20140178150 | WOOD SCREW - A wood screw provides a plurality of auxiliary cutting areas disposed on a bottom surface of a head and a flat area formed in any two adjacent auxiliary cutting areas. Each auxiliary cutting area includes at least two cutting grooves disposed at intervals and formed on the bottom surface, and a cutting edge formed at a convergence of the connective cutting grooves. When the bottom surface contacts the surface of the wood, the cutting edge cuts and scrapes off burrs generated around the drilling hole, and the scraped burrs are accommodated in the cutting grooves to prevent the burrs from exposing to the head after screwing. Further, the head is tightly screwed on the wood to enhance the screwing stabilization. | 06-26-2014 |
20140178149 | FASTENER CAPABLE OF SPEEDILY SCREWING - A fastener capable of speedily screwing provides a plurality of blocks on a bottom surface of a head and an accommodating area formed between any two adjacent blocks. Each block includes a first wall arranged at one side of the accommodating area and extended upward from the bottom surface, a second wall extending from the first wall to the other side of another adjacent accommodating area, and a cutting edge formed at a convergence of the first wall and the second wall. In screwing, the blocks assist in cutting to achieve a speedy screwing effect, and the accommodating area allows the cutting debris generated accordingly to be received therein so as to remain a firm engaging force between the fastener and an object. Further, there is no extra cutting debris protruding out of the object after screwing, which increases the flatness, and also enhances the screwing force of the fastener. | 06-26-2014 |
20130243547 | SCREW CAPABLE OF RAPIDLY DRILLING AND CUTTING - A screw capable of drilling and cutting includes two inclined cutting planes with a cutting edge formed on a convergence of the cutting planes. A tapered positioning member extends from the convergence of the cutting planes, where the cutting edge is divided into dual sub cutting edges by means of the positioning member. Each sub cutting edge has an inclined angle. An included angle included by the sub cutting edges is smaller than 180 degrees. Threads spiral on a shank and extend to the sub cutting edges. Setting the positioning member against on an object permits a steady performance during the first stage of screwing. Subsequently, the sub cutting edges provides a scraping effect on the object during drilling. Torque is reduced and drilling speed is promoted. | 09-19-2013 |
20110245856 | POROUS ACUPUNCTURE NEEDLE - A porous acupuncture needle includes a needle portion for puncturing the outer skin of human body, and an operation portion for being held and handled by a user. The needle portion includes a needle body, a porous layer formed by a plurality of micropores on the surface of the needle body, and a charge layer covering on the surface of the porous layer. When performing acupuncture, the affinity provided by the charge layer makes the human tissues to attach to the needle portion more easily. Moreover, during twirling the needle, the porous layer also increases the capability to affect the surrounding tissues and therefore the stimulation to the acupuncture point. | 10-06-2011 |
