Stride across block device

The utility model discloses a stride across block device relates to electric wire netting construction technical field, the problem of solution be provide that a fail safe nature height, technique are feasible, the stride across block device of construction convenience, economical rationality. The main technical scheme who adopts does: first block system and with the first mirror symmetry's of block system second block system, first block system and second block system are at a distance of the predetermined distance, first block system includes: the guide rail promotes the structure setting on crossing structure, the guide rail promotes the structure and can remove along crossing structure, the first end of block structure rotates with guide rail promotion structure to be connected for remove along crossing structure under the drive of guide rail promotion structure, it connects respectively in the second end of crossing structure and block structure to receive and release the structure for when the block str
