1. A connector lock structure having a guarding function adapted for being docked with a docking connector, the docking connector having a metal casing, a bottom of the metal casing defining a blocking groove, the connector lock structure comprising:
an insulating body;
a plurality of terminals, the insulating body being molded around the plurality of terminals by an injection molding technology;
a shell surrounding a peripheral surface of the insulating body, the shell having a bottom plate, the bottom plate being mounted to a bottom surface of the insulating body;
a locking assembly including at least one lacking groove and at least one elastic arm, a front end of the bottom plate of the shell defining the at least one lacking groove extending longitudinally, the at least one elastic arm being formed in the at least one lacking groove, a tail end of the at least one elastic arm having a hook structure, the hook structure being cooperated with the blocking groove of the metal casing of the docking connector, the hook structure being buckled in the blocking groove of the metal casing of the docking connector;
a sliding board slidably mounted to the bottom surface of the insulating body, the sliding board sliding along a docking direction of the connector lock structure;
a pressing element mounted in the insulating body, the pressing element being mounted on a top surface of the sliding board, the sliding board being slidably mounted under the pressing element, the pressing element being tightly cooperated with the sliding board, one end of the pressing element having a locking portion, an outer surface of the locking portion having a keyhole, the locking portion projecting beyond one side surface of the insulating body, the locking portion projecting beyond one side surface of the shell;
an unlocking tool inserted in the keyhole of the locking portion of the pressing element;
wherein the unlocking tool is rotated to make the unlocking tool drive the locking portion of the pressing element to rotate, and then the pressing element drives the sliding board to move horizontally to abut against the at least one elastic arm, so that the at least one elastic arm is locked to the blocking groove of the metal casing of the docking connector.
