有些具有立體鑰匙孔的廣

鎖稱為「迷宮鎖」或「定向鎖」,

其鑰匙孔位於底面接近端面的

直角處,開鑿成「工」字形。

這類鎖具的特徵是:其鑰匙不

容易直接插入鑰匙孔。

Some broad locks with spatial

keyholes are called "labyrinth locks"

or "fix-orientation locks". They

have their keyholes located at the

vertical corner formed by the bottom

side and one side-end of the lock-

body with the shape of a "

" letter.

The main characteristic of this type

of locks is that it is not easy to insert

the key into the keyhole.
