description The invention provides an anti-dropping positioning device for an attached type lifting scaffold and a working method thereof. The anti-dropping positioning device of the invention comprises a guide seat which is connected with a guide-rail sleeve; a guide rail is provided with cross bars which are arranged at interval, and the guide seat is provided with an anti-dropping positioning wheel which is in sliding mesh type transmission with the cross bars; a clutch device is arranged between the wheel body of the anti-dropping positioning wheel and the shaft seat of the anti-dropping positioning wheel. During the slowly rising and dropping of the scaffold, the sudden dropping of the scaffold can cause the anti-dropping positioning wheel to generate relatively high speed of reverse rotation, and an auto-trigger triggers the clutch device to work, which causes the anti-dropping positioning wheel to be incapable of having reverse rotation and to block the cross bars at interval arrangement on guide rails so as to pr
