According to the display on the official website of Ma Yuesuo, the lock core of Ma Yuesuo changes the locking principle that the upper and lower bullet holes of the traditional marble lock are inserted into each other into the way of changing the elastic sheet through the rotation angle. The locking principle adopts the integral key locking, which changes the traditional method of locking the marble separately and avoids dislocation and liquid blockage. The lock core is additionally provided with a keyless twist setting. Keys other than this lock can be twisted 360 degrees at will when inserted into the lock hole, but the lock is not opened, and the anti-theft effect is very good.
