The turntable 2 drives the turntable 3 to rotate at the same angle in the same direction. When rotated by 180°, the drive element 2223 of the turntable 3 contacts the driven element 2224 of the turntable 4 in its clockwise direction.

At this time, it is only necessary to know that the unlocking opening 22290 of the unlocking groove 2229 of the turntable 4 is at an angle with the control portion 2231 in the clockwise direction with the corresponding turntable as a vertex, and rotate the turntable 4 in the direction.

The effect of the size of the drive element 2223 and the driven element 2224 on the angle of rotation is not considered in the above-described calculation of the specific angle value in the clockwise and counterclockwise directions. Those skilled in the art will appreciate that when the drive element 2223 and the driven element 2224 are small in size, their effect on the angle of rotation is negligible. When it is large in size, it can also become an important factor affecting the password of each turntable 222. An example of the above angle is based on the fact that the dimensions of the drive element 2223 and the driven element 2224 do not affect the angle of rotation. Those skilled in the art should understand that the above examples are merely illustrative of the invention and are not intended to limit the invention.
