When the lock needs to be closed, push the wrench on the lock ring by hand, and the lock ring will overcome the pull of the large tension spring and extend along the track of the lock shell to the outside of the lock body to enter the other mouth. At this time, the lock is at the tail slot of the lock ring. The lock moves downward along the guide slot under the action of the small tension spring and enters the tail slot of the lock beam. The lock ring is locked by the lock. When the lock moves downward, the lock also drives the eccentric shaft of the lock core to rotate, making the lock core turn back to its original position, and the key can be removed.

When the lock needs to be opened, insert the key into the lock core and turn it clockwise. The rotation angle is limited by the lock core positioning slot. The eccentric shaft behind the lock core rotates in the small rectangular hole on the side of the lock, and the eccentric shaft drives the lock to move upwards {the eccentric shaft and the rectangular hole cooperate to turn the rotation into movement}. The lock moves upward against the pull of the small tension spring under the restriction of the guide plate. When the key is turned to a certain angle, the lock is lifted out of the lock ring tail slot, and the lock ring retracts rapidly into the lock box under the action of the large tension spring, until the lock is opened when the wrench touches the positioning block. After the lock ring is retracted, the lock lock is blocked by the lock ring and cannot fall back to its original position. The lock core is also restricted by the lock lock lock to the position after rotation. The key is stuck by the round bullet in the key tooth and cannot be pulled out of the lock core.
