A gardening scissor includes a first cutting unit, a second cutting unit, and a control rod. Each of the first and second cutting units has a tool portion, and one end of each of the tool portions has a first handle and a second handle. The first and second cutting units are pivotally connected together through first and second through holes. An axial hole is formed near the first through hole, and one side of the axial hole has a gap to connect with the step-shaped space. An extending wing that is protruding out from the second handle is formed at a rear portion of the tool portion. When the control rod is inserted into the axial hole and connected with a stopping unit, the control rod can be restricted by the stopping unit and cannot be laterally separated from the axial hole.
