The left and right symmetrically distributed third rods 5 are fixedly installed, A through hole 7 is opened in the middle of the lower end of the plug housing 1, and a wire 8 is arranged inside the through hole 7. The wire 8 includes a first outer layer of rubber and two wires 6, and the wire 6 includes a second outer layer of rubber and a metal conductor. The two wires 6. One end located inside the plug housing 1 passes through the inner side of the third rod 5, the outer side of the second rod 4, and the inner side of the first rod 3 on the same side respectively, and is fixedly connected with the plug copper sheet 2 on the same side. The utility model has a simple structure, a first rod 3, a second rod 4 and a third rod 5 are arranged inside the plug housing 1, and the two wires 6 are respectively passed around the first rod 3, the second rod on the left and the same side through the winding The rod 4 and the third rod 5 make it difficult for the wire 6 to move inside the plug housing 1 through the friction between the first rod 3, the second rod 4 and the third rod 5 and the wire 6 and the action of the metal inside the wire 6. When an external force acts on the wire 8, the wire inside the plug housing 1 will not move under the action of the friction force, and the wire 6 transmits the force to the first rod 3, the second rod 4 and the third rod 5, thereby Forcing the plug to fall off the socket, the device has a simple structure and a novel concept. The wire is wound around the column, and the wire is fixed inside the plug shell under the action of friction and the metal inside the wire, so that the wire and the copper sheet of the plug are connected. The connection is more reliable, which ensures that the inner wire of the plug will not easily fall off the copper sheet of the plug under the action of external force, which improves the overall safety of the device.
