1. A rotatable extension plugboard, comprising a plugboard seat (1) and a plug assembly (2), wherein a boss (301) with an inner cavity is formed at a backplane (3) of the plugboard seat (1), the plug assembly (2) is mounted on the boss (301) through a rotating seat (202) provided on the plug assembly, a limiting tooth (212) is formed on an upper surface of the rotating seat (202) and a limiting groove (321) is formed on an inner circumferential edge of a protruding edge (311) on an inner wall of the boss (301), and the plug assembly (2) is rotatable in a limiting manner relative to the plugboard seat (1) through engagement between the limiting tooth (212) and the limiting groove (321);
wherein the limiting groove (321) is in a semi-arc shape to restrict the plug assembly (2) to only rotate within a range of 0° to 180° relative to the plugboard seat (1);
the plug assembly (2) is provided with a positioning plate (203) mutually fastened with the rotating seat (202), the protruding edge (311) located between the positioning plate (203) and the rotating seat (202), the positioning plate (203) and the protruding edge (311) together form a positioning structure capable of fastening the plug assembly (2), the positioning structure comprises several tooth positions (331) formed at a surface of the protruding edge (311) facing the positioning plate (203), and an opposite surface of the positioning plate (203) forms several positioning bumps (213) corresponding to the tooth positions (331);
wherein the entire positioning plate (203) is made of plastic, the positioning bumps (213) can be positioned and matched with different tooth positions (331) through deformation when artificially twisted, so that the rotated plug assembly (2) is relatively fastened with the plugboard seat (1).
