Does anyone know what kind of camera stand this is, what brand it is and where I can buy it. Thanks

Modified light stand: tripod + long central axis + cross arm (because there is no pan/tilt, the shooting angle cannot be adjusted, and the central axis is too long, making it unstable as a tripod.) The top thread of the horizontal arm can be connected to the camera When shooting from above, with a sandbag on the other end, there is no problem with stability. I couldn't find the exact same one. There are many "light stands" with similar functions on Taobao.
