the wrench induction rod is a strip-shaped rod which can rotate around a rear wrench induction rod supporting rod, an induction block extending into the lock body shell is arranged at the rear part of the wrench induction rod, and the wrench induction rod supporting rod is arranged on the lock body shell; the reset torsion spring is arranged on the wrench induction rod supporting rod, so that the initial position of the wrench induction rod is close to the end of the outer lock tongue; when the wrench induction rod rotates to a position far away from the outer lock tongue, the induction block rotating along with the wrench induction rod triggers the wrench position inductor to send out a switch wrench in-place signal to the MCU;
the motor is electrically connected with the MCU through the driving module.
2. The intelligent locking device for the manual turnout spanner according to claim 1, wherein the spanner position sensor comprises a first reed switch and a first permanent magnet, the first permanent magnet is arranged on the sensing block, and the first reed switch is arranged at a position where the spanner sensing rod can interact with the first permanent magnet when the spanner sensing rod is at a position far away from the outer lock tongue; the first reed switch is electrically connected with the MCU.
3. The intelligent locking device of an artificial turnout wrench as claimed in claim 1, wherein the tongue position sensor comprises a second reed switch and a second permanent magnet, the second permanent magnet is arranged on the outer tongue, and the second reed switch is arranged at a position where the outer tongue can interact with the second permanent magnet when in a locked state where the outer tongue is extended and locked by the lock pin; and the second reed switch is electrically connected with the MCU.
4. The intelligent locking device for an artificial switch wrench as claimed in claim 1, wherein the identification module comprises a sensing card identification module and/or a biometric identification module for reading the identification information of the operator.
5. The intelligent locking device for the manual turnout wrench as claimed in claim 1, comprising an acousto-optic warning module electrically connected with the MCU.
6. The intelligent locking device for the manual switch wrench as claimed in claim 1, wherein a battery is included, and the control device is connected with the battery.
