A fixed socket 13 is inserted at the front end of the connection slot 3. A connection plug 12 is connected to the front end of the fixed socket 13. A connection rod 14 is connected to the rear end of the fixed socket 13.

[0028] The connecting slot 3 is located at the front end of the adapter body 1 and contacts the power connection slot 4 and power connection lever 5 at the front end of the circuit board 8 inside the adapter body 1. The fixed socket 13 carries the connecting rod 14 and engages with the connecting slot 3. The connecting rod 14 is inserted into the power connection slot 4 at the rear end of the connecting slot 3. The connecting plug 12 is fixed to the front end of the adapter body 1 through the fixed socket 13.

[0029] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, by setting a replaceable plug structure, when in use, the connector plug 12 is inserted into the connector slot 3 at the front of the adapter body 1 through the fixed socket 13 at the rear end and the connector rod 14. The connector rod 14 at the rear end of the fixed socket 13 is inserted into the power connection slot 4 inside the circuit board 8, so that the fixed socket 13 is engaged with the inside of the connector slot 3. The rear end of the fixed socket 13 contacts the power connection switch 5, fixing the connector plug 12 to the front end of the adapter body 1. This makes it easy to replace the connector plug 12 for different regions as needed, thus realizing the replaceable plug function.
