Problems solved by technology

[0002] At present, in order to realize the close fit between the box cover and the box body in packing boxes such as suitcases and protective boxes, the zipper is generally used to cooperate, but the zipper is easy to be disengaged due to local force, resulting in the closure of the box cover and the box. The cooperation between the boxes is realized, causing the internal storage items to fall out of the box or even be damaged, and the protection effect is poor
Although some locking devices are also used to realize the tight fit between the box cover and the box body, generally speaking, these locking devices have problems of locking, inconvenient opening and use, low opening and closing efficiency, and unreliable and easy locking. Leading to accidental opening, easy misalignment between the box cover and the box body, poor sealing, and the items inside the box cannot be effectively protected
