US Patent 7178245 Gardening shears having energy-saving effect

A pair of gardening shears include a first handle, a first cutting member, a second cutting member, and a second handle. Thus, when the second cutting member is movable toward the first cutting member to perform the cutting action, the linking rod of the second cutting member pushes the first cutting member to drive the first cutting member to pivot about the drive arm of the mounting seat to push the first blade of the first cutting member downward, so that the first blade of the first cutting member is further movable toward the second blade of the second cutting member so as to enhance the cutting force of the first cutting member and the second cutting member thereby enhancing the working efficiency of the gardening shears.
