A plug 5 is fixedly inserted in the middle of the upper end of the card seat 4. Pins 6 are arranged at the upper end of the plug 5. The pins 6 can be two rectangular plate structures of the standard pins. The pins 6 are inserted into the upper end of the plug 5. A reinforcing part is arranged at the position where the pins 6 are inserted into the plug 5 to ensure the stable connection of the pins 6. A connector 12 is arranged at the lower end of the pins 6. The connector 12 is electrically connected to the conductive plate 11 through a wire, as Figure 13As shown, the pin 6 can be the two-cylinder structure of the European standard pin, such as Figure 14 As shown, the pin 6 is also the three-long-strip-plate structure of the British standard pin. The connectors 12 at the lower ends of the two parallel pins 6 on one side are electrically connected to the conductive plate 11 through wires. The distribution of the pins 6 is not limited to the above situation, and it can also be the pin structures of various national and regional standards such as those of the United States, Japan, and South Korea.

[0059] Such as Figures 4 - 6 As shown, a clamping mechanism 7 is provided between the card seat 4 and the ring seat 3.
