Therefore, the present invention is an improvement of the prior art, which substantially lies in the connection relationship between hardware, not in the functions and methods themselves, that is, the present invention relates to a few functions and methods, but does not include the improvements proposed in the functions and methods themselves. The present invention is described for better illustration of the function and method for better understanding of the present invention.

As shown in fig. 1, 2 and 3, in one embodiment, the present invention provides a magnetic ball joint, including a first connecting member 100 and a second connecting member 200; the first connecting piece 100 and the second connecting piece 200 are connected in a spherical hinge connection mode, so that the rotational freedom degree of the connecting joint is higher, the rotary motion of a universal spherical hinge can be realized, and the requirement of toys such as dolls on the high-freedom-degree rotation of the joint is met; specifically, first connecting piece 100 one end is equipped with link 110, and second connecting piece 200 is equipped with the spread groove 210 with the adaptation of link 110 block with the relative one end of connecting piece, makes link 110 can wind spread groove 210 free rotation, and link 110 of first connecting piece 100 can the activity card go into in the spread groove 210 of second connecting piece 200, because link 110 and spread groove 210 constitute the block cooperation, link 110 can be free rotation in spread groove 210, and first connecting piece 100 and second connecting piece 200 can constitute the ball pivot structure that can freely adjust the angle.

As shown in fig. 1, fig. 2 and fig. 3, further, in the present embodiment, a connection cavity 120 is disposed in the connection end 110, and a connection magnet 300 is disposed in the connection cavity 120; the inner wall of the connection groove 210 is provided with a magnetic attraction portion 400 capable of magnetically attracting the connection magnet 300. The connecting magnet 300 inside the connecting end 110 can attract the magnetic attraction portion 400 on the inner wall of the connecting groove 210, and under the condition that the connecting magnet 300 and the magnetic attraction portion 400 attract each other magnetically, the firmness of connection between the first connecting piece 100 and the second connecting piece 200 can be ensured, so that the first connecting piece 100 and the second connecting piece 200 can be stably positioned by the magnetic attraction manner after being adjusted to corresponding angles. When in use, the connecting difficulty and the manufacturing cost of the toy joint can be reduced, the toy is convenient to disassemble and assemble, and the assembling efficiency of the toy is improved.

As shown in fig. 1, 2 and 3, in order to form a ball hinge connection between the connection end 110 and the connection slot 210, in the embodiment, the connection end 110 is arranged in a sphere, and the connection end 110 arranged in a sphere is movably clamped into the connection slot 210, so that the rotation range of the first connection member 100 can be increased. Further, the connecting cavity is also arranged in a spherical shape, and the spherical center of the connecting end 110 and the spherical center of the connecting cavity 120 are overlapped with each other. Thus, the spherical shape of the connection cavity and the connection end 110 are overlapped to ensure the consistent wall thickness of the hollow part of the connection end 110, so that the magnetic attraction force between the connection magnet 300 and the magnetic attraction part 400 in the connection cavity 120 is equal. In order to facilitate the insertion of the connecting magnet 300 into the connecting cavity 120, the first connecting member 100 may be provided with a mounting hole communicating with the connecting cavity 120, and the mounting hole may be closed, and further, the first connecting member 100 may be formed by assembling detachable members so as to open the connecting cavity 120 for the insertion of the connecting magnet 300.

In practical applications, the connecting magnet 300 is preferably a permanent magnet, the connecting magnet 300 may be arranged in a sphere, and the magnetic attraction portion 400 is a magnetic material capable of being attracted by the connecting magnet 300; and the first connecting member 100 and the second connecting member 200 use non-magnetic members, thereby ensuring stable attraction between the connecting magnet 300 and the magnetic attraction portion 400.
