The stepped portions 723 are located on the surface of the limiting cover 72 facing away from the compression spring 71. The convex blocks 441 are arranged in cooperation with the stepped portions 723, and the convex blocks 441 abut against the stepped portions 723. Rotate the adjusting block 44 so that the convex blocks 441 move on the stepped portions 723, realizing driving the limiting cover 72 to reciprocate back and forth along the length direction of the connecting shaft 11, changing the compression state of the compression spring 71, and thus adjusting the axle distance of the corner block body 4.The cross-section of the bump 441 is triangularly shaped, such that the bump 441 can only rotate in one direction on the stepped portion 723. A third identifier 443 that matches the rotation direction of the bump 441 is provided on the surface of the adjusting block 44 facing away from the limiting cover 72, so as to facilitate the rotation of the adjusting block 44. A second scale 412 is provided at the opening of the limiting cover 411. The second scale 412 is arranged in cooperation with the stepped portion 723. The distance between the axial pitches of the adjacent two stepped adjustment corner block bodies 4 of the stepped portion 723 is 0.1 mm. A second identifier 442 pointing to the second scale 412 is provided on the side wall of the adjusting block 44, so as to facilitate observing the size of the axial pitch of the corner block body 4. The corner block bottom shell 41 is provided with a placement groove 415, and the magnetic member 51 is placed in the placement groove 415, so as to facilitate the interaction of the magnetic member 51 between the magnetic member 51 of the clamping shell 23 and the center block shell cover 22, making it easier to align and position the corner block body 4 and the center block body 2, thereby optimizing the experience of playing with the pyramid Rubik's Cube. The corner block shell cover 42 is provided with a plugging rod 421. The plugging rod 421 is inserted into the placement groove 415. On the one hand, the assembly of the corner block shell cover 42 and the corner block bottom shell 41 is realized. On the other hand, the plugging rod 421 restricts the magnetic member 51 in the placement groove 415 from coming out. The wall of the placement groove 415 is provided with a fastening hole 416, and the side wall of the plugging rod 421 is provided with a buckle 422 that matches the fastening hole 416. The buckle 422 is snapped into the fastening hole 416 to restrict the plugging rod 421 from coming out of the placement groove 415. The side wall of the corner block shell cover 42 is provided with a clamping cavity 423. The clamping cavity 423 is a dovetail groove. The side wall of another corner block shell cover 42 is provided with a clamping strip 424 that matches the clamping cavity 423. The clamping strip 424 is snapped into the clamping cavity 423. Not only the assembly of the two corner block shell covers 42 is realized, but also the two assembled corner block shell covers 42 are more fixed. The clamping cavity 423 and the clamping strip 424 are respectively arranged on both sides of the corner block shell cover 42, so as to facilitate the assembly of the adjacent two corner block shell covers 42.
