The invention discloses a locking mechanism of a trailer carriage and the trailer carriage. The locking mechanism of the trailer carriage comprises a transmission shaft, two plug pins, an air bag and a swing arm. The transmission shaft is pivoted to the sliding frame and extends in the length direction of the sliding frame. The two bolts are movably connected to the two sides of the sliding frame in a penetrating mode respectively and can move between a first position contained in the sliding frame and a second position protruding out of the side edge of the sliding frame in the width direction of the sliding frame, connecting pieces are arranged between the two bolts and the transmission shaft respectively, one ends of the connecting pieces are connected to the transmission shaft in a pivoted mode, and the other ends of the connecting pieces are connected to the bolts in a pivoted mode. One end of the connecting piece is staggered with the rotating axis of the transmission shaft relative to the rotating axis of the transmission shaft; one end of the swing arm is connected to the transmission shaft, the other end of the swing arm forms a connecting base, one end of the air bag is connected to the sliding frame, and the other end of the air bag is connected to the connecting base. The sliding frame locking mechanism does not need to consume physical power, is easy to operate and convenient to use, and improves the automation degree.
