An active-hydrogen-containing phosphorus compound is provided. Logical circuit boards 851 to 85n are each incorporated with the secondary battery box 87, fast-transient-response-type non-isolated DCDC converters 931 to 933, and a plurality of loads 951 to 953. A variety of play cards affect the overall game momentum of either team. Because the two side restraint rods are pivotally connected to two sides of the seat and connected with two ends of the major restraint rod to form a movable baggage restraint rod, when the baggage restraint rod is rotated under the seat, the baggage restraint rod may restrict the baggage under the seat.
