[0048] In this embodiment, the angle block magnetic adjustment dial 53 can drive the angle block magnetic lower disc 51 to rotate. Since the magnetic force gear adjustment step top teeth 520 of the angle block magnetic upper disc 52 abut against the magnetic force gear adjustment step bottom teeth 510 of the angle block magnetic lower disc 51, the rotation of the angle block magnetic lower disc 51 can change the distance between the angle block magnetic lower disc 51 and the angle block magnetic upper disc 52, so that the distance between the angle block magnetic upper disc 52 and the angle block magnetic lower disc 51 can be changed, and the angle block magnetic rod 42 can be driven to move up and down, so as to change the distance between the angle block magnetic rod 42 and the rotating core 1, and then the magnetic distance between the sixth magnetic attraction element 43 at the bottom of the angle block magnetic rod 42 and the fifth magnetic attraction element 13 of the rotating core 1 can be adjusted, the magnetic attraction force can be changed, and the function of variable magnetic force can be realized.

[0049] It can be understood that the angle block magnetic adjustment dial 53 can reach different magnetic distances of different gears to form a multi-stage adjustable magnetic force, and the magnetic force of each gear can be fully compatible. The angle block magnetic lower disc 51 is provided with a plurality of annularly distributed and upwardly protruding positioning protrusions, the angle block magnetic adjustment dial 53 is provided with a clamping groove matched with the positioning protrusions, the clamping groove of the angle block magnetic adjustment dial 53 is clamped with the positioning protrusions of the angle block magnetic lower disc 51, the connection between the angle block magnetic adjustment dial 53 and the angle block magnetic lower disc 51 is realized, and the rotation of the angle block magnetic adjustment dial 53 can drive the angle block magnetic lower disc 51 to rotate. Preferably, a gear display number 531 is arranged on the outer wall of the angle block magnetic adjustment dial 53, and a gear adjustment hole 532 is arranged between adjacent gear display numbers 531. The gear display number 531 can be displayed outwardly through the adjustment window arranged on the angle block 4. During actual adjustment, an external tool can be used to tap the gear adjustment hole 532 through the adjustment window according to the direction indicated by the adjustment direction indicating arrow, so that the angle block magnetic adjustment dial 53 is rotated. Through the design of the adjustment window, the gear display number 531, the adjustment direction indicating arrow and the gear adjustment hole 532, the direct display of the gear during magnetic force adjustment can be facilitated, an explicit gear reference for adjustment is given, and the adjustment is facilitated.

[0050] It should be noted that the prism 3 is detachably connected with a prism magnetic rod 38, and the seventh magnetic attraction element is installed in the prism magnetic rod 38.

In addition, since the angle block magnetic rod 42 is detachably connected with the angle block 4 and the prism magnetic rod 38 is detachably connected with the prism 3, when the magnetic attraction element needs to be replaced, the internal components do not need to be disassembled, and only the internal magnetic rod needs to be replaced, so that the effect of replacing the magnetic attraction element can be achieved. In addition, by using the magnetic rod, the structure of the magic cube part can be optimized, and the weight of the magic cube can be reduced.
