Abstract: An impact protecting modular block includes an anchoring portion adapted to be secured on a corner of an industrial computer, and an abutment portion integrally formed with and extending transverse to the anchoring portion and adapted to abut against a surrounding wall of the industrial computer. The anchoring portion of a first modular block can be stacked upon and can be secured on the anchoring portion of a second modular block so as to permit the abutment portion of the first modular block to abut against the abutment portion of the second modular block, thereby raising rear corners of the base body relative to front corners of the base body of the industrial computer for convenient operation.
