The socket unit 12 is disposed in the receiving space 22 of the casing 18 and has a plurality of socket terminals 26 corresponding to the socket openings 24. The cover 20 is disposed at the opening of the casing 18 to enclose the accommodating space 22. A ground terminal groove 28 is formed on the outer side surface of the cover 20, a first plug terminal groove 30 is formed on each of both sides of the ground terminal groove 28, and a second plug terminal groove 32 is formed on each of the outer sides of the first plug terminal grooves 30. The lid member 20 is provided with a notch 34 at each side along the extending direction of the ground terminal groove 28. And a track 36 is respectively provided on two opposite side walls of the notch 34. A ground terminal 38 corresponding to the british plug standard is pivotally provided in the ground terminal groove 28. When stowed, the ground terminal 38 is flipped inward into the ground terminal slot 28; in use, the ground terminal 38 is flipped outwardly to an upright position.

The first plug unit 14 includes: a first swing base 40, two first plug terminals 42 and a first driving member 44. The first rocking base 40 is a U-shaped member having a first main section 46 and two first extending sections 48 located at two ends of the first main section 46 and extending along a direction perpendicular to the first main section 46. The first extensions 48 each have an outwardly extending first shaft portion 50, and the first shaft portions 50 extend along a first axial direction L1. The first main section 46 has a first driving portion 52 at the center thereof, and first fixing portions 54 at both sides of the first driving portion 52. The first driving portion 52 is not located in the first axial direction L1, and is spaced apart from the first axial direction L1 by a predetermined distance. In this embodiment, the two first fixing portions 54 are two screw holes disposed on the first rocking base 40, and two locking members 56 pass through the first plug terminal 42 and then are locked into the screw holes, so that the two first plug terminals 42 are fixed to the first fixing portions 54; in the present embodiment, the two fasteners 56 are bolts.

Referring to fig. 1 and 4, fig. 4 is a cross-sectional view of the universal adapter structure. In an initial state, the first driving member 44 is not pressed, and the first plug terminals 42 are located at the storage positions received in the first plug terminal slots 30. Next, referring to fig. 5, when the first driving member 44 is pressed to move downward, the first abutting portion 58 presses against the first driving portion 52 of the first rocking base 40 to apply a torque to the first rocking base 40 to pivot the first rocking base 40, so that the outer ends of the two first plug terminals 42 pivot in a direction away from the housing 10, leave the two first plug terminal slots 30, and rotate to an upright position. In this embodiment, the first driving member 44 is pressed to rotate the first plug terminals 42 outward by a predetermined angle, at which time the outer ends of the first plug terminals 42 are separated from the first plug terminal slots 30, and then the user can move the first plug terminals 42 to the using position.

Referring to fig. 1 and 3 again, the second plug unit 16 includes: a second swing seat 62, two second plug terminals 64 and a second driving member 66. The second rocking base 62 is a U-shaped member having a second main section 68 and two second extending sections 70 located at two ends of the second main section 68 and extending along a direction perpendicular to the second main section 68. The second extension sections 70 each have an outwardly extending second shaft portion 72, and the second shaft portions 72 extend along a second axial direction L2. The second main section 68 has a second driving portion 74 at the center thereof, and second fixing portions 76 at both sides of the second driving portion 74. The second driving portion 74 is not located in the second axial direction L2, and is spaced apart from the second axial direction L2 by a predetermined distance. In this embodiment, the second fixing portions 76 are two tubes disposed on the second rocking base 62, and the second plug terminal 64 is fixed after being inserted into the two tubes.

The second rocking base 62 is disposed below the lid 20 at the opposite side of the first rocking base 40, and pivotally connected to the housing 18 with the second shaft portions 72, so that the second driving portion 74 is located at another gap 34, and the second plug terminals 64 respectively extend into the second plug terminal slots 32 through a hole of the lid 20. The two second plug terminals 64 are electrically connected to the two socket terminals 26, respectively. The second driving member 66 is an L-shaped plate disposed in the notch 34 of the housing 10. The second driving member 66 has a second abutting portion 77 on the inner side thereof, corresponding to the second driving portion 74 of the second rocking base 62, and a second guiding portion 78 on each of the two side end surfaces thereof. The second guiding portions 78 are combined with the two rails 36, so that the second driving member 66 is slidably disposed in the notch 34 of the housing 10 along the two rails 36.

As mentioned above, referring to fig. 1 and fig. 4 again, in an initial state, the second driving member 66 is not pressed, and the second plug terminal 64 is located at the storage position accommodated in the second plug terminal groove 32. Then, referring to fig. 6, when the second driving member 66 is pressed to move downward, the second abutting portion 77 presses against the second driving portion 74 of the second rocking base 62 to apply a torque to the second rocking base 62 to pivot the second rocking base 62, so that the outer ends of the second plug terminals 64 pivot away from the housing 10, leave the second plug terminal slots 32, and rotate to an upright position. In the embodiment, the second driving member 66 is pressed to rotate the second plug terminals 64 outward by a predetermined angle, at which time the outer ends of the second plug terminals 64 leave the second plug terminal slots 32, and then the user can continue to move the second plug terminals 64 to the using position. The pivoting direction of the second plug terminal 42 of the first plug unit 14 is opposite to the pivoting direction of the second plug terminal 64 of the second plug unit 16.

Next, please refer to fig. 7, which shows a first plug type of the universal adapter structure. In the present embodiment, the two first plug terminals 42 are two parallel plates, and form a plug suitable for taiwan, japan, usa, and the like.

Referring to fig. 3 and 8, fig. 8 shows a second plug type of the universal adapter structure. In this embodiment, the second plug unit 16 further has two auxiliary ribs 80, the two auxiliary ribs 80 respectively have a hole, and the two second shaft portions 72 of the second rocking base 62 respectively pass through the two holes, so that the two auxiliary ribs 80 are pivotally disposed on the second rocking base 62 and respectively located outside the two second plug terminals 64. The two auxiliary ribs 80 have a groove 82, respectively, facing the two second plug terminals 64, so that the two second plug terminals 64 have a portion located in the groove 82, causing the two auxiliary ribs 80 to move together with the two second plug terminals 64. In addition, each of the second plug terminals 64 has an auxiliary extension 65, which is fixed by being extended outward or retracted inward in a rotating manner. Referring to fig. 8, when the second plug terminals 64 and the auxiliary ribs 80 are rotated to the use position, a plug suitable for european areas is formed. When inserted into the ground's euro-scale socket 84, the two ribs fit into the two notches 86 in the euro-scale socket 84 to improve the stability of the adapter when coupled to the socket.

In summary, the present invention utilizes the design of the first driving member and the second driving member to change the existing operation mode of pulling out the plug terminal with fingers into pressing the driving member, so that the plug terminal is automatically turned over to the use state, thereby providing a more convenient operation mode; and the design of the auxiliary ribs is utilized, the stability of the universal adapter and the socket in combination is improved, and the problem that the firmness of the existing square adapter is insufficient when the square adapter is used in an European standard socket is solved.
