What is the flower drum of the middle lock disc brake? Is it a quick-release disc brake hub?

Central locking is a patented technology of Shimano. Without his authorization, other companies cannot use it. To put it simply, his disc brake disc is locked and fixed on the hub by the external locking ring. Generally, the hub is fixed on the disc brake disc by six screws, which has nothing to do with quick disassembly or not!
