20090255130 | INSTRUMENT - An instrument having two branches such as a pair of scissors, or the like. The two branches thereof are connected with a coupling element, which is attached to one of the branches and extends through a hole in the other branch. The coupling element has a locking body situated on the outside of the other branch. Both the locking body and the hole are out of round so that the locking body can be brought through the hole in a certain angular position but not in another. According to the invention, the coupling element is screwed into the first branch. Furthermore, the locking body has a shape that is adapted in such a way to the shape of the hole that the coupling element can be turned by means of the second branch. | 10-15-2009 |

20110258860 | OPTIMIZED MECHANICAL ADVANTAGE CUTTING TOOL - A cutting tool and method comprises a first lever having a first jaw at one end. A second lever is connected to the first lever at a first pivot where the second lever has a second jaw that is opposed to the first jaw. A third lever is connected to the first lever at a second pivot and connected to the second lever at a third pivot such that relative movement of the third lever relative to the first lever between an open position and a closed position defines a stroke of the tool that corresponds to movement of the hand contact points on the levers toward one another. The third pivot comprises a pin engaging a cam surface where the cam surface has a shape such that the mechanical advantage may increase and decrease through the stroke of the tool and may be variable through the stroke of the jaws. | 10-27-2011 |

20120324739 | Powered Drywall Tape Cutter - A power cutter tool for applying drywall tape or plastic drywall trim product that contains a powered blade that can cut the tape or trim material by simply pressing a trigger. The cutter can be powered by a spring or springs, a motor, hydraulically or by any other means. The trigger can be a button, lever, valve or any other means for releasing a powered blade. | 12-27-2012 |
20130019481 | ELECTRIC PRUNER - An electric pruner includes a housing, a motor accommodated within the housing, a transmission mechanism, a movable blade, and a fixed blade extending from the front end of the housing. The fixed blade is fixedly mounted on the housing, and the movable blade is rotatably connected to the fixed blade via a shaft and driven by the motor via the transmission mechanism. A groove is formed on the movable blade and comprises a first and a second groove portion, the size of the first portion being greater than that of the second portion. The shaft comprises a first mating portion and a second mating portion, and is movable between a first position and a second releasing the movable blade when the shaft is in the second position. Thus, the replacement of the movable blade is very simple and convenient. | 01-24-2013 |
20130019482 | ELECTRIC PRUNER - An electric pruner includes a housing, a motor accommodated within the housing, a transmission mechanism, a movable blade, and a fixed blade extending from the front end of the housing. The fixed blade is fixedly mounted on the housing, and the movable blade is rotatably connected to the fixed blade via a shaft and driven by the motor via the transmission mechanism. A locking device manually operable by the user is arranged n the shaft for locking the movable blade, the locking device being switchable between a first position where the movable blade is locked to stay connected with the transmission mechanism and a second position where the movable blade is releasable from the transmission mechanism. Thus, the replacement of the movable blade is very simple and convenient. | 01-24-2013 |
20140041236 | Dual Mode Ratchet Pruners - Pruners and Toppers have dual mode operation in that the blade is closed with a single squeeze or with multiple squeezes and a rotatable selector selects the desired mode. The blade has a rocker arm with ratchet teeth formed in a window in the arm. The scissor handle has a radius arm which ends in a pawl which can engage the ratchet nearer the pivot axis of the blade or further from it. | 02-13-2014 |
