The bottom end of the torsion friction strip 17 is slidingly connected to the support seat 18 through the elastic metal support seat 19. The four support seats 18 are fixedly connected to the two first SYS brackets 10 and the two second SYS brackets 11. Under the support action of the support seat 18, the elastic metal support seat 19 can continuously elastically support the torsion friction strip 17, thereby facilitating the torsion friction strip 17 to squeeze the shaft core 15 in rotation.
[0023] See also Figure 3 and Figure 4 The rotating shaft 12 includes a central locking plate 14 and an axis core 15. The central locking plate 14 and the axis core 15 are integrally machined. A semicircular plate is provided at one end of the LCD bracket 8. The central locking plate 14 and the semicircular plate are fixedly connected by two locking screws 9. The outer surfaces of both ends of the axis core 15 are provided with spiral grooves. Both ends of the axis core 15 are inserted into the inner side of the torsion groove 16. The lower end surfaces of both ends of the axis core 15 are provided with flat sections. The axis core 15 is in contact with the upper end surface of the torsion friction strip 17 through the flat sections. When the flat sections are in contact with the torsion friction strip 17 and the torsion groove 16 at different angles, the torque adjustment of the notebook at different opening and closing angles can be achieved.
[0024] See also Figure 1 and Figure 2 The computer cover 3 is fixedly installed on one end of the LCD bracket 8 away from the rotating shaft 12, and the display screen 4 is fixedly installed on one side of the computer cover 3. The computer bottom case 1 is fixedly installed on one side of the strip protective cover 5. The keyboard case 2 is fixedly installed on the upper end surface of the computer bottom case 1. Two end corners of the computer bottom case 1 are fixedly connected to the two first SYS brackets 10 and the two second SYS brackets 11. The first connecting component 6 and the second connecting component 7 are symmetrically installed relative to the center of the strip protective cover 5. The strip protective cover 5 protects the first connecting component 6 and the second connecting component 7 to achieve dust prevention and avoid pinching of hands.
[0025] During use, the first connecting assembly 6 and the second connecting assembly 7 are symmetrically installed relative to the center of the strip-shaped protective cover 5. Specifically, the first connecting assembly 6 and the second connecting assembly 7 each include a first SYS bracket 10 and a second SYS bracket 11. The first SYS bracket 10 and the second SYS bracket 11 are fixed to two end corners of the computer bottom case 1 by screws. The rotating shaft 12 includes a central locking plate 14 and an axis core 15. The two ends of the axis core 15 are plugged into the inner sides of the first SYS bracket 10 and the second SYS bracket 11. An LCD bracket 8 is installed on one side of the first SYS bracket 10 and the second SYS bracket 11. A semicircular plate is provided at one end of the LCD bracket 8. The semicircular plate is fixedly connected to the central locking plate 14 by two locking screws 9.

[0027] When the laptop cover 3 is opened and closed, the cover 3 is synchronously driven by the two LCD brackets 8 to rotate the shaft 12 inside the torsion groove 16. The lower end surfaces of both ends of the shaft core 15 are provided with flat cut surfaces, and the flat cut surfaces are in contact with the upper end surfaces of the torsion friction strips 17. When the shaft core 15 rotates, the flat cut surfaces separate from the torsion friction strips 17 and squeeze the torsion friction strips 17. The rotational interference between the shaft core 15 and the torsion groove 16 can facilitate the stabilization of the opening and closing angle of the computer cover 3.
[0028] Under the support of the support seat 18, the elastic metal support seat 19 can continuously elastically support the torsional friction strip 17, thereby facilitating the torsional friction strip 17 to rotate and squeeze the shaft core 15. When the flat section on the shaft core 15 contacts the torsional friction strip 17, the rotational torque of the rotating shaft 12 gradually increases. When the flat section on the shaft core 15 contacts the inner wall of the torsional groove 16, the rotational torque of the rotating shaft 12 is constant.
