One end of the socket structure 1 is used for plugging or matching with the plug structure, and the other end is a connecting wire 20. Moreover, the forked electrodes are spaced apart from each other in the base 10, and the positions of the electrodes are set according to the national standard of power connectors. The guide plate 11 is movably disposed in the base 10, and the guide plate 11 has three openings 31, 32, 33 corresponding to the three forked electrodes, respectively, and the forked portion of each forked electrode is inserted into the corresponding opening of the guide plate 2. Specifically, for example, a first forked electrode is inserted into the opening 31, a second forked electrode is inserted into the opening 32, and a third forked electrode is inserted into the opening 33.
In addition, the handle 12 has a cam end 121 and an operation end 122, the cam end 121 is coupled to the base 10, and the operation end 122 is exposed out of the base 10. For example, the cam end 121 of the handle 12 is rotatably connected to the base 10 through the rotating shaft 13, the elastic element is disposed in the base 10 and abuts between the bottom of the base 10 and the guide plate 11, and the guide plate 11 is interposed between the cam end 121 of the handle 12 and the elastic element. The elastic element is a structure such as a return spring or a spring plate and the like, and provides return elastic force.
Moreover, since there are three forked electrodes in the present invention, in order to ensure the force uniformity of the guide plate, it is preferable that the elastic element includes a first forked electrode 41 and a second forked electrode 42, and the first forked electrode 21, the second forked electrode 22 and the third forked electrode 23 are sequentially disposed in the base, so that the first forked electrode 41 is located between the first forked electrode 21 and the second forked electrode 22, and the second forked electrode 42 is located between the second forked electrode 22 and the third forked electrode 23.

When the operating end 122 of the handle 12 is not subjected to an external force, the elastic element pushes the guide plate 11 towards a predetermined direction due to the elastic force, the opening of the guide plate 11 limits the fork-shaped portion of the corresponding fork-shaped electrode, so that the fork-shaped portion of each fork-shaped electrode is in a pressing and clamping state; when the operation end 122 of the handle 12 is rotated by an external force, the cam end 121 of the handle 12 pushes the guide plate 11 in a direction opposite to the predetermined direction, and the opening of the guide plate 11 is separated from the fork-shaped portion of the corresponding fork-shaped electrode, so that the fork-shaped portion of each fork-shaped electrode is restored to the spread state. In the present invention, the predetermined direction is a direction in which the elastic member faces the guide plate 11. That is, an external force is applied to the operation end 122 of the handle 12, the operation end 122 of the handle 12 is rotated by the external force, the cam end 121 of the handle 12 pushes the guide plate 11 in the opposite direction of the predetermined direction, the opening of the guide plate 11 is separated from the fork-shaped portion of the corresponding fork-shaped electrode, so that the fork-shaped portion of each fork-shaped electrode is in the open state, i.e., the corresponding fork-shaped portion of the fork-shaped electrode is not in contact with the opening, and the plug structure can be easily inserted into the socket structure without resistance. Releasing the external force, the operation end 122 of the handle 12 will rotate and return to the natural state due to the disappearance of the external force, at this time, the elastic element will push the guide plate 11 towards the predetermined direction due to the elastic force, the opening of the guide plate 11 is limited to correspond to the forked portion of the forked electrode, so that the forked portion of each forked electrode is in a pressing and clamping state, and at this time, the forked electrode of the socket structure 1 contacts with the plug contact end of the plug structure to establish the electrical connection. Similarly, when the plug structure needs to be removed, only external force needs to be provided for the operation end 122 of the handle 12, the operation end 122 of the handle 12 can rotate due to the external force, at this time, the cam end 121 of the handle 12 pushes the guide plate 11 in the reverse direction of the predetermined direction, the opening of the guide plate 11 is separated from the fork-shaped part corresponding to the fork-shaped electrode, so that the fork-shaped part of each fork-shaped electrode is in a developing state, namely, the fork-shaped part of the corresponding fork-shaped electrode is not in contact with the opening at this time, and then the plug structure can be easily removed without resistance.
