When the carbon fiber prepreg is flattened and processed, the motor 9 can be started, and the bidirectional screw rod 10 arranged at the output end is rotated by the motor 9. When the bidirectional screw rod 10 rotates, the two groups of screw nut pairs 11 are simultaneously moved to the center. When the screw nut pairs 11 move, the connecting plates 12 and the air plates 13 on one side are simultaneously moved to the center.
