At the same time, the second connector 1 moves rearward and pushes the pushing portion 31 to swing in a direction away from the first connector, so that the transmission member 3 is also restored to the original state together.

The second restoring member 5 is a spring, which is tensioned, and both ends of the spring are connected to the rail base 62 and the rear side of the second connector 1, respectively. The number of the second reset parts 5 is two, and the two second reset parts 5 are respectively connected to two ends of the second connector 1.

The second connector 1 comprises a mounting plate 11, a floating plate 12, at least one elastic member 13 and a plurality of poles 14, wherein the transmission part 3 is connected to the mounting plate 11, the floating plate 12 is movably mounted on the mounting plate 11 through the elastic member 13, and the plurality of poles 14 are mounted on the floating plate 12 and are used for being electrically connected with the first connector. The floating plate 12 is movably connected with the mounting plate 11 through the elastic piece 13, so that the electric connection between the second connector 1 and the first connector is more stable. Meanwhile, the second connector 1 is in contact with the first connector through the pole 14 to form electric connection, the mounting plate 11 is provided with a through hole, and the wiring end of the pole 14 penetrates through the through hole in the mounting plate 11, so that the pole 14 cannot be in contact with the mounting plate 11 when the second connector 1 is used, and the safety and stability of the electric connection device are further improved.

In the present embodiment, the number of the elastic members 13 is plural, and the plurality of elastic members 13 are respectively disposed at two ends along the length direction of the floating plate 12. Wherein, a plurality of elastic pieces 13 set up respectively in the left and right sides both ends of floating board 12, the upper and lower both ends of floating board 12 do not set up elastic piece 13 to effectively reduce electric connection device's overall height, the structure is compacter, and area occupied further reduces.
