摘要： A lower locking pin body for the hinge joint between a lower locking pin and a lower locking pin hook has a suspending hole of a coupler lock lifter to facilitate it rotating surrounding the lower locking pin hook under the effect of the hole. There are two coupler suspending holes which are respectively arranged on each side ends of the lower locking pin body to facilitate the workers opening the coupler on either side of a car. A two-side operating coupler with above said lower lock pin body and a draft gear are provided, wherein the draft gear also includes two lock lifters and two lock lifter seats. The lock lifters are mounted into a key-shaped hole of the lock lifter seats, and the lock lifter has a limiting segment on the matched position. Two hook head ends of the lock lifters pass respectively out from the key-shaped holes of the coupler lock lifter seats and hang with the coupler lock lifter suspension hole of the two-side operating coupler. It has clearance between the limiting segment of the coupler lock lifter and a stripe-shaped hole wall of the key-shaped hole.
