The invention discloses a jacking mechanism with a self-locking function and a using method thereof, and relates to the technical field of jacking gears, the jacking mechanism comprises a shell with an opening formed in the left side, a lead screw is rotationally installed in the shell through a bearing, the right end of the lead screw rightwards penetrates through the shell, a hand wheel is fixedly arranged at the extending end of the lead screw, a sliding block is in threaded connection with the lead screw, and the sliding block is in threaded connection with the right end of the lead screw. Link mechanisms are respectively arranged on the upper and lower sides of the slide block; the connecting rod mechanism located on the upper side comprises a first connecting plate hinged to the top of the sliding block through a first pin shaft, a bent plate is hinged to the other end of the first connecting plate, the middle of the bent plate is hinged to the opening of the shell through a second pin shaft, and a second connecting plate parallel to the bent plate is arranged under the left half portion of the bent plate. And a third connecting plate is hinged between the left end part of the second connecting plate and the left end part of the bending plate. The gear jacking device has the beneficial effects that the structure is compact, the working intensity of workers is relieved, and the gear jacking efficiency is improved.
