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.
