A cantilever type large-stroke precise push-pull device comprises a push-pull arm mechanism, a synchronous rope row mechanism, a hydraulic power system, a hydraulic cylinder relay type supporting device and a push-pull arm supporting device. The push-pull arm mechanism is composed of a fixed arm and a multi-stage movable arm, and the multi-stage movable arm is sleeved with the fixed arm. The hydraulic power system comprises a hydraulic cylinder and a hydraulic pump station, the top end of a piston rod of the hydraulic cylinder is hinged to the rear end of the fixed arm, a cylinder barrel of the hydraulic cylinder horizontally extends into the multi-stage movable arm, and the piston rod of the hydraulic cylinder is flush with the axis of the push-pull arm mechanism; the hydraulic cylinder relay type supporting device comprises a supporting table and a supporting wheel, and the supporting table and the supporting wheel are arranged in different movable arms of the multiple stages of movable arms respectively. The push-pull arm supporting device is arranged at the front end of the multi-stage movable arm; the device further comprises a stroke monitoring mechanism, a push-pull force monitoring mechanism and a cable synchronizing mechanism. The push-pull device is small in section size, capable of stretching into a long and narrow closed box to conduct corresponding push-pull operation, complete in function, reliable in performance and easy to implement and popularize.
