[0025] By providing a clamping component 4, it can adapt to the opening and closing angle and automatically adjust the damping size. When in use, the slider 44 is sunk into the slide groove 42, and the roller 43 is in rolling contact with the ring 41. The resistance between the roller 43 and the ring 41 makes the second rotating shaft 3 and the main shaft 1 maintain a certain resistance. As the opening and closing angle of the screen and the keyboard changes, the distance between the roller 43 and the ring 41 is changed to adjust the resistance between the second rotating shaft 3 and the main shaft 1. The resistance changes during the opening and closing process, and the reliability is high.

[0026] See also Figures 1 to 4 The collar 41 is fixedly connected to the surface of the first rotating shaft 2, the slide groove 42 is opened on the surface of the collar 41, the roller 43 is slidably connected to the surface of the collar 41, the slider 44 is fixedly connected to the surface of the roller 43, the connecting shaft 45 is rotatably connected to both sides of the roller 43, the connecting plate 46 is fixedly connected to the outer side of the connecting shaft 45, the two ends of the telescopic rod 47 are respectively fixedly connected to the connecting shaft 45, the two ends of the torsion spring 48 are respectively fixedly connected to the connecting shaft 45, the slider 44 is located inside the slide groove 42, and the model of the slider 44 is consistent with that of the slide groove 42, the slider 44 is located inside the slide groove 42, and the model of the slider 44 is consistent with that of the slide groove 42;

[0027] Then when the angle between the screen and the keyboard reaches 15 to 80 degrees, the distance between the roller 43 and the ring 41 increases, causing the slider 44 to disengage from the slide groove 42, reducing the force on the torsion spring 48, thereby reducing the resistance between the second rotating shaft 3 and the main shaft 1. At this time, the screen can be easily opened. When the angle between the screen and the keyboard is greater than 80 degrees, the roller 43 and the ring 41 roll again and contact, and the force increases again. At this time, a certain force is required to continue to open the screen, and the opening and closing angle can be adaptive.

[0028] See also Figures 1 to 3A housing assembly 5 is provided on the surface of the main shaft 1, a protective shell 51 is rotatably connected between the first rotating shaft 2 and the second rotating shaft 3, a plurality of reinforcing rods 52 are fixedly connected to the inner wall of the protective shell 51, one end of the reinforcing rod 52 is fixedly connected to a connecting sleeve 53, the connecting sleeve 53 is sleeved on the surface of the main shaft 1, a first fixing plate 6 is fixedly connected to the surface of the first rotating shaft 2, a second fixing plate 7 is fixedly connected to the surface of the second rotating shaft 3, a nut 8 is fixedly connected to one end of the first rotating shaft 2, and a gasket 9 is fixedly connected to the surface of the first rotating shaft 2;

[0029] The protective shell 51 is wrapped around the surface of the main shaft 1 to form a closed space, thereby preventing dust from entering and causing dust accumulation on the main shaft 1 .

[0030] In the utility model, the working principle of the device is as follows:

[0031] When in use, the first rotating shaft 2 is connected to the laptop computer host through the first fixing plate 6, and the second rotating shaft 3 is connected to the laptop computer screen through the second fixing plate 7. When working, first, the torsion force of the torsion spring 48 presses the roller 43 to the main shaft 1 through the connecting shaft 45. When the screen is buckled on the keyboard, the slider 44 is sunk into the slide groove 42, and the roller 43 is in rolling contact with the ring 41. The resistance between the roller 43 and the ring 41 keeps a certain resistance between the second rotating shaft 3 and the main shaft 1, so that the screen is stably buckled on the keyboard. Then, when the screen is lifted up, the angle between the screen and the keyboard is less than 15 degrees. , the roller 43 keeps rolling contact with the collar 41, so that a certain force is required to open the screen. Then, when the angle between the screen and the keyboard reaches 15 to 80 degrees, the distance between the roller 43 and the collar 41 increases, so that the slider 44 is disengaged from the slide groove 42, so that the force on the torsion spring 48 is reduced, thereby reducing the resistance between the second rotating shaft 3 and the main shaft 1. At this time, the screen can be easily opened. When the angle between the screen and the keyboard is greater than 80 degrees, the roller 43 and the collar 41 are in rolling contact again, and the force increases again. At this time, a certain force is required to continue to open the screen. It can adapt to the opening and closing angle and automatically adjust the damping size.
