[0031] The camera module 9 is compressed by the second compression spring 55 and the first compression spring 45 . It is sufficient to select a spring with appropriate pressure without requiring a pressure sensor, which greatly reduces the cost and makes control more convenient.

[0032] The first clamping device 4 includes a first clamping seat 41, a first clamping block 43 and a first clamping plate 46. The first clamping seat 41 is installed on the first slider, and the first slider is slidably installed on the first linear guide rail.

The fourth magnet 68 can be made of iron or a fourth magnet. The magnet can be a strong magnet. In order to reduce the impact on the camera module 9 and prevent the compression of the wire, the top pressing plate 61 is provided with a rubber plate 65 which is arranged opposite to the wire and the camera module 9 and is used to press the wire on the camera module 9. The top pressing plate 61 is also provided with a welding groove 60 which leaks the position to be welded, thereby facilitating laser welding.
