When the motor 29 is running, the bidirectional threaded rod 10 rotates in the inner cavity of the transition box 5, and then the two threaded sleeves 11 move in opposite directions on the surface of the bidirectional threaded rod 10, so that the two threaded sleeves 11 drive the powder baffle 7 to move in opposite directions in the inner cavity of the transition box 5 and the chute 8.
