That is, the two sleeves in each rotating part are in a concave-convex fit relationship, and when the sleeve provided with the convex part 15 rotates around the guide shaft penetrating through the sleeve, the convex part 15 of the sleeve can rotate along the corresponding circular arc notch 14 to limit the rotating angle of the sleeve, so that the maximum rotating angle of the sleeve is the same as the degree of the central angle corresponding to the circular arc notch 14. During specific implementation, the degrees of the central angles of the three circular arc notches 14 can be set according to actual needs, so that the effect of adjusting the two disassembling angles is achieved. For example, after the third rotating portion rotates by 60 °, the convex portion 15 of the sixth sleeve 12 rotates to one end of the circular arc notch 14 of the fifth sleeve 11 and abuts against the end wall of the circular arc notch 14, so as to lock the sixth sleeve 12, and then the first rotating portion and the second rotating portion rotate until the two detachable components reach the preset state.
As shown in fig. 2, preferably, in order to stably sleeve the second sleeve 6, the fourth sleeve 9, and the sixth sleeve 12 on the first guide shaft 7, the second guide shaft 10, and the third guide shaft 13, respectively, to prevent each sleeve from slipping out of the corresponding connection shaft, and ensure that the corresponding end of each corresponding sleeve abuts against each other, so that each protrusion 15 can completely extend into the corresponding circular arc notch 14, the first guide shaft 7, the second guide shaft 10, and the third guide shaft 13 are further formed with a limiting portion 16 for limiting the positions of the second sleeve 6, the fourth sleeve 9, and the sixth sleeve 12, respectively.

The structure of the stopper portion 16 is not exclusive, and for example, a flange or the like is provided on each guide shaft. The spring is used for the limiting portion 16 in this embodiment because the spring not only can elastically limit the position of the sleeve, but also can increase the rotational resistance of the sleeve, so that the rotation of each rotating portion is more stable, and the detachable member can be positioned at a certain angle after rotating the angle.
The invention also discloses electronic equipment which comprises a first disassembling piece, a second disassembling piece and the rotating shaft mechanism arranged between the first disassembling piece and the second disassembling piece.
As shown in fig. 3, the electronic device in the embodiment is a notebook computer. The notebook computer comprises a first display end 17 and a second display end 18, a control system is integrated in the second display end 18, the display screen of the notebook computer is a touch screen, namely the second display end 18 can be approximately regarded as a flat computer, and a rotating shaft mechanism is arranged between the first display end 17 and the second display end 18 so that the first display end 17 and the second display end 18 can be unfolded and are in a flush state. That is, as shown in fig. 4, fig. 5 and fig. 6, the notebook computer in this embodiment may be used as a normal notebook computer in the prior art, specifically, a software program may be set in the second display terminal 18 to enable the second display terminal to display a keyboard, and a user may tap the keyboard displayed on the screen through the touch screen to achieve an input effect, that is, the second display terminal 18 becomes an information input platform, and may set the program to enable the information input platform to meet diversified information input requirements, such as text input, handwriting input or input of a simulated musical instrument. When in use, only the third rotating part can be rotated to make the included angle between the first display end 17 and the second display end 18 be 90 degrees or 110 degrees, and the maximum rotating angle can be adjusted by limiting the degree of the central angle corresponding to the circular arc notch 14 of the fifth sleeve 11. When the user wants to enlarge the screen of the notebook computer, as shown in fig. 7, 8 and 9, the user can exit the input mode of the second display terminal 18 to make it in the display mode, and then when the third rotating part rotates to the locked state, the first rotating part and the second rotating part are rotated until the screens of the first display terminal 17 and the second display terminal 18 are flush with each other, that is, are in the same plane, and the specific rotating angle can also achieve the adjustment effect by limiting the angle value of the central angle corresponding to the circular arc notch 14 of the second sleeve 6 and the fourth sleeve 9.
After the rotating shaft mechanism is applied to the notebook computer, the notebook computer can be used as a common notebook computer, and the screen area can be increased as required, so that the notebook computer not only meets the requirement of convenience in carrying of a user, but also can meet the requirement of a large screen.
