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.

Abstract: A self-contained button attachment kit includes a pair of buttons, fastener clips and a tool for dispensing a fastener from a fastener clip to reattach a button to an article of clothing.

In operation, the front cap serves as an anvil that supports the article and button to be attached. With a fastener clip loaded into the holder, the needle is then inserted through the pair of items. Displacement of the handle relative to the holder causes an ejection rod to dispense the cross-bar of a fastener through the needle, thereby completing the attachment process.

Abstract: An auto hammer having a housing having a grip portion defining a central axis and a head assembly including a striking device which has a striking rod defining a central axis.

Abstract: A moving-positioning means of belt-fastening apparatus including a head and an anvil plate on which a row of fastener holes disposed, a row of positioning grooves are disposed in one side of the anvil plate; said positioning grooves are parallel to said fastener holes and the spaces of the positioning grooves are identical to those of said fastener holes; and a positioning strip disposed on the head is compatible with said positioning grooves. Since the positioning grooves and the fastener holes are separately disposed on the anvil plate, the positioning strip may be inserted into the positioning grooves to be located when the head moves. Therefore the fastener holes are no longer used for the location, and the movement of the head is not restricted to the fastener holes, which means the head may move in the whole area of the frame no matter whether the fasteners are inserted into the fastener holes or not.
