[0022] When it is necessary to straighten the steel pipe, first, the speed reducer motor 5 is started, the output shaft of the speed reducer motor 5 drives the rightmost conveying roller 2 to rotate, since the adjacent conveying rollers 2 are linked through the engagement of the gear one 3 and the gear two 4, therefore all the conveying rollers 2 will rotate synchronously.
