Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 5 As shown, the utility model provides a scanning head adjustment structure based on a scanner, including a working box 1 and a base 10, the inside of the working box 1 is fixedly connected to a first servo motor 2, the end of the output shaft of the first servo motor 2 is fixedly connected to a main shaft 3, the outside of the main shaft 3 is fixedly connected to a small gear 4, the outside of the small gear 4 is meshingly connected to a large gear 5, the inside of the large gear 5 is fixedly connected to a rotating shaft 6, one end of the rotating shaft 6 is fixedly connected to a connecting rod 7, the outside of the connecting rod 7 is fitted with a support rod 8, and the outside of one end of the connecting rod 7 is fixedly connected to a scanning head body 9.

[0026] Specifically, a worm 12 is rotatably provided inside the base 10, a worm wheel 13 is meshedly connected to the outside of the worm 12, a threaded rod 14 is fixedly connected to the inside of the worm wheel 13, the threaded rod 14 passes through the base 10, and the top end is embedded in the inside of the support frame 24, a sleeve 15 is spirally connected to the outside of the threaded rod 14, a connecting plate 16 is sleeved on the outside of the sleeve 15, and one side of the connecting plate 16 is fixedly connected to one side of the working box 1.

[0027] Furthermore, a support seat 17 is sleeved on the outer side of the main shaft 3, and a bearing 18 is embedded in the interior of the support seat 17, and the bearing 18 is sleeved on the outer side of the main shaft 3. Under the action of the bearing 18, the friction coefficient between the main shaft 3 and the support seat 17 is reduced, thereby ensuring the rotation accuracy of the main shaft 3.

[0028] Furthermore, a limiting rod 25 is fixedly connected to one side of the large gear 5 , and two limiting rods 25 are symmetrically arranged around the central axis of the large gear 5 , so as to limit the rotation angle of the large gear 5 .

[0029] It is worth mentioning that a fixed block 19 is fixedly connected to the inner bottom surface of the working box 1, and a blocking rod 20 is fixedly connected to one side of the fixed block 19, and the blocking rod 20 is located in the middle position of the two limit rods 25. The blocking rod 20 will block the limit rod 25 when the large gear 5 drives the limit rod 25 to rotate, thereby limiting its rotation angle and preventing the scanning head body 9 from being damaged due to excessive angle.

[0030] It is worth noting that one end of the worm 12 is fixedly connected to a second servo motor 11, and the second servo motor 11 is fixedly connected to the inside of the base 10. The second servo motor 11 drives the worm 12 to rotate without the need for manual shaking by staff, thereby reducing the staff's workload and improving work efficiency.

[0033] Among them, the first servo motor 2, the scanning head body 9, the second servo motor 11 and the scanner body 22 are existing technologies and will not be described in detail; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0034] Working principle and process:

[0035] When the staff is scanning a large object, if it is inconvenient to rotate the object angle, the staff can start the first servo motor 2 inside the working box 1, so that the first servo motor 2 drives the main shaft 3 to rotate. Under the action of the bearing 18, the friction coefficient between the main shaft 3 and the support seat 17 is reduced, thereby ensuring the rotation accuracy of the main shaft 3 and reducing energy consumption. The main shaft 3 drives the small gear 4 to rotate, and the small gear 4 drives the large gear 5 to rotate. One side of the large gear 5 is fixedly connected with two limit rods 25, which can limit the rotation angle of the large gear 5. The blocking rod 20 will block the limit rod 25 when the large gear 5 drives the limit rod 25 to rotate, limit its rotation angle, and prevent the scanning head body 9 from being damaged by excessive angle. The large gear 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the connecting rod 7 to rotate. The connecting rod 7 rotates inside the support rod 8, and the support rod 8 supports it. The connecting rod 7 drives the scanning head body 9 to rotate, thereby realizing the deflection angle of the scanning head body 9, and can scan the sides of some objects that cannot be moved, increase the scanning range, and make the scanner Practicality is increased. If the height of the scanning head body 9 is not enough, the second servo motor 11 inside the base 10 will drive the worm 12 to rotate, and there is no need for the staff to manually shake it, which reduces the work intensity of the staff and improves work efficiency. The worm 12 drives the worm wheel 13 to rotate, and the worm wheel 13 drives the threaded rod 14 to rotate. The threaded rod 14 drives the sliding sleeve 15 to rotate, and the sliding sleeve 15 drives the connecting plate 16 to move upward. Under the action of the optical rod 21, the movement of the connecting plate 16 is more stable, and no jitter or deviation occurs, which plays a guiding role in its movement. The connecting plate 16 drives the working box 1 fixedly connected to one side thereof to move upward, so that the scanning head body 9 can move upward, and the height of the scanning head body 9 is adjusted, so that the scanning range of the scanning head body 9 is increased, which is conducive to scanning objects of different heights and increasing practical performance. A protective pad 23 is fitted on the top of the scanner body 22. When placing an object, under the action of the protective pad 23, the scanner body 22 can be protected to prevent normal damage to it from friction and increase its service life.
