A pair of gardening shears include two opposite cutters (10), two handles (30) connected with the cutters respectively, and two pivot units (20) each pivotally connected with a respective one of the cutters and a respective one of the handles. Thus, each of the handles is pivotable relative to a respective one of the cutters by a respective one of the pivot units to change the angle between each of the handles and the respective cutter and to change the pitch angle of each of the handles freely.
