The invention relates to an elevator synchronous gate knife. The problem that a general synchronous gate knife is unreasonable in structure, not easy to debug, long in opening time and likely to be clamped is solved. The synchronous gate knife comprises a track frame and a base plate. A stop arm, a transmission arm and a lock plate are hinged to the back face of the base plate. A guide wheel is arranged at the front end of the stop arm. Rotating arms are hinged to the upper portion and the lower portion of the front face of the base plate respectively. The upper rotating arm is in linkage with the transmission arm through a drawing rod. One ends of the rotating arms are hinged to a first blade, the other ends of the rotating arms are hinged to a movable plate, an unlocking rotating arm is hinged to the movable plate, a second blade is hinged to one end of the unlocking rotating arm, and the other end of the unlocking rotating arm abuts against the lock plate. The elevator synchronous gate knife has the advantages that the mechanical structure is simplified, one blade integrates the closing function and the unlocking function, the precision requirement for adjusting the matched position between the gate knife and a hall gate ball is lowered, and debugging is easier. The problem that a closing tail end blocking hall gate mechanical reopening time is too long or the system is halted is solved.
