The invention discloses a follow-up self-locking jack. The jack comprises a jacking system, a follow-up self-locking mechanism and a hydraulic reset mechanism, the jacking system is used for moving inthe horizontal or vertical direction, the follow-up self-locking mechanism is movably connected with the jacking system, and the jacking system is communicated with an oil path of the follow-up self-locking mechanism through the hydraulic reset mechanism. The follow-up self-locking mechanism keeps the locking trend of the jacking system in the up-and-down movement jacking adjustment process of the jacking system, and the jacking system is locked immediately after up-and-down movement jacking adjustment of the jacking system is completed. The follow-up self-locking mechanism is simple and easyto control in control mode, high in effectiveness, high in safety, capable of achieving double-acting hydraulic reset and capable of saving installation space. By means of the follow-up self-lockingjack, through the hydraulic reset mechanism, the jacking system communicates with the oil path of the follow-up self-locking mechanism, so that the automation degree of the whole control process is higher, and manual intervention is not needed.
