a plurality of conductive pins formed on a first end of the second socket and configured to be received in the plurality of openings; and

a plurality of conductive wires in electrical connection with either the conductive contacts or the conductive pins, the conductive wires extending from outer sidewalls of either the first socket or the second socket;

wherein a first pair of the plurality of conductive wires extend between either the first socket or the second socket and an additional socket; and

wherein a second pair of the plurality of conductive wires extend from either the first socket or the second socket to a power plug.

2. The combined power socket according to claim 1 , wherein either the first socket or the second socket further comprises a plurality of blades extending outwardly and are configured to be arranged proximate to a ring body of the other of the first socket and the second socket such that the first and second sockets are detachably connected together.

3. The combined power socket according to claim 2 , wherein the first socket comprises:

an annular substrate;

an annular inner wall and an annular outer wall perpendicular to the substrate having an inner circumference and an outer circumference, respectively, and extending toward a first side of the substrate;

an annular cover plate connected to first ends of the inner wall and the outer wall to seal a space enclosed by the substrate, the inner wall, and the outer wall;

wherein the plurality of blades extend along the inner wall toward a second side of the substrate; and

a plurality of pillars extending from the substrate, wherein the plurality of openings are formed on the substrate radially at ends of the plurality of pillars; and

wherein the conductive contacts are electrically connected to the plurality of conductive wires extending from either the first socket or the second socket.

4. The combined power socket according to claim 3 , wherein the plurality of blades include four blades distributed uniformly and symmetrically about the substrate; and eight openings distributed uniformly and symmetrically about the substrate, wherein each opening of the eight openings is arranged adjacent to a side of one of the four blades, wherein four openings forming a group, and conductive contacts in the openings of the same group are electrically connected.

5. The combined power socket according to claim 4 , wherein the conductive contacts are metal tubes in a size matching an inner diameter of the openings and ends of the metal tubes in the openings of the same group facing the cover plate are electrically connected through an arc-shaped conductive tube, conductive rod, or conductive metal wire.

6. The combined power socket according to claim 3 , wherein the ring body connects the outer surfaces of the blades and the pillars, and a height of the ring body is the same as a height of the pillars but less than a height of the blades, such that the blades exceed the ring body and extend farther toward the second side of the substrate.

7. The combined power socket according to claim 6 , wherein the second socket comprises:

an annular second substrate;

an annular second inner wall and an annular second outer wall perpendicular to the substrate having an inner circumference and an outer circumference, respectively, and extending toward a first side of the second substrate;

an annular second cover plate connected to first ends of the second inner wall and the second outer wall to seal a space enclosed by the second substrate, the second inner wall, and the second outer wall;

a plurality of second blades extending along the second outer wall toward a second side of the second substrate; and

a plurality of second pillars extending along the outer wall toward the first side of the second substrate; and

wherein the plurality of conductive pins are insertable into the plurality of openings and being electrically connected to the plurality of conductive wires extending from the second socket.

8. The combined power socket according to claim 7 , wherein four second blades are distributed uniformly and symmetrically about the second substrate; four second pillars are distributed uniformly and symmetrically about the second substrate, and each second pillars is arranged adjacent to one of the second blades.

9. The combined power socket according to claim 8 , wherein the second side of the second substrate is further provided with a second ring body connecting outer surfaces of the second blades and the second pillars, and a height of the second ring body is the same as a height of the second pillars but less than a height of the second blades, such that the second blades exceed the second ring body and extend farther toward the second side of the second substrate.

10. The combined power socket according to claim 1 , wherein the first socket is sleeved on a lower-layer section of a trunk of the Christmas tree, the second socket is sleeved on an upper-layer section of the trunk of the Christmas tree, and the first socket and the second socket are electrically connected when the upper-layer section and the lower-layer section are connected together.
