[Technical field to which the invention pertains] The present invention relates to a hinge structure, and more particularly to a keyed structure of an electronic device. [Prior Art] A common electronic device, such as a notebook computer, a flip-type mobile phone, and an electronic (four) code, usually requires a hinge structure to connect the cover body and the main body. In the process of using the notebook computer, it is usually required that the cover body can be positioned at an arbitrary angle of β to facilitate the user's operation, which requires a certain friction between the internal components of the hinge structure. The hinge structure on the electronic device comprises a main shaft, a friction member fixed on the main shaft, a follower sleeve sleeved on the main shaft and rotatable relative to the main shaft, and a sleeve sleeved on the element. The friction member has a friction surface which is a curved surface. The driven member has a driven surface and a limiting groove, and the driven surface is a rotating curved surface abutting on the friction surface of the friction member, and the bracket is provided with a finite position ❹ protrusion, and the limiting protrusion and the upper limit of the driven member The slot fits to limit the range of angles of rotation of the follower relative to the bracket. The frictional force is generated by the frictional surface engagement between the friction member and the driven member, so that the cover body stays at an arbitrary angle. Further, an elastic member that abuts against the driven member is further disposed on the main shaft, and the elastic member can maintain a certain frictional force after the use of the follower member and the friction member for a long time. In order to make the connection of the electronic device more secure, and at the same time save the space of the joint, usually in the case of satisfying the strength of the hinge structure, the two ends of the joint are arranged with as small a hinge structure as possible. However, the hinge structure of the 5 201010581 moving member, the friction member and the elastic member are sleeved on the main shaft, and the sleeve is sleeved on the above components, so the sleeve of the hinge structure has a large volume and inner • Diameter, which inevitably results in a larger overall size of the hinge structure, which in turn affects the appearance of the electronic device. If the diameter of the main shaft is reduced to reduce the overall size of the hinge structure, the strength of the main shaft will be reduced, thereby shortening the use of the hinge structure. SUMMARY OF THE INVENTION In view of the above circumstances, it is necessary to provide a hinge structure that is small in size and durable. A hinge structure includes two rotating components and an elastic member disposed between the two rotating components and connected to the two rotating components. The rotating component comprises a main shaft, a sleeve sleeved outside the main shaft, and a friction disposed between the main shaft and the sleeve The elastic member elastically connects the two rotating components to abut the friction member with the sleeve. The elastic member of the hinge structure is disposed outside the rotating component, and the two rotating components share an elastic member to generate an elastic force for abutting the friction member and the sleeve, thereby reducing the overall volume of the rotating component and thereby reducing The overall volume of the Qin key structure. In addition, when wear occurs between the friction member and the sleeve, the elastic member can keep the friction member and the sleeve still in a state of mutual abutment, thereby prolonging the service life of the hinge structure.
