Anti-shake module

The invention relates to an anti-shake module, in particular to an anti-shake module capable of reducing displacement friction.

With the evolution of the times, people have become accustomed to taking pictures and recording life. When engaging in activities such as tourism, exhibitions or food gatherings, all of them take the camera to record the beauty of each moment. However, when photographing, the photographer's hand is often shaken, causing the light to enter the internal optical imaging device to shift, resulting in poor image quality of the photo, and when it is desired to re-photograph, the most worthwhile moment has been missed.
