The hook 30 is rotated about the fastening bolt 34 by the hook spring 33 so that the hook fitting port 31 faces the door pin 14.

In addition, a hooking jaw 32 is formed on the outer circumferential surface of the hook 30, and the locking piece 40 is rotated around the fastening bolt 41 on the upper portion of the substrate 20 so as to be caught by the hooking jaw 32. . When the locking piece 40 is caught by the locking jaw 32, the hook 30 cannot be arbitrarily rotated. At this time, the hook fitting holes 31 and the substrate fitting holes 21 cross each other at right angles to each other, and the doors are formed at the intersections thereof. When the pins 14 are fitted, the doors 11 are rotated about the hooks 30 and the fitting holes 31 and 21 and the door pins 14 of the substrate 20 to open and close.

In addition, the lower portion of each substrate 20 is provided with a wire catching hole 52 which is fastened to the fastening bolt 41 of the lock piece. And these wire catching opening 52 is connected to each other through the control lever 50 and the wire 51 provided in the center of the door (11). And the wire catching port 52 is always rotated in one direction through the wire spring 53 so that the lock piece 40 is in close contact with the hook 30. When one of the control levers 50 is rotated and the upper and lower wires 51 are pulled, the wire catching holes 52 connected to the wires are rotated, respectively, and the lock pieces 40 are connected to the fastening bolts 41.
