[0036] The second adjusting member includes a second gear 17, a second toothed plate 18 and a second motor 16. The second gear 17 is fixedly connected to the outer wall of the second arm 4. The second gear 17 is placed on one side of the second toothed plate 18 and meshes with the second toothed plate 18. The second motor 16 is installed on the outside of the movable sleeve 3. The output end of the second motor 16 is fixedly connected to the second gear 17.

[0037] comprehensive Figure 2, the working principle of the second regulating member is:

[0038] The second motor 16 drives the second gear 17 to rotate, and the second gear 17 engages with the second tooth plate 18 during rotation to push the second tooth plate 18. Since the second tooth plate 18 is fixed to the second arm 4, when the second tooth plate 18 is pushed, the second arm 4 will also move and slide up and down along the inner wall of the movable sleeve 3.

[0039] For the specific structure of the first adjusting member, please refer to the following description.

[0040] The third adjusting member includes an electric push rod 7, a first articulated seat 5 and a second articulated seat 6.

[0041] comprehensive Figure 3 , the working principle of the first regulating member is:

[0042] The lower end of the movable sleeve 3 is hinged to the first arm 1 through the first hinge seat 5. When the electric push rod 7 pushes the movable sleeve 3, the angle between the movable sleeve 3 and the first arm 1 is expanded, and the scanning frame 8 on the second arm 4 falls downward. When the electric push rod 7 pulls the movable sleeve 3, the angle between the movable sleeve 3 and the first arm 1 is reduced, and the scanning frame 8 on the second arm 4 is lifted upward.

[0043] How this application works:

[0044] The fixed sleeve 2 is sleeved on the outside of the first arm 1 and fixed to the external frame.
