A pair of conventional gardening shears in accordance with the prior art shown in Fig. 5 comprise two handles 80 pivotally connected with each other by a pivot shaft 71 and each having a distal end formed with a blade 00 SThus, when a user exerts a force on the two handles 80, the two handles 80 are movable toward each other, so that the blades 70 of the handles 80 are movable toward each other to perform a cutting action so as to cut a workpiece, such as the branch or the like. In such a manner, the handles 80 perform a linkage action by the length of each of the handles 80, so that the blades 70 of the handles 80 have a force to perform the cutting action. However, the cutting force of the blades 70 applied by the handles 80 is not large enough to cut a larger and harder workpiece, so that the user has to exert a larger force on the handles 80 so as to cut the larger and harder workpiece, thereby wasting the user's manual work, and thereby greatly causing inconvenience to the user when operating the gardening shears.

In accordance with the present innovation, there is provided a pair of gardening shears, comprising a first handle having an end portion formed with a mounting seat, the mounting seat having a first end formed with a pivot hole and a second end formed with a drive arm, a first cutting member pivotally mounted on the mounting seat and having a first end formed with an adjusting la COMS ID No: ARCS-197968 Received by IP Australia: Time 14:14 Date 2008-07-11 11/07 2008 FRI 16:14 FAX +64 4 472 3358 0006/020 00 0 slot, a mediate portion formed with a pivot bore pivotally mounted on the drive arm of the mounting seat and a second end formed with a first blade, a second cutting member pivotally mounted on the mounting seat and having a first end formed with a pivot hole pivotally mounted on the pivot hole of the mounting seat, a mediate portion formed with a linking rod mounted in the adjusting slot of the first cutting member and a second end formed with a second blade aligning with the first blade of the first cutting member, and a second handle secured on the first end of the second cutting member to move the second cutting member and movable relative to the first handle.

The primary objective*of the present innovation is to provide a pair of gardening shears having an energy-saving effect.

Another objective of the present innovation is to provide a pair of gardening shears, wherein 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 end of the first cutting member upward 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.
