The present invention provides a combined power socket for artificial trees. The combined power socket includes a first socket and a second socket which are capable of supplying control signals to light strings on the artificial trees in addition to power supply, thus can realize the intelligent control of light strings. Furthermore, the first socket and a second socket can be connected in two directions without considering the positive and negative poles of the power supply. The product assembly is simpler and more convenient.
