11. The binding head tool of claim 10, wherein the alarm module comprises:
the first distance measuring sensing piece is fixedly arranged with one of the binding module and the machine body;
the overtravel sensor is fixedly arranged with the binding module and the other machine body and is used for measuring the relative distance between the overtravel sensor and the first distance measuring sensing piece;
and the alarm signal generating part is used for generating an alarm signal when the relative distance measured by the over-travel sensor exceeds the threshold value.
12. The binding head tool of claim 1, further comprising a zero detection module for detecting whether the binding module has returned to a home position relative to the body in a non-operational state of the binding head tool.
13. The binding head tool of claim 12, wherein the zero detection module comprises:
the second distance measuring sensing piece is fixedly arranged with one of the binding module or the machine body;
the zero sensor is fixedly arranged with the binding module or the other machine body and is used for measuring the relative distance between the zero sensor and the second distance measuring sensing piece.
