     This application claims priority of Chinese Patent Application No. 201610633120.4 with a filing date of Aug. 4, 2016 and Chinese Patent Application No. 201620841341.6 with a filing date of Aug. 4, 2016. The content of the aforementioned applications, including any intervening amendments thereto, are incorporated herein by reference. 
     TECHNICAL FIELD 
     This invention relates to a magnetic absorption structure and magnetic blocks applying such structure, and particularly relates to a magnetic absorption structure characterized in the automatic adjustment of the magnetic poles and simple structure when the structures are used in pair as well as the magnetic blocks applying such structure. 
     BACKGROUND OF THE PRESENT INVENTION 
     Magnetic absorption structures are used very widely in daily life. They are often used for apparatuses that need flexible connection to facilitate very easy combination and separation of the devices. The magnetic absorption structure characterized in the automatic adjustment of the magnetic poles can be used very conveniently, as it involves no manual adjustment of the structure. The American patent numbered U.S. Pat. No. 7,154,363B2 dated Dec. 26, 2006 discloses a magnetic connecting part (hereafter referred to as technical background 1) characterized in that a cylindrical magnet is divided into two parts along the surface passing the central axle, one part is the S pole, the other is the N pole, and the cylindrical magnet is arranged in the chamber. When two magnetic connecting parts are used in pair, the two parts of the two magnetic connecting parts that are the closest to one another are different in polarity, namely, when one side is the S pole, the other side will be the N pole. The magnetic connecting part of the structure must use a cylindrical magnet. Therefore, the outer surface of the magnet is a cambered surface When two parts move close to one another, the distance between the magnets of the two magnet connecting parts is the smallest in the middle but gradually rises upward or downward, which will lead to a decline of the absorption force as result of the unreasonable design of the structure. The American patent numbered U.S. Pat. No. 6,749,480B1 and dated Jun. 15, 2004 discloses a device that applies a magnet on a multitude of polygon structures (hereafter referred to as technical background 2). It is characterized in that different polarities are set on the two end surfaces of a cylinder to assure that when two devices absorb one another, the two end surfaces can rotate to realize an absorption connection between the devices. This structure solves the disadvantages of the American patent numbered U.S. Pat. No. 7,154,363B2. However, the structure is relatively complex and involves relatively high processing precision in order to assure smooth rotation. At the same time the complex structure itself will increase the cost and the high processing precision will further increase the cost together with the nonconformity rate and an environmental damage. Now, it is imperative to design a magnetic absorption structure characterized in the automatic adjustment of the magnetic poles and simple structure when the structures are used in pair as well as the magnetic blocks applying such structure.

     This invention can be implemented to achieve the following benefit: 
     This invention relates to a magnetic absorption structure comprising a magnetic part and a supporting part supporting the said magnetic part The said magnetic part comprises a magnet, the said magnet comprises an absorption surface, the said absorption surface contains at least one S pole and one N pole, and the said magnetic part can rotate in relation to the said supporting part. When a pair of magnetic absorption structure are used together and brought to one another, if the polarity of the absorption surface of one magnetic absorption structure does not remain in the position of mutual absorption with the polarity of the absorption surface of the other magnetic absorption structure, the magnetic part or parts of one or two of the magnetic absorption structures will rotate in relation to the supporting part until the S pole or N pole of the absorption surface of one magnetic absorption structure corresponds to the N pole or S pole of the absorption surface of the other magnetic absorption structure. It can be seen that when the magnetic absorption structures adopting this structure are used in pair, at least an S pole or N pole on the absorption surface of one magnetic absorption structure will create a mutual absorption with the N pole or S pole on the absorption surface of the other magnetic absorption structure to generate an absorption force. This represents a fundamental difference from the magnetic absorption structure said in technical background 2: When it works, only one polarity of one magnetic absorption structure will create a mutual absorption with one polarity of another magnetic absorption structure. Compared to technical background 2, the magnetic absorption structure said in this invention is characterized in a simple structure and easy absorption between two structures when they are used in pair. At the same time, the structure also avoids a possible damage to the magnet when the two end surfaces of the magnet in technical background 2 rotate back and fro. Also, this invention can use a thin magnet, while the polarities of the magnet are arranged on the two end surfaces of the cylindrical magnet in technical background 2. Therefore, the magnet in technical background 2 involves certain thickness requirement in order to magnetize the magnet smoothly. In contrast, this invention can use a relatively thin magnet, so it can be used for occasions that involve a significant restriction over height and space. Compared to technical background 1, given the same magnetic force requirement, the distance is roughly the same and short between the absorption surfaces of the magnets under this invention. Therefore, when the magnet with the same magnetic force is used, the magnetic absorption structures said under this invention can create a bigger absorption force when they are used in pair. For this reason, the magnet under this invention can have a smaller volume, which makes this invention possible to serve various occasions setting the least volume requirement. 
     The outermost profile of the said magnetic part is round. The said supporting part comprises an accommodating part accommodating the said magnetic part. The said accommodating part is a chamber. The said chamber is a cylindrical chamber. This structure can assure smooth rotation of the round magnetic part in the accommodating part, thereby assuring that when the magnetic absorption structures are used in pair, the polarity on the absorption surface of one magnetic absorption structure and that on the absorption surface of the other magnetic absorption structure can smoothly rotate to the position of mutual absorption, thereby realizing the absorption between the two magnetic absorption structures. 
     The said magnetic part comprises a rotating part and the said supporting part comprises a rotation supporting part matching the said rotating part. When the said rotating part is an axle, the said rotation supporting part will be a hole, and when the said rotating part is a hole, the said rotation supporting part will be an axle. The rotating part of the magnetic part and the rotation supporting part of the supporting part can match one another to assure the smooth rotation of the magnetic part in relation to the supporting part. This will further assure that when the magnetic absorption structures are used in pair, the polarity on the absorption surface of one magnetic absorption structure and that on the absorption surface of the other magnetic absorption structure can smoothly rotate to the position of mutual absorption, thereby realizing the absorption between the two magnetic absorption structures. 
     The said magnetic part comprises a magnetic part supporting element, and the said magnet and the said magnetic part supporting element are connected. The said supporting part comprises a magnet accommodating area, and the said magnetic is arranged in the said magnet accommodating area The said magnet accommodating area is cylindrical and the said magnet is a cylindrical magnet. The design of the magnetic part supporting element avoids directly processing the rotating part on the magnet, thereby increasing the processing cost of the magnet and making it possible to directly use magnets in general shapes for this invention, which will cut the cost. At the same time, the cylindrical magnet can rotate in the cylindrical magnet accommodating area. This will further assure that when the magnetic absorption structures are used in pair, the polarity on the absorption surface of one magnetic absorption structure and that on the absorption surface of the other magnetic absorption structure can smoothly rotate to the position of mutual absorption, thereby realizing the absorption between the two magnetic absorption structures. 
     A magnetic block using the aforesaid magnetic absorption structures characterized in that the the block comprises a block body, a chamber is set within the said block body, and the said magnetic absorption structure is arranged within the said chamber. The magnetic absorption structures are set in the chamber. When two blocks are brought towards one another, the polarity positions on the absorption surfaces of the magnetic absorption structures in the two block bodies will rotate, thereby assuring smooth abortion of the blocks. Compared to technical background 2, the structure under this invention is more reasonable and realizes smoother adjustment of polarities and simpler structure, which will not increase the processing difficulty while assuring smooth adjutant of polarities. This will not only reduce the chance of nonconforming products but also cut down the production cost. The the said block body consists of N panels, the said N panels enclose the said chamber, and N is a natural number. A magnetic absorption structure is set near the inner surface of at least one panel, the absorption surface of the magnetic absorption structure faces a nearby inner surface. This structure can set corresponding number of magnetic absorption structures based on concrete demand, thereby satisfying the need to use magnetic blocks. The said supporting part is connected with the said block body. The said supporting part comprises at least one supporting part base arranged on the inner surface of the panel and one supporting part body set on the said supporting part base. The said supporting part body comprises a supporting arm, and the said rotation supporting part is set on the said supporting arm. The said supporting part base is set on a panel, and the said supporting part body is connected with the said supporting part base. The said supporting part base is provided with a coupling gap, and the said supporting part body is coupled with the said coupling gap to realize the connection with the supporting part base. This structure will facilitate processing and installation. 
     N is 6, there are six magnetic parts, a corresponding magnetic part is set near the inner surface of said every panel, the absorption surface of the magnetic part faces the inner surface of the corresponding panel, and the said supporting part comprises at one supporting part base arranged on the inner surface of the panel and one supporting part body set on the said supporting part base. A groove is set in the position where the said supporting part body and the said coupling gap match one another, and the side wall of the said coupling gap is embedded into the said groove. A compression structure is set on the opposite panel of the panel where the supporting part base is set, and the said compression structure props against the supporting part body. There are four said coupling gaps, and every two of the four said coupling gaps are set opposite to one another. The said supporting body comprises six supporting arms, and the ends of the said six supporting arms face the inner surfaces of the said six panels. The said six supporting arms are connected, and the included angle is 90 degrees between every two adjacent supporting arms of the said six supporting arms. The said compression structure comprises two compression boards set in parallel, the ends of the said compression boards are provided with compression grooves, and the said compression grooves props against the said supporting part body. This hexahedron block assures that when it is used together with another magnetic block setting a magnetic absorption structure, the polarity on the absorption surface of any magnetic part on any surface will automatically adjust. At the same time, this structure will facilitate processing and assembly. When magnets are installed into the accommodating part, the positions of all magnets can be automatically adjusted through the absorption force or repulsive force, and the generated absorption force will assure that the magnets installed into the accommodating part will not easily drop out and also assure that the magnetic part will not easily shed when it is assembled with the supporting part. At assembly, the supporting part can be further assembled with assembled parts, and then directly put in the chamber. This structural design also increases the assembly efficiency. 
     N is 2, the entirety of the said block body is a cone, there is one said magnetic part, and the absorption surface of the magnetic part faces the inner surface of the panel located on the bottom face, N is 3, the said block body is a cylinder there are two said magnetic parts, the absorption surface of one magnetic part) faces the inner surface of the panel located on the bottom face, and the absorption surface of the other magnetic part faces the inner surface of the panel on the top surface.

N is 5, there are five said magnetic parts, the said block body is a tetrahedron, and the absorption surface of the magnetic part near the inner surface of every parcel faces the inner surface of the panel. When N is 1, the said block body is sphere or any other shape consisting of cambered surfaces. This will assure that during actual use, the value of N can be determined based on concrete demand to satisfy the use of magnetic blocks.
