Or close. In the notebook computer, the basic function of the hinge structure is to allow the opening angle of the carcass to be adjusted according to the user's needs, and the cover body can stay and remain stationary when the cover body is adjusted to an appropriate angle. Conventional drum chain constructions typically achieve these basic functions by friction between the rotating members. In many hinge structures, the friction between the rotating members is small due to wear, and the folded electronic device using the lining structure is easy to loosen after the use period. When the cover is in the open state, it cannot be stably stopped at any angle within the allowable range, and it cannot be used any more. τ [ SUMMARY OF THE INVENTION] In view of the above, it is necessary to provide a hinge structure that allows a folded electronic device body to stably stay at any angle within an allowable range. 1 set.

It can be understood that the engagement of the snap ring ^ with the groove 111 can also be replaced by other snap fits, such as threading. A thread may be provided on the main shaft 10 from the shaft portion u to match the nut with the thread to prevent the main shaft 10 from coming out of the receiving cavity (1) of the bracket 60. When assembling, the shaft portion u of the main shaft 1G is sequentially passed through the friction member. 2 = wide-gasket 41, shrapnel group 50, larger diameter hole 614 of the second spacer is inserted through the larger diameter hole ... and rut; ot = 615. The snap ring 70 is snapped into the shaft portion 11 In the groove 111, the two sides 25T of the main shaft are connected to the first end surface 611 of the bracket 60 by the continent=face 25.
