At the same time, the first carrier 31 is rotated by an angle relative to the third carrier 35 by the two second hinges 341, and is tilted by the two first hinges 321 relative to the 201029550 body 10 - The first washers 322, 323 and the first connecting end 311, the first hinge shaft 321 and the slot sidewalls 111 of the first mounting slot n generate frictional resistance, so that the first carrier 31 The frictional resistance generated by the second washers 322, 323 also maintains the second carrier 33 in a level state, thereby maintaining the display screen in a parallel state with the body 10. Referring to FIG. 8 together, the display screen 2 〇 (not shown) is rotated 90 degrees relative to the body 10 to rotate the third carrier 35 relative to the second carrier 33 by the third hinge shaft 371. degree. The state is maintained by the frictional resistance generated by the washer 372 and the second twisted shaft 371 and the third carrier 35. Please refer to FIG. 9 together and then tilt the display screen 2 to the keyboard area and resist the first carrier 31. At this time, the second carrier 33 is rotated by the second hinge shaft 341 and the first carrier. 31 is on the same plane, and the state is maintained by the frictional resistance of the second washers 342, 343, so that the display screen 20 is kept in an inclined state 'and the outer screen 2〇1 and the keyboard area 1〇2 are at a certain angle 'It is convenient for users to watch and operate. Please refer to Figure 10 together. It can be understood that the number of the first hinge shaft 321, the second hinge shaft 341 and the two connecting shafts 361 may be one; the number of the first washer 322, the second washer 342, 343 and the washers 362, 363 are correspondingly change. The number of the first connecting end 311, the hinge end 312, the second connecting end 333 and the third connecting end 352 is changed accordingly. The rotating mechanism 30 drives the rotation of the display screen 20 by the second hinge portion 34 and the third hinge portion 37; the rotation of the first hinge portion 32 relative to the body 10 and the first hinge portion 32 and the second hinge portion 34 and The cooperation of the three hinges 37 11 201029550 enables the display screen 20 to rotate relative to the body 10 to achieve a variety of viewing angles for the user to view and operate. The rotating mechanism has a simple structure and is convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is an exploded perspective view of a mobile phone in a preferred embodiment of a rotating mechanism of the present invention. Fig. 2 is an enlarged schematic view showing another viewing angle of one of the display devices of the mobile phone shown in Fig. 1. Fig. 3 is a perspective exploded view of a rotating mechanism applied to the mobile phone shown in Fig. 1. Figure 4 is an assembled view of the rotating mechanism shown in Figure 3. Figure 5 is an assembled view of the mobile phone shown in Figure 1. Figure 6 is a partial assembled view of the mobile phone shown in Figure 1, wherein the rotating mechanism is assembled on the mobile phone. 7 to 9 are diagrams showing a state of rotation of the rotating mechanism shown in Fig. 6. Fig. 10 is a view showing the state of the display screen device in the state in which the rotating mechanism shown in Fig. 9 is rotated.
