The invention discloses an electric trigger type safety tongs device, and belongs to the field of elevator safety. The safety tongs device comprises a supporting body connected with an elevator car and progressive safety tongs moving on the supporting body in the direction perpendicular to the moving direction of the elevator car. The triggering mechanism is arranged on the supporting body and used for driving the progressive safety tongs to move for braking, and the electric reset mechanism is arranged on the supporting body and used for driving the progressive safety tongs to move for braking recovery. The progressive safety tongs comprise a tongs seat installed on the supporting body in a sliding mode, a friction block component which is fixedly installed at the position, corresponding to one side of the lift car guide rail, of the tongs seat and moves to be close to or away from the lift car guide rail along with the tongs seat, and a wedge block which moves to be close to or away from the lift car guide rail on the side, corresponding to the lift car guide rail and away from the friction block, of the tongs seat. The safety tongs device is simple in structure and small in size, can be suitable for being installed and used in a narrow and small space, can achieve timeliness of braking of the elevator car, and guarantees safety of the elevator car.
