[0021] Working principle:

[0022] The first circuit wiring mode is that an end of a first wire is sleeved between the two nuts 3 on each screw rod 1, and the two first wires are conducted through the screw rod 1 and the first conductive body 12.

[0023] The second circuit wiring mode is that an end of a second wire is sleeved between the conductive part 5 and the first insulation sleeve 4 on each screw rod 1, and the two second wires are conducted through the conductive part 5, the conductive protrusion 11 and the second conductive body 13.

[0024] The first conductive body 12 is rotatably sleeved with the left screw rod 1, the insulation handle 14 is manually toggled, the first conductive body 12 is driven to rotate around the left screw rod 1, and the second conductive body 13 is further driven to rotate.Figure 6 , Figure 7 As shown, when the notch at the right end of the first conductor 12 disengages from the screw 1 on the right side, both the first and second wires are no longer connected.

[0025] The first insulating sleeve 4 and the second insulating sleeve 6 can provide support and have a certain height, and can also improve the electrical performance of the product (increasing the creepage distance of the two circuits).
