A gardening spray gun may include a main body, a shaft, a retaining buckle, and a control unit. In one embodiment, the control unit is connected with the shaft, so the water coutput can be continuously maintained out without keeping a constant pressure on the spray gun, which saves the gardener's energy, effectively reduces the hand burden, and maintains a stable water outflow volume each and every time. The water spray gun in the present invention can be easily assembled by putting the shaft, the retaining buckle and the control unit together. |
