Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The staff can connect the six mounting shells 1 end to end by installing the threaded nail 301 of the mounting shell 1 in the threaded hole 201 on the surface of the arc-shaped bottom plate 2 of the adjacent mounting shell 1. The adjacent mounting shells 1 support each other, thereby improving the stability of the mounting shell 1 installation and making the disassembly and assembly flexible. By adjusting the position of the threaded nail 301 of the mounting shell 1 installed in the threaded hole 201 on the surface of the arc-shaped bottom plate 2 of the adjacent mounting shell 1, the distance between two adjacent mounting shells 1 can be adjusted, and the diameter of the ring formed by the six mounting shells 1 can be adjusted.

[0019] A magnetic tile unit 4 is installed inside the installation shell 1, and a plurality of semicircular grooves 401 with equal spacing are arranged on the outer walls on both sides of the magnetic tile unit 4. Elastic positioning structures 5 for fixing the magnetic tile unit 4 are installed at both ends of the installation shell 1. The elastic positioning structure 5 includes two springs 501 installed at both ends of the installation shell 1. An abutment block 502 is installed at one end of the two springs 501 away from the inner wall of the installation shell 1. A semicircular protrusion 503 for plugging with the semicircular groove 401 is arranged on the outer wall of the abutment block 502 away from the spring 501.

[0020] The two springs 501 elastically support the abutment block 502 to abut against the magnetic tile monomer 4, and the semicircular protrusions 503 are inserted into the semicircular grooves 401 on both sides of the magnetic tile monomer 4 to improve the stability of the installation shell 1 to install the magnetic tile monomer 4;

[0021] Connecting rods 6 are installed at the center of the top and bottom of the mounting shell 1. The connecting rods 6 are L-shaped and made of stainless steel. A rotor 7 is installed between the outer walls of the two opposite sides of the two connecting rods 6. The surface of the rotor 7 and the outer wall of one side of the magnetic tile monomer 4 are in contact with each other.

[0022] By flipping the connecting rods 6 at the top and bottom of the mounting shell 1, the twelve L-shaped connecting rods 6 abut the top and bottom of the rotor 7 respectively, and the six mounting shells 1 and the magnetic tile monomers 4 are installed on the surface of the rotor 7, thereby improving the installation firmness of the six mounting shells 1 and the magnetic tile monomers 4.

[0023] When the embodiment of the present application is in use, the staff first installs the magnetic tile monomer 4 inside each mounting shell 1, and the elastic positioning structures 5 at both ends of the mounting shell 1 press the outer walls of the two sides of the magnetic tile monomer 4, then flip the connecting rods 6 at the top and bottom ends of the mounting shell 1, and make the outer walls of the opposite sides of the connecting rods 6 at the top and bottom ends of the mounting shell 1 respectively abut the two ends of the rotor 7, and then each mounting shell 1 is installed on the surface of the rotor 7, and finally adjust the arc-shaped top plate 3 on the top side of the mounting shell 1 to be installed in the position of the threaded hole 201 of the arc-shaped bottom plate 2 on the bottom side of the adjacent mounting shell 1, and fix the two adjacent mounting shells 1 through the threaded hole 201 by means of a threaded nail 301, so as to connect the six mounting shells 1 end to end, and adjust the distance between the two adjacent mounting shells 1 by adjusting the position of the arc-shaped bottom plate 2 installed on the arc-shaped top plate 3, so as to change the diameter of the annular structure formed by the six mounting shells 1, so that the mounting shells 1 are connected end to end. The mounting shell 1 can be installed on rotors 7 of different diameters, thereby improving the flexibility and application range of the mounting shell 1. Two adjacent mounting shells 1 support each other, and the stability of the structure of the six mounting shells 1 can also be improved. The six connecting rods 6 clamp the two ends of the rotor 7, thereby ensuring that the mounting shell 1 and the magnetic tile monomer 4 are firmly installed on the surface of the rotor 7. The magnetic tile monomer 4 is clamped and fixed by the elastic positioning structure 5 at both ends inside the mounting shell 1. The movable end of the elastic positioning structure 5 is provided with a semicircular protrusion 503 that is clamped with the semicircular grooves 401 at both ends of the magnetic tile monomer 4, which can improve the stability of the movable end of the elastic positioning structure 5 clamping the magnetic tile monomer 4, and the magnetic tile monomer 4 is placed inside the mounting shell 1 to slide. The connecting rod 6 hinged at the top and bottom ends of the mounting shell 1 can also fix the two ends of the magnetic tile monomer 4 when clamping the two ends of the rotor 7, thereby preventing the magnetic tile monomer 4 from slipping out of the inside of the mounting shell 1.
