13. The binding head tool of claim 1, further comprising an alarm module mounted on the machine body for generating an alarm message when a change in position between the binding module and the machine body exceeds a threshold.
14. The binding head tool of claim 13, wherein the alarm module comprises:
the first distance measurement sensing piece is fixedly arranged with one of the binding module and the machine body;
the overtravel sensor is fixedly arranged on the other one of the binding module and the machine body and is used for measuring the relative distance between the overtravel sensor and the first distance measurement sensing piece;
and the alarm signal generating part is used for generating an alarm signal when the relative distance measured by the overtravel sensor exceeds the threshold value.
15. The binding head tool of claim 1, further comprising a zero position detection module for detecting whether the binding head tool returns to a starting position relative to the machine body in a non-operational state.
16. The binding head tool of claim 15, wherein the zero detection module comprises:
the second distance measurement sensing piece is fixedly arranged with one of the binding module or the machine body;
and the zero position sensor is fixedly arranged with the other one of the binding module or the machine body and is used for measuring the relative distance between the zero position sensor and the second distance measuring sensing piece.
