Referring to fig. 11, on the basis of the seventh embodiment, the socket of the fourteenth embodiment further includes a ground rotating base 215, and the rotating base 2 can be used in cooperation with the ground rotating base 215. Rotating base 2 and utmost point rotating base 215 intermeshing, specifically, be equipped with local cylinder straight-tooth structure on the rotating base 2, utmost point rotating base 215 is equipped with the straight-tooth structure of bar, both intermeshing. Because the earth pole of three flat base pins of Australian style/chinese style is participated in and is participated in longer than anodal base pin and negative pole and participate in, when the plug inserts, earth pole rotating base 215 receives the pressing force that the earth pole was participated in earlier, and earth pole rotating base 215 will incline earlier and move and drive rotating base 2 and rotate. The moving distance of the safety door is consistent with the arc length of the local cylindrical straight tooth structure of the rotating base 2 rotating in the reference circle, and the corresponding angle of the arc length is 30 degrees.

Example fifteen

Referring to fig. 10, the positive electrode rotating base 21 and the negative electrode rotating base 22 of the fifteenth embodiment are provided with a movable space 214 for connecting the power supply line to the positive electrode holder 31 and the negative electrode holder 32. When the positive electrode holder 31 and the negative electrode holder 32 are respectively mounted on the positive electrode rotating base 21 and the negative electrode rotating base 22, the movable space 214 enables the power line to be connected with the positive electrode holder 31 and the negative electrode holder 32, thereby facilitating reasonable layout of the power line without connecting with the positive electrode holder 31 and the negative electrode holder 32 through complicated winding.

Example sixteen

Referring to fig. 1, the bottom surface of the ground pole seat 4 of the sixteen embodiment is provided with a connecting elastic sheet 46, and the ground pole seat 4 is connected with the socket copper pin 5 through the connecting elastic sheet 46.

Referring to fig. 7, the ground pole holder 4 is further extended with a fixing portion 47, and optionally, the fixing portion 47 is extended along the bottom of the ground pole holder 4. Referring to fig. 12, the mounting seat 6 is provided with a fixing seat 66 engaged with the fixing portion 47, and the fixing seat 66 is provided with a fixing groove, so that the ground pole seat 4 is fixed on the mounting seat 6 by the engagement of the fixing groove of the fixing portion 47 and the fixing seat 66.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
