The propping block 22 of the electromagnetic lock assembly 2 is a long block, and the transmission member 23 is connected to one end of the propping block 22 to drive the propping block 22 to move along the horizontal direction. When the transmission component 23 drives the abutting block 22 to move to the limiting position, one end of the abutting block 22 happens to be located below the pressing piece 43 of the locking hook component 4, so that the abutting block 22 can abut against the pressing piece 43 of the locking hook component 4, the pressing piece 43 cannot be pressed down, the limiting pressing piece 43 cannot move, and the charging gun 100 is fixedly clamped in a charging seat of the electric vehicle by using the clamping hook 42 of the locking hook component 4.

When the transmission component 23 drives the propping block 22 to move away from the limiting position, the pressing member 43 of the locking hook assembly 4 can be pressed down, so that the rod 41 of the locking hook assembly 4 pivots to drive the hook 42 to move, and the charging gun 100 can be pulled out from the charging seat of the electric vehicle.

When power is cut off accidentally during charging, the electromagnetic lock assembly 2 cannot be actuated, so that the charging gun 100 is locked in the charging seat of the electric vehicle. The user can use the vehicle to join in marriage the key, with the vehicle join in marriage in the key inserts the slot 314 of the unlocking piece 3 in the casing 1 activity groove 12, promote unlocking piece 3 and remove along activity groove 12, make the ejector pin 32 keep away from the one end of kicking block 31 and stretch into in the installation cavity 11, and insert in the unlocking hole 212, promote electromagnetic lock subassembly 2 to support the round pin axle 221 of kicking block 22, make to support kicking block 22 and remove and leave the limit position, and then make the pressing member 43 of trip subassembly 4 can be pressed down, let the rifle 100 that charges pull out from the charging seat, avoid causing inconvenience to electric vehicle's driving.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
