Since the movable door 6 is installed on the right side panel 4 through the door spring hinge, the movable door 6 will automatically close under the action of the door spring, and the movable door 6 can squeeze the movable block 81 into the connecting groove 9. The toggle block 85 is set at the right end of the shaft rod 82. 85 is rotatably connected with both ends of the movable shaft 84 through bearings. When the toggle block 85 rotates, it can pull the movable shaft 84, and then the movable shaft 84 pulls the shaft rod 82, and the shaft rod 82 pulls the movable block 81, so that the movable block 81 is located in the movable inner groove 7, and the movable door 6 is separated from the left side plate 4. When the toggle block 85 is pulled, the movable block 81 is located in the movable inner groove 7 inside the movable door 6. At this time, the return spring 83 is compressed. When the toggle block 85 is released, the return spring 83 is reset to make the movable block 81 pop out of the movable inner groove 7.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
