Abstract: A nail gun of the present invention includes an adjusting portion which has elasticity. The elasticity of the adjusting portion is able to offset a thrust force of a nail pusher pushed by a magazine, so that a nail slot receives a nail only. The nail gun ensures not to shoot two sticks of nails simultaneously. The nail squeezes one side of the adjusting portion in a firing process so that the nail gun can provide sufficient space. Thereby when the nail is thicker, it can be shot by the nail gun. The present invention need not adjust by hand anymore for shooting different thickness of nails. The nail gun can not shoot two sticks of nails simultaneously.

Abstract: An ergonomically enhanced electric power tool is disclosed that incorporates a new type of user grip and control system. This grip and control system is housed in a substantially rigid control-housing sheath, which provides enhanced leverage and control over the drilling process while reducing stress on the user's hand, wrist, and arm. The tool motor is disposed substantially in parallel with the user's wrist, but on a different plane, and eliminates the traditional “pistol” type of power-tool grip. The control-housing sheath contains a grip-controller assembly that allows the user to control most major drill operations within the gauntlet-like control-housing sheath. The inventive concepts described can be applied to myriad hand-held power tools, and a detailed example for a power drill is provided.

Abstract: An ice auger driven manually by foot power through the instrumentality of a foot driven ratchet drive rotatably affixed to a set of bevel gears permanently mounted in a framework affixed to a stable base. An assymetrically shaped auger shaft with a rotatably mounted handle assembly and a permanently attached auger head is positioned vertically through, but not affixed to, the assymetrical bore of the horizontally positioned bevel gear permitting vertical movement of the shaft within the bore during operation. The combination of rotation created by the operation of the ratchet, the constant rotational force point on the auger shaft at the assymetrical bore of the horizontal bevel gear, combined with the simultaneous vertical movement of the auger shaft, results in a constantly changing point on the shaft where the bevel gear imparts rotational force. The vertical movement of the auger shaft is facilitated by the operator's downward pressure on the handle.
