The present invention relates to a binding hole for guiding rotation of a camera by being combined with the camera and, more specifically, to a binding hole of a ball head having a bifacial sliding rotation structure capable of: simplifying the structure and assembly process of the binding hole, reducing the assembly time, accordingly improving productivity by integrating a ball head or a quick shoe and a rotating housing, and combining a fixing plate and a rotating drum using male and female screws while placing a guide ring therebetween; reducing frictional force and enabling smooth and stable horizontal rotation by, in particular, inserting a sliding member to the top and the bottom surface of the guide ring; and enhancing the outward appearance as the structure is simplified and a combining unit is not exposed to the outside in a combination process. |
