Rotation member prevented from being entangled, and jigsaw puzzle table

A rotation member prevented from being entangled, comprising:

• a base and a rotation element, wherein the rotation element is rotatably mounted on the base;
• a first cable assembly, a second cable assembly, and an electrical conductive assembly, wherein the first cable assembly is mounted on the rotation element to be connected to an electric device;
• the second cable assembly is mounted on the base to be connected to an external power supply source;
• wherein the electrical conductive assembly comprises an electrical conductive terminal and an electrical conductive member electrically connected to the electrical conductive terminal;
• when the rotation element rotates relative to the base, the electrical conductive terminal is configured to perform a circular motion on the electrical conductive member, and a center of the circular motion coincides with a rotation center of the rotation element;
• the electrical conductive terminal is electrically connected to one of the first cable assembly and the second cable assembly, and the electrical conductive member is electrically connected to the other one of the first cable assembly and the second cable assembly;
• wherein the rotation element defines a first wire slot, a slot bottom facing the base defines a first through hole;
• the electrical conductive assembly is at least partially received in the first wire slot, and the electrical conductive terminal passes through the first through hole to be exposed out of the rotation element to be electrically connected to the electrical conductive member.
