In this embodiment, the output voltage of the gun insertion detection module 2 is 2.63V when inserting the gun, and 0.47V when pulling the gun. This facilitates a quick test of the process of inserting or pulling a gun. The gun locking module 3 comprises a second optical coupler U2, a first field-effect tube Q1 and a second field-effect tube Q2, the second optical coupler U2 is connected with the signal output end of the MCU 1, the output end of the second optical coupler U2 is respectively connected with the first field-effect tube Q1 and the grid G of the second field-effect tube Q2, the first field-effect tube Q1 and the drain D of the second field-effect tube Q2 are connected with each other and are connected with the anode EL + of the electronic lock at the charging interface.
