Description

Technical Field

[0001] The utility model relates to the technical field of shooting equipment, in particular to a rotating module and a pan head. Background Art

[0002] With the continuous development of gimbals, users' shooting skills for gimbals have gradually improved. The gimbal includes multiple motors, and the rotation and control of each motor requires electrical connection through wires.
