Moreover, when the electronic tag 159 moves relative to the inductive identification component 250, the strength of the signal generated by the inductive identification component 250 is different, so the position of the electronic tag 159 can be calculated according to the signal strength of the electronic tag 159, and the position of the electronic tag 159 It is related to the size of the direction change angle of the cutter head 130 , therefore, the size of the direction change angle can be calculated according to the strength of the signal generated by the induction identification component 250 , so as to achieve the purpose of identifying the size of the direction change angle. The specific implementation is as follows: when the electronic tag 159 moves forward with the push-pull member 145, the sensing and identification component 250 gradually moves away from the electronic tag 159, and when the electronic tag 159 moves to the farthest end, the angle at this time is calibrated to be the maximum direction change angle value , when the electronic tag 159 moves in reverse to the nearest end, it is calibrated to the minimum change angle (ie, 0 degrees), and the host 600 identifies the signal strength of each position point from the nearest end to the farthest end to distinguish the change of the cutter head 130. The size of the direction angle (since the signal sensed from the nearest segment to the farthest moving range will not be completely linear, the position angle can be calibrated segment by segment in the control software of the host 600), so as to realize the identification The size of the turning angle of the cutter head 130 .
