrate. The fastener driving apparatus is an ergonomically designed portable hand held tool providing comfort to a user, meeting safety standards and performance efficiency requirements.

  • Patent number: 8851351
    Abstract: A trigger assembly for switching one shoot mode or repeat shoot mode includes a trigger, a switch, a fixing element, a trigger plate and a torsion spring. When a user wants to switch the shoot modes of the nail gun, the user turns the switch so that the fixing element moves along the curved track of the switch and the fixing element drives the trigger plate to move on a protrusion or on a through hole simultaneously. After the user presses the trigger, the trigger plate is resisted by the protrusion so that the nail gun is in one shoot mode. In addition, when the trigger plate is vibrating on the through hole, the nail gun is in repeat shoot mode.

  • Patent number: 8777079
    Abstract: A nail gun includes a rotatable shaft which can lock a switch of a trigger of the nail gun in a nail-empty condition. The rotatable shaft has a locking portion and a driven portion extending partly into a nail magazine, such that when a nail pushing member disposed in the nail magazine reaches a predetermined position, the nail pushing member pushes the driven portion to make the rotatable shaft rotate about an axis perpendicular to a marching direction of the nails loaded in the nail magazine. As a result, the locking portion of the rotatable shaft in an initial position and spaced away from the switch will move to a locking position to be engaged with the switch. Therefore, the nail gun can shoot nails continuously until there is totally no nail in the nail gun and the nail gun is locked.

  • Patent number: 8763874
    Abstract: A portable linear fastener driving tool is provided that drive staples, nails, or other linearly driven fasteners. The tool uses a gas spring principle, in which a cylinder filled with compressed gas is used to quickly force a piston through a driving stroke movement, while a driver also drives a fastener into a workpiece. The piston/driver is then moved back to its starting position by use of a rotary-to-linear lifter, and the piston again compresses the gas above the piston, thereby preparing the tool for another driving stroke. An improved lifter design has modified lifting pins that reduce the side-forces on the driver. A pivotable latch acts as a safety device, by preventing the driver from making a full driving stroke at an improper time. An improved latch design has a more durable catching surface.
