The folding screen mobile phone is a mobile phone with a flexible and flexible screen, which is also called as a winding mobile phone because of being shaped like a winding. Compared with a traditional screen, the folding screen has the advantages of being obvious, lighter and thinner in size, lower in power consumption than original devices, beneficial to improving the cruising ability of equipment, and meanwhile based on the characteristics of good flexibility and flexibility, the durability of the folding screen is greatly higher than that of the traditional screen, and the probability of accidental damage of the equipment is reduced.

To realize the folding function of the folding screen, besides the screen itself, the design of the connecting component for realizing folding, namely the connecting shaft at the bending position, is also the biggest technical problem. Considering the particularity of the folding screen, the traditional rotating shaft has no way to meet the functional requirements, a special rotating shaft of the folding screen is needed to assist the realization, the folding screen is bent according to the application requirements and is divided into two bending requirements of an outer bending and an outer bending, and the requirement of the inner bending mechanism is higher.
