1. A child safety seat for use on a vehicle seat, the vehicle seat having a safety belt, the child safety seat comprising:

  • a seat base having a seat assembly portion and a backrest portion, the backrest portion having at least one fixing hole;

    a seat panel openably pivoted to the seat assembly portion for rotating between an open position and a closed position;

    a seat body disposed on the seat panel; and

    a retractable plunger disposed on the seat panel corresponding to the at least one fixing hole and slidable between an engaging position and a retracted position;

    wherein when the seat panel rotates to the open position, the safety belt passes over the seat base for attaching the seat base to the vehicle seat;

    when the seat panel rotates to the closed position, the seat panel clamps the safety belt cooperatively with the seat base;

    when the seat panel is located at the closed position to make the retractable plunger aligned with the at least one fixing hole, the retractable plunger pops out to the engaging position to be inserted into the at least one fixing hole for fixing the seat panel to the seat base;

    during rotation of the seat panel from the open position back to the closed position, the backrest portion biases the retractable plunger to the retracted position.
