By providing a second motor, a second gear, a rotating shaft, a half-toothed gear, a cam and a top plate, the output end of the second motor drives the second gear to rotate, so that the second gear is meshed with the half-toothed gear, so that the half-toothed gear drives the rotating shaft to rotate, so that the cam lifts the top plate), thereby supporting the bottom of the corrugated cardboard box, reducing the process of workers needing to support the cardboard box during binding, reducing labor intensity, and ensuring worker safety.
