081302000 | Antipodal jaw surfaces move apart as handles approach (e.g., outwardly expanding jaws) | 9 |
20080264216 | Snap Ring Pliers - The jaw portion comprises cross levers centrally connected by a rotatable central axis with a throughbore and outwardly connected by lever pivots to parallel jaws (within clots at one end) with tapered operating tips at either end. | 10-30-2008 |
20090193942 | Spreading Pliers - The invention relates to pliers for changing the distance of two activation surfaces of a connection or fitting for conduits. The change of the distance correlates with an elastic or plastic deformation of at least one component of the fitting including a radial crimping process. | 08-06-2009 |
20100288085 | MIG WELDING PLIERS - An improved MIG welding pliers is disclosed, which allows faster and easier removal of spatter form a MIG welding nozzle, thereby improving welder productivity. Embodiments of the present invention provide a rounded file on the outer surface of each of the pinchers of the pliers. In one embodiment, each pincher has a different file surface. The rounded file surface provides for improved spatter removal, and eliminates the need for waxes and spatter control products which degrade the contact tip and nozzle, hastening the need for their replacement. Therefore, embodiments of the present invention increase the efficiency of a MIG welding operation, as less time is spent removing spatter from nozzles, and thus, more time is available for welding. Furthermore, by avoiding the use of waxes, costs are reduced since nozzles and contact tips do not need to be replaced as frequently. | 11-18-2010 |
20110154957 | PLIERS FOR CHAIN LINK - A pliers for chain link includes a left pliers body, a right pliers body, a pin and an elastic member. The left pliers body and the right pliers body are connected either in a parallel form or in a cross form. Center portions of the left and right pliers bodies are connected by the pin. The elastic member is located between the left and right pliers bodies. The left and the right pliers bodies includes clamping portions which have jaw parts. The jaw parts have curved edges thereon. The jaw part of the left pliers body corresponds to the jaw part of the right pliers body. The curved edges are adapted to lean against chain pins of chain plates to stabilize the operation of clamping. | 06-30-2011 |
20110154958 | DUAL-PURPOSE PLIERS ADAPTED TO CHAIN LINK - A dual-purpose pliers adapted to chain link applies to concurrently promote a separation of two first jaw parts or an approach of two second jaw parts, which is conducive to a convenient detachment or assemblage of a master chain link via merely using a driving tool. Further, each jaw part forms a curved brim represented by an arcuate contour, a serrated shape, or the combination thereof. Accordingly, the curved brim serves to encircle and lean against a periphery of a chain pin of the chain for a stable manipulation. | 06-30-2011 |
20110214538 | Pair of Pliers with Dual Functions for Snap Ring - A pair of pliers that is switchable between first and second mode, the pair of pliers comprises a handle assembly including a pair of hand grips pivotally connected to each other and two connected ends respectively extending from the pair of hand grips; a jaw assembly, which is installed onto the connected ends and adapted to couple to a ring, including a plate having a slider rail and two first jaws joined together, with each first jaw having a channel and a pin which is disposed in and slideable along the channel; and a drive member, which is provided between the first jaws and operable between an original position and a moveable position, including a positioning shaft slideably disposed along the slider rail of the plate. | 09-08-2011 |
20120198971 | Knot Loosening Device - A knot loosening device and method of use. A pointed member is disposed, for inserting into the knot, followed by a midsection with a pry arm. Once the midsection is engaged, the pry arm is actuated by means of a lever arm which can be viewed as outwardly expanding jaws or jaw surfaces which have the effect of spreading or loosening the knot. | 08-09-2012 |
20140202291 | C-TYPE PLIERS - A C-type pliers contains a first elongated jaw including a first recess and a third recess, a second elongated jaw including a second recess and a fourth recess; a first handle further including a first notch, and a second handle including a second notch; a switching unit including a first cover, a second cover, a shaft extending outwardly from the second cover and used to drive the first cover and the second cover simultaneously, the shaft pivots the first handle, the second handle, the first elongated jaw, and the second elongated jaw; a switching unit also including a first retainer, a second retainer, when the first retainer retains in the first recess, the second retainer retains in the fourth recess simultaneously, and when the first retainer retains in the second recess, the second retainer retains in the third recess synchronously. | 07-24-2014 |
