Body-building intelligence-promoting magic cube

The invention discloses a body-building intelligence-promoting magic cube. A fixed shaft is arranged in the center of a magic cube body; the lower end of the fixed shaft is inserted into a hole on the upper part of a supporting column fixed on a ground pedestal and locked by using a set screw; the fixed shaft sequentially penetrates through a thrust bearing, a lower central block, a lower supporting sleeve, a cross shaft, an upper supporting sleeve and an upper central block from bottom to top, and the top of the fixed shaft is locked by using a round nut and covered by a square cover plate; the cross shaft, the lower central block and the upper central block can respectively rotate around the fixed shaft; four lateral central blocks are sleeved at each end of the cross shaft, and each outer end of the cross shaft is locked by using a round nut and then covered by a square cover plate; twelve prismatic blocks and eight angle blocks are arranged and embedded between the central blocks to form a large cube; and
