Problems solved by technology
[0002] With the development of modern science and technology, robot technology has been widely used in various fields. Most robots are equipped with multi-degree-of-freedom mechanical arms, which can complete the required work through expected actions. Nowadays, most of the mechanical arm joints are one joint. The degree of freedom, driven by a motor, can only realize the deflection of one orientation, and to achieve multiple degrees of freedom, it can only be realized by connecting multiple joints in series. This method will inevitably increase the overall structural size of the applied manipulator , thus increasing the space and weight of the manipulator, and in some special applications, the structure of the manipulator is required to be as simple as possible and flexible, and this type of structure will be subject to certain restrictions
[0003] In addition, the applied mechanical arm joints cannot be easily increased or decreased by adding or reducing joints after the design is completed, so as to achieve the increase or decrease of its degrees of freedom, in order to deal with some special application occasions

The invention discloses a wire transmission type universal ball joint. Through application of a cross universal joint and reasonable structural matching, one joint and multiple degrees of freedom can be achieved. By means of the joint, the structure of a mechanical arm is more compact, the overall size and weight of the mechanical arm are reduced, and the flexibility is greatly improved. According to the universal ball joint, modularization of the joint is achieved through a simple structure, the number of the joints can be conveniently increased in the mechanical arm, and therefore the flexibility of the mechanical arm is improved. The universal ball joint is high in universality and can be applied to mechanical arms in various occasions, so that work which cannot be achieved by many conventional mechanical arm structures is completed.
