The device can adjust the camera 101 to have three degrees of freedom: horizontal angle, pitch angle, and rotation angle. The camera 101 is mounted on the rotating plate 103. By loosening the first limiting member and rotating the first knurled step hand screw 106 clockwise, the camera 101 can be adjusted by rotating the rotating plate 103 on the tilt plate 105. At 05:00, the third limiting member 112 is released, and the tilt plate 105 is rotated for adjustment. After adjustment, the position is limited by the first locking bolt 110. When adjusting the adjustment plate 113, the second limiting member 109 is released, and the adjustment plate 113 on the mounting plate 107 is rotated.

[0024] Using the horizontal adjustment mechanism of a line scan camera according to this utility model, the device can adjust the camera 101 to three degrees of freedom: horizontal angle, pitch angle, and rotation angle. The camera 101 is mounted on the rotating plate 103. By loosening the first limiting member and rotating the first knurled step hand screw 106 clockwise, the camera 101 rotates and adjusts on the elevation plate 105 along with the rotating plate 103. When adjusting the elevation plate 105, the third limiting member 112 is loosened, and the elevation plate 105 is rotated for adjustment. After adjustment, the position is limited by the first locking bolt 110. When adjusting the adjustment plate 113, the second limiting member 109 is loosened, and the adjustment plate 113 on the mounting plate 107 is rotated.
