Anti-displacement cylinder wearing ring

The utility model provides an air cylinder wear-resisting ring capable of preventing displacement. The device comprises a guide column, a wear-resistant ring, a piston, a first connecting column, a steel wire rope, a second connecting column, a connecting groove, an iron sheet, a cushion, a magnetic sheet and a limiting column, pistons are assembled on the annular side surfaces of the guide columns; a wear-resistant ring is mounted on the annular side of the piston; a first connecting column is fixed on the outer surface of the wearing ring; a second connecting column is fixed on the lower side of the first connecting column; connecting grooves are formed in the annular side surfaces of the first connecting column and the second connecting column; steel wire ropes are connected to annularside surfaces of the connecting grooves; iron sheets are mounted on the inner walls of the wear-resisting rings; by means of the design, the problem that an original air cylinder wear-resisting ring is poor in anti-displaceme
