Abstract: A structure for installing a split style diamond disk, having a fixing plate, a spring press plate, a connection plate, and a plurality of fast installation grinding blocks. The spring press plate is fixed to the fixing plate through screws with springs sleeved thereon, and the connection plate runs through the spring press plate and connects with the fixing plate by screws. The fixing plate has a plurality of L-shaped grooves provided therein, through which the fast installation grinding blocks are mounted on the fixing plate. The fast installation structure is mounted on an equipment shaft through the connection plate. The structure improves the capacity utilization and work efficiency of the grinding blocks.
