The invention relates to a totally encapsulated type antiseptic sucker rod specific elevator and a using method thereof. The totally encapsulated type antiseptic sucker rod specific elevator comprises an elevator body, a loose piece, a closing piece, a closing piece shaft, a loose piece shaft and a lifting ring, the two side walls of a semiarc-shaped main body of the elevator body are provided with lifting ring shafts, and are connected to the lifting ring through the lifting ring shafts, the two ends of the semiarc-shaped main body are provided with a closing piece female shaft seat and a closing piece male shaft seat respectively, the center of the semiarc-shaped main body is provided with a semicircular sucker rod through hole, the closing piece female shaft seat is connected to the closing piece through the closing piece shaft, the closing piece male shaft seat is connected to the loose piece through the loose piece shaft, the loose piece cooperates with the semiarc-shaped main body to achieve chucking and loosening of a sucker rod, and the closing piece cooperates with the loose piece to achieve chucking and loosening of the loose piece. The totally encapsulated type antiseptic sucker rod specific elevator and the using method thereof have the advantages that an antiseptic layer at the flange portion of the sucker rod is prevented from being damaged when a normal sucker rod elevator is during the work construction of lifting and laying down the totally encapsulated type antiseptic sucker rod, accordingly downhole using of the totally encapsulated type sucker rod is protected, the using cycle is prolonged, the rejection rate and production cost of the sucker rod are reduced, and the economic benefit is improved.
