A motor 7 is fixed to the top of the support base 301 by bolts. The output end of the motor 7 is connected to a lower anti-slip wheel 302 through a coupling. The motor 7 drives the lower anti-slip wheel 302 to rotate, thereby driving the processing shaft to rotate, and then adjusting the straightening angle of the processing shaft.
