Deflection-preventing multi-stage oil cylinder forge piece

The utility model relates to the technical field of oil cylinders, in particular to an anti-deflection multistage oil cylinder forge piece. According to the technical scheme, the device comprises a base, through cooperation of a first-stage buffer spring rod and a first-stage lifting cavity and cooperation of a second-stage buffer spring rod and a second-stage lifting cavity, the multi-stage oil cylinder can be effectively prevented from deflecting, when the multi-stage oil cylinder moves through a laser inductor and a laser transmitter, once the multi-stage oil cylinder deflects, the laser inductor induces the deflection, and then the multi-stage oil cylinder is stopped from moving. A driving motor is started to drive a driving gear to rotate, then a driven gear and a lead screw are driven to rotate at the same time, a lead screw nut sleeve and a supporting frame are made to move towards the inner side, and therefore the position fixity of the multi-stage oil cylinder in the extending and retracting state is
