[0003] The existing clamping jaws also have a rotation function. The existing clamping jaws mainly use a conductive slip ring assembly. The conductive slip ring assembly is a precision power transmission device that uses the sliding contact, electrostatic coupling or electromagnetic coupling of the slip ring body to transmit electrical signals and electrical energy between the rotating part of the fixed seat frame and the rolling or sliding part. It is widely used in applications that require unlimited, continuous or intermittent 360-degree rotation.
