[0002] Building block games are very popular among young children. They involve children using building blocks to play games, with building as the main activity. In the process of building blocks, children can develop various abilities. They can use their hands and brains together to exercise their hand dexterity and hand-eye coordination.

[0003] Existing technologies have specifically developed some mortise and tenon detachable building block toys. For example, Chinese patent with announcement number "CN219815275U" discloses "A detachable tank building block toy based on mortise and tenon structure". By setting up a simple structure and assembling the building blocks in a predetermined order, it is possible to disassemble the building blocks only through a single degree of freedom after assembly. This ensures the stability of the building blocks while improving their educational value, and also has the logic of disassembly and assembly as well as aesthetic appeal.

[0004] Although the simple structure and predetermined assembly order of the building blocks ensure stability and enhance their educational value, while also providing logical assembly and disassembly and aesthetic appeal, the inability of the turret to rotate effectively reduces the playability of the building block toy and fails to effectively increase children's interest in completing the assembly.
