before the device is used, the device is assembled, as shown in fig. 5, wherein the upper end of the device is seen from the upper right to the lower left of fig. 5, and the front side of the device is seen from fig. 5 (as the connecting sheet 10 of the hinge of the device is provided with a plurality of different countersunk bolt holes, the mounting form of the device is enlarged, and meanwhile, the device can be mounted by turning up and down, the direction of the device is limited, and the description is only convenient);

when the device is used, the hinge is arranged on a notebook computer keyboard frame and a notebook computer display board, one end of the ring shaft sleeve 11, which exceeds the connecting sheet 10, is kept on the outer side, so that the installation surface of the notebook computer keyboard frame and the inner surface of the notebook computer display board can be positioned on the same horizontal plane when the device is opened, thereby playing a role in beauty, when the device is opened and closed, the two connecting sheets 10 drive the respective ring shaft sleeves 11 to rotate around the axes of the ring shaft sleeves 11 (a fixed reference system is not taken firstly, only the distance and the approach of the outer edges of the two connecting sheets 10 are considered), the two ring shaft sleeves 11 rotate around the hinge screw rod 12 (as shown in figures 5 and 6, wherein the hinge screw rod 12 is screwed in the ring shaft sleeves 11 on the outer side, and the ring shaft sleeve 11 on the outermost side is fixedly arranged on one of the connecting sheets 10 at the same time, so that when the connecting sheets 10 rotate, the ring shaft sleeve 11 is also driven to rotate, the ring shaft sleeve 11 rotates to drive the hinged lead screw 12 to rotate, so that the hinged lead screw 12 and the ring shaft sleeve 11 which is in threaded connection with the hinged lead screw 12 are in a relative static state, so that the hinged lead screw 12 cannot rotate with the ring shaft sleeve 11 which is in threaded connection with the hinged lead screw, and the problem that the hinged lead screw 12 is loosened and the hinge fails due to the fact that the connecting sheets 10 are opened and closed for multiple times is avoided, wherein when the ring shaft sleeves 11 which are respectively fixed by the two connecting sheets 10 rotate slowly relative to each other (the action of a notebook computer is slow), the adjusting block 17 at the upper end rotates along with the ring shaft sleeve 11 at the upper end to drive the adjusting sleeve 16 at the lower end to rotate together, the adjusting sleeve 16 rotates to drive the torsion spring 20 at the lower end to rotate by overcoming the self torsion, so that the wave ring plate 18 at the lower end of the torsion spring 20 extrudes the wave ring teeth 19 at the end of the ring shaft sleeve 11 at the lower end, the wavy annular plate 18 and the wavy annular teeth 19 at the lower end are extruded in a staggered manner, so that resistance is applied to the rotation between two adjacent annular shaft sleeves 11, the connecting piece 10 rotates to generate resistance, when the wavy annular teeth 19 and the wavy annular plate 18 are meshed again, the wavy annular teeth 19 and the wavy annular plate 18 can slide, the torsion spring 20 is recovered, the resistance of opening the notebook computer can be kept unchanged all the time, and the damping effect is achieved; when the notebook computer is started rapidly, because the rotating speed between the ring shaft sleeves 11 is too high, the wave ring plate 18 and the wave ring teeth 19 at the lower end cannot slide rapidly in time (the torsional spring 20 can generate a pressing acting force between the wave ring plate 18 and the wave ring teeth 19 at the lower end to a certain extent, and the wave ring plate 18 and the wave ring teeth 19 at the lower end rotate rapidly, so that the wave ring plate 18 and the wave ring teeth 19 at the lower end are meshed and cannot separate and unload force), the torsion of the torsional spring 20 is increased, the rotating speed of the two connecting pieces 10 is prevented, a speed limiting effect is achieved, and the situation that the display panel of the notebook computer impacts the keyboard frame of the notebook computer or other external objects is avoided;
