[0002] In the Rubik's Cube competition, a more complex Rubik's Cube is usually used as a competition prop. During the competition, the contestants need to rotate it quickly in order to complete the reordering of the Rubik's Cube in the shortest time. The traditional Rubik's Cube relies on the player's precise rotation when rotating, and the Rubik's Cube needs to be rotated at a specific angle each time, so that the Rubik's Cube is not easy to get stuck. The Rubik's Cube with a magnetic positioning mechanism uses magnetic suction to make the corner blocks of the Rubik's Cube be magnetically attracted when it is rotated at a specific angle, making the positioning more accurate.

[0003] However, the existing magnetic positioning mechanism has the following technical problems:

[0004] (1) The magnetic attraction structure of the Rubik's Cube products is top-positioned, that is, the magnet is set inside the block, resulting in too small a torque required to overcome the magnetic force when rotating the Rubik's Cube, which in turn has a great impact on the speed of the Rubik's Cube restoration;

[0005] (2) The existing magnetic attraction structure has too many magnets inside each block, which makes it heavy and difficult to achieve explosive speed, affecting the consumer experience;

[0006] (3) The magic cubes on the market do not have a multi-level magnetic force structure that can adjust the gears after replacing the magnets, and therefore cannot effectively be fully compatible with multi-level magnetic forces. Summary of the invention
