In the initial state, the two moving members 122 are located at one end of the first sliding groove 1243 close to the center of the safety cover 124 due to the action of the spring 123, that is, the distance between the two moving members 122 is shortest; at this time, the partition 1211 is located between the conductive contact 1131 and the contact plate 1121, and is separated from the contact plate 1121, that is, the conductive sheet 113 is not conducted.

When a conductor such as a pin or other conductive objects is inserted into the insertion hole 141, the conductor pushes the moving member 122 below the insertion hole 141 to move in a direction away from the center of the safety cover 124, the movement of the pushed moving member 122 causes the spring 123 to be elongated, so that the spring tension applied to the un-pushed moving member 122 is increased, and the un-pulled moving member 122 is tightly abutted against the side wall of the first sliding groove 1243 at the end close to the center of the safety cover 124, so that the conductive contact 1131 at the side of the inserted conductor is always separated from the contact plate 1121 to be powered off, thereby avoiding the conductor from being conductive and causing electric shock hazard; at the same time, the partition 1211 positioned on the other side of the conductor moves under the action of the conductor to make the contact 1131 on the side contact the contact plate 1121 for conduction; when a user inserts two-pin plugs into the insertion holes 141 at the same time, the pin on one side makes the conductive contact 1131 of the pin on the other side conduct with the contact plate 1121, that is, the pin on one side makes the pin on the other side conduct, and since the two moving members 122, the conductive sheet 113 and the partition member 121 are arranged in a central symmetry manner, when the two pins are inserted into the sockets at the same time, the two pins can both conduct, so that the electrical appliances connected with the plugs can be used normally.

When the user pulls out the plug from the socket after the power consumption is completed, the spring 123 contracts and simultaneously drives the two moving rods 122 to return to the idle state, so that the partition 1211 separates the conductive contact 1131 from the contact plate 1121 again, and the conductive sheet 113 is disconnected.

According to the invention, by arranging the moving part 122 and the partition plate part 121, the purpose that a conductor is inserted into one of the jacks 141 to conduct the conducting plate 113 on the other side is achieved, when only one jack 141 is inserted into the conductor, the corresponding conductor plate 113 is not conducted with the conductor plate 113 on the other side, so that an electric shock accident is avoided when a single conductor is inserted, and when conductors are inserted into two jacks 141, two conductor plates 131 are conducted simultaneously, so that the function of normal electricity utilization is achieved; the rotary connecting disc 11 is rotatably connected with the electrode mounting seat 13, and is always communicated with the electrode mounting seat 13 in the rotating process of the rotary connecting disc 11, so that the purpose of rotating the electrifying assembly 1 is realized; the insulating plate 114 is arranged, so that the conductor cannot be directly contacted with the conductor 112 when being inserted into the jack 141, and electric shock is prevented; according to the invention, the spring 123 is fixedly connected between the two moving parts 122, so that after the plug is pulled out, the moving parts 122 drive the partition plate member 121 to move, so that the partition 1211 moves again between the conductive contact 1131 and the contact plate 1121 in an insulated manner; when a conductor is inserted into only one of the insertion holes 141, the moving element 122 makes the moving element 122 not pulled tightly abut against the side wall of the first sliding groove 1243 near the end of the center of the safety cover 124 under the action of the spring 123, so as to prevent the partition 1211 on the side of the inserted conductor corresponding to the moving element 122 from moving and causing the conductive contact 1131 on the side of the moving element 122 to be conducted with the contact plate 1121 to get an electric shock; through setting up two when making the plug insert in the socket need not rotate the plug at the intermediate process, make the plug disect insertion in the socket can, easy and simple to handle.
