1. A tamper-proofing electronic seal, comprising:
a shell, a lead seal rope, and a lead seal label arranged in the shell, wherein the lead seal label comprises a chip, an antenna circuit, a power supply, a power switch, and a potential detection circuit;
the antenna circuit is electrically connected to the chip;
the power supply is electrically connected to the chip through the power switch;
both ends of the potential detection circuit are electrically connected to the antenna circuit and the chip respectively; and
a fixing hole is provided at a position, adjacent to the potential detection circuit, of the interior of the shell;
a locking hole is provided at a position, corresponding to the power switch, of the interior of the shell;
the fixing end of the lead seal rope passes through the fixing hole and is clamped in the shell;
when the locking end of the lead seal rope passes through the locking hole, the locking end is fixedly connected to the shell and closes the power switch; and
when the middle part of the lead seal rope is disconnected, the lead seal rope passes through the end of the fixing hole to move towards the potential detection circuit and disconnect the potential detection circuit.
