When using the anti-shake structure of the above structure, since a plurality of balls 70 are arranged between the lens support 30 and the frame 40, when the lens support 30 moves relative to the frame 40 in the Z direction, the lens support can be guaranteed by the balls 70. The 30 can move more flexibly, and can also reduce the frictional force between the lens support 30 and the frame 40 . Since the lens support body 30 is also provided with the guide column 31, during the movement of the lens support body 30 relative to the frame 40, the ball 70 contacts the guide column 31 and the frame 40 at the same time, thereby ensuring the stability of the movement of the ball 70. Thus, the stability of the movement of the lens support body 30 is ensured. Therefore, this arrangement can reduce the shaking of the lens support body 30 during the movement of the lens support body 30 relative to the frame 40 , ensure the stability of the lens support body 30 , and thus ensure that the image captured by the camera device is more stable.
