The working principle of the invention is as follows: when the driving mechanism drives the lower driving shaft 5 to rotate, power is transmitted to the upper driving shaft 5 through the meshing transmission of the transmission wheel 16, the output wheel 13 and the driven wheel 14, so that the two driving shafts 5 rotate synchronously, the shaft lever is positioned between the two traction rollers 4 and contacts with the traction rollers 4, and the traction rollers 4 are matched with each other under the driving of the driving shafts 5 to realize traction and feeding of the shaft lever. When the traction length reaches the length required by cutting, the traction roller 4 stops rotating under the drive of the driving shaft 5, so that the shaft lever is fixed. The lower module 6 and the vertical module 7 are mutually matched to drive the bracket to move, and the saw blade 8 works under the drive of the output motor to realize the cutting operation of the shaft lever.
