摘要
The door lock comprises a bolt made of metal or other material mounted on a base attached to the door. Part of the bolt may be received in a hole in the door frame, in order to fasten the door. The end of the bolt away from the door frame has a tab attached to the base situated at either end of the tab attached to the bolt. - Each shaft has a cut-away portion and a button with an indicator arrow on top allowing it to be rotated to a marked position. Each indicator arrow moves over a scale of letters or numbers, so that the setting may be identified. By rotation of the two buttons the bolt may be locked or unlocked.(0/0)
