The utility model relates to a leakage-proof safety device for taking a hydrogen peroxide solution. The leakage-proof safety device comprises an outer shell, a rotary knob, a cam shaft, a first cam, a second cam, a micro switch, a pipette tip and a movable drawer. The rotary knob is connected to the cam shaft. The first cam and the second cam are connected to the cam shaft. The micro switch and the pipette tip are located below the rotary knob. The leakage-proof safety device for taking the hydrogen peroxide solution can prevent weeping, dripping corrosion and other conditions caused in the solution taking process, thereby avoiding the situation that the health of an operator is damaged due to the fact that the operator is contacted with liquid state hydrogen peroxide indirectly or directly, and realizing safe liquid taking. On the other hand, the leakage-proof safety device for taking the hydrogen peroxide solution can effectively improve the absorption work efficiency and the utilization rate of the hydroge
