The application provides a Christmas tree built-in lifting device comprising a base, a lifting device fixed on the base. The lifting device comprises an outer tube, an inner tube, a motor, a chain, a coupling, a transmission gear, a chain fixing plate, a driven gear. The Christmas tree lifting device is configured as a built-in chain lifting device, and the motor drives the chain to rotate and then drives the inner tube fixed on the chain to realize lifting. The lifting of this solution is faster and with less noise. The lower end of the built-in chain lifting device is configured as a contact to take power, and the upper end is configured as a contact to transmit power. The multi-stage lifting device can be stacked repeatedly as required, thereby making it more convenient for users to use as required, and the multi-stage lifting device is more convenient for transportation.
