The box driver prepared by the present invention comprises a head (10) which is formed at one end of an accommodating groove (11) for accommodating a square shaped bolt or nut; a shaft (20) which is extended from the other end of the head (10); and a handle (30) which is formed at the end of the shaft (20) in order to be gripped by the hand of a user. The handle (30) comprises a horizontal stick (31) which is fixed such that the center part thereof can be horizontally integrated with the end of the shaft (20) in order to be at right angles with the longitudinal direction of the shaft (20), and is gripped by the palm and fingers of the user; and a vertical stick (32) whose one end is integrated and fixed to the horizontal stick (31) while the other end is supported by one end of the horizontal stick (31) in order to be at right angles with the longitudinal direction of the horizontal stick (31), and is supported between the thumb and index finger of the user in order to convey the thumb power to one end of the horizontal stick (31).
