The invention discloses an elevator protection mechanism. The elevator protection mechanism comprises a crank arm and a stroke switch. The crank arm has the connection end and the work end, wherein the connection end is connected with a wall of a floor in a rotating mode. The crank arm can rotate around the connection end in the horizontal direction. When an elevator door is opened, the work end of the crank arm can rotate into an elevator car. The stroke switch is arranged at the work end. The crank arm with the stroke switch rotates in a blind area outside the infrared ray light curtain area, and the stroke switch is connected with an elevator power source. According to the invention, when the elevator door is opened, the crank arm slides into the elevator car, once accidents happen to an elevator and the elevator rises or drops, the stroke switch controls the elevator power source to be cut off in time, the elevator car can be supported by the crank arm, and therefore the accidents can be reduced. In addition, the elevator protection mechanism is easy to install, whether the elevator protection mechanism is operated safely can be directly seen, and therefore the safe use environment can be provided for users.
