A lifting mechanism with self-locking function, including an ascending/descending seat, a rocking member pivotally connected with the ascending/descending seat, a guide section and a prestressing section. The rocking member serves to convert a horizontal force provided by a power source into a vertical force to up and down reciprocally move the ascending/descending seat in the direction of Z-axis. The guide section includes guide members, which can be cross roller ways for guiding the ascending/descending seat to ascend/descend. The prestressing section can be adjusted to change the gaps between fixed guide rails and movable guide rails of the cross roller ways. Accordingly, the sliding friction between the fixed guide rails and the movable guide rails can be adjusted to provide auxiliary locking force for locating the ascending/descending seat.
