The utility model relates to a cylinder rod connecting device for the swaying hydraulic cylinder of a working roll. One side of the cylinder rod of the hydraulic cylinder connected with a fixed block at the work side is opened with a circle of grooves; two semi-circle tilting fillets are blocked in the grooves; and the tilting fillets are embedded in the fixed block at the work side. As the screw thread and nut connection is changed into the groove and tilting fillet connection, the problems that the nut is released and replaced and the electrical element is damaged are thoroughly eliminated, and the number of connection components, the accumulating clearance error and the vibration of the cylinder rod are reduced relatively, thereby prolonging the service life of the hydraulic cylinder, shortening the replacing time, reducing the labor intensity and ensuring the normal swaying of the working roll, so as to improve the output of a rolling mill and the surface quality of a steel plate.
