A testing turntable comprises a base, a hollow support rod vertically fixed on the base, an abutment mounted on the support rod and capable of rotating around the support rod, and a plurality of conductive components arranged on the support rod, wherein a plurality of power sockets are arranged on the abutment; each conductive component comprises an accommodation tank arranged and fixed on the support rod in a sleeving manner, a plurality of lead wires and a wire; conductive liquid is accommodated in the accommodation tanks; a top cover of each accommodation tank is provided with a cover body capable of rotating relative to the support rod; the wires are accommodated in the support rod; one end of each wire is connected with an external power supply; the other end of each wire is inserted into the conductive liquid; one end of each lead wire is inserted into the conductive liquid; and the other ends of the lead wires are connected with the power sockets. The conductive liquid in the accommodation tanks of the testing turntable is connected with a mains supply via the conductive components; the lead wires rotate with the abutment; the wires are not required to be electrically connected with the mains supply directly; and the situation of a power supply short circuit due to the twisted wires is avoided.
