The invention discloses a lifting machine with a locking function. The lifting machine comprises a base, a lifting mechanism, a lock rod and a lock groove, wherein the lifting mechanism is arranged onthe base, comprises a rotating shaft rotationally connected with the base, and can perform a lifting motion in a vertical surface around the rotating shaft; the lock rod is rotationally connected with the side surface of the lifting mechanism; the lock groove is formed in the base, and is positioned at the same side of the lifting mechanism with the lock rod; the extension direction of the lock groove and the extension direction of the lock rod are positioned in the same plane; and the lock rod can be rotated to insert in the lock groove, and is butted against the lock groove. Through matching between the lock rod and the lock groove, the lifting position of the lifting mechanism is locked, and the stability of the lifting mechanism is improved.
