Specifically, the socket end of the rotating rod 1 has an opening 11, and the outer side wall of the opening 11 has a groove 12.

As shown in fig. 1 and 2, the connecting member 3 has a sleeve-connecting end sleeved on the rotating shaft 21, and the sleeve-connecting end of the rotating rod 1 is sleeved on the periphery of the sleeve-connecting end of the connecting member 3. Meanwhile, the connecting member 3 is electrically connected to the rotating lever 3 through the rotating shaft 21. Specifically, the sleeve end of the connecting part 3 is inserted into the opening 11 of the rotating rod 1, and the rotating rod 1 and the connecting part 3 are movably sleeved on the rotating shaft 21.

As shown in fig. 1 and 2, an insulating shell 31 is coated on the outer surface of the coupling end of the connector 3. Through setting up insulating casing 31, it can prevent to rotate electrically conductive pass connecting piece 3 with dwang 1 directly switches on. In addition, the insulating shell 31 can prevent the positive and negative electrode circuits from being communicated with each other, thereby avoiding the exposure of wires or conductive structures and improving the sealing property and the aesthetic property.

With continued reference to fig. 1 and fig. 2, the insulation shell 31 includes a first insulation shell 311 and a second insulation shell 312 sleeved on the rotating shaft 21. The first insulating shell 311 and the second insulating shell 312 cooperate with each other to form a receiving cavity, and the receiving cavity is used for receiving the sleeve end of the connecting element 3.

As shown in fig. 1 and 2, a conductive sheet 32 is half-coated inside the insulating case 31. That is, at least a portion of the conductive sheet 32 passes through the insulating case 31 to be connected to an external electrode. In this embodiment, one end of the conductive sheet 32 is covered in the second insulating case 312, and the other end thereof penetrates through the second insulating case 312.

As shown in fig. 1 and 2, the rotation shaft 21 penetrates through the opening 11, the sleeving end of the connecting member 3, the spring plate 22 and the fixing member 23, one end of the rotation shaft 21 is movably abutted against the side wall of the opening 11, and the other end of the rotation shaft 21 is movably riveted with the fixing member 23 by a screw 24.

Wherein, pivot 21 respectively with dwang 1 and connecting piece 3 electric connection is used for realizing dwang 1 with connecting piece 3 switches on.

As shown in fig. 1 and 2, the fixing member 23 is located in the groove 12, and the fixing member 23 is rotatably connected to the rotating shaft 21 by a screw 24. The fixing piece 23 can press the elastic sheet 22 along the axial direction of the rotating shaft 21, so that the elastic sheet 22 is prevented from moving back and forth along the rotating shaft 21 in the rotating process, and the stability of the conductive connection between the elastic sheet 22 and the conductive sheet 32 is influenced. In addition, the fixing member 23 is made of a plastic material having an insulating effect, and can perform an insulating protection effect on the conducting circuit of the elastic sheet 22.
