The invention discloses a lead screw anti-shake supporting device and a machine tool comprising the same. The lead screw anti-shake supporting device comprises a lead screw, a movable part, a first control part, a second control part and a lead screw supporting part, wherein the two ends of the lead screw are movably arranged on a main frame; the first control part and the second control part are arranged on the movable part; when the first control part is separated from and contacted with the second control part along with the movement process of the movable part, the lead screw supporting part is firstly in a state of being clamped with the lead screw during separation and provides support for the lead screw; during contact, the first control part drives the second control part to move away from the lead screw in the direction perpendicular to the lead screw, so that the lead screw supporting part is driven to be separated from the lead screw, it is guaranteed that the movable part can support the lead scre
