[0002] At present, multiple drawers of items such as traditional boxes, cabinets and tables are generally controlled by a lock. When the lock is opened, all drawers are in the state of being opened, and each drawer can be opened and closed. On the contrary, all drawers must be closed. , before the lock can be locked. At present, there is a drawer with an anti-multiple opening structure that can only open one drawer at a time. This kind of drawer is equipped with an anti-dodging device on the side rail of the drawer. This device is made of plastic. , the structural strength is not high, and it is easily damaged. If the device is damaged, the anti-multi-opening structure will not work

At present, there is an interlocking device installed on the inside of the drawer cabinet on the market. The interlocking device is a mounting plate structure. It is necessary to install a fixed piece on the inner side of each drawer, and drive the interlocking strip on the interlocking piece through the fixed piece to lock other drawers. However, since this interlocking device is installed on the inner side of the drawer box, it needs to be installed Space for installing the interlock device is reserved on the inner side of the drawer box, and Yunci occupies the space of the drawer, which increases the volume of the box
