The elevator escape car door expander comprises a fixing frame, a first clamp and a second clamp, the second clamp is movably installed on the outer surface of the rear end of the fixing frame, and the first clamp is movably installed on the side, close to the second clamp, of the outer surface of the rear end of the fixing frame. A two-way lead screw used for driving the first clamp and the second clamp to move is movably installed in the middle of the inner side of the fixing frame, a fixing clamping plate is fixedly installed in the middle of the front end of the fixing frame, and a rotary clamping sleeve used for driving the two-way lead screw to rotate is movably installed on the inner side of the fixing clamping plate. The screw groove clamping piece drives the first clamping tool and the second clamping tool to move towards the two sides, so that the first clamping tool and the second clamping tool complete the expansion operation on the elevator door, by means of the arrangement of the rotary clamping sleeve and the two-way lead screw, a user can complete the expansion operation on the elevator door through the lead screw structure, and the time needed for rescue of the compartment type elevator is shortened.
