Plug adaptor

A power adapter, comprising:

• a housing;
• a rotatable plug, rotatably connected to the housing via a rotating portion and being capable of switching between a retracted state and an in-use state;
• two slidable plugs, arranged on the housing and being capable of sliding vertically;
• wherein each slidable plug comprises:
• a slidable plug body;
• and
• a drive member, partially extending outside the housing;
• an interlocking mechanism, comprising:
• a limiting assembly, horizontally slidably arranged on the housing and comprising a first limiting portion and a second limiting portion;
• a locking assembly, comprising a locking portion that is horizontally slidable;
• and
• a locking member, in a transmission connection with the rotating portion;
• an electrical connection member, fixedly arranged in the housing;
• and
• a protective module, arranged in the housing and coupled to the electrical connection member;
• wherein:
• in a case where the rotatable plug is switched to the in-use state, the rotating portion drives the first limiting portion to move horizontally, causing the second limiting portion to block the drive member of one of the two slidable plugs, while the locking portion blocks the drive member of the other of the two slidable plugs;
• in a case where one of the two slidable plugs is switched to the in-use state, the drive member of the one of the two slidable plugs drives the locking portion to move horizontally, causing the locking portion to block the drive member of the other of the two slidable plugs;
• the protective module is configured to, in a case where one of the rotatable plug and the two slidable plugs is in the in-use state, cut off an electrical connection between others of the rotatable plug and the two slidable plugs and the electrical connection member.
