[0066] The connection socket 212 is connected to the control chip 15 by means of wires so as to be powered when connected to a power source.

[0067] Among them, the flip component 3 includes two groups of second connecting components 31, one group of second connecting components 31 is used to connect positive electricity, and the other group of second connecting components 31 is used to connect negative electricity, so that when two power supply sockets 1 are connected, the second connecting component 31 for connecting positive electricity on the second connecting side 12 of one power supply socket 1 is connected to the second connecting component 31 for connecting positive electricity on the fourth connecting side 14 of the other power supply socket 1, and the second connecting component 31 for connecting negative electricity on the second connecting side 12 of one power supply socket 1 is connected to the second connecting component 31 for connecting negative electricity on the fourth connecting side 14 of the other power supply socket 1, so as to realize conduction between the two power supply sockets 1.

[0068] Specifically, the second connecting component 31 includes a second guide member 311, a flip seat 312, a second fixing member 313, and an elastic conductive sheet 314; the second connecting side 12 and the fourth connecting side 14 are both provided with a second track 32 and a flip cavity 33, the track direction of the second track 32 is along the left-right direction so that the second connecting side 12 and the fourth connecting side 14 face the same direction, the second track 32 and the flip cavity 33 are connected, and the flip cavity 33 is provided on the side of the second track 32 away from the other group of flip components 3 The flip seat 312 is located in the flip cavity 33, and the front and rear ends of the flip seat 312 are inserted into the power supply seat 1, and the flip seat 312 is flipped and set in the flip cavity 33. The elastic conductive piece 314 is fixed to the power supply seat 1 by a snap-on method. The front and rear ends of the flip seat 312 are located in the power supply seat 1 and are provided with abutment discs 3121. The end surface of the abutment disc 3121 is provided with a conductive portion 3122. The elastic conductive piece 314 is provided with an elastic foot 3141, and the elastic foot 3141 is in a deformed state and The second guide member 311 is abutted against the end surface of the contact disc 3121, and the elastic foot 3141 is located on the rotation track of the conductive part 3122, so that the conductive part 3122 rotates with the flip seat 312 to contact the elastic foot 3141 or move away from the elastic foot 3141; the second fixing member 313 detachably fixes and connects the second conductive member 311 and the flip seat 312, and connects the second conductive member 311 and the conductive part 3122; wherein, when the length direction of the second conductive member 311 is along the track direction of the second track 32, the conductive part 3122 is The through portion 3122 and the elastic foot 3141 are in contact and conduction, and when the length direction of the second conductive member 311 is not parallel to the track direction of the second track 32, the conductive portion 3122 and the elastic foot 3141 are in non-contact; wherein, the side of the flip cavity 33 away from the second track 32 is open to allow the second conductive member 311 to extend out of the flip cavity 33; wherein the second track 32 is for the second conductive member 311 to slide into, and the second conductive member 311 can slide out of the second track 32 to flip along with the flip seat 312.

The second conductive member 311 of the fourth connection side 14 of the seat 1 is disassembled to vacate the flip cavity 33 for the extended second conductive member 311 to be inserted, and then the second fixing members 313 on the two power supply seats 1 are respectively connected to the second conductive member 311 and the two flip seats 312 to fix and conduct the second connection side 12 of one power supply seat 1 and the fourth connection side 14 of the other power supply seat 1. 3. When it is necessary to use the flip assembly 3 to connect the two power supply seats 1 in a V-shaped state, the second conductive member 311 on the second connection side 12 of one power supply seat 1 passes through the flip cavity 33. The opening extends out of the flip cavity 33, and the second conductor 311 and the flip seat 312 are flipped downward synchronously, and then the second conductor 311 of the fourth connection side 14 of the other power supply seat 1 is removed to vacate the flip cavity 33, and the flip seat 312 is flipped downward to allow the extended second conductor 311 to be inserted into the position, and then the second fixing members 313 on the two power supply seats 1 are respectively connected to the second conductor 311 and the two flip seats 312 to fix the second connection side 12 of one power supply seat 1 and the fourth connection side 14 of the other power supply seat 1, but the circuit is flipped. There is no conduction at component 3. 4. When the flip component 3 needs to be used as a support foot, the second conductor 311 on the second connection side 12 or the fourth connection side 14 of the power supply seat 1 extends out of the flip cavity 33 through the opening of the flip cavity 33, and the second conductor 311 and the flip seat 312 are flipped upward simultaneously, and then the second conductor 311 and the flip seat 312 are fixedly connected by the second fixing member 313. At this time, the conductive part 3122 and the elastic foot 3141 are misaligned, so that the second conductor 311 is not energized, so that the power supply seat 1 can be tilted by supporting it on the desktop through the second conductor 311.

[0070] The lower end of the second track 32 is open, and a magnet 315 is disposed in the upper surface of the second track 32, so that when the second guide member 311 is located in the second track 32, it is restricted by the upper surface of the second track 32 and cannot flip upward, and the magnet 315 adsorbs the second guide member 311 to ensure that the second guide member 311 is stable in the second track 32.

The first positioning portion 3125 and the second positioning portion 3126 strongly position the mating tooth portion 34 on the trajectory of the mating tooth portion 34, so that the mating tooth portion 34 rotates to counteract the first positioning portion 3125 or the second positioning portion 3126 and cannot continue to rotate. When the mating tooth portion 34 rotates to the first positioning portion 3125, it is the position where the flip assembly 3 is used as a support foot, so that the flip assembly 3 is more stably supported, and when the mating tooth portion 34 rotates to the second positioning portion 3126, it is the position where the flip assembly 3 is used to connect the two power supply seats 1 in a V shape, so that the flip assembly 3 is more stably connected.
