At the same time, the rotating wheel 11 presses the pressure plate 26, and the pressure plate 26 presses down the pressure plate spring 27. The pressure plate spring 27 presses against the bearing cover 28, driving the connecting rod 30 and the boss 32 to move downward, so that the boss 32 is pressed down to leave the boss groove 33 on the lower end surface of the turntable 25, and the rotating wheel 11 drives the turntable 25 to turn 90 degrees. After the rail car leaves the turning mouth, the boss spring 35 bounces the boss 32 into the boss groove 33, locking the turntable 25 to prevent the deviation of the trolley turning caused by the rotation of the turntable.
