20120005902 | WIRE CUTTER HEAD FOR PREVENTING MISALIGNMENT OF THE CUTTING BLADES - A wire cutter head for preventing misalignment of cutting blades comprises two cutting members, the two cutting members respectively have a cutting face and a handle neck at two ends and are pivoted together at a middle position. The cutting face is a stepped inclined surface having a stopping surface formed with an inclined angle at an approximant middle section, such that the two stopping surfaces are flat with respect to each other, and a blade is formed at a lower edge of the cutting face. The handle neck is a plate used for controlling the pivot angle of the cutting blades. When the handle necks of the cutting members are pressed to rotate the cutting faces, the two facing stopping surfaces and the blades of the two cutting members contact each other. Therefore, the linear contact between the blades is free from misalignment and no offset gap between the blades occurs during operation. | 01-12-2012 |
20120030951 | Lopper devices for pruning trees and brushes - Disclosed are shears are used for trimming bushes, trees, and brush. The loppers have the cutting blade which performs the cutting action and a counter edge for the cutting blade to work in conjunction. These loppers also have the addition of clamping jaws which will hold the severed limb. A user amputates a tree limb and the severed or orphaned limb falls helplessly to the ground, but these loppers clamp onto that limb when the cutting operation is performed. After the cut is made, the user can move the limb to a specific location, then decompresses the loppers and drop the limb as intended. | 02-09-2012 |

20130145628 | SNIPS INCLUDING A JAW STOP - A hand tool for actuation between a closed state and an open state includes a first jaw member having a first blade portion and a first extension portion. The first blade portion defines a first cutting edge having a first substantially convex profile along its entire length. A first handle member is coupled to the first extension portion. A second jaw member is pivotably coupled to the first jaw member. The second jaw has a second blade portion and a second extension portion. The second blade portion includes a second edge having a second substantially convex profile along its entire length. A second handle member is coupled to the second extension portion. The first jaw member and the second jaw member define a jaw stop that inhibits the first blade portion and the second blade portion from opening beyond a predetermined jaw angle. | 06-13-2013 |
20130160301 | SHEAR - The shear of the present invention includes a clipper, an elastic element and a holding portion. A first cutter of the clipper forms a pressing face, and a second cutter of the clipper forms a leaning face corresponding to the pressing face. When the clipper splays to a maximum angle, the pressing face and the leaning face touch each other, and the elastic force is accepted by the leaning face. Because the first cutter and the second cutter are made of a same material and the hardness of the first and the second cutters is the same, the contact faces of the cutters are not abraded after several times touching. Thereby, the shear of the present invention is much more durable. | 06-27-2013 |
20130232797 | Compound Action Snips - A compound action snips includes first and second handles pivotally connected to each other, and first and second blades.
