Guide shaft can be followed to rotate freely；Simultaneously as it is linear structure that spiral-straight line axle sleeve one end, which is the spiral other end,
The linear motion of a fixed spacing can also be done when rotation, it is screw that the two, which combines, after the stroke of linear motion,
It is just only simple to rotate in place movement.
The purpose for designing unlocking mechanism in this way is, just can only be clockwise after being clamped block clamping wait stopper of locking,
It cannot reverse, so, when clamping block is stuck when on stopper of locking, stopper to be locked will not be caused inverse due to vibration etc.
Turn, and wait lock stopper due to vibration jolts etc. clockwise when then stopper to be locked can be made to be locked the clamping block in mechanism
That blocks is tighter, so that clamping block can be constantly in stuck state with stopper to be locked；And in practical applications, this unlocking mechanism
And the mechanism for locking up being used cooperatively with this unlocking mechanism is typically mounted on bus door, subway door or high iron gate etc.,
It is opposing stationary between door, so this unlocking mechanism can effectively avoid the stopper to be locked (i.e. car door) locked from being expert at
During sailing due to vibration automatic unlocking, structure is simple, and mechanism design is reasonable.
