A staple gun with a safety device and its safety device are disclosed. The staple gun with a safety device comprises a safety device and a staple-floating unit that are installed in a housing of the staple gun. The safety device includes a safety push sheet and a switch. In a middle portion of the safety push sheet is defined an engaging slot along a staple-discharging direction, and the safety push sheet is further provided with a triggering sheet extending from an upper end thereof.
