The self-locking strength is designed according to the weight and size of the notebook screen to design the appropriate resistance force. For example, the shaft design has a -5 degree self-locking, and the screen will usually close automatically when it is 10-20 degrees. The screen and the keyboard will completely fit, there will be no opening phenomenon, reducing the internal structure of the electronic product, which is beneficial to improve the space utilization of the product rate.
