• and
• a second movable beam comprising a third moveable edge and a fourth movable edge that are opposite, the third moveable edge extending along a curve and the fourth movable edge having a second curved segment and a second straight segment that are connected to each other;
• wherein the first movable beam and the second movable beam are respectively arranged on two opposite sides of the fixed beam, the first movable beam is movably arranged on the turnout platform between a first position and a second position, and the second movable beam is movably arranged on the turnout platform between a third position and a fourth position;
• wherein when the first movable beam is at the first position, the second movable beam is at the third position, the first movable beam is separated from the fixed beam, and the second movable beam and the fixed beam form a first passage;
• wherein when the first movable beam is at the second position, the second movable beam is at the fourth position, the second movable beam is separated from the fixed beam, and the first movable beam and the fixed beam form a second passage;
• and
• wherein the first passage is a curved beam and the second passage is a straight beam;
• wherein the first fixed edge extends along a straight line and the second fixed edge extends along a curve:
• wherein when the second movable beam is at the third position, the second fixed edge and the second curved segment form a continuous curved line;
• and
• wherein when the first movable beam is in the second position, the first fixed edge and the first straight segment form a continuous straight line.
