The invention relates to an elevator provided with multiple safety devices. The elevator comprises an elevator main body (10) and a motor (20), wherein the motor (20) is fixed at the top of the elevator main body (10); two pneumatic push-pull rods (102) are respectively fixed on the two sides in an elevator door guide rail (101) at the top of the elevator main body (10); the other end of each pneumatic push-pull rod (102) is movably connected with the top of an elevator door; a rotating shaft of the motor (20) is connected with a fan impeller (201); a shell of the fan impeller (201) is connected with a ventilating pipe (202); the tail end of the ventilating pipe (202) is connected to the tail part of the corresponding pneumatic push-pull rod (102). The elevator disclosed by the invention is simple in structure and convenient to use; when the elevator door is to be closed and a foreign matter is inserted into the middle of the elevator door, the fan impeller can be driven to exhaust air by the motor; the fan impeller is used for pumping the air in the pneumatic push-pull rods by the ventilating pipe; the pneumatic push-pull rods are used for pulling the elevator door so as to enable the elevator door not to move continuously, and thus clamping injury caused by the elevator door can be prevented.
