The body (50) has a muzzle (502) from which a nail is shot. The nail magazine (52) is attached to the body (50) for containing nails inside and communicates with the muzzle (502) in the body (50). The pad supplier (54) connected to the body (50) and contains pads inside. The pad holding device (60) is mounted between the pad supplier (54) and the body (50) to hold one pad to align with the muzzle (502). When a nail is shot from the muzzle (502), the pad held in the pad holding device (60) will be extended by and shot with the nail. The pad holding device (60) comprises a base plate (62), a middle plate (64) and an outer cap (66). The base plate (62) is attached to the body (50) and has a through hole (622) aligning with the muzzle (502). The middle plate (64) is attached to the base plate (62) to define a pad channel between the base plate (62) and the middle plate (64). The middle plate (64) has a holding hole (644) aligning with the through hole (622) in the base plate (62) and the muzzle (502). The outer cap (64) is attached to the middle plate (64) and has an outlet (662) aligning with the holding hole (644) in the middle plate (64) and the through hole (622) in the base plate (62). To keep the pad from escaping from the holding hole (644) and the outlet (642) directly before a nail being shot, the diameter of the holding hole (644) is slight smaller than that of the pad. When a nail is shot from the muzzle (502), the shot nail will extend through the pad and take the pad to pass through the holding hole (644) and the outlet (662) to be shot with the nail. When the pad is shot with the nail, the pad will slightly deformed to allow the pad to pass through the holding hole (644).
