| 20140026721 | DEVICE FOR ASSEMBLING AND DISASSEMBLING AN OIL FILTER TANK - A device for assembling and disassembling an oil filter tank has a clamp module, a base plate, two elbow plates, two restricting elements, and a rotating base. The clamp module has a pair of clamp plates. Each clamp plate has a slipping portion, and the slipping portion has a restricting hole. The base plate is mounted on the clamp plates. The elbow plates are pivotally mounted on the slipping portions respectively. The restricting elements are inserted slidably in the restricting holes respectively and are fixed on the base plate. The rotating base is pivotally mounted on the elbow plates and has an adapter. When the clamp plates are separated from each other, the restricting elements can ensure that the clamp plates move parallelly, such that stability and strength of the device can be enhanced. | 01-30-2014 |
| 20140053693 | Adjustable Socket - An adjustable socket including a housing designed on a longitudinal axis, with a series of grooves extending longitudinally along the interior wall. A disc with guide slots intruding obliquely off-center from the perimeter is locked into position within the housing. Jaw members with bottom stems and cams are mounted in the disc guide slots, free to move laterally along fixed paths. An axially rotatable drive core with a cam surface is positioned within the housing, engaging the cam of each jaw. Rotation of the drive core forces the jaws to travel inwardly along the disc guide slots as dictated by the spiraling guide elements of the cam surface, to be forced against a fastener within the jaws. A locking mechanism holds the jaws in position on the fastener. Release of the locking mechanism allows rotation of the drive core in the opposite direction to release the fastener. | 02-27-2014 |
