The screw rod 3 is connected with one support through small-pitch threads, and one end of the screw rod extends out of a threaded hole of the support and abuts against the other support. In the figure, the screw 3 is connected to the screw hole of the first bracket 1 and abuts against the second bracket 2. When the camera is applied, the distance between the first support 1 and the second support 2 can be adjusted by rotating the screw rod 3, so that the focal depth or the optical axis angle of the camera can be adjusted.

Specifically, all the screws 3 are rotated in the same direction, so that the second support 2 moves relative to the first support 1 along the optical axis direction, and the focal depth of the camera can be adjusted. Only the screw 3 on one side of the optical axis of the camera is rotated, or the screw 3 on one side of the optical axis is rotated and the screw 3 on the opposite side is rotated in the opposite direction at the same time, so that the second support 2 is deflected relative to the first support 1, and the angle of the optical axis can be adjusted.

Specifically, the end face of one end of the screw rod 3, which abuts against the bracket, may be configured as an arc surface, and the arc surface is used to contact the bracket. Thus, the stent is not easily damaged. The arc surface may be formed by fitting a universal ball 4 into one end of the screw rod 3 as shown in fig. 3, which is easier to implement than directly machining the arc surface on the screw rod 3.

Specifically, as shown in fig. 4 or 5, a set of screws 3 may be disposed on two sides of a first plane a on which an optical axis of the camera is located, and a set of screws 3 may be disposed on two sides of a second plane b perpendicular to the first plane a on which the optical axis is located. One or more screws 3 are grouped. In this way, the second holder 2 can be tilted in two mutually perpendicular directions relative to the first holder 1, which ensures that the target position can be adjusted no matter at what angle the optical axis was at before the adjustment.

With the arrangement, under the action of the elastic force of the elastic piece 7, the relative positions of the first support 1 and the second support 2 are more stable, so that the accuracy of a detection result is easier to ensure.

Specifically, the elastic member 7 and the screw rod 3 are staggered with each other, so that the force points of the screw rod 3 and the elastic member 7 on the bracket are distributed dispersedly, and the relative positions of the first bracket 1 and the second bracket 2 can be more stable.

In particular, the elastic element 7 and the support can be connected in the following way: the two ends of the elastic piece 7 are provided with connecting rings, the first support 1 and the second support 2 are provided with embedding holes, the connecting rings are embedded into the embedding holes of the first support 1 and the second support 2, the first support 1 and the second support 2 are provided with radial threaded holes communicated with the embedding holes, and second fastening screws 11 are arranged, the second fastening screws 11 are connected into the radial threaded holes of the first support 1 or the second support 2, and one end of each of the second fastening screws 11 extends out of the radial threaded holes to penetrate into the connecting rings. The reliability of this connection is high.

For a linear array camera, the linear array direction and the scanning direction need to be adjusted to be perpendicular to each other during scanning. Therefore, as shown in fig. 2, an adapter cylinder 8 can be further arranged, the lens 02 is connected to the adapter cylinder 8, the second support 2 is sleeved on the periphery of the adapter cylinder 8 and is connected with the adapter cylinder 8 through a small-pitch thread, so that the second support 2 can rotate relative to the adapter cylinder 8, and as the second support 2 is connected with the first support 1 through the bolt 10, the first support 1 and the body 01 mounted on the first support 1 can also rotate together when the second support 2 rotates, so that the linear array direction can be accurately adjusted to be perpendicular to the scanning direction.
