A safety device for a nailer includes a pushing end located at a first end of the safety device and the pushing end is movably inserted into the nose or the magazine and located beside heads of the nails. A second end of the safety device is biased by a spring and located beside the plate of the trigger unit of the nailer. One of the nails in the passage 40 has its tip extending out from the nose and when the tip is pushed to against the object to be nailed, the nails are shifted a distance and push the pushing end of the safety device to activate the plate of the trigger unit. When the trigger unit is pulled, the valve unit is activated and the nail that contacts against the object is precisely sent into the object.
