Claim:
1. A battery box structure for receiving at least one battery therein, comprising: an enclosure defining a first receiving groove which penetrates through a bottom surface and a lower portion of a front surface of the enclosure; a first circuit board mounted inside the enclosure and located above the first receiving groove, at least one pair of conductive terminals being fastened to the first circuit board, a tail end of each of the conductive terminals being arched downward to form a resilient contact portion projecting into the first receiving groove; a push button elastically disposed between the enclosure and the first circuit board, the push button being partially exposed outside the enclosure; and a battery holder defining a holding groove which penetrates through a rear surface of the battery holder, the battery holder including at least one pair of conductive pads fastened to a top of the battery holder, the battery being placed in the holding groove of the battery holder, a bottom end of the push button being buckled with a top end of the battery holder, the battery holder together with the battery being assembled upward in the first receiving groove of the enclosure, each of the conductive pads being corresponding to and electrically contacting the resilient contact portion of one of the conductive terminals, the resilient contact portion of each of the conductive terminals being compressed to accumulate elastic force, the conductive pads being electrically connected with an anode and a cathode of the battery, respectively, wherein when the push button is pressed rearward, the bottom end of the push button breaks away from the top end of the battery holder, the resilient contact portions of the conductive terminals release the elastic force to push against the conductive pads of the battery holder to make the battery holder move downward for a distance, so that the battery holder is automatically ejected out of the enclosure, wherein the enclosure includes a first enclosure and a second enclosure, the first enclosure defines the first receiving groove which penetrates through a bottom surface and a lower portion of a front surface of the first enclosure, the second enclosure is fastened to a front of the first enclosure and covers up a top of the first receiving groove, wherein a top sidewall of the first receiving groove is recessed inward to form a first locking groove, the battery holder has a base body, and a protruding block protruded upward from a top of the base body, the protruding block is received in the first locking groove, and wherein a top sidewall of the first locking groove opens an opening, the first circuit board is mounted inside the first enclosure, and is located above the first receiving groove, the first circuit board defines a recess penetrating through a bottom face of the first circuit board, a top sidewall of the recess protrudes downward to form a protruding board projecting beyond the bottom face of the first circuit board, the recess is divided into two notches by the protruding board, a bottom end of the protruding board projects into the first receiving groove through the opening, the push button includes a pressing portion which has a base portion, two opposite sides of a bottom surface of the base portion protrude downward to form two extending boards, a bottom end of each of the two extending boards is connected with a hook-shaped buckling portion, each buckling portion is located in front of the first circuit board and is corresponding to one of the notches.
