when the door is left-opening, the left ratchet catch 19 is engaged with the ratchet 17 by removing the screw between the ratchet 17 and the left ratchet catch 19 of the ratchet 17.

Specifically, as shown in fig. 11(a) and 11(b), two ratchet catches 19 are provided at corresponding positions on both sides of the ratchet area of the ratchet 17, and when the screw between the ratchet catches 19 and the ratchet 17 is removed, the ratchet catches 19 define the rotation direction of the ratchet 17 by the urging force exerted by the ratchet catch return springs 20.

The foregoing description of the specific embodiments of the invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes and modifications may be made by those skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
