Abstract
The present utility model discloses a safety lock device including a first lock body and a second lock body. The first lock body is provided with a movable member, a first action member and a second action member. The second action member and the first action member are operated sequentially to enable the movable member to act to unlock. The first action member or the second action member is operated individually that cannot achieve the unlocking. The unlocking of the safety lock device is completed only by fitting the two moving members with each other, thereby solving the problems of the easy unlocking by children and the potential safety hazards.
