Electronic safety gear trigger of elevator

The invention discloses an electronic safety gear trigger of an elevator, which is characterized in that an elastic mechanism is utilized to drive a lifting plate of a safety gear, the elastic mechanism is connected with an electromagnetic chuck, the electromagnetic chuck and the elastic mechanism attract each other to keep the elastic mechanism in a reset state, and the electromagnetic chuck loses magnetism during braking and is separated from the elastic mechanism; the elastic mechanism bounces off and drives the safety tongs to brake; an electric push rod is arranged on the electromagnetic chuck, extends out and pushes the electromagnetic chuck to adsorb the elastic mechanism, and then retracts and pulls the elastic mechanism to a reset state. The electronic safety gear trigger does not adopt mechanisms of a speed limiter, a tensioning device, a speed limiter steel wire rope and a safety linkage device, and is simple in structure, better in stability and reliability and capable of reducing cost. 本发明公开了一种电梯
