[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model, by setting a threaded strip, sleeve, side plate, and locking block, addresses the issue of incorrect installation of the rebound device within the cabinet, causing the cabinet door to fail to close properly. By rotating the rotating ring, the threaded strip drives the locking block to move left and right, which in turn pushes the sleeve to move left and right. Furthermore, when the device is unstable or subjected to extremely rapid impact, the annular groove provides an initial buffering force to the movable column as it moves. The locking block's movement to the right generates a second buffering force through rotation. This method is simple to operate, reduces external forces, and prevents damage to objects inside the cabinet.

[0013] 2. This utility model, by setting up a hook, an inlet slot, an outlet slot, and a U-shaped slot, allows the cabinet door to be pressed. When the door is pressed, the movable column is pushed to the right, and the hook can wrap around the buckle. The hook passes along the side wall of the Y-shaped boss through the inlet slot and finally stops at the turning point of the Y-shaped boss, thereby clamping the buckle by limiting the hook. Pressing again will release the hook from the lock, and the spring will push the movable column to reset, thereby releasing the buckle. This method saves time and effort, has a neat appearance, and expands the use of space. Attached Figure Description
