The high-precision hydraulic oil cylinder for the hoisting machinery comprises a hydraulic oil cylinder body, a buffering mechanism is arranged in the hydraulic oil cylinder body, and a protection assembly is arranged on the outer side of the hydraulic oil cylinder body. The hydraulic oil cylinder is simple in structure and reasonable in design, after oil enters the rod cavity in the hydraulic oil cylinder, the piston is pressed to drive the piston rod and the fixing block to move, and meanwhile hydraulic oil in the rodless cavity can be discharged through the oil cavity; the fixing block pushes the sliding block to slide and drives the baffle to close the auxiliary oil way, hydraulic oil in the rodless cavity is discharged out of the non-auxiliary oil way in the oil cavity, the baffle is driven by the buffering mechanism through the movement of the piston to close the auxiliary oil way, so that the number of discharging channels of the hydraulic oil is reduced, damping is increased, and when the piston gets
